Microscopic depictions of vanishing shampoo foam examined by time-of-flight small-angle neutron scattering
Satoshi Koizumi; Yohei Noda; Takumi Inada; Tomoki Maeda; Shiho Yada; Tomokazu Yoshimura; Hiroshi Shimosegawa; Hiroya Fujita; Munehiro Yamada; and Yukako Matsue, A novel surfactant of N–dodecanoyl–N–(2-hydroxyethyl)–β–alanine (coded as C12–EtOH–βAla) was synthesized by modifying the methyl group of N–dodecanoyl–N–methyl–β–alanine (coded as C12–Me–βAla). Amino-acid-type surfactants (C12–EtOH–βAla and C12–Me–βAla) are more healthy and environmentally friendly compared to sodium dodecyl sulfate (SDS). To investigate the microstructures of these new surfactants, we employed a method of time-of-flight small-angle neutron scattering (TOF SANS) at a pulsed neutron source, Tokai Japan (J–PARC). The advances in TOF SANS enable simultaneous multiscale observations without changing the detector positions, which is usually necessary for SANS at the reactor or small-angle X-ray scattering. We performed in situ and real-time observations of microstructures of collapsing shampoo foam covering over a wide range of length scales from 100 to 0.1 nm. After starting an air pump, we obtained time-resolved SANS from smaller wave number, small-angle scattering attributed to (1) a single bimolecular layer with a disk shape, (2) micelles in a bimolecular layer, and (3) incoherent scattering due to the hydrogen atoms of surfactants. The micelle in the foam film was the same size as the micelle found in the solution before foaming. The film thickness (~27 nm) was stable for a long time (<3600 s), and we simultaneously found a Newton black film of 6 nm thickness at a long time limit (~1000 s). The incoherent scattering obtained with different contrasts using protonated and deuterated water was crucial to determining the water content in the foam film, which was about 10~5 wt%., MDPI

Advanced Small-angle Scattering Instrument Available in Tokyo Area II. Time-of-flight Small-Angle Neutron Scattering Developed on iMATERIA Diffractometer at High Intensity Pulsed Neutron Source J-PARC.
Satoshi Koizumi; Yohei Noda; Tomoki Maeda; Takumi Inada; Satoru; Ueda; Takako Fujisawa; Hideki Izunome; Robert A. Robinson; Henrich; Frielingshaus, A method of time-of-flight, small-angle neutron scattering (TOF-SANS) has been developed based on the iMATERIA powder diffractometer at BL20, of the Materials and Life Sciences Facility (MLF) at the high-intensity proton accelerator (J-PARC). A large-area detector for SANS, which is composed of triple-layered 3He tube detectors, has a hole at its center in order to release a direct beam behind and to detect ultra-small-angle scattering. As a result, the pulsed-neutron TOF method enables us to perform multiscale observations covering 0.003 < q (Å−1) < 40 (qmax/qmix = 1.3 × 104) and to determine the static structure factor S(q) and/or form factor P(q) under real-time and in-situ conditions. Our challenge, using unique sample accessories of a super-conducting magnet and polarized neutron, is dynamic nuclear polarization (DNP) for contrast variation, especially for industrial use. To reinforce conventional SANS measurements with powder materials, grazing-incidence small-angle neutron scattering (GISANS) or reflectivity is also available on the iMATERIA instrument., MDPI AG

The Large-Area Detector for Small-Angle Neutron Scattering on iMATERIA at J-PARC
Yohei Noda; Hideki Izunome; Tomoki Maeda; Takumi Inada; Satoru Ueda; Satoshi Koizumi, An area detector with a central hole structure was built up for small-angle neutron scattering (SANS) on the iMATERIA instrument at Japan Proton Accelerator Research Complex (J-PARC). Linear position-sensitive detector tubes filled with 3He gas were arranged in three layers leaving a central hole. As a result of the calibration process, a SANS measurement with wide q-range from 0.007 Å−1 to 4.3 Å−1 was achieved in double-frame operation, supplying neutrons with wavelengths from 1 Å to 10 Å. As a merit of this central hole structure, neutron transmission can be measured simultaneously to reduce experimental time and effort. This is ideal for time-resolved studies, in which the sample transmission can be time-dependent, throughout the whole experiment. Additionally, the data storage system in ‘event mode’ format provides an excellent platform for such time-resolved experiments., MDPI AG

SANS study on the nano-crystalline network structure of elastic physical gels made of syndiotactic polypropylene
Fuyuaki Endo; Naruki Kurokawa; Keishi Tanimoto; Hiroki Iwase; Tomoki Maeda; Atsushi Hotta, The structure-property relationship of an elastic physical gel, obtained by simply quenching syndiotactic polypropylene (sPP)/decahydronaphthalene solution with liquid nitrogen, was investigated based on small-angle neutron scattering (SANS) analysis. The SANS analysis revealed that sPP nanocrystals with a constant radius of 4-5 nm existed in the sPP gels regardless of the sPP concentration, whereas the correlation length of the nanocrystals drastically decreased from ∼130 to ∼20 nm upon increasing the sPP concentration from 2 to 12 wt%. The volume fraction and the number density of the sPP nanocrystals increased monotonously with the increase in the sPP concentration. The rheological properties and the melting behavior of the quenched sPP gels were highly consistent with the number density of the nanocrystals calculated from the SANS analysis, strongly suggesting that the sPP nanocrystals actually worked as crosslinking points by inducing elasticity in the quenched sPP gels., The Royal Society of Chemistry.

Size-tunable MRI-visible nitroxide-based magnetic mixed micelles: preparation, stability, and theranostic application
Nagura, Kota; Bogdanov, Alexey; Chumakova, Natalia; Vorobiev, Andrey; Moronaga, Satori; Imai, Hirohiko; Matsuda, Tetsuya; Noda, Yohei; Maeda, Tomoki; Koizumi, Satoshi; Sakamoto, Koichi; Amano, Tsukuru; Yoshino, Fumi; Kato, Tatsuhisa; Komatsu, Naoki; Tamura, Rui, Metal-free magnetic mixed micelles (mean diameter: 16 nm) composed of biocompatible surfactant Tween 80 and hydrophobic pyrrolidine-N-oxyl radical were prepared by mixing them in phosphate-buffered saline. The magnetic mixed micelles were characterized by dynamic light scattering and small angle neutron scattering measurements. The stability of the micelles is found to depend on the length of alkyl side chain in the nitroxide compounds and degree of unsaturation in the hydrophobic chain in the surfactant. The size of the mixed micelle can be tuned by changing the molar ratio of Tween 80 and nitroxyl radical. In view of theranostic application of the micelle, the cytotoxicity and stability in a physiological environment was investigated; the mixed micelle exhibited no cytotoxicity, high colloidal stability and high resistance towards reduction by large excess ascorbic acid. The in vitro and in vivo magnetic resonance imaging (MRI) revealed sufficient contrast enhancement in the proton longitudinal relaxation time (T 1) weighted images. In addition, hydrophobic fluorophores and an anticancer drug are stably encapsulated in the mixed micelles and showed fluorescence (FL) upon reduction by ascorbic acid and cytotoxicity to cancer cells, respectively. For example, the paclitaxel-loaded mixed micelles efficiently suppressed cancer cell growth. Furthermore, they were found to give higher MRI contrast (higher r 1 value) in vitro than the micelles without paclitaxel. The magnetic mixed micelles presented here are promising theranostic agents in nanomedicine due to their high biocompatibility and high resistivity towards reduction as well as functioning as a drug carrier in therapy and MR or FL imaging probe in diagnosis., IOP Publishing

Uniformly dispersed polymeric nanofiber composites by electrospinning: Poly(vinyl alcohol) nanofibers/polydimethylsiloxane composites
Kentaro Watanabe; Tomoki Maeda; Atsushi Hotta, A method for the fabrication of homogeneous and well-dispersed polymeric nanofiber composites was investigated. Nanofiber fillers can be used to produce polymeric nanocomposites by mixing the fillers to base polymers, eventually enhancing the mechanical property of the matrix polymers. To produce such composites, nanofibers were usually sandwiched by molten matrix polymers at high temperature before molding. The traditional so-called sandwich method, however, was found to produce rather biased and inhomogeneous composites due largely to the solid entanglement of the nanofibers. In this work, unwoven polymer nanofibers were synthesized through electrospinning by controlling the electrostatic repulsion of the nanofibers. We modified the electrospinning apparatus for the direct synthesis of homogenous composites: nanofibers were electrospun and directly ejected from the electrospinning syringe to the matrix polymer solution (not in a solid state), where a regular metal electrode plate was replaced by an optimized metal container containing the base polymer solution. It was found that this new fabrication method could realize homogeneous mixing of the nanofibers that were eventually uniformly dispersed in the polymer solution. Poly(vinyl alcohol) (PVA) was used for nanofibers and polydimethylsiloxane (PDMS) was used for polymer matrix. The field emission scanning electron microscopy (FE-SEM) revealed the homogeneous and well-dispersed PVA nanofibers in the resulting PDMS composites. The composites also presented higher mechanical properties as compared with the composites fabricated by the traditional sandwich method., Elsevier Ltd

Composition-dependent sol-gel transition of amphiphilic blend of PEG with hydrophobic gallamide components
Akihiro Aso; Kazutaka Taki; Tomoki Maeda; Kazunori Toma; Hitoshi Tamiaki; Atsushi Hotta, Two types of poly(ethylene glycol) (PEG)-based amphiphiles were synthesized: a diblock-type amphiphile (PEG1) with a hydrophobic moiety on one terminal of PEG (PEG with the molecular weight of 2000), and a triblock-type amphiphile (PEG2) with hydrophobic moieties on both terminals of PEG. The hydrophobic moiety consisted of hydrophobic C14 alkyl tails covalently linked through a gallamide component. The sol–gel transitions of the aqueous solution of PEG1 and PEG2 were studied. At the PEG amphiphile concentration of 15 wt %, PEG1 gave a clear solution over a wide temperature range from 20 to 80 °C, while PEG2 was partially soluble in water. However, the aqueous blend solution of PEG1 and PEG2 exhibited a hydrogel depending on the blend ratio and temperature. It was considered that the composition of PEG1 and PEG2 governed the sol–gel transition, and that the dynamic moduli could be effectively controlled by changing the mixing ratios of the PEG amphiphiles. © 2017 Wiley Periodicals, Inc.

Thermoplastic polydimethylsiloxane with l-phenylalanine-based hydrogen-bond networks
Shunsuke Tazawa; Atsushi Shimojima; Tomoki Maeda; Atsushi Hotta, Thermoplastic polydimethylsiloxane (PDMS) containing l-phenylalanine was synthesized by the liquid-phase synthesis method with an Fmoc-protected amino acid and by the condensation polymerization. In order to investigate the mechanical and the thermoplastic properties of the PDMS with l-phenylalanine, the tensile testing and the dynamic mechanical analysis (DMA) were conducted. From the results of the tensile testing, it was found that the stress at break of the PDMS with l-phenylalanine nearly became seven times higher than that of the PDMS without l-phenylalanine. The DMA results revealed that the PDMS could maintain its storage modulus for three heating cycles, while the melting temperature was also kept at ∼120 °C. Moreover, the mechanical property was analyzed through two remolding cycles, and it was found that the PDMS could almost maintain its mechanical property after the heat remolding. Finally, it was found that the PDMS also possessed some self-healing property, where the Young's modulus of the cut PDMS could maintain at least 70% of its original Young's modulus after contact and self-healing. © 2017 Wiley Periodicals, Inc.

Mechanically Tough Syndiotactic Polypropylene (sPP) Gels Realized by Fast Quenching Using Liquid Nitrogen
Fuyuaki Endo; Ryusuke Okoshi; Keita Takaesu; Naruki Kurokawa; Hiroki Iwase; Tomoki Maeda; Atsushi Hotta, Physical gels have attracted considerable attention due to the remoldability deriving from the reversible cross-linking points made of noncovalent bonds. In this study, we report a facile method to realize a mechanically tough syndiotactic polypropylene (sPP) gel, one of the physical gels made of semicrystalline polymers. The sPP/decahydronaphthalene gel quenched using liquid nitrogen (GEL LN) presented the fracture stress of over 2 MPa with the fracture strain as high as while the sPP gel prepared at room temperature (GEL 25) presented the fracture stress of only 315 kPa and the fracture strain of similar to 0.3. The fracture stress was found to increase with the increase in the sPP concentration. Furthermore, the structural analyses of the sPP gels revealed that the quenching of the sPP gel suppressed the phase separation, eventually forming homogeneous nanocrystalline cross-linking network structures to produce a mechanically tough sPP gel., AMER CHEMICAL SOC

PEG-based nanocomposite hydrogel: Thermo-responsive sol-gel transition and degradation behavior controlled by the LA/GA ratio of PLGA-PEG-PLGA
Midori Kitagawa; Tomoki Maeda; Atsushi Hotta, The sol-gel transition behavior and the degradation behavior of the nanocomposites consisting of laponite clay nanoparticles and poly(D,L-lactide-co-glycolide)-b-poly(ethylene glycol)-b-poly(D,L-lactide-co-glycolide) (PLGA-PEG-PLGA) triblock copolymers (laponite/PLGA-PEG-PLGA nanocomposites) were studied changing the LA/GA ratios of the PLGA blocks in the PLGA-PEG-PLGA. The thermo-responsive sol-gel transition at the physiological temperature (25–37 °C) was observed using the PLGA-PEG-PLGA with a high PEG/PLGA ratio of ∼0.8 regardless of the LA/GA ratios (LA/GA: 1.1, 4.0, and 8.8). The decomposition rates of the laponite/PLGA-PEG-PLGA nanocomposites at 37 °C were regulated by adjusting the LA/GA ratios (LA/GA: 1.1, 4.0, and 8.8). Specifically, ∼45% of the weight loss was observed after 10 days of the decomposition for the laponite/PLGA-PEG-PLGA nanocomposites with the LA/GA ratio of 1.1, while ∼30% of the weight loss was observed after 10 days of the decomposition for the laponite/PLGA-PEG-PLGA nanocomposites with the LA/GA ratios of 4.0 and 8.8., Elsevier Ltd

In vitro basic fibroblast growth factor (bFGF) delivery using an antithrombogenic 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer coated with a micropatterned diamond-like carbon (DLC) film.
Kenta Bito; Terumitsu Hasebe; Shunto Maegawa; Tomoki Maeda; Tomohiro Matsumoto; Tetsuya Suzuki; Atsushi Hotta, In this study, a newly designed drug-release platform composed of an antithrombogenic 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer was introduced, which was impregnated with basic fibroblast growth factor (bFGF) (bFGF/MPC polymer) to enhance the endothelial cell activation. The platform was also coated with an ultrathin micropatterned diamond-like carbon (DLC) film (DLC/bFGF/MPC polymer) to precisely control the drug release rate and the cell compatibility. The resulting DLC/bFGF/MPC polymer could effectively prolong the bFGF release rate by depositing the micropatterned DLC. The number of adherent platelets on the DLC/bFGF/MPC polymer was significantly lower (about 1/14) than that on a currently used stent made of stainless steel (SUS316L), indicating the enhanced antithrombogenicity in the DLC/bFGF/MPC polymer. The proliferation of endothelial cells on the DLC/bFGF/MPC polymer and the DLC/MPC polymer (without bFGF) were also examined. It was found that the optical density of HUVEC on the DLC/bFGF/MPC polymer determined by WST-8 assay was higher by 25%than that on the DLC/MPC polymer (without bFGF) measured after 72 h of incubation. Our results suggest that the released bFGF that contributes to the expression of other growth factors results in the early proliferation of the HUVEC on the DLC/bFGF/MPC polymer. © 2017 Wiley Periodicals, Inc.

PEG-based nanocomposite hydrogel: Thermoresponsive sol-gel transition controlled by PLGA-PEG-PLGA molecular weight and solute concentration
Makoto Miyazaki; Tomoki Maeda; Kenji Hirashima; Naruki Kurokawa; Koji Nagahama; Atsushi Hotta, A PEG-based copolymer with a high PEG ratio was synthesized and the sol-gel transition temperature (T-gel) around the physiological temperature (25 degrees C-37 degrees C) was achieved. Specifically, we synthesized a triblock PEG copolymer of poly ((D),(L)-lactide-co-glycolide)-b-poly (ethylene glycol)-b-poly ((D),(L-)lactide-co-glycolide) (PLGA-PEG-PLGA) with different molecular weights and a high PEG/PLGA ratio of 0.80. By adding synthetic clay (laponite) to an aqueous solution of the PEG-based copolymer, it was found that the discriminating concentration combinations of the laponite (from 0.75 to 1.5 wt%) and the PLGA-PEG-PLGA (from 2.0 to 5.0 wt%) could effectively regulate the T-gel to fall between 25 degrees C and 37 degrees C (physiological temperature), simultaneously controlling the storage and the loss moduli of the specimens studied by the dynamic mechanical analyses (DMA). The structural analyses were also performed by the cryo-TEM and the high-resolution small angle X-ray scattering (SAXS) measurements at SPring-8, Japan. (C) 2017 Elsevier Ltd.

Syndiotactic polypropylene nanofibers obtained from solution electrospinning process at ambient temperature
Tomoki Maeda; Keita Takaesu; and Atsushi Hotta, 筆頭著者, Fabrication of semicrystalline syndiotactic polypropylene (sPP) nanofibers by solution electrospinning was studied. It was found that sPP nanofibers with an average diameter of 230 nm were successfully fabricated via solution electrospinning with methylcyclohexane as solvent at room temperature (25 degrees C). The obtained diameter was significantly thinner than the minimum diameter of 350 nm of PP fibers that were reported previously. It was also found that increasing viscosity of the sPP solution, which was customarily a useful way of fabricating noncrystalline thin fibers, was found ineffectual in producing thinner semicrystalline sPP fibers in our experiments. In fact, a careful selection of solvent by considering the evaporation rate and the specific viscosity could effectively lead to the fabrication of thinner sPP fibers by imposing proper elongation and preventing the sPP solution from gelation. The results could be applied to other semicrystalline polyolefins with similar gelation characteristics analogous to sPP to produce thinner nanofibers.

Biodegradability, reprocessability, and mechanical properties of polybutylene succinate (PBS) photografted by hydrophilic or hydrophobic membranes
Sawako Mizuno; Tomoki Maeda; Chiharu Kanemura; Atsushi Hotta, The biodegradability and the reprocessability of surface-modified polybutylene succinate (PBS) covalently grafted by hydrophilic or hydrophobic membrane were investigated. The original ungrafted PBS already possesses desirable mechanical and thermal properties, which are very close to those of widely used polyolefins such as polyethylene and polypropylene, but the intrinsic inflexible biodegradability of PBS is still limiting its practical use. Controlling the biodegradability and the reprocessability of PBS, therefore, is necessary to extend the usage of PBS. In this research, the surface of PBS was modified by the photografting polymerization of hydrophilic acrylic acid (AA) and hydrophobic styrene (St) monomers. The surface of PBS became more hydrophilic by increasing the reaction time of the photografting polymerization of AA (or hydrophobic when St was used). Additionally, to estimate the reprocessability of the photografted PBS, the surface-modified PBS was carefully remolded and hence the grafted-membrane was evenly dispersed in the reprocessed and recycled PBS. The structural and mechanical analyses of the modified PBS revealed that the biodegradability and the reprocessability of PBS were effectively controlled by the surface modification via the photografting polymerization and the successive internal dispersion of the grafted membrane. These experimental results may highly provide a new possibility of the extensive use of PBS as an alternative material for polyolefins. (c) 2015 Elsevier Ltd. All rights reserved., ELSEVIER SCI LTD

Poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) nanofibers coated with micro-patterned diamond-like carbon (DLC) for the controlled drug release
Kenta Bito; Tomoki Maeda; Katsuya Hagiwara; Soki Yoshida; Terumitsu Hasebe; Atsushi Hotta, © Japanese Society of Biorheology 2015. Attaining high hemocompatibility and promoting endothelialization are two major keys to solve the endoleak problems observed in existing stent-grafts. For the satisfactory long-term use of the stent-grafts, blocking the endoleak symptom is highly essential. This paper deals with the fabrication of electrospun nanofibers made of antithrombogenic poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) containing drug that can sustain the endothelial activity of the MPC nanofibers. Moreover, the drug release was controlled by micro-patterned diamond-like carbon (DLC) coated on the MPC nanofibers. It was found that MPC nanofibers retained excellent hemocompatibility and that the micro-patterned DLC efficiently controlled the drug-release rate of MPC fibers.

) on the sol-gel transition behaviors, especially the gelation speed and the gel characteristics of the designed PA (C16-W3K) hydrogels in aqueous solution were discussed. It was found that the original solution state before rheological testing was independent of the salt concentration, which was confirmed by observing the self-assembly structures and the peptide secondary structures of PA through transmission electron microscopy (TEM) and circular dichroism spectroscopy (CD). The PA solutions with different salt concentrations, however, presented a profound difference in the gelation speed and the gel characteristics: the solution exhibited higher gelation speeds and higher mechanical properties at higher salt concentrations. Concurrently, the density, the length of wormlike micelles, and the conformational ratio of β-sheets to α-helices in the equilibrium PA solutions all increased with the increase in the salt concentrations., American Chemical Society

These nanofibers were investigated as drug-delivery vehicles for suppressing the acute thrombogenicity of vascular grafts to lower the risk of coronary artery disease by improving the graft patency rate
the graft patency rate is the percentage of patients who do not have any blockage in a graft after a stent-graft treatment. We varied the MPC concentrations in ethanol from 1 to 10 wt % to fabricate electrospun MPC fibers. Scanning electron microscopy images revealed that when the MPC concentration was lower than 5 wt %, beads instead of fibers were formed. When the MPC concentration was increased (>
5 wt %), uniform fibers were produced with average fiber diameters of about 160 nm (5 wt %), 640 nm (7.5 wt %), and 1270 nm (10 wt %). In vitro drug-release tests showed that a higher amount of drugs was diffused from MPC fibers with small diameters
this indicated a faster drug-release rate for the thinner MPC fibers. Diameter-controlled MPC fibers could be used as a new vascular graft materials. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40606. Copyright © 2014 Wiley Periodicals, Inc., John Wiley and Sons Inc.
