In a previous work [C. E. Starrett and D. Saumon, Phys. Rev. E 87, 013104 (2013)] a model for the calculation of electronic and ionic structures of warm and hot dense matter was described and validated. In that model the electronic structure of one atom in a plasma is determined using a density-functional-theory-based…
ABSTRACT To improve the crystallization ability of poly(lactic acid) (PLA), a novel nucleating agent with a benzoyl hydrazine compound was used in this study. The crystallization behaviors of PLA/talc and PLA/bibenzoylhydrazinepropane (BBP) with or without poly(ethylene glycol) (PEG) were investigated with differentia…
A superparamagnetic nanoferrite (SPNF) with high magnetic moment, AC magnetically induced heating (AC-heating) capacity, and good biocompatibility is the most vital part of magnetic fluid hyperthermia for utilizing it in the clinics. Herein, we precisely tune magnetic properties and AC-heating characteristics of MgxMn…
Phosphomonoester hydrolases (phosphatases; EC 3.1.3.) often exhibit extremely relaxed substrate specificity which limits their application to substrate-selective biotransformations. In search of a phosphatase catalyst specific for hydrolyzing α-d-glucose 1-phosphate (αGlc 1-P), we selected haloacid dehalogenase-like p…
A term project was introduced in teaching advanced spectroscopy and notions of nanotechnology to chemistry students at the graduate level (M.Sc. and Ph.D.). This project could also be suited for an honor’s thesis at the undergraduate level. Students were assigned a unique combination of nanoparticle synthesis (13 nm A…
A critical challenge in the fabrication of chalcogenide-glass infrared optical fibers is the need for first producing large volumes of high-purity glass-a formidable task, particularly in the case of multicomponent glasses. We describe here a procedure based on multimaterial coextrusion of a hybrid glass-polymer prefo…
In this paper we present a method to produce superhydrophobic polymeric coatings by combining the rapid expansion of supercritical solutions (RESS) with electrostatic deposition (ED). A copolymer, poly(vinyl acetate)–poly(vinyl pivalate) was dissolved in a mixture of supercritical carbon dioxide and acetone and spraye…
We study the thermopower of a disordered nanowire in the field effect transistor configuration. After a first paper devoted to the elastic coherent regime (Bosisio, Fleury and Pichard 2014 New J. Phys. 16 035004 ), we consider here the inelastic activated regime taking place at higher temperatures. In the case where t…
The magnetization behaviour of the ferromagnetic shape memory Heusler Ni2MnGa alloy under applied magnetic fields is studied using first-principles and Monte Carlo (MC) calculations. Calculations were carried out for single-crystal and polycrystalline structures with magnetic domains. In the multi-domain approach, the…
In this work, we report the condensation and stabilization of water vapors into water-repellent, methyl-functionalized, mesoporous, silica-based films at room temperature and atmospheric pressure using a soft alcohol-assisted method. The capillary pore fillings due to water adsorption were ensured by a fine control of…
This review focuses on the various single crystal growth techniques applied to the new class of high temperature superconductors—iron-based layered pnictides, such as the parent compounds A Fe 2 As 2 ( A = Ba, Sr, Ca) (122), hole-doped A 1 − x K x Fe 2 As 2 , electron/hole-doped A Fe 2 − x M x As 2 ( M = Co, Ni, Mn, C…
Energetic heavy ions passing through polymer foils cause modifications of properties, first of all structural changes. In order to evaluate ion beam modification of fluoropolymers, a comparison of polyvinylidene fluoride (PVDF), ethylene-tetrafluoroethylene (ETFE), tetrafluoroethylene-per-fluoromethoxyethylene (PFA),…
We demonstrate control over the morphology and shape of microparticles. Two different types of microparticles (core–shell or acorn shaped) were produced by the varying the blend ratio of two immiscible biodegradable polymers in a tube-type microfluidic device. Subsequent use of selective solvent extraction resulted in…
Amphiphilic pentablock copolymers of poly (trifluoroethyl methacrylate)-b-poly (methyl methacrylate)-b-poly (ethylene glycol)-b-poly (methyl methacrylate)-b-poly (trifluoroethyl methacrylate) (PTFEMA-b-PMMA-b-PEG-b-PMMA-b-PTFEMA) with three different block ratios as well as molecular weights were used to fabricate hon…
The 9-mesityl-10-methylacidinium cation (Acr + -Mes) was incorporated into Na + -exchanged mesoporous aluminosilicate (AlMCM-41) by cation exchange. Incorporation of Acr + -Mes into AlMCM-41 has made the lifetime of the electron-transfer (ET) state (Acr • -Mes •+ ) produced upon photoexcitation of Acr + -Mes extremely…
Macromolecular crowding can influence polymer shapes, which is important for understanding the thermodynamic stability of polymer solutions and the structure and function of biopolymers (proteins, RNA, DNA) under confinement. We explore the influence of nanoparticle crowding on polymer shapes via Monte Carlo simulatio…
Zero-index-metamaterials (ZIM) have drawn much attention due to their intriguing properties and novel applications. Particularly, in a parallel plated ZIM waveguide system with defects, total reflection or transmission of wave can be achieved by adjusting the properties of defects. This effect has been explored extens…
We quantify the rate and efficiency of picosecond electron transfer (ET) from PbS nanocrystals, grown by successive ionic layer adsorption and reaction (SILAR), into a mesoporous SnO2 support. Successive SILAR deposition steps allow for stoichiometry- and size-variation of the QDs, characterized using transmission ele…
Stimuli-responsive self-assembly is playing an increasingly important role in emerging applications, ranging from smart materials to biosensors. However, obtaining essential information for further development, such as molecular arrangement and interaction, is still experimentally challenging. A molecular-level unders…
A flux-free solution to the growth of large and composition homogeneous superconducting FeSe crystal is reported for the first time, which is based on the traveling-solvent floating-zone technique. The size of the crystal samples prepared by this approach is up to 15 × 6 × 2 mm 3 , being far bigger than previously rep…
