Starting from the recently proposed energy-based deviational formulation for solving the Boltzmann equation [J.-P. Péraud and N. G. Hadjiconstantinou, Phys. Rev. B 84, 205331 (2011)], which provides significant computational speedup compared to standard Monte Carlo methods for small deviations from equilibrium, we sho…
SrTiO 3 crystalline nanoparticles were prepared using the microwave-assisted hydrothermal method at 140 °C with synthesis times varying from 4 to 160 min. Sample characterization showed that the method is effective in obtaining nanoparticles in a relatively short time, which have the highest photoluminescence emission…
The reaction of ((Ar)L)Co(py) with (t)BuN(3) afforded the isolable three-coordinate Co-imido complex ((Ar)L)Co(N(t)Bu), which is paramagnetic at room temperature. Variable-temperature (VT) (1)H NMR spectroscopy, VT crystallography, and magnetic susceptibility measurements revealed that ((Ar)L)Co(N(t)Bu) undergoes a th…
In the present study, the two grafting techniques grafting-from - by activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) - and grafting-to - by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) - were systematically compared, employing cellulose as a substrate. In order t…
This highly readable, popular textbook for upper undergraduates and graduates comprehensively covers the fundamentals of crystallography and symmetry, applying these concepts to a large range of materials. New to this edition are more streamlined coverage of crystallography, additional coverage of magnetic point group…
Poly(lactic acid) (PLA) is known to be a useful material in substituting the conventional petroleum-based polymer used in packaging, due to its biodegradability and high mechanical strength. Despite the excellent properties of PLA, low flexibility has limited the application of this material. Thus, epoxidized palm ole…
Twenty years ago Poole et al. suggested that the anomalous properties of supercooled water may be caused by a critical point that terminates a line of liquid-liquid separation of lower-density and higher-density water. Here we present a thermodynamic model based on this hypothesis, which describes all available experi…
Using first-principles calculations within density functional theory, we investigate the intrinsic spin Hall effect in monolayers of group-VI transition-metal dichalcogenides $M{X}_{2}$ ($M=\mathrm{Mo},\phantom{\rule{0.16em}{0ex}}\phantom{\rule{0.16em}{0ex}}\mathrm{W}$ and $X=\mathrm{S},\phantom{\rule{0.16em}{0ex}}\ph…
We demonstrate the design, characterization, and interference-theory interpretation of a terahertz triple-band metamaterial absorber (MA). The experiments show that the fabricated MA has three distinctive absorption peaks at 0.5, 1.03, and 1.71 THz with absorption rates of 96.4%, 96.3%, and 96.7%, respectively. We use…
Real-time monitoring of cell apoptosis could provide valuable insights into early detection of therapy efficiency and evaluation of disease progression. In this work, we designed and synthesized a new live-cell-permeable, fluorescent light-up probe for real-time cell apoptosis imaging. The probe is comprised of a hydr…
The structures, the phase diagrams, and the appearance of a neutron resonance signaling an unconventional superconducting state provide phenomenological evidence relating the cuprates, the Fe-pnictides and chalcogenides as well as some heavy-fermion and actinide materials. Single-band and multiband Hubbard models have…
X-ray crystallography is a technique used to determine the atomic-detail structure of a biological macromolecule. The method relies on the ability to generate a three-dimensional crystal of a highly purified protein or nucleic acid for diffraction by X-rays. The extent of scattering of X-rays by the crystal determines…
We report the first observation of spin-flop-induced sharp positive magnetoresistance as large as 100% and nonvolatile magnetoresistive memory in a π-d hybrid molecular conductor, (DIETSe)(2)FeCl(4) [DIETSe = diiode(ethylenedithio)tetraselenafulvalene]. The unprecedented magnetotransport phenomena originate from the c…
Silk fibers are well known for their mechanical properties such as strength and toughness and are lightweight, making them an interesting material for a variety of applications. Silk mechanics mainly rely on the secondary structure of the underlying proteins. Lacewing egg stalk silk proteins obtain a cross-β structure…
Polyhydroxyalkanoate (PHA) synthase from Aeromonas caviae FA440 (PhaC(Ac), BAA21815) is one of the most valuable PHA synthase, because of its function to synthesize a practical bioplastic, poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] [P(3HB-co-3HHx)]. However, biochemical activity and active intermediates of…
We report electroluminescence from ion-gel gated, field-effect transistors based on the conjugated polymer, poly(9,9′-dioctylfluorene-co-benzothiadiazole) gated by an 1-ethyl-3-methylimidazoliumbis (trifluoromethylsulfonyl) imide/poly (styrene-block-ethylene oxide-block-styrene) ion gel, and investigate the mechanism…
The aim of this study was to fabricate nanofibrous scaffolds based on blends of a hydroxyl functionalized polyester (poly(hydroxymethylglycolide-co-ε-caprolactone), pHMGCL) and poly(ε-caprolactone) (PCL), loaded with bovine serum albumin (BSA) as a protein stabilizer and vascular endothelial growth factor (VEGF) as a…
Electrospinning provides a versatile method for generating fibrous materials from a large variety of substances, including polymers, composites, proteins, and nano/microcolloids. In particular, the incorporation of nano/microparticles with polymeric materials is beneficial to many of electrospun fibers with multiple f…
Semiconductor quantum dots (Qdots) are a promising new technology with benefits in the areas of medical diagnostics and therapeutics. Qdots generally consist of a semiconductor core, capping shell, and surface coating. The semiconductor core of Qdots is often composed of group II and VI metals (e.g., Cd, Se, Te, Hg) t…
We investigate the effect of mechanical strain on graphene synthesized by chemical vapor deposition (CVD) transferred onto flexible polymer substrates by observing the change in the Raman spectrum and then compare this to the behavior of exfoliated graphene. Previous studies into the effect of strain on graphene have…
