Although monolayer black phosphorus (BP), or phosphorene, has been successfully exfoliated and its optical properties have been explored, most of the electrical performance of the devices is demonstrated on few-layer phosphorene and ultrathin BP films. In this paper, we study the channel length scaling of ultrathin BP…
Binary transition metal oxides (BTMOs) possess higher reversible capacity, better structural stability and electronic conductivity, and have been widely studied to be novel electrode materials for supercapacitors.
Nanomedicines (NMs) offer new solutions for cancer diagnosis and therapy. However, extension of progression-free interval and overall survival time achieved by Food and Drug Administration-approved NMs remain modest. To develop next generation NMs to achieve superior anticancer activities, it is crucial to investigate…
Oil spills and industrial organic pollutants have induced severe water pollution and threatened every species in the ecological system. To deal with oily water, special wettability stimulated materials have been developed over the past decade to separate oil-and-water mixtures. Basically, synergy between the surface c…
SUMMARY In recent years, remarkable advancement of new power semiconductor devices, such as SiC and GaN, enables the increase of switching frequency of power converters, and hence the volume of passive components, such as ac filters and transformers, can be reduced. However, temperature rise caused by the inductor los…
Using nonresonant Fe $K\ensuremath{\beta}$ x-ray emission spectroscopy, we reveal that Sr substitution into ${\mathrm{CaFe}}_{2}{\mathrm{As}}_{2}$ decouples the Fe moment from the volume collapse transition, yielding a collapsed-tetragonal, paramagnetic normal state out of which superconductivity develops. X-ray diffr…
Polylactide (PLA) is a commercially produced potentially sustainable plastic that holds promise to replace petroleum‐sourced materials. Unfortunately, the brittle nature of PLA limits its current utility to disposable packaging. Melt blends of PLA and a rubbery material can rubber toughen the plastic, but often requir…
A scaffold, which can provide mechanical support for tissue regeneration and simultaneously release functionally active biomolecules are highly desirable for tissue engineering applications. Herein, we report the fabrication of a fibrous mesh of polycaprolactone (PCL) incorporating PCL-pluronic (F127) microvesicles th…
Two types of bimetallic nanoparticle are constructed on soft substrates via a laser-induced transfer technique. One particle is a physical mixture with distinct gold and silver nanoparticles, while the other is a gold-silver alloy nanoparticle. Different hybrid plasmon responses can be achieved by these nanoparticles,…
We report a novel method for stable doping of carbon nanotubes (CNT) based on methods of molecular self assembly. A conformal growth of a self-assembled monolayer of fluoroalkyl trichloro-silane (FTS) at CNT surfaces results in a strong increase of the sheet conductivity of CNT electrodes by 60–300%, depending on the…
We calculate the effect on phonon transport of substrate-induced bends in graphene. We consider bending induced by an abrupt kink in the substrate, and provide results for different step-heights and substrate interaction strengths. We find that individual substrate steps reduce thermal conductance in the range between…
The nanocomposites of polyamide 6/polystyrene (PA6/PS) with different contents of organic montmorillonite (OMMT) have been obtained by melt blending. The combustion behaviors, morphology of char residues, and thermal stability of nanocomposites have been characterized by cone calorimeter tests (CCT), electron probe mi…
ABSTRACT We fabricated novel superhydrophobic coatings based on SiO 2 nanoparticles combined with NH 2 ‐terminated silicone (SN 2 ) or SN 2 ‐modified polyurethane (SN 2 ‐prePU) by alternately spin‐coating them onto glass slides. The final fabricated surface contained SN 2 /SiO 2 or SN 2 ‐prePU/SiO 2 bilayers. The cond…
Making use of homogenization techniques, core-shell particle nanocomposites have been considered to estimate the efficiency of the effective permittivity nulling and enhanced absorption in terms of bandwidth. Core-shell metallodielectric spheres are shown to hold promise as building blocks for the design of metamateri…
Orthoferrite perovskite LaFeO3 has been of great interest with its versatility for potential applications in electromagnetic, catalytic, and sensing applications. Nanowires have shown great potential as active building blocks for assembling a variety of nanoscale devices, nevertheless far less is known about the chara…
Poly(oligoethyleneglycol methacrylate) (POEGMA) covalently attached to TiO2 nanoparticles (NPs) were synthesized by the surface-initiated ARGET ATRP. The growth of polymer chains from the surface of ATRP-initiator functionalized nanoparticles was achieved under mild condition by using copper (II) as a catalyst and zer…
THE REVIEW OF FOUR EXPERIMENTAL METHODS: X-ray diffraction, Raman spectroscopy, electron paramagnetic resonance and four-point electrical conductivity measurements is presented to characterize carbon nanoparticles. Two types of carbon nanoparticle systems are discussed: one comprising the powder of individual carbon n…
<div class="section abstract"><div class="htmlview paragraph">Internal Diesel Injector Deposits (IDIDs) have been known for some time. With the latest powertrains becoming ever more sophisticated and reliant on efficient fuel delivery, the necessity for a continued focus on limiting their formation remains…
This study focuses on the effect of long-term exposure to high-temperature atmosphere on mechanical properties of carbon fiber reinforced plastic (CFRP) laminate with polycyanate resin system. Transversely oriented unidirectional laminate of carbon fiber/polycyanate (T700SC/FSD-M-08178) CFRP was employed on isothermal…
The dynamical phase transition mechanism of $({\mathrm{Na}}_{1/2}{\mathrm{Bi}}_{1/2}){\mathrm{TiO}}_{3}$ (NBT) was studied using inelastic neutron scattering. Softening was observed of multiple phonon modes in the phase transition sequence of NBT. As usual, the softening of the zone center transverse optical modes ${\…
