Organic materials that produce coherent lattice phonon excitations in response to external stimuli may provide next generation solutions in a wide range of applications. However, for these materials to lead to functional devices in technology, a full understanding of the possible driving forces of coherent lattice pho…
The high cost and poor atom utilization efficiency of noble metal catalysts have limited their industrial applications. Herein, we designed CeO 2 -supported single Au(III) ion catalysts with ultra-low gold loading that can enhance the utilization efficiency of gold atoms and bridge the gap between homogeneous and hete…
A novel Fe-Co binary hollow fiber was synthesized by electroless plating using hydrolyzed polyester fiber and its anisotropy characteristic was investigated for electromagnetic wave absorbing materials. The hollow fibers in parallel with magnetic field show higher saturated magnetization of 202 emu/g at the applied ma…
Synthesis of new cyclotetrasiloxane scaffolds containing peripherally functionalized 3-pyridyl moieties, [MeSiO(CH═CH(3)Py)]4 (L(1)) and [MeSiO(CH2CH2(3)Py)]4 (L(2)), and their reactivity studies with certain d(10) metal ions are reported. The ligand L(1) is obtained by the Heck-coupling reaction of tetramethyl tetrav…
Experiments have indicated that bulky ligands are required for efficient H2 activation by Pt-Sn complexes. Herein, we unravel the mechanisms for a Pt-Sn complex, Pt(Sn(t)Bu3)2(CN(t)Bu)2 (1a), catalyzed reversible H2 activation. Among a number of Pt-Sn catalysts used to model H2 activation and H2/D2 exchange reactions,…
This paper discuss a series of Ho³⁺/Yb³⁺ codoped silicate glasses prepared by the melting method. 2 μm emissions of the samples are observed under the pump of 980 nm LD. The Judd-Ofelt parameters (Ω(λ)) and radiative properties are calculated and analyzed; the spontaneous transition probability can reach 78.71 s⁻¹. Fr…
The dissolution of sugarcane bagasse cellulose (SBC) in zinc chloride solution was studied at elevated temperatures. Based on single factor experiments, the effects of zinc chloride mass fraction, dissolution time, temperature, and bagasse cellulose mass fraction were investigated by an orthogonal experiment, and the…
ABSTRACT This article reports an optimal designing of thermoplastic polyurethane (TPU) nanocomposite formulation, particularly targeting aerostat envelope for enhanced weathering and gas barrier properties. The synergistic effect of conventional UV protective additive with advanced nano materials (i.e. nanoclay and gr…
In contrast to its bulk crystal, the FeSe thin film or layer exhibits better superconductivity performance, which recently attracted much interest in its fundamental research as well as in potential applications around the world. In the present work, tuning superconductivity in FeSe thin films was achieved by magnesiu…
ABSTRACT Ultrafiltration (UF) is a size selective pressure‐driven membrane separation process increasingly required for high efficient water treatment and suspended solids removal in many industrial applications. This study examined the morphology of as‐prepared cellulose nanofibers and then utilized the nanofibers di…
ABSTRACT Flame‐retardant polyamide 66 (PA66) was prepared by the polymerization between PA66 prepolymer and N ‐benzoic acid (ethyl‐ N ‐benzoic acid formamide) phosphamide (NENP). Compared with the pure PA66, the flame‐retardant PA66 exhibited better thermal stability, as indicated by thermogravimetric analysis results…
In this study, a new method of fabricating conductive NR nanocomposites was proposed. Graphene oxide (GO) was obtained through oxidization and exfoliation of graphite and was employed as a reinforcing nanofiller for natural rubber (NR). GO/NR nanocomposites with different concentrations of GO were prepared by a latex…
Observing structural integrity of nanoparticles is essential in bionanotechnology but not always straightforward to measure in situ and in real-time. Fluorescent labels used for tracking intrinsically nonfluorescent nanomaterials generally do not allow simultaneous observation of integrity. Consequently, structural ch…
Using extended time series scanning transmission electron microscopy, we investigate structural fluctuations at an incommensurate grain boundary in Au. Atomic-resolution imaging reveals the coalescence of two interfacial steps, or disconnections, of different height via coordinated motion of atoms along close-packed d…
Gold (Au) nanoparticles are promising photothermal agents with the potential of clinical translation. However, the safety concerns of Au photothermal agents including the potential toxic compositions such as silver and copper elements in their structures and the relative large size-caused retention and accumulation in…
The adsorption ability of natural clay minerals and zeolites is a structurally caused distinguished feature, which determines their physical–chemical properties and almost each area of application. The type of surface active sites responsible for adsorption behavior differs for various structural types of aluminosilic…
To reduce power consumption by light shutters, bistable light shutters using cholesteric liquid crystal have been proposed. However, these bistable light shutters, which utilize the scattering of the incident light, are switchable only between transparent and translucent states. In this work, we successfully demonstra…
Understanding nonequilibrium glassy dynamics is of great scientific and technological importance. However, prediction of the temperature, thermal history, and composition dependence of nonequilibrium viscosity is challenging due to the noncrystalline and nonergodic nature of the glassy state. Here, we show that the no…
The best alternative to conventional pesticides is nanopesticide. Severe pollution is caused due to the rapid degradation and uncontrolled, unconstrained utilization of conventional pesticides. Nanopesticides can provide better penetration through the plants and control different diseases. Nanoformulation of pesticide…
With our recently developed deformation device, the in situ tensile tests of single crystal molybdenum nanowires with various size and aspect ratio were conducted inside a transmission electron microscope (TEM). We report an unusual ambient temperature (close to room temperature) super-plastic elongation above 127% on…
