Abstract We propose a theoretical framework for dealing with a transient polymer network undergoing small deformations, based on the rate of breaking and reforming of network cross-links and the evolving elastic reference state. In this framework, the characteristics of the deformed transient network at microscopic an…
We report how the presence of electron-beam-induced sulfur vacancies affects first-order Raman modes and correlate the effects with the evolution of the in situ transmission-electron microscopy two-terminal conductivity of monolayer MoS2 under electron irradiation. We observe a red-shift in the E' Raman peak and a les…
PURPOSE: The B0 and B1+ maps required for calculation of the radiofrequency (RF) pulse of parallel transmission (pTx) are obtained in calibration scans; however, they may be affected by respiratory motion. We aimed to compare the reproducibility of B0 and B1+ maps and gradient echo (GRE) images of the brain scanned wi…
OBJECTIVE: To investigate the effect of chitooligosaccharide (COS) on hepatic triglyceride (TG) metabolism and related mechanisms. METHODS: The LO2 cells treated by 1 mmol/L fatty acid were used as model group, the cells treated by 1 mmol/L fatty acid and 0.5 mg/ml COS were used as COS group, and the untreated cells w…
Development of scaffold is essential for promoting and supporting healing process. This study aims to establish a decellularized rabbit aorta for clinical vascular tissue engineering therapy. We successfully prepared decellularized small-diameter aortic scaffolds and investigated several properties of this engineered…

Ethylbenzene ( EB ) and p ‐xylene ( PX ) are important chemicals for the production of industrial materials; accordingly, their efficient separation is desired, even though the difference in their boiling points is very small. This paper describes the efforts toward the identification of high‐performance extractive ag…
In this study, the construction of macroscopic segregated CNTs network is achieved by a simple melt coating method. In the process, poly( l ‐lactic acid) (PLA) is chosen as the polymer matrix and poly(propylene carbonate) (PPC) is chosen as a carrier polymer for CNTs and an interfacial compatilizer for segregated PLA…
Prescription and/or over the counter medications when taken together with certain foods or herbal substances, leads to either increase or decrease a drug’s therapeutic out comes or adverse effects. It has been reported that a number of plant materials alter some pharmacokinetic parameters of chloroquine when administe…
Recently published experimental work on evolution-in-materio applied to nanoscale materials shows promising results for future reconfigurable devices. These experiments were performed on disordered nano-particle networks that have no predefined design. The material has been treated as a blackbox, and genetic algorithm…
Rhodamine is one of the most widely used fluorescent dyes. Here, a new synthetic pathway to the popular dyes is reported and the effect of adding four methoxy groups to the molecular structure is investigated. Tetramethoxy-aminorhodamine (TMARh) is found to show superior pH switching compared to the rhodamine without…
Amphibian species such as tree frogs, torrent frogs, and arboreal salamanders possessing adhesive organs on their feet show superior wet adhesion abilities. In recent years, many research efforts have been carried out to understand the wet adhesion mechanisms. The surface tension (namely capillary force) from a thin f…
The optical properties of Yb-doped LaB6 have been investigated by first-principles calculations within the framework of density functional theory. The results show that the Yb [Formula: see text] states at near Fermi surface affect their optical properties and the Yb-doping leads to a reduction of the plasmon energy o…
Polymer blend based on polyvinylidene fluoride (PVDF)/polymethyl methacrylate (PMMA) and the blend incorporated with low content (≤0.08) of graphene (GN) oxide were prepared. The characteristic bands for PVDF and PMMA were detected in Raman and IR spectroscopy. There are shifts in Raman and IR spectra due to interacti…

Abstract Graphitic carbon nitride (g‐C3N4) coupled with Bi2WO6 is a promising Type II heterojunction, but it is still difficult to obtain uniform nanocomposites of these materials with the present assembly methods. Here we employ g‐C3N4 nanosheets saturated with Bi3+ ions to provide numerous and widespread nucleation…
A series of novel, highly phosphorescent cyclometalated iridium(III) complexes of type [(X 2 C^N) 2 Ir(Q 2 bpy)] + PF 6 – (where X 2 C^N is 2-phenylpyridine or 2-(2,4-difluorophenyl)pyridine anion and Q 2 bpy are 4,4′-bifunctionalized 2,2′-bipyridines) is presented. The complexes were fully characterized by means of N…
Acrylic acid is one of the most desired products from bioglycerol. In this work, we demonstrated that Keggin-type heteropoly compounds (HPCs) act as efficient bifunctional catalysts for the one-step conversion of glycerol to acrylic acid in gas phase. This is the first example of HPCs as catalysts for selective conver…
Solution-processable organic photovoltaics (OPV) has emerged as a promising clean energy-generating technology due to its potential for low-cost manufacturing with a high power/weight ratio. The state-of-the-art OPV devices are processed by hazardous halogenated solvents. Fabricating high-efficiency OPV devices using…
A novel aluminium-doped nickel copper ferrite nanomaterial prepared via the sol-gel method is considered as potential electrode material for supercapacitors. The morphology, chemical composition and crystallinity have been investigated by scanning electron microscope, energy dispersive spectroscopy and Xray diffractio…
