Adipose tissue-derived mesenchymal stem cells (ASC) are of great interest as a cellular therapeutic agent for regenerative and immunomodulatory purposes. The function of ASC adapts to environmental conditions, such as oxygen tension. Oxygen levels within tissues are typically much lower than under standard culture con…
In this paper, we introduce and investigate each of the following subclasses:
The merits of ultrasound contrast agents (UCAs) were already known in the 1960s. It was, however, not until the 1990s that UCAs were clinically approved and marketed. In these years, it was realized that the UCAs are not just efficient ultrasound scatterers, but that their main constituent, the coated gas microbubble,…
Anatase TiO2 is considered as one of the promising anode materials for lithium ion batteries (LIBs) because of its nontoxicity, safety, and excellent capacity retention. However, the poor rate capability of TiO2 electrodes, caused by the low electrical conductivity and lithium diffusion coefficient, strongly hinders i…
Mixed metal oxides have been attracting more and more attention recently because of their advantages and superiorities, which can improve the electrochemical performance of single metal oxides. These advantages include structural stability, good electronic conductivity, and reversible capacity. In this work, uniform y…
A new electrochemical sensor for 4-nitrophenol (4-NP) detection based on the reduced graphene oxide (RGO) and Au nanoparticle composite was developed. The RGO film was first electrodeposited onto a glassy carbon electrode (GCE). Then Au nanoparticles (AuNPs) were electrochemically deposited onto the RGO film. The morp…
As the starting point for a comprehensive theoretical investigation of the linear and nonlinear optical susceptibilities, we have used our experimental crystallographic data for Ag0.5Pb1.75GeS3Se (Ag2Pb7Ge4S12Se4) reported. The experimental crystallographic positions were optimized by minimizing the forces acting on e…
In this work, tin selenide thin films (SnSex) were grown on soda lime glass substrates by selenization of dc magnetron sputtered Sn metallic precursors. Selenization was performed at maximum temperatures in the range 300 °C to 570 °C. The thickness and the composition of the films were analysed using step profilometry…
Mechanically responsive polymers harness mechanical energy to facilitate unique chemical transformations and bestow materials with force sensing (e.g., mechanochromism) or self-healing capabilities. A variety of solution- and solid-state techniques, covering a spectrum of forces and strain rates, can be used to activa…
An innovative auxetic-cored sandwich panel (AXP) is proposed. Its perforation resistant performance under high-velocity projectile impact was numerically analyzed using the validated finite element simulation techniques and compared with that of the aluminum foam-cored sandwich panel (AFP) of identical dimensions and…
We report the emission wavelength tunability of an excited state intramolecular proton transfer (ESIPT) fluorophore, 2,4-dibenzothiazolylphenol (2,4-DBTP), and its application to white light generation. In a nonpolar solvent, yellow fluorescent 2,4-DBTP had a maximum emission around 560 nm, but did not absorb light in…
A highly selective fluorescence probe, RIH (rhodamine–isatin hybrid) for Al3+ has been designed and synthesized. This new dual signal (colorimetric and fluorogenic “off–on” type) chemosensing ensemble based on the complex between RIH and Al3+ has also been effective to selectively discriminate PPi from other anions in…
The electrochemical properties of Co-Ni layered double hydroxides (LDHs) as efficient electrocatalysts for water oxidation were investigated in potassium phosphate electrolyte under neutral pH condition. The Co-Ni LDHs with a core-shell structure were fabricated using a facile route from a Co-Ni hydroxide precursor wi…
Self-standing single crystalline NiCo2S4 hollow nanorod arrays are prepared for catalysing the polysulfide redox couple in quantum dot-sensitized solar cells (QDSCs). The QDSCs using NiCo2S4 as a counter electrode (CE) achieved a power conversion efficiency of 4.22%, which exceeds the performance of QDSCs based on a P…
Hybrid nanocomposites based on aluminum alloy 6061 reinforced with different hybrid ratios of SiC (0.5, 1.0 and 1.5 vol. %) and B4C (fixed 0.5 vol. %) nanoparticles were successfully fabricated using ultrasonic cavitation based solidification process. The fabricated cast specimens were characterized using SEM study wi…
Nature has evolved multiple enzymatic strategies for the degradation of plant cell wall polysaccharides, which are central to carbon flux in the biosphere and an integral part of renewable biofuels production. Many biomass-degrading organisms secrete synergistic cocktails of individual enzymes with one or several cata…
Surface and interface characteristics of substrates are critical for reliable wafer bonding. Understanding the elemental and compositional states of surfaces after various processing conditions is necessary when bonding dissimilar materials. Therefore, we investigated the elemental and compositional states of silicon…
In this study, highly elastic graphene oxide–epoxy composite aerogel (GEA) was fabricated by a facile method, in which the mixed suspension of the thermoset epoxy precursors and graphene oxide sheets was freeze-dried, followed by a routine curing process. The resulting GEA with a three-dimensional network structure no…
A 1D-microporous 3D calcium tetracarboxylate MOF has been solvothermally prepared and its structure solved from single crystal data. It exhibits coordinatively unsaturated Ca(2+) Lewis acid sites able to trap and deliver nitric oxide at a biological level.
BACKGROUND: Enzyme end-product inhibition is a major challenge in the hydrolysis of lignocellulose at a high dry matter consistency. β-glucosidases (BGs) hydrolyze cellobiose into two molecules of glucose, thereby relieving the product inhibition of cellobiohydrolases (CBHs). However, BG inhibition by glucose will eve…
