Sulfur/nitrogen co-doped activated carbon fiber is prepared by thermal treatment of thiourea-bonded hydroxyl-rich carbon fiber, which achieves high doping level and electrochemical performance.
Ten dinuclear Ru( ii ) complexes based on the bis[pyrrolyl Ru( ii )] triad scaffold were prepared to evaluate the influence of the central organic linker on the spectroscopic and in vitro photodynamic therapy (PDT) properties of the compounds.
Overview of recent work detailing oxygen-deficient polyoxovanadate clusters as models for reducible metal oxides: toward gaining a fundamental understanding the consequences of vacancy formation on metal oxide surfaces during catalysis.
Metal-carbon core-shell nanostructures have gained research interest due to their better performances in not only stability but also other properties, such as catalytic, optical, and electrical properties. However, they are limited by complicated synthesis approaches. Therefore, the development of a simple method for…
First-principles calculations of a series of representing D–A copolymers demonstrated the strong Super-Exchange couplings induce not only small hole effective mass but also weak electron-phonon couplings, and eventually high thermoelectric power factor.
The influence of tri- n -octylphosphine on the synthesis of CdS crowns around various types of CdSe core nanoplatelets is investigated.
With the decrease of the layers, the SERS activity of TiS 2 in the detection of organic molecules was significantly enhanced.
Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a proc…
Flexible all solid-state hybrid supercapacitors (HSCs) are considered to be significant energy storage devices and are used as major power sources in various real-time applications.
molecular dynamic simulations and phonon dispersion calculations suggest its good thermal and dynamical stability. The SiBi monolayer is a semiconductor with a narrow indirect bandgap of 0.4 eV. Our results show that the indirect bandgap decreases as the number of layers increases, and when the number of layers is mor…
A complex microstructure resulting in SnTe based thermoelectric materials with improved properties in the mid temperature range.
Noninvasive in vivo imaging of hepatic glutathione (GSH) levels is essential to early diagnosis and prognosis of acute hepatitis. Although GSH-responsive fluorescence imaging probes have been reported for evaluation of hepatitis conditions, the low penetration depth of light in liver tissue has impeded reliable GSH vi…
An effort was made to understand the correlation between local distortion at the lattice site with optical and electrical properties of Eu 3+ -doped MNbO 3 (M = Na and K) compounds for their potential application in piezophotonic devices.
), while being stable in the wet state (50% of dry strength), which warrants consideration as biobased absorbent systems. In addition, according to cell proliferation and viability of rat cardiac myoblast H9c2 and mouse bone osteoblast K7M2, the wet-spun ChNF microfibers showed excellent results and can be considered…
Abstract Zinc oxide nanoparticles (ZnO NPs) were hydrothermally fabricated, using hydroalcoholic clove extract. GC-MS analysis demonstrated that Eugenol is the main bioactive compound of the prepared extract. Experiments were designed, based on the central composite design. The effects of different amounts of zinc nit…
Negative or zero thermal expansion (NTE or ZTE) of materials is intriguing for controllable thermal expansion. We report a series of orthorhombic α-Cu2-xZnxV2O7 (x = 0, 0.1, 0.2), in which the volumetric coefficients of thermal expansion are successfully tuned from -10.19 × 10-6 K-1 to -1.58 × 10-6 K-1 in the temperat…
Engineered nanomaterials (ENM) have a potential to modulate microbiota and induce harmful or beneficial effects in the host. However, the causal factors of ENM-induced dysbiosis remain unknown.
Fe-Ni-MOFs with different amounts of Fe are synthesized through a two-step template etching method. Kinetic analysis indicates that Fe-Ni-MOF exhibits prominent intrinsic peroxidase-like activity, which could catalytically oxidize 3,3',5,5'-tetramethylbenzidine (TMB) to produce oxidized TMB (oxTMB) with a blue color.…
A novel Bi 3+ -doped CsZn 6 B 9 O 21 blue phosphor shows an extraordinary narrow-band emission with a FWHM of only 50 nm and excellent thermal stability.
polymerization of aniline gave polyaniline covalently grafted on the FLG surface. Characterization by FTIR, TEM, SEM, XPS, XRD and electrochemistry confirmed the successful conjugation of PANI to FLG. The grafting density of PANI was estimated by thermal analysis to be ∼26%. As the PFPA-mediated coupling chemistry is…
