Extensive efforts have been devoted to improve the anode performance of a microbial fuel cell (MFC) by using modified carbon-based anode materials, but most of them did not recognize that the power performance measured by the commonly-used varying circuit resistance (VCR) or linear sweep voltammetry (LSV) method was o…
Computational studies of electrochemical reduction of CO2 to CO, HCOOH and CH4 were carried out using tetra-atomic transition metal clusters (Fe4, Co4, Ni4, Cu4 and Pt4) at the B3LYP level of theory. Novel catalytic properties were discovered for these subnanometer clusters, suggesting that they may be good candidate…
Aggregation-induced emission was explored for the visual enhancement of latent fingerprints deposited on wet non-porous surfaces.
Single-feed, efficient, high-gain antennas using partially reflective surface (PRS) with right-hand/left-hand circular polarization (CP) are investigated. Metallic ground plane and a PRS with square patch (SP) arrays at about$0.5\lambda_{0}$height form the Fabry–Perot cavity (FPC) that is fed by a circularly polarized…
Network-forming polymerization of methacrylamide gelatin and acrylamide generates scaffolds with controlled biocompatibility and water affinity.
Rice husk derived carbon–silica composites were applied as anodes for lithium ion batteries for the first time.
OBJECTIVES: The objective of present study was to develop chitosan-based sustained release nicorandil microspheres to reduce the dosing frequency. MATERIALS AND METHODS: The nicorandil-loaded chitosan microspheres were formulated by emulsion crosslinking method. A 3(2) factorial design was employed to study the influe…
Cobalt tungstate (CoWO4) was recently reported as a catalyst that drives the oxygen evolution reaction. Interestingly, the catalytic activity of crystalline CoWO4 is orders of magnitude lower than its amorphous counterpart. In order to better understand the mechanical origin of these observations, herein we study the…
Hypoxia is considered to be a reductive disorder of cells that is caused either by a lack of oxygen or by the dysregulation of metabolic pathways and is thought to play a role in the pathology of diseases including stroke and cancer. One aspect of hypoxia that remains poorly investigated is the dysregulation of cellul…
Single layer graphene nano-gaps are fabricated by applying the method of feedback-controlled electroburning to notched ribbon devices, which are plasma etched from CVD grown graphene that is wet-transferred onto pre-patterned metal electrodes. Electrical and structural characterizations show that nanometer size gaps f…
The possibility of implementing fuel cell technology in Unmanned Aerial Vehicle (UAV) propulsion systems is considered. Potential advantages of the Proton Exchange Membrane or Polymer Electrolyte Membrane (PEMFC) and Direct Methanol Fuel Cells (DMFC), their fuels (hydrogen and methanol), and their storage systems are…
Highway to MOF Ni 2 (dhtp)! 1 hour in boiling water under atmospheric pressure; a cheap synthesis of the linker is also reported.
The present study explores the structural, charge carrier injection and transport properties of a series of thiophene-pyrrole based oligo-azomethines using density functional theory (DFT) methods. Our findings show that the presence of a bulky substituent adversely affects these properties. However, the electronic eff…
We present a proof-of-concept of the application of gold nanotriangles in sequence specific DNA detection, using localized surface plasmon resonance (LSPR) spectroscopy and dark-field optical microscopy. The sensing platform comprises gold nanotriangles immobilized on a glass chip and oligonucleotides as probes. Probe…
Freestanding lipid bilayers were challenged with 15 nm Au nanospheres either coated by a citrate layer or passivated by a protein corona. The effect of Au nanospheres on the bilayer morphology, permeability and fluidity presents strong differences or similarities, depending on the observation length scale, from the co…
Single-walled carbon nanotubes (SWNTs) possess unique physical and chemical properties, which make them very attractive for a wide range of applications. In particular, SWNTs and their composites have shown a great potential for photodynamic therapy (PDT). SWNTs have usually been used for photothermal therapy; herein,…
Morphology-controlled CuO nanoparticles for electroreduction of CO 2 with an excellent selectivity for ethanol.
Metal organic frameworks (MOFs), an emerging class of porous solid materials, have developed into a constructive research field with intense research interests mainly in the field of materials science and chemistry.
Immersion of capacitive electrodes into a multiple-chamber bioelectrochemical reactor substantially increased energy capture from synthetic river water and seawater.
Computational methods predict the crystal packing of porous organic cage molecules, allowing crystal structure and porosity to be predicted starting from the chemical diagram alone.
