A potassium iron (II) hexacyanoferrate nanocube cathode material is reported, which operates with an aqueous electrolyte to deliver exceptionally high capacities (up 120 mA h g-1 ). The exhibits excellent structural integrity, leading fast kinetics and highly reversible properties. All of the battery materials are safe, inexpensive, provide superior high-rate, long-cycle-life electrochemical performance.
Abstract Due to the high theoretical specific energy, lithium–oxygen battery has been heralded as a promising energy storage system for applications such electric vehicles. However, its large over-potentials during discharge–charge cycling lead formation of side-products, and short cycle life. Herein, we report an ionic liquid bearing redox active 2,2,6,6-tetramethyl-1-piperidinyloxy moiety, which serves multiple functions mediator, oxygen shuttle, lithium anode protector, well electrolyte...
Abstract Recent advances in solar‐driven interfacial evaporation (SDIE) have led to high rates that open promising avenues for practical utilization freshwater production and industrial application pollutant nutrient concentration, resource recovery. Breakthroughs overcoming the theoretical limitation of 2D allowed developing systems with rates. This study presents a comprehensive review various evaporator designs achieved pure beyond 4 kg m −2 h −1 , including structural material allowing...
Gold nanorods have significant technological potential and are of broad interest to the nanotechnology community. The discovery seeded, wet-chemical synthetic process produce them may be regarded as a landmark in control metal nanoparticle shape. However, mechanism by which initial spherical gold seeds acquire anisotropy is critical, yet poorly understood, factor. Here we examine very early stages rod growth using combination techniques including cryogenic transmission electron microscopy,...
The advancement of lithium-oxygen (Li-O 2 ) batteries has been hindered by challenges including low discharge capacity, poor energy efficiency, severe parasitic reactions, etc. We report an Li-O battery operated via a new quenching/mediating mechanism that relies on the direct chemical reactions between versatile molecule and superoxide radical/Li O . exhibits 46-fold increase in charge overpotential 0.7 V, ultralong cycle life >1400 cycles. Featuring redox-active...

A Density Functional Theory study of the adsorption energetics various amine compounds on gold(111) surface revealed that preferential binding occurs in under-coordinated sites. The largest energy is obtained when a gold adatom placed fcc position and positioned with nitrogen above adatom. results are compared previous calculations for thiols, phosphines, ethynylbenzene molecules to provide meaningful comparison within consistent computational framework. systematic increase methyl group...

Element response variations under different laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) operating conditions were investigated to identify important factors for selecting an internal standard (IS) quantitative elemental bio-imaging. Analytes covering a range of atomic masses and first ionisation potentials (FIP) selected investigate the signal variation with changes in spot diameter, mass bias cell sampling position. In all cases, IS improved experimental...

Enantioselective anti-L-amino acid antibodies conjugated to gold nanoparticles are shown facilitate the detection of latent fingermarks by interacting with amino acids present in friction ridge secretions. This antibody-based system is particularly effective for enhancement aged and dried on non-porous surfaces, an area unexploited current techniques.
Thermal decomposition of layered zinc hydroxide double salts provides an interesting alternative synthesis for particles oxide.
The thermal transformation of zinc hydroxide sulphate hydrate to oxide has been examined using synchrotron X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and surface area measurements. By collecting diffraction data in situ, we found that the dehydration pentahydrate proceeded discrete steps form anhydrous sulphate. This compound then decomposed a mixture tentatively identified as Zn3(OH)2(SO4)2 at ∼235 °C. At ∼360 °C, final dehydroxylation occurred with...
