Osmium in seawater : analysis and geochemistry [PDF]

, 1998
A method for the direct analysis of seawater osmium has been developed and is described in this thesis. Low and constant blanks are obtained (0.12 pg osmium with 187Os/186Os=2.6) and spike-sample equilibration is achieved using this method.A 191Os ...

Fabrication of crystals from single metal atoms [PDF]

, 2014
Metal nanocrystals offer new concepts for the design of nanodevices with a range of potential applications. Currently the formation of metal nanocrystals cannot be controlled at the level of individual atoms. Here we describe a new general method for the

Time‐Multiplexed Organic Electrochemical Transistor for Saliva‐Based Rapid Detection of Viral Proteins

Advanced Science, EarlyView.
A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Emulsion Liquid Membranes Based on Os–NP/n–Decanol or n–Dodecanol Nanodispersions for p–Nitrophenol Reduction

Molecules
Membrane materials with osmium nanoparticles have been recently reported for bulk membranes and supported composite membrane systems. In the present paper, a catalytic material based on osmium dispersed in n–decanol (nD) or n–dodecanol (nDD) is presented,

Electronic structures of osmium dinitrides and dinitrogen molecule activation by the osmium atom [PDF]

, 2002
Density functional theory and ab initio electron-correlation methods have been used to study structures, stabilities, and bonding properties of osmium dinitrides, and possible mechanisms for the direct insertion of osmium into the strong dinitrogen ...

Don't Store Osmium Tetroxide in Plastic Containers [PDF]

, 2000
It is not safeto store osmium in ordinary laboratory plastic containers. Osmium penetrates polyolefin plastics (polyethylene, polypropylene) to some depth, and reacts with them, so containers made from these plastics or of polystyrene or polycarbonate ...

FGF13 Deficiency Ameliorates Paclitaxel‐Induced Neuropathic Pain by Inhibiting VASH1‐Mediated Microtubule Detyrosination to Promote Mitophagy

Advanced Science, EarlyView.
FGF13 is upregulated in DRG neurons of PIPNP model mice. DRG neuron‐specific knockout of FGF13 ameliorates PIPNP symptoms. Mechanistically, FGF13 potentiates microtubule detyrosination by promoting VASH1 binding to microtubules. FGF13 knockout suppresses VASH1‐mediated microtubule detyrosination and promotes α‐tubulin tyrosination.

Effects of nanomaterials on Cs3Sb photocathode emission performance

AIP Advances, 2022
A new approach to preparing the cesium antimonide photocathode has been developed. A tungsten sponge diffusion barrier layer, instead of the conventional nickel pipe, was used as the evaporation source so that a slow and uniform evaporation of the ...
