High Resolution ICP-OES: A powerful diagnistic tool for nuclear forensic studies

, 2016
Knowledge of the elemental and isotopic composition of a seized radioactive sample is a key parameter in nuclear forensics. While mass spectrometry is used in most instances for obtaining such data, recent developments in high resolution inductively ...

Spatial and Diurnal Variations in Sodium Content Within Intervertebral Disc Tissue

JOR Spine
Background Daily cycles in tissue osmolarity within the intervertebral disc (IVD) are a biophysical signal that regulates cellular metabolism and arise from deformation of the charged and hydrated extracellular matrix (ECM).

Augmenting ICP-OES Sensitivity for Trace Element Analysis in Crude Oil via High-Efficiency Micro-Ultrasonic Nebulization

Sensitive trace elements analysis in crude oil via inductively coupled plasma optical emission spectrometry (ICP-OES) is highly desirable for the petroleum industry. However, the conventional pneumatic nebulization (PN) sample introduction system suffers

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

Advanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts

Advanced Science, EarlyView.
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.
