In this study, we developed a cost‐efficient neural probe by replacing traditional gold with an aluminum‐based Ti/Al/Ni multilayer stack. Optimizing this metal architecture suppressed oxidation and ensured robust electrical stability, achieving signal quality comparable to standard gold probes. It enables a highly accessible and economical solution for

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Automatic Purification of Li Isotopes from Geological Samples by High-Pressure Ion Chromatography
High-quality purification of lithium (Li) is crucial in measuring 7Li/6Li ratios of whole rocks precisely by MC-ICP-MS. Many scholars have proposed traditional manual Li purification methods by cross-combining the types of eluents, types of resin, resin ...

Isotope amount ratio measurements by MC-ICP-MS
多接收器电感耦合等离子体质谱(MC-ICP-MS)是高精度测定同位素比值最常用的两种技术之一,广泛应用于考古学、物源研究、医学、核科学、法医学、地球科学和环境科学等多个学科[1-9]。与传统的热电离质谱(TIMS)相比,MC-ICP-MS的样品引入方式简单,灵敏度高,并具有测量高电离势元素的能力,但它会产生更大的同位素分馏/质量偏倚[1, 7]。用MC-ICP-MS测得锂的同位素比值与真实值之间的偏差高达25%[10] (而TIMS中Li的偏差仅1-2%[11])。 ICP ...

This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Surface‐Functionalized MXene for Enhanced Photocatalytic CO2 Reduction
Poly(catechol/p‐cresol)‐functionalized MXene (f‐MXene) enhances oxidation stability while preserving conductivity, enabling efficient interfacial electron transfer in a Cu/f‐MXene/reduced TiO2 photocatalyst. Strong Cu–f‐MXene synergy promotes CO2 activation and selective CH4 production, achieving a CH4 yield of 18.1 µmol g−1 (>200 × vs.

pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...
