Metal complex of the Bronze Age from an Alakul burial ground (typology and manufacturing techniques)

Вестник археологии, антропологии и этнографии, 2016
The article deals with metal artifacts from an Alakul burial ground, which is considered to be one of the largest and brightest monuments of the Alakul culture in the Trans-Urals. There is a description of morphological and typological characteristics of

Enhancing Cycling Stability of Aqueous Aluminum‐Metal Batteries via LaCl3‐Modulated Interfacial Reactions

Advanced Science, EarlyView.
In the aqueous AlCl3 electrolyte of aluminum‐metal batteries, the introduction of LaCl3 adjusts the solvation structure of Al3+ and enhances its diffusion level. The oxide precipitate formed by La3+ covers the aluminum metal anode and effectively alleviates corrosion reactions, thereby improving the cycling stability of the battery.

A Tangentially Sensitive Tactile Sensor Reveals the Stick‐Slip Mechanism and Enhances Robotic Tactile Sensing

Advanced Science, EarlyView.
An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

A Janus‐Like Bio‐Inspired Strategy for 3D‐Printed Bimetallic Metamaterials with Excellent Thermal‐Protection and Load Bearing Capacity

Advanced Science, EarlyView.
A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.

Tailoring Rheological and Functional Properties of Nickel‐Mangan‐Cobalt‐Based Recyclate Cathodes from Direct Recycling of Lithium‐Ion Battery Production Scrap

Batteries &Supercaps, EarlyView.
Direct recycled cathodes from electrode production scrap show improved performance by adding binder and conductive additive or blending recycled and fresh slurries. The rheological, microstructural, and functional properties could be matched to pristine material.
