Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

The Laochang Pb-Zn deposit can be typically considered as a hydrothermal mineralizing deposit in the Gejiu ore district. Although extensive studies were conducted to understand the mineralizing system associated with the Laochang Pb-Zn deposit through ...

Anatase TiO2 adsorption on 3-aminopropyltrimethoxysilane-modified Al or glass surfaces
Herein, anatase titanium dioxide (TiO2) nanoparticles were prepared by boiling anatase TiO2 in water without using hydrothermal synthesis. This changed the particle diameter because boiling caused particle collision via convection.

Differing Controls on the Cycling of Neodymium in the Atlantic and the Pacific
Abstract Neodymium (Nd) isotopes ratios are regarded as a key proxy for past ocean circulation despite unsettled debate on marine Nd cycle controls, which opposes a “top‐down” hypothesis (surface sources dominate) and a “bottom‐up” hypothesis (sedimentary sources dominate), each with important implications for Nd isotope proxy interpretation.

CVFEM for free convective heat transfer of CuO-water nanofluid in a tilted semi annulus
Influence of adding CuO nanoparticles in the base fluid on flow and heat transfer in an inclined half-annulus was studied considering constant heat flux as boundary condition of hot wall.

Electrospun nanofibre for load‐bearing composite materials. ABSTRACT Electrospun nanofibres are emerging nanomaterials prized for their scalability, high surface area to volume ratio and yield. Their effectiveness in improving the mechanical properties of fiber reinforced composites is widely reported. Nanofibres could activate multiscale toughness and

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Defect‐Free P2‐Type Layered KxMnO2 Cathode Material for Anode‐Free Potassium‐Ion Battery
A defect‐free P2‐type potassium manganese oxide cathode was synthesized via a rapid (≤2 h) microwave heating process with excellent structural integrity, fast K+ diffusion, and high reversibility for next‐generation anode‐free potassium‐ion batteries.
