Extraction of antimony and arsenic from sulphidic concentrates [PDF]
Acta Montanistica Slovaca, 2000 The efficiency of both mineral processing and extractive metallurgy of minerals depends on the separation of individual mineral components and on the exposure of their surface.

High-strength non-firing ceramics by mechanochemical treatment
Advanced Powder Technology, 2020 Abstract Reducing the sintering time/temperature has been long desired. A so-called “non-firing sintering” was previously introduced by authors, without using thermal energy. This method involves the chemical activation of powder surface via ball milling, however, the mechanical strength of solidified bodies by non-firing sintering method is still ...

Advanced Science, EarlyView.A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

Advanced Science, EarlyView.This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

High-Temperature SHS Heat Insulators Based on Pre-Activated Mineral Raw Materials
CrystalsIn this paper, the results of the technological combustion of SHS heat insulators based on mineral origins are presented. It is shown that after mechanochemical treatment of minerals—diatomite—the kinetic characteristics of the combustion process change,

Advanced Science, EarlyView.Fibrotic scarring persistently challenges urethral reconstruction. This study introduces a conformal, wearable ultrasound bioelectronic system that overcomes this by reprogramming fibroblast fate. The device activates a developmental Wnt–FGF10 axis, driving fibroblasts toward a regenerative FGF10+ phenotype that promotes angiogenesis and matrix ...
