Hydrothermal and mechanochemical synthesis of crystalline CaCO
Adsorption Science & Technology, 2017 Mechanochemical and microwave-assisted hydrothermal (MicroWave Treatment [MWT]) procedures were applied to prepare crystalline CaCO 3 . Mechanochemical process was carried out at different speeds of rotation (500 or 850 rpm/min), different duration times

Structural and magnetic properties of mechanochemically synthesized nanocrystalline titanium monoxide [PDF]
, 2012 Nano-sized titanium monoxide (TiO) powder was prepared by mechanochemical synthesis. A mixture of commercial Ti and TiO2 (rutile) powders with the molar ratio of 1:1 was milled in a planetary ball mill for 5, 10, 20, 30 and 60 min under argon atmosphere.

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.

Advanced Science, EarlyView.Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

The unusual microtubule polarity in teleost retinal pigment epithelial cells. [PDF]
, 1988 In cells of the teleost retinal pigment epithelium (RPE), melanin granules disperse into the RPE cells long apical projections in response to light onset, and aggregate toward the base of the RPE cell in response to dark onset.

Progress on the preparation of nanocrystalline apatites and surface characterization: Overview of fundamental and applied aspects [PDF]
, 2013 Nanocrystalline calcium phosphate apatites constitute the main inorganic part of hard tissues, and a growing focus is devoted to prepare synthetic analogs, so-called “biomimetic”, able to precisely mimic the morphological and physico-chemical features of

Advanced Science, EarlyView.How can Sn‐based anodes achieve high capacity and long‐life cycling? This work unlocks the potential anode structure by confining Sn in the A layer of MAX phase with Ti6C octahedra as outer immobilization and Fe as inner anchors. The introduction of Fe dramatically strengthens the Ti–Sn bond to enhance structural integrity, modulate interfacial ...

Advanced Science, EarlyView.Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...
