Perchlorate (ClO4?) is widespread in the solar system having been detected on Earth, Mars, chondrite meteorites and lunar samples. On perchlorates expand potential for habitable conditions by lowering freezing point of liquid water formation brines. In future manned space exploration their presence poses a hazard to human health, however, it also represents opportunities as source oxygen fuel. ...

A description compromise optimal criterion formulated in model metals with substandard ma...

Rhodamin B merupakan salah satu zat warna dalam limbah cair hasil proses produksi industri tekstil yang dapat berbahaya bagi kesehatan dan menimbulkan pencemaran ketika dibuang ke lingkungan dengan konsentrasi tinggi. Solusi permasalahan tersebut adalah mengurangi menggunakan metode adsorpsi memanfaatkan bio adsorben satunya daun ketapang telah diaktivasi terlebih dahulu cara mechanochemical. M...

This review summarizes the unique advantages and opportunities offered by mechanochemical process to generate MOF composites.

A large volume of waste mercury chloride catalyst (HgCl2) is generated by calcium carbide-based polyvinyl chloride production in China, which accounts for 30% of global mercury consumption. However, there are few studies on the leaching behavior and risk control of waste catalyst where mercury is in the form of HgCl2, which is more soluble than metal mercury and poses great threat to human heal...

Poly(ethylene glycol) (PEG) is a linear polymer with a wide range of applications in chemical manufacturing, drug development and nanotechnology. PEG derivatives are being increasingly used to covalently modify small molecule and peptide drugs, as well as bioactive nanomaterials in order to improve solubility in biological serum, reduce immunogenicity, and enhance pharmacokinetic profiles. Here...

The present work focused on the synthesis of β-chitosan submicron particles (CSPs) from Todarodes pacificus using mechanochemical techniques. The gladius was submitted to a sequence of mechanical and chemical treatments to synthesize β-chitin (CT), which was further deacetylated to form spherical chitosan submicron particles with an average diameter of ⩽100 nm. The surface morphology of β-chiti...

Flavonoids from Sophora flavescens were selectively extracted by mechanochemical-promoted extraction technology (MPET) after using response surface methodology to determine the optimal extraction parameters. The highest yield of 35.17 mg/g was achieved by grinding the roots with Na₂CO₃ (15%) at 440 rpm/min for 17.0 min and water was used as the sole solvent with a ratio of solvent to solid mate...
