This work compares structural and optical properties of silicon nanocrystals prepared by two fundamentally different methods, namely, electrochemical etching of Si wafers and low-pressure plasma synthesis, completed with a mechano-photo-chemical treatment. This treatment leads to surface passivation of the nanoparticles by methyl groups. Plasma synthesis unlike electrochemical etching allows se...

nanoparticles of manganese-dioxide synthesized by mechano-chemical reaction were used foras(iii) and as(v) sorption from water environment. the influence of a milling time of manganese-dioxide on sorption was examined with batch procedure. sorption as a function of contact time was investigated. kinetic of sorption, for both as(iii) and as(v), was fast. the equilibrium condition for milled sorb...

From accumulating studies of hexameric helicases, a mechano-chemical coupling mechanism has emerged which postulates that the nucleoside triphosphate (NTP) hydrolysis is sequentially coordinated together with the binding and translocation of nucleic acid substrate. Various mechano-chemical models have been proposed for different hexameric helicases with no consensus for a common mechanism. To e...

Using organic-base tetramethylammonium hydroxide (TMAH) is a viable, cheap, and fast option for the synthesis of MgZnAl-LDH-type materials by both co-precipitation mechano-chemical methods. TMAH presents several advantages, such as smaller quantity water required in washing step compared to use inorganic alkalis, prevention LDH contamination with alkali cations, its action template molecule tex...
