Molecular‐Scale Geometric Control of Organosiloxane Cage Frameworks Via Rigid Organic Bridges

Small Methods, EarlyView.
Rigid phenylene bridges with predefined Si–Ph–Si angles enable molecular‐level control of cage‐type organosiloxane frameworks. Hydrolysis and condensation of meta‐ and para‐bis(triethoxysilyl)benzene in the presence of tetramethylammonium hydroxide yield a mixture of cage trimers and tetramers, and hexamers, respectively, providing a new insight into ...

Formation of Methoxybenzenes from Cellulose in the Presence of Tetramethylammonium Hydroxide by Pyrolysis

Bulletin of the Korean Chemical Society, 2013
Carbohydrates are one of the major groups of organicsubstances on the earth with a simple chemical structurebased on various monosaccharides. They are widespread inplant tissue and can make up about 80% of its dry mass.Recently the pyrolytic characterization of carbohydrates hasgained more and more attention.

Plasma‐Enabled Simultaneous Synthesis and Nano‐Anchoring of TiO2−x Nanolayers on Mesoporous Bio‐Silica for Effective Photodegradation of Tetramethylammonium Hydroxide

SusMat, EarlyView.
A defect‐rich TiO2−x nanolayer was simultaneously synthesized and nano‐anchored on a mesoporous bio‐silica (diatomite) through a rapid, low‐temperature atmospheric‐pressure plasma process in aqueous media. The optimized TiO2−x/bio‐silica composite (DE 700) exhibits oxygen vacancies, an anatase–rutile heterointerface, broad solar‐spectrum absorption ...

Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.
