A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Angewandte Chemie, EarlyView.Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

A tightly-bonded and flexible mesoporous zeolite-cotton hybrid hemostat
Nature Communications, 2019 Achieving rapid definitive hemostasis is essential to ensure survival of patients with massive bleeding in pre-hospital care. It is however challenging to develop hemostatic agents or dressings that simultaneously deliver a fast, long-lasting and safe ...

Simultaneous ammonium and phosphate recovery and stabilization from urban sewage sludge anaerobic digestates using reactive sorbents [PDF]
, 2018 The use of low-cost inorganic sorbents as a new sustainable strategy to enhance the valorization of nutrients (N-P-K), from the urban water cycle (e.g., side streams from sewage sludge anaerobic digestion), in agriculture applications is presented.

Ammonia‐Induced Metal–Organic Framework Membrane Pore Tuning for Hydrogen Separation
Angewandte Chemie, EarlyView.Impurity‐enabled pore tuning is achieved by harnessing trace ammonia, typically regarded as a harmful contaminant, as a reactive agent to modulate the surface structure and flexibility of ZIF‐8 membranes. Ammonia exposure induces partial surface amorphization and local rigidification, shifting the transport mechanism from a flexible to an intrinsic gas‐

Zeolite Clinoptilolite: Therapeutic Virtues of an Ancient Mineral
Molecules, 2019 Zeolites are porous minerals with high absorbency and ion-exchange capacity. Their molecular structure is a dense network of AlO4 and SiO4 that generates cavities where water and other polar molecules or ions are inserted/exchanged. Even though there are
