Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Nitrate, ammonium and urea nitrogen as fertilizers for wheat and rye in a field experiment
In a five-year field experiment on a well-limed sandy soil five nitrogen fertilizers were compared. They were urea, ammonium sulphate, calcium nitrate, calcium ammonium nitrate and a mixture of ammonium sulphate and calcium nitrate.

Programmable Functional Silicification of DNA Origami Nanostructures
This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Aqueous ammonium‐ion batteries (AAIBs) face a hydrogen‐bond paradox: the HB network enables fast NH4+ transport but triggers water decomposition. This review dissects this dilemma, evaluates multiple electrolyte engineering strategies, and outlines four future directions for next‐generation AAIB design ABSTRACT Aqueous ammonium‐ion batteries (AAIBs ...

Why do specific proteins accumulate on “non‐fouling” surfaces? Quantitative proteomics and structural analysis reveal surface‐exposed arginine as the key molecular determinant. ABSTRACT The protein corona determines the biocompatibility of medical devices, yet predicting its composition on anti‐fouling surfaces remains challenging.

Extraction of globulin and albumin from Cerasus humilis by binary aqueous two-phase system
In order to optimize the extraction conditions, an binary aqueous two-phase system (BATPS) composed of ethanol and acetone(volume ratio is 1∶2) and ammonium sulphate is selected to extract globulin and albumin from Cerasus humilis seeds. The distribution
