Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Evaluation of a spacecraft nitrogen generator [PDF]
An experiment was completed to demonstrate that low ammonia concentrations in the product nitrogen stream are possible using the staging concept. Mixtures of nitrogen, hydrogen and ammonia were fed into a temperature controlled packed bed ammonia ...

Anoxic nitrification in marine sediments [PDF]
Nitrate peaks are found in pore-water profiles in marine sediments at depths considerably below the conventional zone of oxic nitrification. These have been interpreted to represent nonsteady- state effects produced by the activity of nitrifying ...

A Sustainable Biotechnology Approach for Mineral Separation
Silver‑binding peptides are first identified through phage‐display screening, and then engineered into multifunctional and responsive peptides or proteins. These tailored biomolecules can selectively capture and aggregate silver particles or ions from complex mixtures, enabling rapid and efficient silver separation and recovery.

Plasmonic photocatalytic ammonia decomposition occurs at near‐room temperature on a plasmonic Au nanocone array under visible light illumination. The nanostructure efficiently harnesses plasmonic modes, leading to increased reaction rates upon plasmon decay.

A Cu‐triazole and D‐Cu‐triazole MOF is studied for eCO2RR. After introducing open metal sites and reducing the particle size through a competitive coordination strategy with N,N‐diethylformamide, the defects significantly enhance and alter the catalytic properties with increased selectivity for C2+ products. Abstract Metal–organic frameworks (MOFs) are

Methods for the determination of submicro quantities of total nitrogen, ammonia, amino nitrogen, amides, peptides, adenylic acid, and nitrates [PDF]
In 1935 one of us described micromethods for ammonia, urea, total nitrogen, uric acid, creatinine, and allantoin (1). These methods are adapted for the analysis of 1 to 2 ml. aliquots of dilute solutions, e.g. 0.1 mg. per cent of ammonia or urea, and for

The onset of dehydrogenation in solid Ammonia Borane, an ab-initio metadynamics study
The discovery of effective hydrogen storage materials is fundamental for the progress of a clean energy economy. Ammonia borane ($\mathrm{H_3BNH_3}$) has attracted great interest as a promising candidate but the reaction path that leads from its solid ...

Bimetallic Nanoparticles as Cocatalysts for Photocatalytic Hydrogen Production
Recent developments have introduced bimetallic nanoparticles as effective cocatalysts for photocatalytic systems. This review explores the rapidly expanding research on bimetallic cocatalysts for photocatalytic production of hydrogen, emphasizing the creation of carrier‐selective contacts, localized surface plasmon resonance effects, methodologies for ...
