The use of the well-known methods for testing the content of ammonia in the air of a populated area at the average daily maximum allowable concentration (0.04 mg/m3) is associated with the high requirement for chemical reagents and with considerable time. Deionized water proposed to be used as an absorption solution in the sample collector with the final ion chromatographic determination of ammonia is an alternative to solving the problem and enables air ammonia to be determined with a sensitivity of 0.02 mg/dm3.

Achieving a substantial increase in the ammonia productivity of the Haber-Bosch (HB) process at low temperatures has been a significant challenge for over 100 years. However, the iron catalyst designed over 100 years ago remains at the forefront of this process because it is difficult to exceed the industrial iron catalyst in terms of the ammonia synthesis rate/catalyst volume that determines ammonia productivity in a reactor. Here, a new catalyst with an inverse structure of a supported metal catalyst that consists of metallic iron particles loaded with an aluminum hydride species is reported.

The lactic acid bacterial (LAB) species have proven multifaceted roles in sustainable agriculture due to their biologically safe nature, making them eco-friendly. However, their plant growth-improving mechanisms in stressed and non-stressed conditions are still under consideration. Thus, the current work has been planned to evaluate the drought tolerance potential and plant growth-promoting (PGP) traits of Loigolactobacillus coryniformis BCH-4 in Zea mays L.

We successfully synthesize monodisperse sulfhydryl-modified mesoporous organosilica nanospheres (MONs-SH) via one-step hydrolytic condensation, where cetyltrimethylammonium chloride and dodecyl sulfobetaine are employed as dual-template agents with (3-mercaptopropyl)triethoxysilane and 1,2-bis(triethoxysilyl)ethane as the precursors and concentrated ammonia as the alkaline catalyst. The prepared MONs-SHs deliver a large specific surface area (729.15 m g), excellent monodispersity, and homogeneous particle size.

In this study, square-star-shaped leaf-like BiVO nanomaterials were successfully synthesized using a conventional hydrothermal method. The microstructure, elemental composition, and gas-sensing performance of the materials were thoroughly investigated. Morphological analysis revealed that BiVO prepared at different reaction temperatures exhibited square-star-shaped leaf-like structures, with the most regular and dense structures formed at 150 °C, exhibiting a large specific surface area of 2.

Chronic Kidney Disease (CKD) is a disorder that affects over 10% of the global population, and that would benefit from innovative methodologies that would provide early detection. Since it has been reported that there are high levels of urease in CKD patients' saliva, this sample is a promising non-invasive alternative to blood for CKD detection and monitoring. This work introduces a novel 3D µPAD for quantifying urease activity in saliva in a range of 0.
