Abstract: A fiber-optic urea sensor based on surface plasmon resonance (SPR) and Mach-Zehnder interference (MZI) combined principle was designed and implemented. By plating gold film on the ...

The buildup of nitrous oxide in the atmosphere is accelerating faster than predicted. This matters because N 2 O is the third most important greenhouse gas and the foremost destroyer of ozone in the ...

The growth of a seed into a seedling, a process known as germination, is the first stage of the plant life cycle. Seeds contain reserves of proteins and other nutrients that must be broken down into ...

Dr. Grace R. Bobkowski (Medicine): A 50-year-old woman was admitted to this hospital because of confusion. The patient had been in her usual state of health until 5 months before the current ...

The most common method of measuring urease activity is to add a colorimetric assay agent for ammonia (e.g., Nessler’s reagent) to a solution of hydrolyzed urea. The absorbance of the solution at a ...

OMEX Agriculture has launched a new urease inhibitor NitroShield, that has been demonstrated to reduce ammonia emissions from urea containing fertilisers by more than 70%,can lift winter wheat yields ...

Quantifying urease activity is an important task for Microbial Induced Calcite Precipitation research. A new urease activity microplate assay using a fluorescent pH indicator is presented. The method ...

Cryogenic electron microscopy has become an essential tool for structure determination of biological macromolecules. In practice, the difficulty to reliably prepare samples with uniform ice thickness ...

Calcium carbonate precipitation and crystallization induced by urease enzyme to solidify soil is known as biocement technology. The uses of waste and cheap materials can make this technology more cost ...
