Application

Ammonium chloride (NH4Cl) is an ammonium salt which can be used for a variety of applications such as:
  • a catalyst for the one-pot synthesis of 3,4-dihydropyrimidin-2-(1H)-ones
  • a promoter in the multicomponent synthesis of pyrrolo[3,4-b]pyridine-5-one
  • a reagent to improve the hydrolysis rate of magnesium hydride for the generation of hydrogen
  • a reductant, which facilitates the recovery of metals that are utilized in lithium-ion batteries

Phosphoinositide signaling regulates diverse cellular functions. Phosphoinositide-3 kinase (PI3K) generates PtdIns(3,4,5)P3 and PtdIns(3,4)P2, leading to the activation of proliferative and anti-apoptotic signaling pathways. Termination of phosphoinositide signaling requires hydrolysis of inositol ring phosphate groups through the actions of PtdIns(3,4,5)P3 3-phosphatase

Solid-State Metathesis Materials Synthesis

In the last two decades, a new method termed solid-state metathesis (SSM) has been developed to synthesize compounds that are often difficult to produce conventionally.

A Review of Mesoporous TiO2 Thin Films

In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes. Specifically, we focus on recent developments in TiO2 mesoporous thin films in a combined sol-gel and evaporation-induced self-assembly (EISA) process.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
