Application

Arachidic acid was used to study the growth of cadmium sulfide crystals under arachidic acid monolayers[1]. It may be used to compose Langmuir-Blodgett (LB) films[2].

Alumina-Doped Zirconia Submicro-Particles: Synthesis, Thermal Stability, and Microstructural Characterization.

Gregor Thomas Dahl et al.

Materials (Basel, Switzerland), 12(18) (2019-09-08)

Zirconia nanoceramics are interesting materials for numerous high-temperature applications. Because their beneficial properties are mainly governed by the crystal and microstructure, it is essential to understand and control these features. The use of co-stabilizing agents in the sol-gel synthesis of

Stress-induced activation of Nox contributes to cell survival signalling via production of hydrogen peroxide.

Gillian Groeger et al.

Journal of neurochemistry, 109(5), 1544-1554 (2009-04-07)

Reactive oxygen species (ROS) have traditionally been viewed as a toxic group of molecules; however, recent publications have shown that these molecules, including H(2)O(2), can also strongly promote cell survival. Even though the retina has a large capacity to produce

The role of prenucleation clusters in surface-induced calcium phosphate crystallization.

Archan Dey et al.

Nature materials, 9(12), 1010-1014 (2010-11-16)

Unravelling the processes of calcium phosphate formation is important in our understanding of both bone and tooth formation, and also of pathological mineralization, for example in cardiovascular disease. Serum is a metastable solution from which calcium phosphate precipitates in the
