Abstract In this chapter, we aim to explain the chromic phenomena observed in “soft crystals”. Accordingly, basic principles for comprehending fundamental photophysical properties of molecular monomers, such as electronic absorption spectra and luminescence properties, are introduced. Moreover, dimers crystals explained terms intermolecular interactions excited states.

CP titanium was polished with a colloidal silica suspension and chromic oxide slurry under low and high pressures. The polished surfaces were characterized by means of EPMA and XPS. Irrespective of polishing pressure, colloidal silica suspension successfully created a mirror-like surface that was clean at EPMA level. However, XPS detected a small amount of silicon on the outermost surface. On t...

Daily exposure under solar ultraviolet (UV) and infrared (IR) is prone to cause skin cancer photoaging. Real-time monitoring of the environmental UV index IR radiation temperature during outdoor activities can enhance awareness strengthen personal protection. It a challenge design flexible, wearable devices (with measurement capabilities) that be integrated with apparels. Here, microfluidic spi...

We established a new "ecological" Grocott stain for demonstrating fungi, based upon a 4R principle of refusal, reduction, reuse, and recycle of waste management. Conventional Grocott stain employs environmentally harsh 5% chromic acid for oxidization. Initially, we succeeded in reducing the concentration of chromic acid from 5% to 1% by incubating the solution at 60°C and using five-fold dilute...

Nafion films incorporating cationic nickel complexes [Ni(II)(acac)(R4en)](+) (acac = acetylacetonato, R4en = tetraalkylethylenediamine) that exhibit chromic behavior in response to temperature changes and solvent molecules in the vapor and liquid phases have been prepared.
