Wines from fruits other than grapes: Current status and future prospectus

Abstract: Several tropical, subtropical and temperate fruits although they differ in shape, colour, taste and nutritive values, provide numerous health benefits. Some of the edible fruits ripen within a very short period, usually leading to an overabundance of the fruits when harvested. Many of the fruits are consumed fresh, but large quantities of harvested fruits are wasted during peak harvest periods, due to the high temperature and humidity, poor handling, poor storage facilities and microbial infections. Therefore, winemaking from such ripe fruits or their juices is considered as an alternative of utilizing surplus and over-ripe fruits for generating additional revenues for the fruit growers. This review summarizes current knowledge about the usage of fruits other than grapes for winemaking and elaborates their properties; mainly quality, consumption, nutrition, sensory evaluation and health benefits. Hence, production and commercialization of non-grape fruit wines is the basis for the standardization of technologies for reducing post-harvest losses and contributes to the economy of the existing wine industry.

Colloidal Wurtzite Cu2SnS3 (CTS) Nanocrystals and Their Applications in Solar Cells

Abstract: In the development of low-cost, efficient, and environmentally friendly thin-film solar cells (TFSCs), the search continues for a suitable inorganic colloidal nanocrystal (NC) ink that can be easily used in scalable coating/printing processes. In this work, we first report on the colloidal synthesis of pure wurtzite (WZ) Cu2SnS3 (CTS) NCs using a polyol-mediated hot injection route, which is a nontoxic synthesis method. The synthesized material exhibits a random distribution of CTS nanoflakes with an average lateral dimension of ∼94 ± 15 nm. We also demonstrate that CTS NC ink can be used to fabricate low-cost and environmentally friendly TFSCs through an ethanol-based ink process. The annealing of as-deposited CTS films was performed under different S vapor pressures in a graphite box (volume; 12.3 cm3), at 580 °C for 10 min using a rapid thermal annealing (RTA) process. A comparative study on the performances of the solar cells with CTS absorber layers annealed under different S vapor pressures was cond...
