Active chitosan/PVA films with anthocyanins from Brassica oleraceae (Red Cabbage) as Time–Temperature Indicators for application in intelligent food packaging
TL;DR: In this paper, a Time-Temperature Indicator (TTI) based on a PVA/Chitosan polymeric doped with anthocyanins was used to detect changes in the pH of packaged food products when subjected to improper storage temperatures.

Review on the development of natural dye photosensitizer for dye-sensitized solar cells
Norasikin Ahmad Ludin,A. M. Al-Alwani Mahmoud,A. M. Al-Alwani Mahmoud,Abu Bakar Mohamad,Abdul Amir H. Kadhum,Kamaruzzaman Sopian,Nor Shazlinah Abdul Karim +6 more
TL;DR: The photostability of the DSSC sensitizer material must be capable of undergoing many redox cycles without decomposition, and must also have the ability to carry attachment groups, such as phosphonate or carboxylate, to promptly graft it to the TiO2 oxide.

Powering the planet: Chemical challenges in solar energy utilization
Nathan S. Lewis,Daniel G. Nocera +1 more
TL;DR: Solar energy is by far the largest exploitable resource, providing more energy in 1 hour to the earth than all of the energy consumed by humans in an entire year, and if solar energy is to be a major primary energy source, it must be stored and dispatched on demand to the end user.

Dye-sensitized Solar Cells
TL;DR: The dye-sensitized solar cells (DSC) as discussed by the authors provides a technically and economically credible alternative concept to present day p-n junction photovoltaic devices, where light is absorbed by a sensitizer, which is anchored to the surface of a wide band semiconductor.

Antimicrobial activity of flavonoids
T.P. Tim Cushnie,Andrew J. Lamb +1 more
TL;DR: Several high-quality investigations have examined the relationship between flavonoid structure and antibacterial activity and these are in close agreement, and future studies may allow the development of a pharmacologically acceptable antimicrobial agent or class of agents.
