Biodegradable electronics represents an attractive and emerging paradigm in medical devices by harnessing simultaneous advantages afforded by electronically active systems and obviating issues with chronic implants. Integrating practical energy sources that are compatible with the envisioned operation of transient devices is an unmet challenge for biodegradable electronics. Although high-perfor...

By using meterological rockets fitted with specially designed analyzers, samples for microbiological investigation have been taken. The analyzer design prevented extraneous microorganisms from penetrating into the analyzer. Before being used, the analyzers were sterilized with high gamma-ray doses. For the first time microorganisms have been detected in the mesosphere at an altitude of 48 to 77...

A s Leona notes in a recent issue of PNAS (1), art and objects of cultural heritage hold information about the technology, trade, and aesthetics of a people. This knowledge can be accessed through chemical and material analysis combined with an understanding of the history of technology, science, and art. The information learned is of great value, especially for ancient objects that are so old ...

Food colorants from natural sources are preferred over the synthetic variants which elicits various adverse effects including teratogenicity and carcinogenicity. Pigments produced from Monascus spp. are of microbial origin and can be used as food grade biocolorants. The aim of the present work was to investigate the feasibility of Jackfruit seed as a substrate supplemented with carbon sources l...

Many commodities are abundantly produced around the world, including soybean, corn, rice sugarcane, cassava, coffee, fruits, and many others. These productions responsible for generation of enormous amounts daily residues, such as cassava sugarcane bagasses, husk, coffee peel. residues rich sources renewable energy can be used substrates industrial interest products. Microorganisms useful biofa...
