We present a rigid-ion model of Ba, zK,BiO, for compositions x = 0.25 and x = 0.40. Partial vibrational density ot states of ions in the compounds Ba,, ,? K,, ,,BiO, and Ba,, (,Ki, ,BiO, are reported at room temperature and 100 K. The oxygen modes dominate the vibrational spectrum from 150 up to 82Ocm ‘. The low frequency modes arc associated with the cations. The number of substituted K around...

Flash photolysis of caged compounds is one of the most powerful approaches to investigate the dynamic response of living cells. Monolithically integrated devices suitable for optical uncaging are in great demand since they greatly simplify the experiments and allow their automation. Here we demonstrate the fabrication of an integrated bio-photonic device for the optical release of caged compoun...

The odour generated by industrial gaseous emissions causing nuisances generally is due to the presence of volatile reduced sulfur compounds (VRSC) Although a number of microorganisms are known for degrading VRSC, the treatment of a mixture of reduced sulfur compounds remains challenging for several reasons. To resolve these problems two-stage systems have been proposed, in the first reactor H 2...

Edible oil extraction is a large and well-developed sector based on solvent assisted using volatile organic compounds such as hexane. The of from oilseeds generates volumes oilseed by-products rich in proteins, fibres, minerals secondary metabolites that can be valued. This work reviews the current status bio-macro-composition oilseeds, namely soybean, rapeseed, sunflower flaxseed, refining pro...

Calendula officinalis L. has been largely known for its topical anti-inflammatory properties; however, there are no experimental evidences about its antiphlogistic effect at the gastric level. To investigate whether marigold might exert an activity against gastric inflammation, a CH2Cl2 extract obtained from C. officinalis flowers was evaluated in vitro on the NF-κB pathway. The lipophilic extr...
