A β-keto ester grouping is a characteristic of ring E of the chlorophylls (Chls). Its presence has also reinforced the original identification of nonfluorescent Chl catabolites (NCCs) as colorless, amphiphilic phyllobilins (PBs). Polar NCCs were also detected in higher plants, in which a free carboxyl group replaced the ring E ester group. Such NCCs are surprisingly resistant to loss of this ca...

The search for electroceramic materials with enhanced ferro-pyro-piezoelectric properties and revealing the perovskite type structure has been the objective of a significant number of manuscripts reported in the literature. This has been usually carried out by proposing the synthesis and processing of new compounds and solid solution series. In this work, several methods to obtain ferro-pyro-pi...

fuel oil used in power plants contain metal impurities like vanadium. after combustion, this metal remains in boiler fuel ash in the form of oxide. in this research, extraction of vanadium oxide from fuel ash has been investigated. two processes were used for this purpose. a pyro- hydrometallurgy and a hydrometallurgy process. in the pyro-hydrometallurgy process, using sodium carbonate, salt ro...

Pyrene mediated noncovalent attachment of a chlorophyll derivative, pyro-pheophorbide a, to a soluble single wall carbon nanotube is reported and the resultant CD, UV-Vis absorbance, fluorescence and 1H NMR spectra are discussed.

Photodynamic therapy (PDT) stands to benefit from improved approaches to real-time treatment monitoring. One method is to use activatable photosensitizers that can both induce cell death (via singlet oxygen) and monitor it (via caspase detection). Here, we report porphyrins as caspase-responsive Forster Resonance Energy Transfer (FRET) acceptors to organic fluorophore donors. Compared to porphy...

An all-fiber pyro- and piezo-electric nanogenerator for IoT based self-powered health-care monitoring has been presented.

Abstract The development of the system document models in field MR-PYRO was done taking into account adaptation application requirements this management system, to organizational and work process particularities specific pyrotechnic field, but also with legislation force occupational health safety, namely Law 319/2006 on safety at methodological rules for its application, as well (Law 126/1995 ...
