Immobilization of phosphorescent quantum dots in a sol-gel matrix for acetone sensing

Quantum dots (QDs) are semiconductor nanoparticles (NPs) that are increasingly used in optical sensing applications due to their exceptional optoelectronic properties. When such nanocrystals are doped with certain metal impurities, a phosphorescence-like emission can be obtained, allowing the development of novel robust and highly selective sensing phases (it is possible to perform time resolved measurements enabling a simple discrimination between the luminescence emission from the QDs from the background fluorescence of the sample, in which luminescent lifetime is shorter). In this context, a phosphorescent sensing material for acetone control in water media has been developed based on the immobilization of phosphorescent quantum dots in an inorganic sol-gel solid matrix. For such purpose, colloidal manganese-doped ZnS nanoparticles (Mn:ZnS QDs) surface-modified with l-cysteine (for water solubilisation) were synthesised. The Mn:ZnS QDs exhibit an intense room temperature phosphorescence (RTP) emission in aqueous media even in the presence of dissolved oxygen. Further, a simple and general procedure is proposed to incorporate the colloidal l-cysteine Mn:ZnS QDs in a sol-gel matrix. Application of the developed sensing material to analytical control of acetone dissolved in contaminated water samples was performed based on measurement of the quenching effect of the analyte on the QDs phosphorescence emission. The sol-gel procedure (e.g. nature and concentration of the silica precursors used) employed for immobilization of the QDs was optimized trying to obtain the best analytical features for detection of acetone. The optimized sensing material showed a high selectivity of the sensing material towards acetone. The linear range of the developed methodology turned out to be at least up to 50% acetone:water (v/v) with a detection limit (DL) for acetone dissolved in aqueous medium of 0.16% acetone:water (v/v). The developed sensing phase was finally applied for acetone determination in different spiked water samples, and the recoveries fall in the range of 93-109%.

Comparative life cycle assessment of potassium carbonate and monoethanolamine solvents for CO2 capture from post combustion flue gases

Carbon capture and storage (CCS) has the potential to enable significant reductions in carbon dioxide (CO2) emissions from stationary sources such as coal-fired power stations. The most advanced carbon capture technology is CO2 absorption using amine-based solvents, such as monoethanolamine (MEA). However, there is concern that the increased use of amine-based solvents will lead to other potential negative environmental impacts, such as increased human toxicity. The use of benign inorganic solvents, such as potassium carbonate, which do not degrade in the presence of oxygen or other impurities such as sulphurous or nitrous oxides offer significant advantages over amine-based solvents in terms of environmental impact. A comparative life cycle assessment (LCA) between the use of MEA and the CO2CRC’s potassium carbonate based UNO MK 3 technology for the capture of 1tonne of CO2 from a brown-coal fired power station has been completed. The results reveal that the UNO MK 3 process is significantly better than MEA on ecotoxicity and carcinogen emissions and substantially better on all other indicators. The benefits of the UNO MK 3 process compared with MEA are due to avoidance of emissions from MEA degradation along with the savings in energy use for CO2 removal. The significant environmental benefits of the UNO MK 3 process compared with MEA were not altered by an uncertainty analysis or sensitivity analysis of key inputs and assumptions.

Highly mesoporous and high surface area carbon: A high capacitance electrode material for EDLCs with various electrolytes

Activated carbon fibers (ACFs) with high surface area and highly mesoporous structure for electrochemical double layer capacitors (EDLCs) have been prepared from polyacrylonitrile fibers by NaOH activation. Their unique microstructural features enable the ACFs to present outstanding high specific capacitance in aqueous, non-aqueous and novel ionic liquid electrolytes, i.e. 371 F g-1 in 6 mol L-1 KOH, 213 F g-1 in 1 mol L-1 LiClO4/PC and 188 F g-1 in ionic liquid composed of lithium bis(trifluoromethane sulfonyl)imide (LiN(SO2CF3)2, LiTFSI) and 2-oxazolidinone (C3H5NO2, OZO), suggesting that the ACF is a promising electrode material for high performance EDLCs.

Patents on endophytic fungi related to secondary metabolites and biotransformation applications

Endophytic fungi are an important group of microorganisms and one of the least studied. They enhance their host?s resistance against abiotic stress, disease, insects, pathogens and mammalian herbivores by producing secondary metabolites with a wide spectrum of biological activity. Therefore, they could be an alternative source of secondary metabolites for applications in medicine, pharmacy and agriculture. In this review, we analyzed patents related to the production of secondary metabolites and biotransformation processes through endophytic fungi and their fields of application. We examined 245 patents (224 related to secondary metabolite production and 21 for biotransformation). The most patented fungi in the development of these applications belong to the Aspergillus, Fusarium, Trichoderma, Penicillium, and Phomopsis genera and cover uses in the biomedicine, agriculture, food, and biotechnology industries.

Discovery of a new class of ghrelin receptor antagonists

A series of benzodiazepine antagonists of the human ghrelin receptor GHSR1a were synthesized and their antagonism and metabolic stability were evaluated. The potency of these analogs was determined using a functional aequorin (Euroscreen) luminescent assay measuring the intracellular Ca2+ concentration, and their metabolic stability was measured using an in vitro rat and human S9 hepatocyte assay. These efforts led to the discovery of a potent ghrelin antagonist with good rat pharmacokinetic properties.
