Life Cycle Assessment of a system for the extraction and transformation of Waste Water Treatment Sludge (WWTS)-derived lipids into biodiesel.

In recent years, the demand for biofuels has been growing exponentially, as has the interest in biodiesel produced from organic matrices. Particularly interesting, due to its economic and environmental advantages, is the use of the lipids present in sewage sludge as a raw material for the synthesis of biodiesel. The possible processes of this biodiesel synthesis, starting from lipid matter, are represented by the conventional process with sulfuric acid, by the process with aluminium chloride hexahydrate and by processes that use solid catalysts such as those consisting of mixed metal oxides, functionalized halloysites, mesoporous perovskite and functionalized silicas.

This study was a cross-sectional, double-observational study.

Methods: RSI and SVHI were administered to 159 singers (amateurs, singing students, and professional singers).

Direct Synthesis of 3-Aryl Substituted Isocoumarins and Phthalides through Palladium Acetate Catalyzed C(sp )-H Activation in Ionic Liquids.

A novel Pd-catalysed oxidative coupling between benzoic acids and vinylarenes or acrylates to furnish isocoumarins and phthalides is reported. The reaction proceeds smoothly in molten tetrabutylammonium acetate via a selective C-H bond activation, with very low percentage of ligand-free palladium acetate as the catalyst, under atmospheric pressure of oxygen. Sub-stoichiometric amount of copper acetate is also required as a reoxidant for the palladium.

Steel slag as low-cost catalyst for artificial photosynthesis to convert CO and water into hydrogen and methanol.

Photoreduction of CO with sunlight to produce solar fuels, also named artificial photosynthesis, is considered one of the most attractive strategies to face the challenge of reducing greenhouse gases and achieving climate neutrality. Following an approach in line with the principles of the circular economy, the low-cost catalytic system (1) based on an industrial by-product such as steel slag was assessed, which was properly modified with nanostructured palladium on its surface in order to make it capable of promoting the conversion of CO into methanol and hydrogen through a two-stage process of photoreduction and thermal conversion having formic acid as the intermediate. Notably, for the first time in the literature steel slag is used as photoreduction catalyst.

The protocol avoids the use of more aggressive and toxic HSO and HCl, that are generally employed on several cellulose sources (e.g.

Psychopathological aspects of dysphagia: a systematic review on correlations with eating disorders and other psychiatric conditions.

Background: The effect of psychopathology on swallowing ability tends to be an overlooked issue in the assessment of dysphagic patients, possibly overshadowed by the given prominence to organic pathologies and the difficulties on the management of these patients. In addition, it should also be kept in mind that a great number of psychotropic drugs can affect swallowing adding problematic clinical issues in this area. Despite this, assessment of dysphagia should be considered as an extremely important issue, due to its impact on basic symptomatology, course of illness and quality of life.

Concerning Synthesis of New Biobased Polycarbonates with Curcumin in Replacement of Bisphenol A and Recycled Diphenyl Carbonate as Example of Circular Economy.

Curcumin (CM) is a natural polyphenol wellknown for its antioxidant and pharmaceutical properties, that can represent a renewable alternative to bisphenol A (BPA) for the synthesis of biobased polycarbonates (PC). In the presented strategy, preparation of the CMbased PC was coupled with chemical recycling of the fossilbased BPA polycarbonate (BPAPC) conducting a twosteps transpolymerization that replaces BPA monomer with CM or its tetrahydrogenated colorless product (THCM). In the first step of synthetic strategy, depolymerization of commercial BPAPC was carried out with phenol as nucleophile, according to our previous procedure based on zinc derivatives and ionic liquids as catalysts, thus producing quantitatively diphenyl carbonate (DPC) e BPA.
