The benefits of publishing research papers first in preprint form are substantial and long‐lasting also in chemistry. Recounting the outcomes of our team's nearly six‐year journey through preprint ...publishing, we show evidence that preprinting research substantially benefits both early career and senior researchers in today's highly interdisciplinary chemical research. These findings are of general value, as shown by analyzing the case of four more research teams based in economically developed and developing countries.
Preprints in chemistry: Benefits? Risks? Tradeoff? The outcomes of our team's nearly six‐year journey through preprint publishing, show evidence that preprinting research substantially benefits both early career and senior researchers in the chemical sciences. These findings are of general value, as shown by analyzing the case of four more research teams based in economically developed and developing countries.
Due to metal leaching and poor catalyst stability, the chemical industry's fine chemical and pharmaceutical sectors have been historically reluctant to use supported transition metal catalysts to ...manufacture fine chemicals and active pharmaceutical ingredients. With the advent of new generation supported metal catalysts and flow chemistry, we argue in this study, this situation is poised to quickly change. Alongside heterogenized metal nanoparticles, both single-site molecular and single-atom catalyst will become ubiquitous. This study offers a critical outlook taking into account both technical and economic aspects.

A large number of immobilized‐Pd‐catalysts for cross‐coupling reactions have been introduced in the last decade. Are the observed catalyzed reactions truly heterogeneous or are they homogeneous due ...to leached palladium? This account critically addresses the leaching issue by selectively referring to some of the newly developed catalytic systems in an attempt to evaluate said systems based on uniform criteria. The report is concluded by identifying the relevant chemical and structural challenges in the field.

A number of new, heterogeneously catalyzed processes to selectively oxidize alcohols into carbonyl or carboxyl compounds have been introduced in the past decade. This study summarizes selected ...methods suitable for scale-up and convenient adoption by fine chemical and pharmaceutical industries to replace conventional oxidative routes based on homogeneous catalysis or on stoichiometric oxidation with inorganic and organic oxidants.
Isolating cellulose from citrus processing waste without employing chemicals has so far been an unfulfilled goal of chemical research applied to the valorization of a widely available biowaste, ...annually totaling >100 million tonnes. We have applied hydrodynamic cavitation using a Venturi-type reactor for the extraction of all valued bioproducts of industrial citrus processing waste in water only, directly on a semi-industrial scale. After reporting the discovery of IntegroPectin in the soluble fraction of the aqueous extract, we now report the isolation of a cellulosic material in the water-insoluble fraction of cavitated lemon and grapefruit processing waste. Named "CytroCell", the material is cellulose of low crystallinity, high porosity, good water holding capacity and good dispersibility in water. These properties open the route to mass-scale production of a useful functional material from a cheap and abundant biowaste.

enhances the activity and the selectivity of the short-gap semiconductor in the sunlight-driven photo-oxidation of trans-ferulic and trans-cinnamic acid ...dissolved in water with air as the primary oxidant. Valuable products such as vanillin, benzaldehyde, benzoic acid and vanillic acid are obtained. This provides the proof of concept that photocatalysis could be a promising technology in tomorrow's solar biorefineries.
Controlled hydrodynamic cavitation is an energy- and chemicals-saving technology increasingly applied to water sanitation and wastewater remediation via mechanical, oxidative, and thermal degradation ...of chemical and biological pollutants, including recalcitrant contaminants. Reviewing the advances that have allowed hydrocavitation to emerge as an economically and technically viable environmental technology, we identify the key design parameters that decide its efficacy in degrading biological and chemical contaminants. The ongoing renewable energy boom, lowering the cost of electricity across the world, will only accelerate the adoption of hydrodynamic cavitation as an eminent technology of our common path to sustainability, with energy and clean water access for all.
The electrocatalytic oxidation of alcohols mediated by TEMPO‐like nitroxyl radicals is an economically and industrially viable method that will shortly find commercial application in the synthesis of ...valued substances including active pharmaceutical ingredients (APIs), valued natural product derivatives, fine chemicals, and valued nanomaterials.
Upping the TEMPO: The electrocatalytic oxidation of alcohols mediated by TEMPO‐like nitroxyl radicals offers key economic and technical advantages that, along with its versatility, will make the method attractive to fine chemical and pharmaceutical companies.

Used by nearly 60 % of the world's population, social media are highly interactive websites (“platforms”) today widely used also by researchers. This perspective aims at identifying the main benefits ...of social media utilization by chemistry scholars with respect to the three main dimensions (research, education and societal service) of scholarly activity. The main risks arising from the use of social media, as we suggest in the conclusions, must be managed and new education on their purposeful utilization should be planned and delivered
What are the benefits of using social media for chemistry scholars? Are benefits limited to research, or they involve also teaching and societal service scholarly activities? What are the main risks of social media utilization, and how can education on purposeful utilization of social media be optimally planned?
