ChemistryEurope, EarlyView.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Assessment of different pre-treatment methods for the removal of limonene in citrus waste and their effect on methane potential and methane production rate [PDF]
, 2016 The objective of this study was to assess the limonene removal efficiency of three pre-treatment methods when applied to citrus waste and to evaluate their effects on the biochemical methane potential (BMP) and the methane production rate (MPR) using

Chemistry – A European Journal, EarlyView.Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis
Chemistry – A European Journal, EarlyView.Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...
