C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins
Chemistry – A European Journal, EarlyView.C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

European Journal of Inorganic Chemistry, EarlyView.A family of heteroaryl‐iminoalkoxide Sn(II) complexes has been synthesized to investigate structure‐property relationships relevant to atomic layer deposition and metal‐organic vapor deposition. Systematic modification of the ligand architecture reveals a strong influence on volatility and thermal stability for the parent metal complexes.

Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes
FlexMat, EarlyView.Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Dietary impact of agri‐food by‐products on the volatile composition of Tenebrio molitor larvae
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Incorporating Tenebrio molitor larvae as ingredients in common foods is a promising strategy to encourage their consumption. To achieve this, knowing their volatile profile and the factors that may modify the profile is essential. The effect of larval feeding over volatile composition remains under‐researched, for this reason; the ...
