Thermal Dynamics Induced by Surface Acoustic Waves in Lanthanide‐Doped Core@Multishell Nanoparticles
Advanced Optical Materials, EarlyView.Accurate local temperature readout in integrated nanoscaled devices driven by high‐frequency surface acoustic waves (SAWs) has a strong technological interest. This image illustrates how lanthanide‐doped core@multishell nanoparticles can be employed as local temperature probes in SAW applications.

Lensless Slide Projection: A Demonstrative Experience [PDF]
arXiv, 2006 A 2D transparency may be projected on a diffractive screen by just illuminating it with a filament lamp of the same height. Sharpness of the filament width is naturally related to sharpness on the image, but some peculiar properties makes this experience to be different from a shadow projection case.

Advanced Synthesis &Catalysis, EarlyView.Abstract Unnatural amino acids play a crucial role in advancing protein engineering and drug development. In this study, we present the synthesis of a series of γ‐aryl‐keto‐α‐amino acids through the direct C−H arylation of readily accessible β‐aminoaldehydes and aryl bromides, promoted by hydrogen atom transfer combined with metallaphotoredox catalysis.

Advanced Sustainable Systems, EarlyView.Rigid, lightweight foams for thermal insulation are produced using a universal and scalable method: results are compared between pilot plant trials, four wood residues, pulp, ocean water, and a biosurfactant. Two guidelines for using this method are suggested: use a distribution of rigid wood microparticle sizes and shapes and match the average ...
