Microwave Absorption for Detection of Dirac Fermions in SnTe Films
Advanced Materials Interfaces, EarlyView.Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

Valorizacion de derivados de biomasa; produccion de levulinato de etilo con bajo impacto ambiental empleando un heteropoliacido de estructura Preyssler [PDF]
, 2015 El catalizador con estructura tipo Preyssler fue inmovilizado por primera vez mediante la técnica sol-gel en sílice. Este catalizador se utilizó en la esterificación del ácido levulínico con etanol, a 78 ºC para obtener levulinato de etilo.

Advanced Materials Technologies, EarlyView.Lead‐free bismuth halide perovskite memristors exhibit stable low‐voltage resistive switching behavior. The conductance‐activated quasi‐linear memristor model quantitatively reproduces the experimental hysteresis, confirming ion migration‐driven filament dynamics.

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids
Advanced Materials Technologies, EarlyView.This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Vibrational state dependence of ionic rotational branching ratios in resonance enhanced multiphoton ionization of CH [PDF]
, 1989 We show that rapid evolution of a Rydberg orbital with internuclear distance in a resonance enhanced multiphoton ionization (REMPI) process can have a profound influence on the production of molecular ions in alternative rotational states.
