Advanced Science, EarlyView.A multifunctional tantalum incorporation strategy enables simultaneous tuning of carrier concentration, mitigation of grain‐boundary scattering, and enhanced phonon scattering in Mg3(Sb,Bi)2. These synergistic effects markedly improve carrier mobility and suppress lattice thermal conductivity, yielding both high material zT and high module conversion ...

Advanced Science, EarlyView.Here, we establish a quantitative relationship between the electrostriction coefficient (Q33) of FRPs and their interplanar spacing (d): Q33 = 100(Δd/d0+1) × Q33(s). Using this model, we fabricated high‐performance soft robots, including a biomimetic crawler (with a speed of 27 cm/s) and a butterfly (with a thrust‐to‐weight ratio of 0.71).

Unconventional Hysteretic Charge Filling in Moiré‐Reconstructed Helical Trilayer Graphene
Advanced Science, EarlyView.In helical trilayer graphene, sequential twisting reconstructs the moiré landscape into periodic domains separated by aperiodic boundaries. Longitudinal transport reveals sweep‐direction‐dependent hysteresis, while the Hall response traces this behavior to hysteretic charge filling at the aperiodic boundaries.

Refrigeration system performance using alternative refrigerants
, 2015 Det Europeiska Parlamentet har visat sin lagstiftande förmåga i och med antagandet av en tuff förordning om reducering av F-gaser. EU Förordningen Nr 517/2014 kommer att fasa ut flourinerade gaser med högt GWP värde och det med en väl definierad nedtrappningsperiod.

Advanced Science, EarlyView.Antimicrobial resistance caused by Gram‐negative bacteria remains difficult to overcome due to the protective outer membrane. To address this challenge, a multi‐condition constrained generative AI framework, GenMTAMP is proposed for de novo membrane‐targeting antimicrobial peptide design by integrating physicochemical and spatial structure descriptors.
