Cloud Inspired White and Grey Plasmonic Metasurfaces for Camouflaged Thermal Management

open access: yesAdvanced Materials, EarlyView.
Inspired by clouds' role in Earth's thermal management, this work presents disordered plasmonic metasurfaces that mimic their radiative effects. The white metasurface enhances backscattering, acting as a cooling layer with camouflage properties.

High Performance P‐Channel Transistor Based on Amorphous Tellurium Trioxide

open access: yesAdvanced Materials, EarlyView.
This study introduces a breakthrough in p‐channel transistors by transforming crystalline 2D tellurium into amorphous tellurium trioxide (a‐TeO3) via UV‐O3 treatment. This transformation enhances electronic properties, resulting in transistors with reduced hysteresis, superior on/off characteristics, and low barrier height, highlighting the potential ...

Evidence that birds sleep in mid-flight

open access: yesNature Communications, 2016
Many birds fly non-stop for days or longer, but do they sleep in flight and if so, how? It is commonly assumed that flying birds maintain environmental awareness and aerodynamic control by sleeping with only one eye closed and one cerebral hemisphere at ...

Songs of Birds [PDF]

open access: yesNature, 1880
YOUR correspondent “A. N.” (antea, p. 97) does not seem to be aware that the best observers are nowadays agreed in believing that the hen cuckoo does not sing. Hence his suggestion in regard to the difference of note observed by Mr. Birmingham (antea, p. 76) hardly applies to the case in question.

Thermionics in Topological Materials

open access: yesAdvanced Materials, EarlyView.
Thermionics is one of the fundamental energy conversion mechanisms in solid state systems. Recent development in topological materials opens new avenues in developing thermionic systems and devices. Due to the linear energy dispersion and topological protection of charge transport, these new materials are promising candidates for high efficiency ...

Machine Learning‐Enhanced Modular Ionic Skin for Broad‐Spectrum Multimodal Discriminability in Bidirectional Human–Robot Interaction

open access: yesAdvanced Materials, EarlyView.
A machine learning‐enhanced modular ionic skin with broad‐spectrum multimodal sensing is realized through a synergistic material–algorithm optimization strategy. This strategy involves hard‐segment‐modulated 1D/2D/3D‐ionic conductors and a data‐driven decoupling model trained on a curated multi‐stimuli dataset.

Preen Gland-Secreted Alkanols Enhance Male Attractiveness in Parrots [PDF]

open access: yes, 2008
The skin glands are widely used in pheromone production throughout the vertebrate worlds. Growing evidences show that birds also have chemical communication, but the uropygial (also called preen or oil) glands, serving as only specialized skin glands of ...
