Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Spectrally Programmable Spin‐Polarized Photocurrents in WSe2–NiPS3 Magnetic van der Waals Heterostructures

Advanced Materials, EarlyView.
Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Giant Nonequilibrium Valley Control via Spin‐Selective Hot‐Carrier Transfer in an Antiferromagnetic van der Waals Stack

Advanced Materials, EarlyView.
Spin‐selective hot‐carrier transfer across CrSBr/WSe2/CrSBr interfaces couples the continuously tunable magnetic configuration of antiferromagnetic CrSBr to the valley degrees of freedom of monolayer WSe2, enabling giant nonequilibrium valley control and magnetic‐state‐dependent reversal of circularly polarized emission.

U-shaped bilayer graphene channel transistor with very high Ion/Ioff ratio

, 2011
A novel graphene transistor architecture is reported. The transistor has a U-shaped geometry and was fabricated using a gallium focused ion beam (FIB). The channel conductance was tuned with a back gate.

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...
