Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

open access: yesAdvanced Science, EarlyView.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Inside the Microreactor: In Situ Real‐Time Observation of Vapor–Liquid–Solid Growth of Monolayer TMDCs

open access: yesAdvanced Science, EarlyView.
In situ observation of VLS growth in a confined microreactor reveals various growth modes of monolayer TMDCs, including abnormal ribbon growth and particle‐driven growth. The confined space and precursor balance influence droplet behavior and growth dynamics, offering new insights into the controlled synthesis of TMDCs via the VLS mechanism.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Advances in Thermoelectric Thin Films Grown by Atomic Layer Deposition: A Critical Review of Performance and Challenges

open access: yesAdvanced Energy Materials, EarlyView.
This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning

Dissecting Extreme Price Fluctuations in Mineral Fertilizers: Regularities and Co‐Movements in Light of Global Food Security

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Extreme swings in food prices can put food security at risk. Fertilizer prices are among the main drivers of food prices. This work explores the recurrent behavior of the extreme global fertilizer price fluctuations underlying food price dynamics.

Strategic Advocacy for Higher Education Research: Insights From US Agricultural Experiment Station Funding

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Amidst dwindling state funding and the legislative withdrawal from public university research support, a heightened political process shapes the allocation of scarce tax dollars. This article explores how advocacy within the political process influences funding support for higher education from state legislatures.
