Multimodal Structural Color Graphics Based on Colloidal Photonic Microdome Arrays
Advanced Functional Materials, EarlyView.A hybrid photonic system combining colloidal crystals and microscale domes is designed to achieve four switchable optical states via the interplay of Bragg reflection and TIR interference. The graphics composed of the photonic microdome arrays provide tunable, angle‐sensitive structural coloration and concealed‐to‐revealed transitions, offering a ...

Agricultural price policy in the Republic of South Africa, the Southern African Customs Union, and food security in Botswana [PDF]
This analysis is concerned with the direct impacts of the regulation of food markets under SACU on food security in the BLS countries. There are two basic rules in SACU determining trade in food and non-food products (Ettinger, 1974; Maasdorp, 1986). The

Alkali Ion‐Incorporated HfO2 Dielectrics for Reconfigurable Neuromorphic Computing
Advanced Functional Materials, EarlyView.This work presents an indium gallium zinc oxide (IGZO) transistor with an alkali cation‐integrated hafnium dioxide (HfO2) dielectric exhibiting synaptic behavior via ion retention. The solution‐based film fabrication strategy overcomes the limitations of atomic layer deposition (ALD) and precursor coating, enabling the control of synaptic retention ...

Advanced Functional Materials, EarlyView.Electrochemical abuse transforms thermal runaway behavior in lithium‐ion batteries. Through systematic decoupling of degradation mechanisms, this study reveals that lithium plating lowers the onset temperature by 10 °C, electrolyte consumption delays high‐temperature reactions, and capacity fade reduces total heat generation. These mechanistic insights

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting
Advanced Functional Materials, EarlyView.A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...
