Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

Advanced Materials Technologies, EarlyView.
The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited

Two‐Step Thermal Upcycling of Flexible Printed Circuit Board Waste Into Metallic Copper Nanoparticles: Synthesis and Characterization

Advanced Materials Technologies, EarlyView.
A two‐step thermal upcycling process converts flexible printed circuit board waste into high‐purity copper nanoparticles using polymer degradation and arc discharge. The synthesized nanoparticles exhibit controlled morphology and high metal purity.

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control

Advanced Materials Technologies, EarlyView.
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Short and Length‐Independent Group Delay Supported by Topological Edge States in Finite‐Size Su–Schrieffer–Heeger Chains

Advanced Materials Technologies, EarlyView.
This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Divine Will and Desire Theories

Discussion of an ethics of divine commands continues to evolve. Two proposed modifications to the traditional theory are considered. First, a dispute has arisen whether a theory grounding ethics in God is better expressed as a “divine command” or “divine

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains

Advanced Materials Technologies, EarlyView.
Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

Advanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Angled Nozzle Aerosol Jet Printing to Streamline Conformal Patterning of Electronics

Advanced Materials Technologies, EarlyView.
A modular, angled aerosol jet printhead is demonstrated to streamline patterning on nonplanar surfaces, including 90° step edges and confined internal geometries. A detailed analysis of gravitational settling for a sheathed aerosol flow and deconvolution of oblique deposition and gravitational effects supports the versatility of this approach for ...

Revisiting John Wesley and Divine Command Theory [PDF]

Wesleyan moral theology is often approached teleologically, as a form of either virtue ethics or natural law ethics, and this approach is often motivated by an interpretation of John Wesley’s writings.
