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

open access: yesAdvanced 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.

Chalcogen Alloy‐Engineered Te2Se/Si Heterojunctions for Low‐Noise Complementary Metal‐Oxide Semiconductor‐Compatible Short‐Wave Infrared Imaging

open access: yesAdvanced Optical Materials, EarlyView.
A Te2Se/Si heterojunction designed through atomistic simulations reduces oxide‐related traps, dark current, and noise compared with pure tellurium devices. This CMOS‐compatible platform enables short‐wave infrared detection and high‐contrast imaging in a 14 × 14 array, highlighting a scalable strategy for robust, low‐noise SWIR photodetectors and image

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

The Moving to Health (M2H) approach to natural experiment research: A paradigm shift for studies on built environment and health

open access: yesSSM: Population Health, 2019
Improving the built environment (BE) is viewed as one strategy to improve community diets and health. The present goal is to review the literature on the effects of BE on health, highlight its limitations, and explore the growing use of natural ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

open access: yesAdvanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Urban expansion: from compact to fragmented form

open access: yesActa Scientiarum: Technology, 2019
The new urban order in the territorialization of cities, in general, is based on the principles of an ever more fragmented and dispersed growth across the territory.

The Microclimate Design Process in Current African Development: The UEM Campus in Maputo, Mozambique

open access: yesEnergies, 2020
Even if current action towards sustainability in architecture mainly concerns single buildings, the responsibility of the urban shape on local microclimate has largely been ascertained. In fact, it heavily affects the energy performances of the buildings

The Urban Sun Belt: An Overview

open access: yes, 2020
This paper focuses on the 22 metropolitan statistical areas in the Sun Belt with a population of 1 million people or more. Together, they accounted for almost half of all population growth in the entire United States between 2010 and 2016.
