Mesoporous Copper‐Based Metal‐Organic Framework Flakes as a Promising Platform for Electrosynthesis of Ethylene from Carbon Dioxide

Developing practical electrocatalysts for carbon dioxide electroreduction (CO2RR) requires a synergy of sustainable synthesis and high performance. Here, we report a one-pot green synthesis of a flake-like, mesoporous copper-based metal-organic framework (Cu-MOF) optimized for CO2 conversion. Spectroscopic analysis confirms a coordination environment of Cu2+ centers tetragonally bonded to nitrogen atoms, characteristic of zeolitic imidazolate frameworks (ZIFs). This flake-like architecture an...

High-Voltage Power-Line Conductor Anomaly Detection Using Magnetic Field

This paper introduces a contactless, fully passive approach for locating faults in transmission line conductors. The method relies on the magnetic fields generated by the line current and captures them using low-cost, three-axis magnetic sensor integrated into a custom-designed drone payload. Unlike traditional inspection techniques, the proposed system performs rapid, multi-position magnetic scanning around the conductors within a short time window. By analyzing the spatial variations and te...

Plant-Wide Evaluation of Temperature-Phased anaerobic digestion for internal carbon recovery at a Large-Scale water resource recovery facility

Resource recovery technologies are often evaluated against their own primary performance metric in isolation, without assessing simultaneous consequences across the full plant operational space. This study evaluates temperature-phased anaerobic digestion (TPAD)-derived internal carbon recovery at a full-scale water resource recovery facility (WRRF) and assesses the simultaneous impacts on nitrogen compliance, energy demand, clarifier stability, and biogas recovery across the full operational ...

Non‐linear pathways of/for social and spatial justice research

‘Research, engagement, activism’ appears to indicate a linear path in action-oriented geographical scholarship. It imagines a researcher, bringing their scholarly question/interest to a process of engagement with an issue or place, which then contributes to existing or new activism. In practice, this linear narrative is often disrupted and complicated by what counts as research, outside and within formal education and research institutions, as well as by non-linear personal and collective tra...

Raising galaxy rotation curves via dressing

We present a manifestly diffeomorphism-invariant simple model of galaxy dynamics obtained by applying the dressing field method (DFM) to a general relativistic system comprising the metric and four scalar fields, phenomenologically representing the four-velocity of a cosmological fluid or dust field. The DFM, a systematic tool for extracting the gauge-invariant content in general relativistic theories, provides a physical coordinatization that yields corrective terms to the rotational velocit...
