An investigation into arc detection and fire safety aspects of photovoltaic installations [PDF]
, 2012 The number of PV systems around the world is increasing and the systems are aging with little to no inspections and maintenance. Exposed to UV, the weather and rodents cables, connection points and other components can degrade to the point where there is

Arcs, Caps and Generalisations in a Finite Projective Space
MathematicsArcs and caps are fundamental structures in finite projective spaces. They can be generalised. Here, a survey is given of some important results on these objects, in particular on generalised ovals and generalised ovoids.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
Advanced Materials, EarlyView.A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Derivation of forces acting on the liquid weld metal based on arc pressure measurements produced using alternating shielding gases in the GTAW process [PDF]
, 2013 As part of an ongoing process to fully evaluate the effects of an alternating shielding gas supply on the gas tungsten arc and gas metal arc welding processes, a comparison between arc pressures produced using argon, helium, alternating gases and GTAW-P ...

Identification and response strategy for pantograph-catenary contact loss in high-speed railway
机车电传动Transient disconnection between pantographs and catenaries during train operation on electrified railways, known as pantograph-catenary contact loss, can cause issues like over-current, creating safety hazards and consequential disruptions to operational

Fragment-level FAIRness: annotating scientific data and its provenance using data fragment selectors
Journal of Integrative BioinformaticsScientific communication depends on the production of FAIR (findable, accessible, interoperable, reusable) data. Yet when datasets are shared, they remain hard to interpret across domains because annotations are tied to heterogeneous file formats and ...

Breaking the Surface: Buoyant Metal–Polymer Open–Cell Hybrid Lattice Metamaterials
Advanced Materials, EarlyView.Open‐cell metal–polymer lattice metamaterials that defy sinking. (a) Injection process of the polyurethane (PU) foam into the titanium (Ti‐6Al‐4V) hollow‐strut lattice creating the open‐cell Ti‐6Al‐4V+PU hybrid lattice, (b) flotation test of a hybrid lattice specimen, and (c) a digital representation and experimental validation of a marine buoy ...

Advanced Materials, EarlyView.Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)
