Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, EarlyView.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

Effect of Unit Cell Topology on Dielectric Properties of Periodic Lattice Materials Used for Functionally Graded Insulation

High Voltage, EarlyView.
ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

Effect of Endodontic Sealers on the Bond Strength of Glass Fibre Posts: A Systematic Review

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review evaluated the influence of resin‐based, eugenol‐based and bioceramic endodontic sealers on the bond strength of glass fibre posts cemented with resin cements. Searches were conducted in PubMed, Scopus, Web of Science, Cochrane Library, Google Scholar and Embase, including in vitro studies using human or bovine teeth ...
