Enhancing the Tribological Performance of PLA via Process‐Induced Functional Grading in Masked Stereolithography

Polymer Engineering &Science, EarlyView.
An exposure‐time‐controlled MSLA fabrication strategy enabling filler‐free functionally graded polymers, resulting in up to a 62% reduction in specific wear rate. ABSTRACT Masked stereolithography (MSLA) enables high‐resolution fabrication of photopolymer components; however, the limited tribological performance of neat resins restricts their ...

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.
