Evaluating Erosional Stability of Reconstructed Mine Landscapes Using Landform Evolution Models: Parameterisation and Decadal‐Scale Erosion Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Ensuring the long‐term erosional stability of post‐mining landforms remains a major challenge in open‐pit mining. Reconstructed landscapes must support the agreed post‐mining land use, such as cattle grazing in the Hunter region of southeastern Australia, requiring stable pasture and minimal soil loss.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Cold spray-friction stir hybrid additive manufacturing of 316L SS: Feasibility, microstructure, and mechanical performance

Materials & Design
Cold spray additive manufacturing of strain hardenable austenitic steels often yields poor properties in the as-fabricated state. The cold spray-friction stir additive manufacturing (CFAM) process, which combines cold spray (CS) deposition with friction ...

Water Drops Sliding Over Arrays of Janus Micropillars With Hydrophilic Tops: A New Mechanism of Drop Charging

Small, EarlyView.
A water drop slides over a distance of a few centimeters across arrays whose top surfaces exhibit a contact angle below 10°. The arrays are fabricated with hydrophilic tops and hydrophobic sidewalls and substrate, forming Janus structures. As the drop moves, it generates a spontaneous electric charge and leaves behind tiny satellite droplets that ...

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures

Small, EarlyView.
Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Origins of Embrittlement of an Al-Zn-Mg-Cu Alloy Post Additive Friction Stir Deposition

, 2023
Additive Friction Stir Deposition (AFSD) is a solid state, bulk, metal additive manufacturing technology that seeks to replace certain castings and forgings wherever it is economically feasible among other applications.
