Summary: Researchers have developed a method to connect gold and tellurium nanorods on a single DNA origami template without electroplating. By site-specific seeding and annealing at different temperatures, gold and tellurium nanorods were successfully connected, primarily due to the atomic mobility of gold.

Summary: This work explores the use of porous silicon as a SERS-active substrate for near-infrared 1064 nm excitation. Two methods, including the production of porous silicon photonic crystals and the deposition of gold nanoparticles, were discussed for quenching the crystal silicon band-gap photoluminescence. The capability of these substrates for SERS enhancement was evaluated and the advantages and drawbacks of both methods were addressed.

Summary: This study presents the selective separation of nickel and gold ions from real rinse wastewater using the HFSLM technique, with organophosphorus extractant mixtures showing a synergistic effect on target Ni2+ ions but an antagonistic effect on non-target [Au(CN)(2)](-) ions. HCl was found to be the most suitable stripping agent, with high extraction and stripping percentages achieved for Ni2+ ions compared to non-target [Au(CN)(2)](-) ions.

Summary: A lightweight, malleable, lithiophilic, and reticular composite Cu-based current collector was developed using a nylon (PA) framework and a synergized approach of combining Cu/PA with ERGO coating. The 3D grid arrangement and lithiophilic ERGO layer resulted in a dendrite-free Li deposition behavior and impressive electrochemical performance. The synergistic combination of 3D Cu/PA mesh with lithiophilic ERGO coating proved to be a valid path for adjusting Li anodes in flexible wearable devices.

Summary: Uniform macroscopic monoliths of low-density gold foams with high porosity and small diameter pores were prepared by casting and thermal removal of polystyrene core-shell particles. The gold foams showed superior mechanical integrity and resilience compared to previous foams. Efficient gold-plating methods caused morphological transition in the gold coatings and a modified casting approach enabled the synthesis of large uniform monoliths. The mechanical stability and machinability of the gold foam were demonstrated through cutting and nanoindentation measurement.

Summary: This article discusses the importance of magnetic core losses for efficiency and thermal optimization in modern power converters, as well as the limitations of traditional two-winding methods. An improved method for phase shift extraction of a current shunt is proposed and experimentally verified up to 50 MHz. Utilizing this new method eliminates the need for time-consuming component tuning and results in a current shunt design with a phase shift of 0.05 degrees at 10 MHz and a low parasitic inductance of 42 pH.

Summary: In this study, highly efficient and robust Ni-P-based nanoballs (NiPx@HA) grown on hydrophobic asbestos were synthesized for alkaline simulated seawater electrolysis. The strong chemical attachment between the substrate and nickel-rich components, as well as the hexagonal Ni5P4 crystalline modification and fast electron transfer capability contribute to the excellent performance. The versatile strategy allows for multi-elemental doping, flexible substrate employment, and scalable synthesis.

Summary: By depositing a thin and uniform layer of Ni-P complex on a Cu current collector, the lithiophilicity of the collector is greatly improved, reducing the Li nucleation overpotential and suppressing Li dendrite growth. This surface modification method shows promise in developing a stable and cost-effective anode current collector for lean Li-metal batteries.
