A series-parallel load-resonant converter for a controlled-current arc-welding power supply [PDF]
A power supply incorporating a series-parallel load-resonant converter, capable of very efficient operation over a wide range of output power is presented. The series-parallel load-resonant converter is shown to have three pairs of resonant frequencies.

Optical Power Converters based on SiC for space applications: the RePowerSiC initiative
The RePowerSiC project has the potential to advance high-power energy transmission technologies for space-based applications. The objective is to develop innovative, ultra-efficient Optical Power Converters (OPCs) using silicon carbide (SiC) for in-space energy transfer at power densities reaching kW/cm2, with conversion efficiencies exceeding 80% over

A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2
A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.
