Mythology Study and Comparison for Quadratic DC-DC Step-up Converters [PDF]
Iranian Journal of Electrical and Electronic EngineeringElectronic systems reliant on solar sources need DC voltage over 50 volts; hence, the use of converters is essential to satisfy client requirements. Converters modify the output voltage based on the input voltage.

Substrate Engineering of SWCNT p–n Junctions for Dual‐Mode Power Generation and Heat‐Flux Sensing
Advanced Science, EarlyView.Through substrate engineering alone, a single‐walled carbon nanotube p–n junction device switches between two functions under uniform infrared irradiation. A low‐absorbance substrate sustains a central hot junction for continuous power generation, whereas high‐absorbance substrates transiently invert the temperature gradient for sensitive heat‐flux ...

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets
Advanced Science, EarlyView.RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.

Advanced Science, EarlyView.A flexible, hexagonally packed artificial dielectric providing a wide range of effective permittivities (εr ≈ 30–1400) without lumped elements was developed for clinical and ultra‐high‐field MRI. Combined with modular passive‐dipole arrays, the system enables adaptable RF field shaping through electric‐ and magnetic‐dipole tuning.
