Researchers have fabricated GO-wrapped TiO2 (GOx@TiO2) hybrid particles at room temperature by an electrostatic self-assembly process. The construction of GO0.005@TiO2 and the bimodal 1G59B filler as bimodal inorganic fillers is a new approach for achieving high-strength dental composites.
Researchers from the School of Electronic Science and Engineering at Southeast University, led by Prof. Zhenhua Ni and Prof. Junpeng Lu, have developed a pioneering computational spectrometer recently published in PhotoniX. The device utilizes a silicon photonic "Vernier Caliper" concept to overcome the fundamental trade-off between device footprint, bandwidth, and resolution. Operating within an ultra-compact footprint of only 55*35 µm2, the spectrometer achieves an expansive bandwidth exceeding 160 nm and an average algorithm-enhanced spectral resolution of 1.35 pm. This performance establishes a record-breaking bandwidth-to-resolution-to-footprint ratio of over 61.5 µm-2, demonstrating a significant advance for integrated spectrometers.
This breakthrough is achieved through a deep co-design of photonic hardware and computational science, moving beyond simple algorithmic compensation. The hardware architecture features cascaded Trapezoidal Subwavelength Grating Microring Resonators (TSWG-MRRs) that utilize dispersion engineering to suppress resonant periodicity. This deterministic design allows the device to scan a working window over 16 times larger than a standard microring's free spectral range. The system treats the intrinsic resonance peaks as orthogonal measurement bases and integrates an Nvidia Jetson GPU-accelerated unit to achieve real-time reconstruction. The team successfully resolved 49 absorption lines of hydrogen cyanide (H13C14N) with an accuracy exceeding commercial benchtop optical spectrum analyzers, validating its potential for gas sensing, chemical analysis, and lab-on-a-chip applications.
As the AI era accelerates the demand for advanced semiconductor packaging, a global joint research team has developed an Ultrafast Laser Chemical Vapor Deposition (ULCVD) technique. This breakthrough enables maskless, 3D direct-write patterning of highly conductive carbon circuits on all surfaces of transparent glass substrates, solving critical metallization challenges for Through-Glass Vias (TGV) and Redistribution Layers (RDL).
Soil science is undergoing a profound transformation, evolving from its traditional focus on agriculture to a multidimensional discipline addressing some of the most urgent challenges of our time.
Researchers develop light-induced Asp(D)-to-Ala(A) protein editors (LIDAPEs) which enable site-specific residue editing of endogenous protein in living cells, and lay the foundation for a new class of chemical biology tools.
