Non-invasive, real-time, and continuous monitoring of the trace amount of glucose in near-neutral biofluids is significant for the daily care and treatment of diabetic patients or people with suboptimal health status. Despite improved sensing performance with novel low-dimensional materials or porous structures in various enzymatic and non-enzymatic electrochemical glucose sensors, they still suffer from high cost, poor long-term stability, and performance fluctuations in varied temperature and pH. This work synergistically combines an Au-modified porous laser-induced graphene (LIG) gate electrode with an organic electrochemical transistor (OECT) to create a flexible non-enzymatic glucose sensor. The resulting OECT-based non-enzymatic glucose sensor exhibits significantly enhanced sensitivity in near-neutral biofluids, the limit of detection (LOD) (0.08 μM in pH=7.4), excellent stability over time (degradation of ~10% in 180 days) and against temperature changes (30 °C - 40 °C), self-pH calibration capabilities, and uncompromised sensing performance with shrinking sizes. The highly consistent laser patterning technique and in situ galvanic reduction process for electrode modifications not only provide a simple yet versatile approach to creating low-cost, compact sensing platforms for precise and real-time sweat glucose measurements, but also support scalable production, allowing the correlation study of key biomarkers in sweat and blood. © 2025, The Authors.

Bound states in the continuum(BICs) can make subwavelength dielectric resonators sustain low radiation leakage, paving a new way to minimize the device size, enhance photoluminescence, and even realize lasing. Here, we present a quasi-BIC-supporting Ga As nanodisk with embedded In As quantum dots as a compact bright on-chip light source, which is realized by heterogeneous integration, avoiding complex multilayered construction and subsequent mismatch and defects. The emitters are grown inside the nanodisk to match the mode field distribution to form strong light–matter interaction. One fabricated sample demonstrates a photoluminescence peak sustaining a quality factor up to 68 enhanced by the quasi-BIC, and the emitting effect can be further promoted by improving the epilayer quality and optimizing the layer-transferring process in the fabrication. This work provides a promising solution to building an ultracompact optical source to be integrated on a silicon photonic chip for high-density integration.

Aerospace milestones in human history, including returning to the moon and manned Martian missions,have been implemented in recent years. Space exploration has become one of the global common goals, and to ensure the survival and development of human beings in the extraterrestrial extreme environment has been becoming the basic ability and technology of manned space exploration. For the purpose of fulfilling the goal of extraterrestrial survival, researchers in Nanjing University and the China Academy of Space Technology proposed extraterrestrial artificial photosynthesis(EAP) technology. By simulating the natural photosynthesis of green plants on the Earth, EAP converts CO/HO into fuel and Oin an in-situ,accelerated and controllable manner by using waste COin the confined space of spacecraft, or abundant COresources in extraterrestrial celestial environments, e.g. Mars. Thus, the material loading of manned spacecraft can be greatly reduced to support affordable and sustainable deep space exploration. In this paper, EAP technology is compared with existing methods of converting CO/HO into fuel and Oin the aerospace field, especially the Sabatier method and Bosch reduction method. The research progress of possible EAP materials for in-situ utilization of extraterrestrial resources are also discussed in depth. Finally,this review lists the challenges that the EAP process may encounter, which need to be focused on for future implementation and application. We expect to deepen the understanding of artificial photosynthetic materials and technologies, and aim to strongly support the development of manned spaceflight.

In composites, cracks propagation could be blocked by the second phase with higher modulus. Constructing a continuous network of the stiffer phase to block and deflect the cracks is anticipated to enhance fracture toughness. Herein, we prepared a series of 3D network-structured Si3N4-TiC0.3N0.7 ceramic composites by suspension-coating TiC particles (40 nm) on Si3N4 microspheres (75 μm). Contrary to conventional strong/weak interface (nacre‐like) models, constructing a strong/stronger interface with modulus gradients may enhance the fracture resistance and load-bearing capability of the composites. The optimized fracture toughness of 10.04 MPa m1/2 and significantly rising R-curve (SENB method) both demonstrate the excellent toughening effect of TiC0.3N0.7 networks. The mechanical properties and damage tolerance of sintered composites were evaluated as a function of TiC content. Two distinct crack propagation modes were identified through analysis of surface cracks and fracture morphology. © 2025

Scaling exponents of conductivity-like and resistivity-like Gilbert damping with spin-orbit parameter in oriented hcp Co1−xIrx soft magnetic films

engineering Gilbert damping in ferromagnetic metal films is of great importance to exploit and design spintronic and high-frequency electromagnetic devices. The spin-orbit parameter ξ has been found to be efficient for tuning the Gilbert damping rate αG in a wide range. However, the theoretically predicted cubic (quadratic) scaling of the conductivity-like ασ (resistivity-like αρ) part of αG on ξ has not been verified in real ferromagnetic metal materials. To clarify this relationship, herein, we focus on the damping mechanism in oriented hcp Co1−xIrx soft magnetic films by combining ferromagnetic resonance measurements with first-principle calculations. The αG is found to increase linearly as the Ir concentration x changes from 0.02 to 0.23, where ξ is dominant over other related parameters. In particular, we demonstrate the ξ2.51 (ξ1.69) dependence of ασ (αρ) in oriented hcp Co1−xIrx soft magnetic films by extracting ασ and αρ according to the temperature dependence of αG, which validates the theoretical prediction. The difference in the ξ dependence of the two types of damping is mainly derived from the non-negligible variation in the density of states at the Fermi surface (DEf) induced by ξ. The present results provide a deeper insight into the Gilbert damping mechanism and suggest an approach to tailor the magnetic damping freely in magnetic metallic materials.
