Colloidal quantum dots (CQDs), with high gain, solution processability, tunable emission, and low cost, are promising gain media for next-generation lasers. Yet, electrical pumping—especially surface emission—faces two hurdles: insufficient carrier injection and high optical losses. Prof. Shuming Chen’s team at SUSTech introduced an “electro-thermal-optical co-design,” enabling the first electrically pumped surface-emitting ASE in CQDs, paving the way for QD-VCSELs.

Testosterone is far more than a reproductive hormone—it shapes nearly every aspect of men’s health, from muscle and bone strength to cardiovascular protection and cognitive performance. 

Single-photon sources are pivotal for securing quantum communications and powering optical quantum computers. To overcome their fragility to defects, scientists have pioneered a topological bulk-state "quantum emitter" by coupling semiconductor quantum dots to an irregular 'Q'-shaped cavity. This innovation "locks" photons within a disorder-resistant zone while ejecting them vertically with 92% simulated efficiency. The system demonstrates robust light-matter interaction against structural disorder, enabling topologically protected quantum sources with high efficiency and cavity-boundary imperfection resistance.

A recent review in International Journal of Extreme Manufacturing highlights advances in fabricating compositionally heterogeneous and gradient structures, exploring methods, equipment, and strategies to control interfacial defects.

Developing innovative resource utilization strategies to achieve sustainable recycling of waste-to-fuel is highly desirable, yet the design of cost-effective bifunctional catalysts with dual high-efficiency remains unexplored. While the Fenton-like reaction relies on enhancing peroxymonosulfate (PMS) adsorption and accelerating interfacial electron transfer to improve kinetic rates, CO₂ reduction is constrained by sluggish kinetics and competing hydrogen evolution reaction. Herein, we construct a bifunctional catalyst (NiFe-BNC) featuring dual-atomic active sites by introducing boron atoms into a biomass-derived chitosan substrate rich in functional groups, which optimizes atomic coordination environments. In situ experiments and density functional theory calculations reveal that B-atom modulation facilitates carbon substrate defect enrichment, while the charge-tuning effect between metal sites and “boron electron bridge” optimizes PMS adsorption configurations. This synergistic effect facilitates the interfacial electron transfer and enhances the CO₂ adsorption capacity of NiFe-BNC by 6 times that of NiFe-NC. The obtained NiFe-BNC exhibits significantly enhanced catalytic activity and selectivity, realizing 99% efficient degradation of volatile organic pollutants in the flowing phase within 2 h and stable mineralization exceeding 60%, while achieving a large current density of 1000 mA cm⁻² and CO Faraday efficiency of 98% in the flow electrolytic cell. This work innovatively paves a new way for the rational design of cost-effective functional catalysts to achieve carbon cycle utilization.

Recently, Prof. Jian LU's team (City University of Hong Kong, CityU HK) has engineered breakthrough 3D-printed artificial bone scaffolds. These superelastic scaffolds achieve a high recoverable strain (6% – 7%) and feature on-demand tuning of modulus, strength, permeability, and more. This advancement enables site-specific adaptive solutions for complex bone defects while offering valuable inspirations for multifunctional metamaterials across engineering fields.

Flexible electronic skin (E-skin) sensors offer innovative solutions for detecting human body signals, enabling human–machine interactions and advancing the development of intelligent robotics. Electrospun nanofibers are particularly well-suited for E-skin applications due to their exceptional mechanical properties, tunable breathability, and lightweight nature. Nanofiber-based composite materials consist of three-dimensional structures that integrate one-dimensional polymer nanofibers with other functional materials, enabling efficient signal conversion and positioning them as an ideal platform for next-generation intelligent electronics.

Meanwhile, the review explores the development of multimodal sensors capable of responding to diverse stimuli, focusing on innovative strategies for decoupling multiple signals and their state-of-the-art advancements. Finally, current challenges are analyzed, while future prospects for electrospun nanofiber-based composite sensors are outlined. This review aims to advance the design and application of next-generation flexible electronics, fostering breakthroughs in multifunctional sensing and health monitoring technologies.
