A team of researchers has developed a new class of ultrafast nanomotors powered by near-infrared (NIR) light, opening new possibilities for precise nanoscale transport in water — without the need for chemical fuels.

Myocardial ischemia/reperfusion injury (MI/RI) remains a major therapeutic challenge in acute myocardial infarction due to the lack of effective treatment options. Although mesenchymal stromal cells (MSCs) and their derivatives have shown promise in cardiac repair, their clinical translation is limited by poor delivery efficiency and reduced bioactivity. In this study, researchers developed nanoscale artificial cell-derived vesicles (Rg1-ACDVs) via mechano-extrusion of MSCs preconditioned with ginsenoside Rg1, a bioactive phytochemical. Compared to conventional extracellular vesicles (Rg1-EVs) and unprimed ACDVs, Rg1-ACDVs demonstrated superior therapeutic performance by promoting cell cycle progression and facilitating DNA damage repair, as revealed by multi-omics analyses. Functional assays confirmed their dual ability to scavenge reactive oxygen species (ROS) and safeguard genomic stability in both in vitro and in vivo models. This work underscores the synergistic potential of phytochemical priming and nanoscale bioengineering, establishing Rg1-ACDVs as a scalable and effective platform for advancing MI/RI therapy toward clinical application.

The direct synthesis of semi-conductive quantum dot (QD) inks coordinated by inorganic ions in polar phases presents potential advantages such as low cost and scalability, making it an ideal approach for realizing QDs-based optoelectronic applications. However, the weak repulsive forces between QDs coordinated by inorganic ions can easily lead to agglomeration, significantly limiting size control during the synthesis process. Distinct from the traditional high-temperature injection and low-temperature growth strategy used in the synthesis of QDs with long-chain organic ligands, we discover that low-temperature injection nucleation and high-temperature growth is an effective strategy to achieve controllable tuning of reactive monomers and ligand ions in the direct synthesis system of inorganic ion-liganded QD inks, which in turn realizes the scalable, low-cost, and direct synthesis of uniform and size-tunable short-wavelength infrared (SWIR) PbS QD inks. The yield of single synthesis can be more than 10 g. Compared with the traditional ligand exchange method, the yield is improved by nearly 3 times and the cost is reduced to 7 times. Finally, the solar cell devices fabricated using these PbS SWIR QD inks achieved a photovoltaic conversion efficiency of approaching 9%, confirming the excellent optoelectronic performance of the synthesized PbS QD materials.

In photodetection systems, the ability to simultaneously measure light intensity, wavelength, and polarization is critical for advanced optical applications. A groundbreaking study introduces a novel photodetector leveraging halide perovskites, which uniquely combine electro-optic modulation with polarization-sensitive detection. By utilizing ultrafine nanoripples and micron-sized crystals in perovskite materials, this device achieves precise polarization response and electro-optic modulation. These properties, enhanced by the material’s superior optoelectronic performance, enable multidimensional polarization current generation and visualization key advancements for integrated optical systems. The innovation holds promise for applications in machine learning-driven optical technologies and compact photonic devices, marking a significant step toward multifunctional, high-efficiency optoelectronics.

The bad taste of the drug will seriously affect the patient 's medication compliance, after the mesoporous molecular sieve is loaded with the drug, it enters the channel, the amount of drug in contact with the taste buds was significantly reduced, and reduce the release rate of the drug, so that the bitterness is greatly reduced. In this paper, MCM-41 molecular sieve (MCM-41), MCM-48 molecular sieve (MCM-48)and hollow mesoporous molecular sieve (HMSS) molecular sieves were used as carriers to mask cetirizine for the first time, at the same time, it was compared with aspartame and β-cyclodextrin commonly used taste masking agents, and the drug-loaded complexes were characterized and analyzed by X-ray diffraction and Fourier Transform infrared spectroscopy, the results showed that except aspartame was only physically mixed, the other four materials were successfully adsorbed or included in the drug; among them, HMSS has a drug loading of up to 50 %, and the bitter taste of the drug is not obvious after drug loading. Its taste masking effect is obviously better than other materials, and it is expected to become a new type of high-efficiency taste masking agent.

Recent studies on carbon nanotube (CNT) field-effect transistors (FETs) and integrated circuits (ICs) have shown their potential in radiation tolerance. This work thoroughly examined the SEE of the CNT devices. Using a pulse laser as the irradiation source, the CNT FETs and static random-access memory (SRAM) exhibited an excellent radiation tolerance with a laser threshold energy of 5 nJ/pulse for SEE.

Do renewables always make power cheaper? In the UK, it depends on how much is on the system. Using causal machine learning on 2018–2024 market data, researchers find wind’s causal effect is U-shaped: at low penetration, +1 GWh can reduce prices by up to £7/MWh, the effect weakens mid-range, then strengthens again at higher penetration. The impacts have grown over time as renewables’ share rose, providing an evidence base for market design and support policy. These findings support adaptive support schemes and capacity planning that reflect changing marginal value rather than one-size-fits-all assumptions.

This review presents a comprehensive analysis of the electromagnetic shielding mechanisms, advanced synthesis techniques, and material optimization strategies for ceramic-based electromagnetic shielding materials. Meanwhile, this review discusses the research progress of traditional ceramics (such as oxides, carbides, borides, nitrides and ferrites) and emerging ceramics (such as polymer-derived ceramics, MAX phase ceramics and high-entropy ceramics). Furthermore, the review outlines future research directions in four key areas: microstructure engineering for high-efficiency electromagnetic shielding ceramics, advanced manufacturing technologies, multifunctional integration of shielding properties, and the development of artificial intelligence-driven design approaches for ceramic materials.

Carbon fibers (CFs) are advanced materials that benefit various applications, including light-weight components for aircraft, automobiles and wind turbine blades. At present, the predominant feedstock is expensive polyacrylonitrile. A team of scientists used cheap coal and waste plastics to produce liquefied coals, which were subsequently fabricated into general-purpose and high-performance carbon fibers. This process has the potential to decrease the price of CFs and contribute to environmental and economic sustainability. Their work is published in Industrial Chemistry & Materials on October 3, 2025.
