Summary: A facile method based on recyclable nanoscale zero-valent iron-mediated photoinduced reversible deactivation radical polymerization in ionic liquid leads to the synthesis of narrow disperse polymers and diblock copolymers. The synthesized copolymers show stimuli response against pH and temperature variation, and the recyclability of the catalyst and solvent is established. This synthesis strategy opens up new avenues for the preparation of intelligent functional polymers for engineering and biomedical applications.

Summary: A general approach for assembling colloidal microspheres into coupled microcavities using magnetostatic interactions under an external field has been reported. By designing the local field gradient around microspheres, virtual templates can be formed to produce various coupled photonic structures. This method shows promise for easily and efficiently fabricating coupled microstructures for photonic and optoelectronic applications.

Summary: Microwave-induced thermoacoustic imaging (MTAI) is an emerging physical imaging technology that combines the high resolution of ultrasound imaging with the high contrast of microwave imaging and the advantages of deep penetration of microwave. MTAI uses microwave as the excitation source and ultrasound as the information carrier to achieve non-destructive, high-resolution imaging of biological tissue at a depth of centimeters. MTAI has been applied to imaging various biological tissues and detecting multiple diseases, and this paper provides a comprehensive review on its principle, applications, and future development direction.

Summary: Microwave-induced thermoacoustic imaging (TAI) combines electromagnetic radiation and ultrasonic waves to achieve high imaging contrast and submillimeter spatial resolution, making it suitable for detecting material anomalies. The proposed use of non-coherent pulse compression enhances the signal-to-noise ratio of pulsed TAI systems, improving image quality without major system modifications.

Summary: A magnetically driven amoeba-like nanorobot (amNR) is introduced for active drug transport, which can actively extravasate from blood vessels, penetrate into deep tumor tissue, and release the encapsulated doxorubicin (DOX) after magnetic field application. The amNRs can deliver DOX into approximately 92.3% of tumor cells and completely inhibit tumor growth with an inhibition rate of 96.1%. This deformable amNR, combined with magnetic field application, provides a facile strategy for whole-process active drug transport.

Summary: This study investigated the interaction of CdSe/ZnSCOOH QDs with the chorion of rainbow trout eye-egg stage embryos, revealing that QDs induced cardiac toxicity in the embryos. However, no significant differences were found in embryo survival rates and cytotoxicity and genotoxicity effects between fish exposed to QDs for 1 day and those exposed for 4 days. Results also showed the adsorption of QDs aggregates on the outer surface of the chorion leading to oxygen-deficient microenvironment in embryos. These findings are important for understanding the impact of QDs on living organisms and evaluating nanotoxicity to fish at early development stages.

Summary: In this study, the experimental method of quantum gas of ultracold atoms was used to observe hole pairing phenomenon caused by magnetic correlations in a doped antiferromagnetic ladder system with mixed-dimensional couplings. The results showed that magnetic correlations can significantly increase the binding energy of holes and reduce the pair size, allowing holes to predominantly occupy the same rung of the ladder. It was also found that spatial structures in the pair distribution appeared with increased doping, indicating repulsion between bound hole pairs. By engineering a configuration to enhance binding, a strategy to increase the critical temperature for superconductivity was outlined.

Summary: Microwave-induced thermoacoustic imaging (MTAI) using low-energy and long-wavelength microwave photons has great potential in detecting deep-seated diseases by visualizing tissue's electric properties. However, the low contrast in conductivity between a target and the surroundings limits its sensitivity and hinders biomedical applications. To overcome this, a split ring resonator (SRR) topology based MTAI (SRR-MTAI) approach is developed, showing ultrahigh sensitivity in distinguishing saline concentrations and detecting tissue targets. In vitro and in vivo experiments demonstrate significant enhancement in imaging sensitivity, suggesting the potential of SRR-MTAI to tackle previously impossible biomedical problems.

Summary: Grain production in Australia faces challenges due to unfavorable climatic and soil conditions. Deep tillage has shown significant yield responses, but the specific mechanisms are not yet clear. This study suggests that crops respond more to deep tillage than to nutrition interventions, and increased crop transpiration, ear density, and grain number contribute most to yield increases. Crop water use does not seem to be the main driver of yield responses to deep tillage, but rather the hormonal responses affecting crop tillering and development.
