Summary: Platinum(II) coordination-driven architectures have unique features in fabricating functional supramolecular materials with various light-emitting metallacycles and metallacages. The platinum(II) center not only builds metal-ligand bonds, but also benefits the ultimate luminescence due to its unique photophysical traits. This study reveals the function of platinum(II) metallacycles in light-emitting devices, which is expected to apply to other coordination-driven architectures with versatile properties.

Summary: In this study, the authors reported a hierarchical self-assembly strategy to prepare cylindrical aggregates (tubisomes) using an amphiphilic supramolecular bottlebrush polymer and a cyclic peptide nanotube as the noncovalent backbone. The tubisomes were introduced with an aggregation-induced emission (AIE) effect to exhibit excellent fluorescent properties. The fluorescence of both the tubisomes and the anticancer drug doxorubicin (DOX) can be quenched and recovered upon drug release, enabling in-situ imaging of drug release.

Summary: Highly oriented and self-ordered titanium-niobium-iron mixed oxide nanotubes were synthesized through an electrochemical route, with their nanostructure morphologies closely related to the nature of the alloy substrates. Under solar irradiation, the methylene blue degradation rate of Ti-Nb-Fe-O nanotubes increased by 33% compared to TiO2 nanotubes and TiO2 nanoparticle films. The gully-like morphology and rich defects introduced by Nb and Fe co-doping in Ti-Nb-Fe-O mixed nanotube oxides contribute to enhanced photocatalytic degradation performance.

Summary: In this study, a synthetic electrozyme was coupled with a supramolecule-assembled nanoarchitecture to mimic mitochondrial oxidative phosphorylation and achieve enhanced bioenergy transformation. The metal-free electrozyme, a semiconducting polymer deposited on an electrode, exhibited a well-matched electrocatalytic property that allowed the oxidation of reduced nicotinamide adenine dinucleotide (NADH) to release protons at a much lower electric potential. As a result, a proton gradient was generated and drove the rotary catalysis of adenosine 5'-triphosphate (ATP) synthase in a lipid membrane, resulting in the production of ATP. Significantly, the electrochemical bioenergy conversion of NADH to ATP in this bio-like system was much more efficient compared to natural mitochondria. This work integrates synthetic and natural catalytic chemistry, facilitating enhanced bioenergy transformation and greatly improving prospects in ATP-fueled bioapplications.

Summary: The in-vitro corrosion behaviors of extruded Mg-xGa (x = 1, 3, 5) alloys in alpha minimum essential medium (alpha-MEM) were investigated. The bilayer corrosion film was composed of an outer layer dominated by amorphous phosphates-carbonates and an inner layer dominated by MgO-Mg(OH)(2). Pure Mg and Mg-1Ga exhibited low corrosion rates and homogeneous corrosion behaviors owing to the protection from the compact corrosion films. By contrast, Mg-3Ga and Mg-5Ga exhibited high corrosion rates and inhomogeneous corrosion behaviors owing to the bulky micro-galvanic corrosion caused by Mg5Ga2. Based on these results, possible corrosion models were developed.

Summary: This study investigated the effects of Ga content on the microstructure and mechanical properties of hot-extruded Mg-2Zn-xGa alloys. The results showed that increasing Ga content refined the grains and increased the amount of Mg5Ga2 precipitates, leading to enhanced strength properties. However, excessive Mg5Ga2 precipitates resulted in reduced elongation.

Summary: This study examined the microstructures and mechanical properties of a hot-extruded Mg-5Ga alloy after ageing treatment. The results showed that particle-shaped and rod-shaped Mg5Ga2 precipitates were formed in the alloy after peak ageing treatment, leading to significant improvements in yield strength and ultimate tensile strength. These improvements were mainly attributed to the enhanced precipitation strengthening by newly formed fine Mg5Ga2 precipitates. However, high-temperature ageing treatment resulted in coarsening of Mg5Ga2 particles, leading to a decrease in ductility of the alloy.

Summary: A strategy of matched spectral and temporal light management is developed to improve photosynthetic efficiency by co-assembling natural thylakoid membrane (TM) with artificial long afterglow particle (LAP). LAP with excellent stability and biocompatibility is optically-matched with the absorption of TM, serving as an additional light source for photosynthesis. Enhanced photosynthesis is achieved after co-assembly, with boosted electron transfer, oxygen yield, and ATP production due to down-conversion fluorescence emission from LAP. This proof-of-concept work opens a new route to augment the photosynthetic efficiency of green plants by utilizing precise light-managed materials.
