Summary: Microfluidic emulsion-based droplet systems have the potential for inexpensive and high-throughput experimentation. However, selecting and amplifying single droplets of interest from a large number of other droplets is still a challenge. To overcome this limitation, a system is presented where droplets of interest are collected and positioned on agar surface or microtiter plate. Results show effective isolation of single droplets, allowing for further analysis and processing.

Summary: Inspired by electric toothbrushes, a revolving microfluidic system is developed to generate liquid metal droplets and construct desired elastomers for flexible electronics. The system allows for high-throughput production of droplets with controlled size, and the generated droplets can be used as conductive fillers in a poly(dimethylsiloxane) (PDMS) matrix directly. The resulting elastomers exhibit high mechanical strength, stable electrical performance, and superior self-healing property, and can easily achieve various patterned designs due to the programmable feature of the embedded liquid metal droplets.

Summary: This article reports on the analysis of evaporation kinetics of sessile droplets on generic curved surfaces, showing how the nature and magnitude of curvature influence evaporation behavior. Experimental validation of the analytical model indicates that on convex surfaces, evaporation rates increase due to augmented vapor diffusion domain, while on concave surfaces rates decrease due to droplet confinement. The model also addresses the fact that on concave surfaces, evaporation rate is not directly governed by substrate curvature, contrary to previous literature discussions.

Summary: This work experimentally studies droplet splitting in fractal tree-shaped microchannels. Four flow patterns of droplet splitting are distinguished based on the level of bifurcations. The self-similar variation of droplet pressure and velocity is discussed, and the quantitative examination of the effect of capillary number and droplet size on daughter and granddaughter droplet size distribution is conducted. The results show that tree-shaped networks with a branching angle of 90 degrees perform better in sequential droplet breakup. Asymmetry in breakup accumulates in high-level branch channels. Increasing the capillary number helps maintain the monodispersity of daughter and granddaughter droplets by eliminating the non-breakup regime in low-level branch channels. The performance of droplet splitting deteriorates as the mother droplet size decreases, with more inactive branch channels observed.

Summary: High-entropy alloy nanoparticles (HEANPs) are attracting attention for their tunability and potential in bioapplication. However, it is challenging to prepare ultra-small high-entropy alloy nanoparticles (US-HEANPs) due to their instability. In this study, PtPdRuRhIr US-HEANPs were fabricated and used as multifunctional nanoplatforms for tumor treatment. The US-HEANPs exhibited peroxidase-like activity and photothermal conversion effect, which effectively ablated cancer cells and treated tumors. This work provides new insights into HEANPs fabrication and opens up research on high-entropy nanozymes and their biomedical applications.

Summary: In this study, the tolerance to d-lactic acid and production were improved in Pichia pastoris by introducing a flocculation gene from Saccharomyces cerevisiae (ScFLO1) and a d-lactate dehydrogenase gene from Leuconostoc pseudomesenteroides (LpDLDH). The engineered strain KM71-ScFlo1-LpDLDH achieved a d-lactic acid titer of 5.12 +/- 0.35 g/L in 48 h, which was 2.6-fold higher than the control strain. Transcriptomics analysis revealed the upregulations of genes involved in lactate transport and iron metabolism as the mechanism of increased tolerance to d-lactic acid.

Summary: This study investigated the effects of electrodes on the performance of anaerobic digestion (AD) by using a double-chamber microbial electrolysis cell integrated anaerobic digestion system (MEC-AD) fed with corn stover. It was found that methane yield was enhanced by 80.41% at 0.6 V, but there was a sharp decline in methanogens at 0.9 V, leading to acidification. The synergistic stabilization of both anode and cathode chambers resulted in the overall improvement of the MEC-AD system.

Summary: Vigorous nanomedicine offers significant possibilities for effective therapeutics, and nanovesicles (NVs), including liposomes, exosomes, and cytomembranes, show great potential. However, the complex interactions between NVs and cells, especially the heterogeneous extracellular adsorptions, are difficult to analyze due to transient dynamics. This study tracks single NVs to directly observe extracellular adsorptions and reveals their heterogeneous characteristics. The spatiotemporal tracking provides insights into NVs-cell interactions and inspires nano-investigations in nanomedicine.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
