Summary: This paper reports a simple and fast method (<15s) to fabricate microfluidic cloth-based analytical devices (mu CADs) using a common and cheap correction pen. The pen is directly written on a hydrophilic cloth, with the written region acting as hydrophobic barriers and the non-written region constituting the hydrophilic channels. The method allows for the easy fabrication of 2D and 3D mu CADs, and the devices can be used for distance-based quantitative detection of glucose concentrations.

Summary: The study presents a robust and simple method for direct bonding of large-surface and multilayer PMMA substrates, as well as a heated solvent-assisted treatment method to modify the PMMA surface. Organic solvents such as ethanol and isopropyl alcohol (IPA) were used for polymer surface modification and bonding. The described bonding strategy was applied to fabricate lab-on-a-disc (LOD) systems, which can be developed in research organizations with minimal resources. The bonding quality was evaluated through various tests, and the highest bonding strengths were obtained for ethanol and IPA-based specimens, along with the best sealing results for ethanol-bonded specimens at 105 degrees C.

Summary: The use of nanoparticles in nanomedicine has great potential in overcoming the limitations of conventional therapies and improving early diagnosis and follow-up of diseases. Microfluidic systems offer an efficient and cost-effective method for nanoparticle synthesis and screening by simulating dynamic fluid flows and specific microenvironments. Microfluidic devices allow for controlled synthesis of nanoparticles, enhancing batch-to-batch reproducibility, and provide versatile platforms for rapid and efficient in vitro and in vivo screening. This review summarizes the major microfluidic platforms for controlled nanoparticle synthesis, discusses innovative platforms for mimicking in vitro environments and organism-on-a-chip, and evaluates the current challenges and future directions of microfluidic systems in nanomedicine.

Summary: The experiment demonstrates how symmetry-breaking action in space-time can lead to locomotion of a thin circular sheet, allowing it to walk on land and swim in water. The shape asymmetry of the sheet in different modes of locomotion leads to asymmetric interactions with the environment, resulting in different modes of movement.

Summary: This study develops a mild method for encapsulating citral in calcium alginate microcapsules, avoiding UV irritation and acetic acid. Monodispersed oil-in-water-in-oil emulsions are generated as precursors using a capillary microfluidic device. The alginate microcapsules with a uniform structure and monodispersed size are prepared through the gelling process. The study also demonstrates a typical application of citral-containing alginate microcapsules in delaying the oxidation of oil.

Summary: This study evaluates the optical and fluorescent properties of three high-energy materials through calculation and analysis, and finds that DNBT and DNTO have stronger absorbance anisotropy compared to DNAF, with DNBT showing the highest absorbance on the (0,0,1) crystal plane. The number of five-membered rings and the coplanarity of groups in intermolecular non-conjugation interaction potentially improve the material's ability, as analyzed by crystal diffraction and molecular orbital analysis. Furthermore, based on electrostatic potential calculation, the excitation energy of DNBT is lower than DNTO, and the excitation energy of DNTO is lower than DNAF.

Summary: Tunable structural coloration can be achieved in colorless water-in-oil-in-water double emulsion droplets through total internal reflection and interference at microscale concave interfaces. The shell thickness and eccentricity of the core-shell structures are found to be critical for the formation of iridescent structural colors. Only eccentric thin-shell water-in-oil-in-water droplets exhibit structural colors. Importantly, structural colors based on water-oil interfaces are highly responsive to various environmental stimuli including osmotic pressure, temperature, magnetic fields, and light composition. This work expands the applications of droplet-based structural colors to aqueous systems.

Summary: This study investigated the leakage and diffusion of hazardous gases from steam methane reforming equipment using the FLACS software, aiming to optimize the layout of combustible gas detectors. The research findings show a positive correlation between the concentration and diffusion distance of leaked gases and the leakage aperture. The recommended distance between gas detectors and potential leak points varies based on different leak aperture sizes.
