Summary: Although natural emulsifiers have drawbacks when used alone, their emulsifying ability and stability can be improved when used in combination. This study prepared monodisperse emulsions stabilized by combining two natural protein emulsifiers and examined the influence of various factors on the emulsion's microstructure and stability. The results showed that the emulsions stabilized by mixed protein emulsifiers exhibited better stability and were more resistant to high salt concentrations compared to synthetic emulsifiers.

Summary: Acoustofluidic techniques are widely used for manipulating nano- and micro-particles in microfluidics. This work developed and modeled two hybrid acoustofluidic devices, a double surface acoustic wave (SAW) transducer and a PZT-SAW transducer. The numerical study showed that these devices achieved higher acoustic pressure and particle velocities in the microchannel, and the amplitude and distribution pattern of the pressure can be controlled. The particle trajectories demonstrated that both SAW-SAW and PZT-SAW configurations generated significantly higher acoustic pressure and particle velocity. This study provides new insights for designing acoustofluidic devices with multiple SAW transducers to efficiently manipulate micro- and nano-particles.

Summary: This study introduces lentil protein-based fibrillar gel particles (FGPs) that can form stable emulsions with improved stability. The heating time significantly impacts the particle size and surface hydrophobicity of the FGPs. The FGPs prepared by 4 hours of heating showed small size and increased surface hydrophobicity, allowing them to better adsorb at the oil-water interface and completely cover the oil droplet surface, resulting in stable emulsions with small size and superior long-term stability.

Summary: The geometry variations of mathematical billiard tables can result in various dynamical behaviors, and changing the mass distribution of the colliding particle can also lead to a rich spectrum of dynamics. The study explores different families of billiards with varying table geometry and particle, showing that divergent dynamics can arise solely from changes in mass distribution. Moreover, for certain parameters, billiards with unusual dynamics, including periodic billiards, are observed, which are conjectured to be nonexistent in standard billiards in Euclidean domains.

Summary: The droplet size and uniformity are important properties of water-in-oil emulsions. In this study, we used microchannel homogenization to prepare relatively monodisperse emulsions. The effects of emulsifier concentration, continuous-phase viscosity, dispersed-phase volume fraction, and operating pressure on droplet size and distribution were investigated. The results demonstrate the suitability of this method for preparing monodisperse emulsions.

Summary: This paper presents the first direct generation of orbital angular momentum (OAM) mode squeezed states using an optical parametric oscillator (OPO). The squeezing rates for the LG+10 and LG-10 modes are -5.4 dB and -5.3 dB, respectively. Additionally, OAM mode squeezed and entangled states are generated by manipulating the nonlinear process of the OPO through controlling the relative phase of two different mode beams. The generated Laguer re-Gaussian (LG) entangled states are characterized by indirect measurement of squeezing and direct measurement of entanglement between different LG modes. The effective manipulation of OAM quantum states offers new insights into the generation and construction of high-dimensional quantum information and quantum metrology.

Summary: This paper describes the design and characterization of miniaturized optofluidic devices for sensing, which integrates collimating optical fibers with custom microfluidic chips. Utilizing collimating graded-index fiber tips improves fiber-channel-fiber interfaces and reduces beam divergence and insertion losses compared to standard single-mode fiber. The optofluidic setup allows for absorption spectroscopy measurements with minimal solution volume and comparable sensitivity to traditional cuvettes, suitable for integration into compact lab-on-a-chip systems.

Summary: Thin films of BaFCl:Sm nanocrystals with a polymer binder were used to create fluorescence images. The films were exposed to UV-C light, resulting in the conversion of Sm3+ to Sm2+ ions and a large linear dynamic range. The red fluorescence of Sm2+ was read-out using blue-violet illumination and a laser scanning confocal microscope, with a resolution equivalent to 125 line pairs per mm or 6400 dpi for 16 greyscale levels. Higher resolutions could be achieved with collimated UV-C laser exposure or higher resolution photomasks. Ultra-high resolution binary fluorescence images with resolutions down to 2 μm (250 line pairs per mm, 12,700 dpi) were also created. The technology could have applications in anti-counterfeiting labeling.

Summary: Plasma-polymerized polyoxazoline (POx) thin films can be used as a fast and solvent-free method for electrode functionalization. This study investigated the effects of current exposure, extended incubation, and repeated electrode rinses on the stability of polymethyloxazoline thin films. The films were found to become more diffusive after incubation and rinse steps, and changes in nanotopography were observed after exposure to current, suggesting a change in the film structure.

Summary: This paper reports an optofluidic sensor for rapid detection of gas-phase analytes towards wearable colorimetric sensing. The sensor consists of a metal-insulator-metal thin-film structure integrated with a quartz micropillar array to improve the delivery of vapor analytes onto the sensing surface. Experimental results demonstrate that the micropillar array significantly reduces the sensor response time compared with conventional chamber experiments. The concentration-dependent response of the sensor confirms its potential for continuous, compact, and quantitative colorimetric analysis of volatile analytes in low-volume samples.

Summary: This paper presents a colorimetric sensing system for rapid detection of gas-phase analytes from flowing micro-volume fluid samples. The sensor platform combines an analyte-responsive metal-insulator-metal (MIM) thin-film structure with a large area quartz micropillar array, allowing precise alignment and separation of optical and fluidic structures. The sensor's response time is reduced from minutes to seconds, making it suitable for portable/wearable devices. The platform shows potential for continuous, compact, and quantitative colorimetric analysis of volatile analytes in low-volume samples.
