Summary: Cationization of cotton during mercerization positively affects trichromatic vat dyeing, resulting in uniform coloration when conducted with an epihalohydrin during the process. Shortening the reaction time to 5 hours with 3-chloro-2-hydroxypropyltrimethyl ammonium chloride (CHPTAC) can also improve efficiency. The change in charge upon cationization leads to high adsorption of vat-dye anions, significantly improving color depth and producing colors with higher chroma and targeted hue, particularly in trichromatic dyeing.

Summary: This study focused on the synthesis and characterization of SLGO phosphors doped with Bi3+/Eu3+, Bi3+/Tb3+, and Bi3+/Eu3+/Tb3+ ions. The crystal structure, site occupancy, and phase composition of the synthesized phosphors were discussed. The optical properties, PL mechanisms, and energy transfer processes were also investigated. The results showed that the synthesized phosphors have potential applications in the development of white light-emitting diodes (WLEDs).

Summary: This study introduces a varifocal liquid lens formed by electrowetting and dielectrophoretic effects, proposing a Maxwell force-driven liquid lens with a large aperture and low threshold voltage. By utilizing the polarization effect to generate Maxwell force, the threshold voltage decreases sharply with an increase in liquid volume, potentially expanding the aperture of the liquid lens to the centimeter level. The lens transitions from concave to convex as Maxwell force increases, showing promise for applications in light-sheet microscopes and virtual reality systems.

Summary: An ultrafast quantum state holography scheme based on the interference of photoelectron wave packets from multiphoton ionization was presented, utilizing trichromatic pulse sequences generated by a shaper. The hologram phase control is achieved by varying the relative phases of individual pulses in the sequence. This trichromatic shaper-based photoelectron holography scheme proves to be a powerful tool for time-resolved and phase-sensitive observation of ultrafast quantum dynamics, showing promising results in quantum phase analysis.

Summary: This paper proposes a new method to design arrays with minimum redundancy, which can significantly increase the virtual array aperture while keeping the size of the transmit and receive antennas the same. The application of this method to subarray-type antennas using multi-channel transceivers is described, along with the analysis of the final beam pattern and its benefits and limitations.

Summary: This study investigates the implementation of three different viscous effects modeling methods in hypersonic flow conditions. The methods are evaluated based on their capability to predict aerodynamic performance and their impact on the geometric design of a hypersonic passenger transport waverider. The results show that incorporating viscous effects reduces the aerodynamic efficiency of the waverider and increases computational time.

Summary: A one-dimensional mono-pulse microstrip antenna is essential for target detection, tracking, recognition, and imaging. However, the large size caused by feeding and coupling hinders miniaturization and integration. To address this issue, a miniaturized mono-pulse antenna with a compact size and good isolation is proposed.

Summary: In this study, hexagonal arrays of cell clusters were fabricated using self-assembled superparamagnetic cone structures. These structures effectively captured and arranged magnetically labeled cells, forming cell cluster arrays. By minimizing the system's total energy, the growth and migration of cells were restricted by the local magnetic field gradient caused by the hexagonal superparamagnetic cones.
