Summary: This study presents a modified microfluidic method for creating Giant Unilamellar Vesicles (GUVs) containing lyotropic nematic liquid crystals. By combining spontaneous de-wetting and buoyancy, octanol droplets and GUVs can be separated effectively. The simplified device and increased formation rate make it easier to produce larger quantities of GUVs, but the phase behavior of lyotropic liquid crystals is sensitive to concentration.

Summary: Plastic waste is a global problem due to inadequate recycling capabilities. A potential solution is the upcycling of polyolefins into valuable products. This study examined the activity of silica-alumina catalysts for the conversion of polyethylene into aromatic compounds at temperatures below 280°C. The catalysts showed comparable yields to Pt/Al2O3 catalysts and the product selectivity could be controlled by altering reaction conditions or the acid site density of the catalysts. These catalysts can be reused without regeneration and their activity improves with each recycling event.

Summary: Topological insulators are bulk insulators with metallic and fully spin-polarized surface states exhibiting Dirac-like band dispersion. By using spin-resolved photoemission spectroscopy, we show that the topological surface states of a topological insulator interfaced with an antimonene bilayer exhibit nearly full out-of-plane spin polarization within the substrate gap. This phenomenon is connected to a symmetry-protected band crossing of the spin-polarized surface states. The nearly full out-of-plane spin polarization of the topological surface states occurs along a continuous path in the energy-momentum space, and the spin polarization within the gap can be reversibly tuned from nearly full out-of-plane to nearly full in-plane by electron doping. These findings pave the way for advanced spintronics applications that exploit the giant out-of-plane spin polarization of topological surface states.

Summary: Heteroprotein complex coacervation is a phenomenon triggered by the interaction between oppositely charged proteins, resulting in two liquid phases in equilibrium. In this study, the complex coacervation between type A gelatin (GA) and native and thermal treated 8-lactoglobulin (8-lg and 8-lg (TT)) was investigated. The thermal treatment led to changes in the surface properties of the proteins, but had minor effects on their aggregation state and lutein binding ability. The optimal condition for the complex coacervation was determined, and the obtained coacervates showed high lutein entrapment efficiency.

Summary: This study reports the direct observation of in situ tunable valley-selective Hall effect and demonstrates the control of geometric phase of electrons using an out-of-plane electric field. The researchers used high-quality bilayer graphene and circularly polarized midinfrared light to observe the optically induced valley population and found a significantly larger valley-selective Hall effect compared to molybdenum disulfide. By monitoring the valley-selective Hall conductivity, the researchers studied the evolution of Berry curvature with bandgap.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
