Summary: This study explored the size, distribution, and fluidity of microdomains in a lipid bilayer containing phosphatidylinositol (PI), showing that PI-derived submicron domains hindered lipid diffusion. Furthermore, the PI-derived microdomain acted as a scaffold for protein adsorption during the two-dimensional assembly of a membrane deformation protein.

Summary: The study reported the formation of microdomains in a ternary lipid bilayer composed of PE, PC, and Chol, which functioned as specific fusion sites for proteoliposomes. By investigating the composition and mechanism of these unique microdomains in supported lipid bilayers, it was found that different types of PE affected the area fraction of microdomains and that the microdomains were rich in polyunsaturated PE and exhibited L-d-like phase. The association of eggPC and Chol resulted in microdomain formation by segregating polyunsaturated PE and facilitating Chol interactions in the hydrophobic core.

Summary: This study investigated the effects of PE unsaturation and double bond distribution on the formation of submicron domains in lipid bilayers. The results showed that submicron domains enriched with polyunsaturated PE increased in area fraction with higher PE concentration and unsaturation levels. The segregation of polyunsaturated PE from Chol-containing regions played a key role in the formation of these domains.

Summary: Supported lipid bilayers (SLBs) are artificial lipid bilayers used as cell membrane model systems. This study investigated the effect of electrostatic interaction between the substrate surface and the lipid bilayer on the composition of SLBs. It was found that the lipid composition in SLBs can be controlled by modulating the substrate-induced electrostatic potential.

Summary: Polyunsaturated lipids, a major component in cell membranes, have received less attention compared to other lipids. A recent study found that polyunsaturated phosphatidylethanolamine induces the formation of non-raft domains in lipid bilayers. In this study, the effects of polyunsaturated phosphatidylcholine on non-raft domain formation were investigated.

Summary: We have developed an optical microscope based on surface plasmon resonance (SPR) to observe the dynamics of potassium ion (K+) concentrations. By measuring the attenuated total reflection spectra, we confirmed that the ionophore chelation reaction changes the refractive index. We successfully observed the dynamics of K+ concentration change through the K+ channels inserted in the lipid bilayer.

Summary: The efficiency of fluorescence quenching by graphene oxide (GO) in supported lipid bilayers (SLBs) was controlled by the SiO2 layer fabricated using atomic layer deposition (ALD) method. Wide-field fluorescence observation showed that the ALD-SiO2 layer varied the fluorescence quenching with distance dependence expected from the equation of Forster resonance energy transfer. Fluorescence single molecular observation of dye-labeled lipids was achieved in SLB existing in the effective range of the quenching by GO. The difference in fluorescence intensity between the upper and lower leaflets of SLB due to their distance from GO was revealed by the quenching experiment.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: In this study, the time-dependent wave packet method was used to investigate the reaction channels and mechanisms of Ca+ + HD. The results show that the CaH+ + D reaction channel plays a primary role, which is consistent with experimental results. Complex forming and direct-abstraction reaction mechanisms exist in this reaction process.

Summary: The evaporation behavior of nanosized water aggregations on two-dimensional electroneutral solid surfaces with different surface polar unit densities was investigated. The results showed that the evaporation rate changes non-monotonically with the surface polar unit density, and the minimum evaporation rate is obtained when the surface has a modest surface polar unit ratio of 66.7%.

Summary: The geometric structure and electronic properties of transition metal M (M = Cu, Fe, Mn)-TiO2 (101) surface adsorbed by NO2 and N2O were calculated by density functional theory (DFT) and DFT + U theory. The results showed that the adsorption of NO2 and N2O on Mn and Fe atoms is more stable, and a large number of active electrons are formed around these atoms, facilitating the catalytic reactions.

Summary: In this study, carbon nanobracelets, which are cyclic molecules composed of alternating polycyclic regions and double carbon chains, were investigated using spin-polarized density functional theory. The results show that carbon nanobracelets with odd number of monomers exhibit distinct electronic energy levels, band gaps, and carbon chain deformation compared to those with even number of monomers.

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.

Summary: Drug-loaded cellulose diacetate (CDA) membranes were prepared using different compositions of mixed solvent. The microstructure and performance of the membranes were investigated, and a method to predict drug release properties was proposed. The results showed that the composition of the mixed solvent significantly affected the overall performance of CDA membranes, and the release rates of drugs were related to Δdelta and the intrinsic viscosity of CDA.
