Summary: This study achieved in situ reversible tuning of CID in single AuNRs by controlling the CID process using CB[7]-based host-guest chemistry, paving a new route for efficient hot-electron photochemistry and biosensing applications. The nuclear magnetic resonance experiments confirmed the release of guest molecules from host-guest inclusion complexes in single CB[7]-NH2@AuNRs after encapsulation and release processes. In addition, competitive release of guest molecules and replacing them with competitor guests demonstrated the potential for in situ reversible tuning of CID in the same AuNR.

Summary: Dual-emissive photoconvertible fluorophores (DPCFs) are useful for tracking labeled cells in bioimaging. The directed photooxidation-induced conversion (DPIC) mechanism allows efficient DPCFs to be obtained by conjugating a coumarin to aromatic singlet-oxygen reactive moieties (ASORMs). Pyrrole is a suitable ASORM that provides a high hypsochromic shift and fast conversion. By modifying pyrrole, we can tune the photoconversion properties of the DPCFs, leading to an improved dual emissive converter, SCP-Boc, with high brightness and a 63% enhanced photoconversion yield. SCP-Boc was successfully used for sequential cell photoconversion using laser scanning confocal microscopy.

Summary: Current biomedical applications of nanocarriers focus on controlled drug delivery, but this study proposes a different approach where toxic molecules are extracted from biological tissues using lipid nanoemulsion (NE) droplets. By designing a highly lipophilic amine (LipoAmine), cargo-aldehydes can be reacted and encapsulated inside lipid NEs through dynamic covalent chemistry. The formation of imine conjugates was validated and the NEs successfully extracted fluorescent dye and toxic aldehydes from cells, demonstrating the potential for developing detoxification platforms.

Summary: This study investigates the influence of membrane curvature on Ca2+ binding to phospholipid bilayers using molecular dynamics simulations. The results show that Ca2+ ions preferentially bind to the concave surfaces of both zwitterionic and anionic bilayers. The membrane curvature also leads to significant changes in binding, including differences in ion concentrations, lipid coordination distributions, and binding patterns to different chemical groups of lipids. The effects of curvature differ between the concave and convex monolayers, and charge scaling is found to reduce Ca2+ binding to curved phosphatidylserine bilayers.

Summary: This study investigates the mechanism of ice nucleation by ice-nucleating proteins (INPs) using molecular dynamics simulations. The hydration layer around the ice-nucleating surface of an INP is found to be highly ordered, with slower dynamics compared to a non-ice-binding protein. The ice-binding surface of INP shows more evident ordering of the hydration layer compared to an antifreeze protein. The structural synergies observed in the INP make it a better template for ice nucleation than AFP, although both efficiently bind to the ice surface.

Summary: Researchers have developed a screening platform to identify SARS-CoV-2 mutants with enhanced ACE2 binding abilities. They found four mutations (F490K, S494K, G504F, and P499L) that formed stable complexes with more hydrogen bonds and salt-bridge interactions with ACE2. Simulation data suggests that these mutations allosterically alter the packing of the RBM interface, resulting in significantly higher rupture force for RBD-ACE2 contacts.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
