Summary: The concept of plasmonic hotspots is central to nanophotonics, specifically in surface-enhanced Raman scattering (SERS). SERS signals from single molecules often exhibit fluctuations, challenging the concept of static hotspots. Recent experiments have shown SERS intensity fluctuations (SIFs) to occur over a wide range of timescales due to various physical mechanisms causing SERS and the dynamic nature of light-matter interaction. This study presents a high-speed acquisition system that captures SERS spectra with microsecond time resolution, revealing that high-speed SIF events occur with relatively equal probability over a broad spectral range.

Summary: This study achieves record spatial resolution in ambient tip-enhanced photoluminescence (TEPL) from CdSe/ZnS semiconductor quantum dots by taking advantage of surface roughness at the apex of a sputtered plasmonic gold probe. The reproducibility of observations is demonstrated using different plasmonic probes and samples. The high spatial resolution in TEPL is attributed to field enhancement at the metal tip-fluorophore interface.

Summary: A single-molecule spectroscopic method with micro-electron volt energy and submolecular-spatial resolution has been developed to induce molecular luminescence in scanning tunneling microscopy. The state-selective characterization of energy levels and linewidths of individual electronic and vibrational quantum states of a single molecule has been demonstrated. Tuning energy levels of molecular systems through the Stark effect and plasmon-exciton coupling in the tunneling junction opens up possibilities for creating designed energy-converting functions.

Summary: Researchers have developed a facile method of fabricating a non-uniform SERS substrate using an annealed thin gold film. This substrate offers multiple resonances and gap sizes within the same sample, and shows reproducible trends in terms of geometry and plasmonic response. It can be used for fast screening of analytes due to the lateral variation of the resonances within the same sample.

Summary: Mass spectrometry-based proteomics is a powerful technology for quantifying proteins in cells or tissues. Single-cell transcriptomes are influenced by stochastic noise due to low transcript numbers, whereas single-cell proteomes appear to be more complete. With the combination of imaging and spatial transcriptomics, the spatial organization of cells in tissues can be studied alongside ultra-sensitive proteomics.

Summary: The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel that regulates salt and fluid homeostasis across epithelial membranes. Alterations in CFTR cause cystic fibrosis, a fatal disease without a cure. In this study, the authors investigate the structure and function of CFTR, specifically focusing on the dimerization of its nucleotide-binding domains (NBDs) and the allosteric gating mechanism that regulates chloride conductance. They also explore the effects of disease-causing substitutions on NBD dimerization and propose implications for potential clinical therapies.

However, there are uncertainties regarding the geographical and vertical distribution of microplastics, and without efforts to overhaul plastic production and waste management practices, the abundance and radiative forcing of airborne microplastics will continue to rise.

Summary: This study assesses the calcification physiology of five cool temperate coralline algae in response to different irradiance levels and finds that the enhancement of calcification rates is limited to lower irradiances. The study also suggests the existence of two calcification strategies and indicates that magnesium incorporation is determined by the magnesium to calcium ratio in the calcifying fluid.

Summary: Lattices of exciton-polariton condensates are used to study and implement non-Hermitian bosonic quantum systems. The authors introduce polaromechanical metamaterials, which are arrays of traps confining light-matter polariton fluids and phonons. A strong polariton-phonon interaction induces a time-dependent inter-site polariton coupling, leading to asynchronous locking of light fluids from neighbor sites at the energy detuning. These results provide a platform for coherent control of dissipative quantum light fluids with hypersound.

Bridging the two fields can lead to tunable and enhanced optomechanical couplings and explore non-linear many-body optomechanics. Coherent vibrations in polariton resonators introduce time modulation and enable access to Floquet physics and optomechanically induced non-reciprocal phenomena.

Summary: In this study, a thin-shell approximation is developed for the Mie scattering problem in a spherical multilayer structure with radially anisotropic dielectric functions. This approximation simplifies the numerical calculations and is applicable to the calculation of optical absorption in each individual layer. Experimental results demonstrate that the thin-shell predictions show excellent agreement with the full solution for experimentally relevant parameters, suggesting that this approximation can be utilized as a substitute to speed up numerical implementation and simplify analytical developments.

Summary: Recent research has shown that the mean path length of rays inside refractive objects under Lambertian illumination is not independent of the medium's scattering strength, particularly in the case of zero scattering. Trapped ray trajectories play a crucial role in creating an unexpected discontinuity from zero to low scattering. This study provides alternative analytic results for the mean path length of simple refractive shapes under zero scattering conditions.

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.
