Summary: Silver doped magnesium (Ag:Mg) bimetallic nanoparticles were successfully synthesized for use in thin-film organic solar cells. The addition of these nanoparticles enhanced the photocurrent collection in the photoactive layer, leading to improved device performance. The highest power conversion efficiency (PCE) of 4.11% was achieved at a 1.5 wt% doping level, representing a 79% improvement compared to undoped cells. The localized surface plasmon resonance effect (LSPR) was identified as the key factor for enhancing optical absorption and charge transport processes in the solar cells.

Summary: This study focuses on improving the performance of all-small-molecule organic solar cells (ASM-OSCs) by designing and synthesizing novel donors with suitable crystallinity. It was found that the introduction of chlorine atoms enhances the crystallinity of blend films but also leads to larger phase separation and more defects, resulting in lower power conversion efficiency. On the other hand, donors with appropriate crystallinity exhibited smaller domain size, more suitable crystallinity, and improved exciton dissociation efficiency, charge transport efficiency, and carrier mobility.

Summary: We have witnessed significant progress in the design, optimization, and utilization of carrier particle systems for studying membrane proteins in near-native environments over the past decade. New and improved systems continue to emerge, pushing the boundaries of existing carrier systems, while specific carrier systems establish themselves as the preferred choice for certain types of target membrane proteins. This review covers the most commonly used carrier systems, highlighting their similarities and differences, as well as current trends and future directions in the field. Special attention is given to the biophysical properties and membrane mimicking ability of each system, and how they may impact the study of embedded membrane proteins and their structure or function.

Summary: A method is proposed to control the final morphology of roll-to-roll slot-die coated poly(3-hexylthiophene) (P3HT) by optically exciting the p-type polymer during coating. This study demonstrates the relationship between the morphology and physical properties of the thin film by combining density functional theory, molecular dynamics simulations, X-ray experiments, absorption spectroscopy, and THz spectroscopy. It is observed that P3HT films excited with light during deposition exhibit higher crystallinity, texture with more face-on orientation, and increased out-of-plane charge mobility.

Summary: In this study, protein-protein interactions in protein solutions were investigated using small angle X-ray scattering and molecular simulations. The results showed that as protein concentration increases, the balance between spatial and orientational correlations changes, and patchy interactions may occur. By analyzing experimental data and simulations, it was found that patchy interactions between proteins lead to dimer formation, and these dimers exist in an open conformation, maximizing hydrophobic attractions for inter-protein alignment.

Summary: Recent advances in protein expression protocols have allowed for the investigation of structurally complex and disordered biomolecules using small-angle scattering experiments. A modeling scheme has been developed that combines classical form factor based modeling with spherical harmonics-based formulation to accurately calculate scattering profiles from these complex samples. The scheme can account for flexible domains and other structurally elaborate components, and we demonstrate its utility through a case study on a growth hormone receptor membrane protein. We also explore how the scattering profiles vary under different contrasts and discuss the implications for data modeling.

Summary: This study investigates the nanostructure and electrical conductivity of ion beam deposited Pt for operando electron microscopy at elevated temperatures. It reveals that the microstructure of Pt remains stable up to around 800 degrees C and with an applied current density of approximately 100 kA/cm(2). The conductivity increases with temperature due to densification, while changes in the hydrocarbon matrix have less influence. Recommendations are provided for optimizing Pt deposition parameters to maximize stability and minimize electrical resistance.

Summary: We have successfully fabricated self-standing Samarium Doped Ceria (SDC) membranes and investigated their structure and ionic transport properties. The membranes were obtained by depositing a water-soluble sacrificial layer (Sr3Al2O6) on a SrTiO3 single crystal substrate, followed by the deposition of the SDC layer. The creation of a 2D self-standing membrane allowed for the determination of its transport and structure properties without interference from the substrate. Furthermore, the thin SDC single crystal membranes can be used to manipulate the electrical properties by applying compressive or tensile strain.
