Summary: Engineering of the interface between perovskite absorber thin films and charge transport layers has significantly advanced perovskite solar cell (PSC) technology. The use of self-assembled monolayers (SAM-HTLs) as hole transport layers has led to almost lossless contacts, improving power conversion efficiency. This study demonstrates the successful vacuum-based evaporation of carbazole-based SAM-HTLs, which exhibit comparable performance to solution-processed counterparts, and also improves perovskite wetting and fabrication yield.

Summary: Controlling the dimension of nanostructures self-assembled from short peptides remains a challenge, with peptide bolaamphiphiles forming nanotubes due to the interplay between side chain structure and hydrophobicity; changes in amino acid side chain structure can significantly impact nanostructure formation, with the introduction of hydroxyl groups alleviating steric hindrance.

Summary: In this study, a single-molecule self-assembled layer of an aromatic organophosphonic acid (2PACz) is used to modify the cathode interface layer in inverted organic solar cells (OSCs). The modified OSCs show improved power conversion efficiency (PCE) and enhanced air stability. The strategy of using 2PACz as a modification material provides a new approach for constructing high-performance non-fullerene OSCs with enhanced air stability.

Summary: Conventional wisdom suggests that self-assembled alkylthiolate monolayers on gold are not stable when exposed to complex fluids such as raw serum at body temperature. However, this study demonstrates that these monolayers can last for at least 1 week under such conditions and can provide significant value for continuous electrochemical aptamer biosensors.

Summary: The properties of lipid monolayers at the interface between two immiscible electrolyte solutions have been studied extensively due to their biological relevance and potential to control ion and electron transfer across cellular membranes. Electrochemical characterization techniques have shown that lipid depletion and presence influence the intermixing of the two liquid phases at the nanoscale level. This study represents the first neutron reflectometry-electrochemistry investigation of ITIES, offering new possibilities for bioelectrochemical characterization and scattering based techniques at the liquid-liquid interface.

Summary: This article presents a prototype of a ferroelectric tunnel junction (FTJ) based on a self-assembled monolayer (SAM) of small, functional molecules. The SAM is highly uniform and thin, and exhibits reversible conductance switching. Compared to inorganic material-based FTJs, this approach using SAMs of small organic molecules allows for a higher level of functional complexity while maintaining a robust and simple fabrication process. The technology is expected to find applications in information storage and processing.

Summary: In this study, the plasmonic response of self-assembled monolayer silver nanoparticles was comprehensively investigated using various computational and experimental techniques. The Fano resonance and SERS application were studied, and it was found that the higher-energy antibonding mode is not only from the antibonding dipole-dipole mode, but also from the antibonding quadrupole-quadrupole mode and hybridized magnetic mode. The effects of dimer gap and size were discussed in detail, and a two coupled oscillators model was used to illustrate the mechanism of the Fano resonance.

Summary: The stable electrochemical potential window of thiolate self-assembled monolayers (SAMs) on Au, Pt, and Cu electrodes is studied systematically in aqueous electrolyte systems. The reductive stability is found to depend on the binding strength of sulfur and competitive adsorption of hydrogen, while the oxidative stability is related to each surface's propensity toward surface oxide formation. The stability of SAMs is also influenced by factors such as SAM defects, intermolecular interactions, SAM thickness, and the ability to directly oxidize or reduce the non-sulfur part of the SAM molecule.

Summary: Protein adsorption at interfaces is important in biology and biotechnology, but not fully understood due to complex forces controlling it. By adding trivalent salt, it is possible to manipulate the protein-resistant properties of certain SAMs, providing new insights into protein-surface interactions.

Summary: The organic synaptic phototransistor (OSPT) is a critical component for next-generation neuromorphic computing, offering advantages in computing in memory and large-scale parallel processing. However, the challenge lies in achieving effective charge transport in the organic semiconductor layer. In this study, a self-assembled monolayer (SAM) of octadecyltrichlorosilane (ODTS) is used to modify the surface property between the pentacene channel layer and the biocompatible polyvinyl alcohol (PVA) electret, significantly improving the hole mobility and ON-OFF ratio of OSPT by an order of magnitude. The OSPT demonstrates a large memory window and effective modulation of synaptic weight, with improved recognition accuracy in digital image recognition.
