Summary: This study investigates the influence of plasmonic resonance on carrier dynamics in perovskite solar cells by incorporating specially designed poly(3-aminothiophenol)-coated gold nanoparticles into the perovskite absorber. Through changes in the photophysical properties of the OIHP films, transient absorption spectroscopy, and density functional theory calculations, the research shows that plasmon excitation can fill trap sites at the grain boundary region and improve the device performance. The work provides clear evidence for plasmon-induced trap occupation in OIHP, suggesting that plasmonic nanostructures may be effective additives to enhance the efficiency of perovskite solar cells and thin-film solar cells in general.

Summary: This study demonstrated that Cu2O microparticles were rapidly dissolved to copper ions inside cells, followed by lysosome-mediated exocytosis. Smaller microparticles had a lower uptake rate but dissolved more quickly, leading to faster exocytosis activation. The rapid release of copper ions resulted in immediate toxic effects, mainly through necrosis, while glutathione buffering ability alleviated copper toxicity. The turnover of intracellular copper was much faster at sublethal exposure levels, but the labile copper(I) concentration only increased by a maximum of 2 times. Tolerance to copper-based nanoparticles depended on their ability to discharge released copper ions.

Summary: Daily temperature variations challenge the stability of halide perovskites in solar cells. However, by using the ordered dipolar structure of beta-poly(1,1-difluoroethylene), we were able to stabilize the perovskite black phase and improve solar cell performance. Our p-i-n perovskite solar cells achieved a record power conversion efficiency of 24.6% and retained high efficiency after exposure to various temperatures and thermal cycling.

Summary: This study investigated the toxic effects of silver, zinc oxide, and copper oxide nanoparticles on mouse mesenchymal stem cells. The results showed that these nanoparticles induced oxidative stress, lipid peroxidation, DNA fragmentation and oxidation, and increased sensitivity to apoptosis in the stem cells. The cell cycle was also affected, particularly by silver nanoparticles. These adverse effects should be considered when using nanoparticles in medical applications involving mesenchymal stem cells.

Summary: Fabric conditioners are colloidal dispersions of cationic double chain surfactants that self-assemble in vesicles. By reducing the content of these surfactants using hydrophilic biopolymers, products with lower environmental impact can be obtained without affecting their performance. The study focuses on the role of modified guar biopolymers on the physicochemical properties of the formulation, aiming to design sustainable home-care products.

Summary: In this feature article, the authors provide an overview of their research on using statistical copolymers as a coating material for metal oxide nanoparticles and surfaces. They develop a polymer-based coating platform that shares features with self-assembled monolayer and layer-by-layer deposition techniques. The synthesized copolymers containing phosphonic acid groups show strong affinity to metals and experimental evidence of colloidal stability of the coated particles. Applications in nanomaterials and nanomedicine are also discussed, including the beneficial effects of coatings on nanopowders, contrast agents, and stimuli-responsive particles.

Summary: Inhaled airborne particles smaller than 100 nm have been shown to deposit in the alveolar region of the lungs. The pulmonary surfactant lining the alveoli can be modified by interactions with inhaled nanoparticles, affecting pulmonary functions. This study evaluates the properties of a pulmonary surfactant substitute called Curosurf (R), which is used to treat respiratory distress syndrome in premature babies. The addition of alumina nanoparticles to Curosurf (R) alters its rheology, resulting in a sol-gel transition and suggesting potential toxicity associated with changes in lung fluid properties.

Summary: This study evaluates functionalized poly(ethylene glycol) (PEG) terminated with a single phosphonic acid, referred to as PEG(ik)-Ph, as coating agents for metal oxide surfaces to enhance the stability of sub-10 nm particles in protein-rich biofluids. The findings demonstrate that the one-step wet-chemical synthesis of cerium oxide nanoparticles (CNPs) with PEG(ik)-Ph introduces a core-shell structure with 3 nm cerium oxide cores and functionalized PEG polymers in a brush configuration as the shell. The coated CNPs show high Ce(III) content and increased colloidal stability in cell culture media, making them potentially suitable for nanomedicine applications. Additionally, the CNPs exhibit an additional absorbance band in the UV-vis spectrum in the presence of hydrogen peroxide, which indicates the formation of Ce-O-2 (2-) peroxo-complexes and suggests their potential catalytic activity for scavenging reactive oxygen species.

Summary: Under very high ionic strength conditions, the formation and dissociation of complexes are influenced by the ionic strength, with a specific critical threshold at 0.62 M triggering complex formation. Strong electrostatic interactions lead to the formation of aggregates that are difficult to dissolve, while weaker interactions result in easier dissolution but higher difficulty in re-dissociation.
