Summary: Recent research has shown that low-dimensional materials, such as quantum dots and core-shell quantum dots, exhibit strong nonlinear optical behavior and have potential applications in photo-electronics, photovoltaic nonlinear optics, light-emitting diode fabrication, and laser protections. Variations in core-shell shape and size, as well as the chemical composition of quantum dots, define their enhanced nonlinear optical properties. Specific nonlinear optical properties, such as nonlinear refraction, optical limiting, saturable absorption, and reverse saturable absorption of CdTe and CdSe quantum dots, along with core-shell quantum dots and their applications, were assessed in this study.

Summary: In this study, photoluminescence and polarized reflection spectra were investigated in quantum well structures with symmetric and asymmetric barriers. The phenomenon of light birefringence was observed in structures with asymmetric barriers, which was attributed to the lower symmetry of the interfaces compared to the bulk crystals. The discussion about this phenomenon is presented.

Summary: The formation of CdTe quantum dots with transferrin reduced Cd release and cytotoxicity, primarily through hydrophobic interaction. Structural and conformational changes in transferrin were attributed to nanoeffects of CdTe QDs rather than released Cd. This study is significant for understanding the biocompatibility of Cd-QDs and their toxicity mechanisms at the molecular and cellular level.

Summary: This study investigates the morphology transition of peptide self-assembly and finds that shifting the position of the terminal residue can achieve the transition from nanofibers to nanotubes. The underlying mechanism is revealed, and it is found that the formation of giant nanotubes with a bilayer shell structure is promoted by inter-molecular C-terminal H-bonding. This morphological transformation method is applicable to other analogues and provides a convenient approach for predicting peptide nanostructures.

Summary: Amino acids are bio-building blocks that play various roles in metabolic activities. Supramolecular structures formed by amino acids exhibit amyloid-like characteristics, which are driven by hydrogen bonds and play critical roles in the properties and applications of amino acid assemblies. Tyrosine-based superstructures have diverse properties and functions, making them promising next-generation biomaterials for biomedical applications. However, modulating the energetically stable supramolecular structures of tyrosine-based organizations is challenging. By assembling L-Y and D-Y, the secondary structures of the supramolecular assemblies can be modulated, leading to distinct organization kinetics and modulation of physicochemical properties.

Summary: Efficient separation and migration of photogenerated charge carriers are crucial for enhancing photocatalytic performance. In this study, a novel IOBi2WO6/Bi2O3 S-scheme heterojunction with an inverse opal structure was prepared using a hydrothermal technique followed by calcination. The IOBi2WO6/15Bi2O3 heterojunction exhibited the highest photocatalytic hydrogen evolution activity, reaching up to 312.56 mol g-1h-1, which was significantly higher than that of pristine Bi2WO6 (32.15 mol g-1h-1) and IOBi2WO6 (92.15 mol g-1h-1). The apparent quantum efficiency of the heterojunction was 8.9% at 420 nm. The enhanced photocatalytic activity was attributed to the synergy between the formation of the Bi2WO6/Bi2O3 S-scheme heterojunction and the construction of the inverse opal structure. The mechanism and driving force of charge carriers' transfer and separation were investigated and discussed using density functional theory calculation. This study provides a promising approach for preparing efficient charge carriers' separation and migration heterojunction photocatalysts for practical applications.

Summary: In this study, two new surfactant-like peptides (SLPs), named (IA)4K and (IG)4K, were developed for selective delivery of antisense oligodeoxynucleotides (ODNs) and small interfering RNA (siRNA) to cancer cells. The interaction of the peptides with nucleic acids, their transfection efficiency, and cytotoxicity were investigated. Both SLPs showed high transfection efficiency and selectivity for cancer cells, and exhibited low cytotoxicity. This study provides insights into the structural features required for nucleic acid complexation and delivery, and serves as a guide for the design of new SLPs for selective gene delivery to minimize adverse effects in healthy tissues.

Summary: In this study, an artificial peroxidase was fabricated through the co-assembly of two types of short peptides and hemin. The coordination between hemin and the peptide nanofibers preserved the handedness of the nanofibers. The chiral selectivity of the artificial peroxidases towards D- and L-DOPA substrates was determined by the conformation of histidine residues and the handedness of the peptide nanofibers.

Summary: This study shows that short peptides containing L-form aromatic residues form left-handed nanofibrils, while those containing D-form aromatic residues assemble into right-handed ones, regardless of the chirality of their C-terminal hydrophilic residue. The stacking of aromatic side chains between ss-strands directs the twisting direction of the ss-sheets formed, and more ordered and stronger aromatic stacking facilitates the formation of nanofibrils with a marked tubular feature. This research bridges the knowledge gap in our understanding of how aromatic residues affect the supramolecular chirality of short peptides.

Summary: Air injection is a promising method for increasing the recovery efficiency of light crude oil. This study investigated the oxidation behavior and interactions of SARA components during low-temperature oxidation (LTO) of two light crude oils from the Xinjiang oilfield under air and nitrogen atmospheres. The results showed that oxidation under air greatly affected crude oil stability at temperatures above 150 degrees C. The asphaltene component exhibited the highest oxidative activity, leading to the introduction of more oxygen and further oxidation of C-O groups and sulphoxides on the asphaltene surface. These findings provide valuable insights into SARA component oxidation and interactions during LTO, which can be applied in future air injection techniques.

Summary: This study examined the chiral self-assembly of multicharged surfactant-like peptides using a series of short peptides with different combinations of L-lysine and D-lysine residues. The results showed that specific combinations of residues led to the formation of nanofibers or nanoribbons with left-handed chirality. Molecular simulation indicated that the orientation of the single β strand determined the supramolecular chirality, and the presence of glycine or isoleucine residues affected the conformation and handedness of the assemblies. This study provides insights into the mechanism of chiral self-assembly of short peptides and may contribute to the regulation of chiral molecular self-assembly.
