Additionally, Schiff base is employed as an N, N-donor ligand to regulate the shape of NPs. The effective production and stability of the nanocomposite were validated by extensive morphological (SEM, TEM, and XRD), thermal (TGA and DTG), and spectroscopic (UV-visible, FTIR, NMR, and fluorescence) investigations. DTQ@AgNPs acts as a dual-mode chemosensor for the sensitive and selective colorimetric detection of Zr⁴⁺ and fluorometric detection of Cd2⁺ ions with detection limits of 0.80 and 0.69 µM, respectively. The successful detection of Cd2⁺ in actual water samples with excellent recovery rates and low relative standard deviations has confirmed the practical application of the suggested sensor DTQ@AgNPs. Furthermore, the fabricated test strips enabled rapid, on-site colorimetric detection of Zr⁴⁺, demonstrating field-level usability. The nanocomposite DTQ@AgNPs also displayed significant antimicrobial activity against Escherichia coli and Pseudomonas aeruginosa, suggesting promising biomedical relevance. Its significance in biological systems is further supported by the detection of Cd2⁺ in the presence of BSA protein.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70360"},"PeriodicalIF":3.3,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines bio-based surfactants-particularly alkyl polyglucosides, rhamnolipids, and mannosylerythritol lipids-as sustainable options for cultural heritage preservation. Performance analysis shows promising but variable results across different applications. Alkyl polyglucosides demonstrate effective soil removal on calcareous stones, while rhamnolipids work well on organic materials when proper pH conditions are maintained. Knowledge transfer from the pharmaceutical and cosmetic industries provides valuable insights, though heritage-specific validation remains limited. The main challenges include inconsistent testing methods across studies, the need for substrate-specific optimization, and concerns about residue retention in porous materials. Rather than completely replacing conventional surfactants, the evidence suggests a more selective approach based on specific cleaning requirements. Future research should focus on developing standardized testing protocols for heritage applications, conducting long-term studies on material compatibility, and adapting quality control frameworks from established industries. Successfully transitioning to sustainable surfactants will require carefully balancing environmental benefits with proven conservation effectiveness, ensuring that green alternatives meet the rigorous demands of cultural heritage preservation.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70355"},"PeriodicalIF":3.3,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to slight cell constant differences between cubes and rhombic dodecahedra, synchrotron X-ray diffraction (XRD) patterns verify size-related peak shifts especially for rhombic dodecahedra. The cubes also show peak asymmetry that can be fitted with bulk and surface layer lattice components. Fast fourier transform (FFT) of high-resolution transmission electron microscopy (HR-TEM) images reveal greater lattice point deviations in the area near the particle surfaces. The lattice disturbance and cell constant changes produce size and facet effects in their band gaps. Despite very low photocatalytic hydrogen evolution yields, cubes are moderately more active than rhombic dodecahedra in this reaction. However, rhombic dodecahedra exhibit a stronger piezoelectric response, and are piezocatalytically more active than cubes toward rhodamine B (RhB) degradation. These phenomena should be linked to their internal lattice variations.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70364"},"PeriodicalIF":3.3,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphological characterization (HR-TEM, SEM-EDS) confirmed the anatase phase of TiO2 and the atomic dispersion of metal-integrated CDs on its surface. UV-vis DRS and XPS analyses revealed a marginal red shift in band-gap and the presence of sp2-hybridized graphitic carbon, and metal-carbon interactions, indicating enhanced light absorption and charge separation through Schottky junctions. Under direct sunlight illumination, Pd-CD/TiO2 thin film exhibited superior hydrogen yield (1167 µmol g-1 h-1) and maintained stability over 25 h, outperforming Ni-CD/TiO2 (494 µmol g-1 h-1) and bare TiO2 (166 µmol g-1 h-1) photocatalyst thin films. Concurrent glycerol oxidation at neutral pH (pH∼7) yields glycolaldehyde (41% selectivity), formic acid, and dihydroxyacetone as value-added products. Enhanced photocurrent density and lower impedance of Pd-CD/TiO2 corroborate improved charge carrier separation and dynamics.

The carbon scaffold was derived from CO2 reduction through sodium borohydride (NaBH4), enabling the simultaneous incorporation of boron and oxygen. This eco-friendly strategy converts CO2 into a hierarchically porous structure with the phosphoric acid treatment. The resulting PCDC exhibited a large surface area and pore volume, enabling effective sulfur loading and rapid lithium-ion transport. Structural analyses confirmed the presence of both B and P within the carbon matrix, with B contributing to enhanced electrical conductivity and P forming catalytically active configurations such as C3PO and C2PO2. Electrochemical testing revealed that PCDC accelerates polysulfide redox reactions, reduces charge transfer resistance, facilitates Li2S nucleation, and outperforms the CO2-derived carbon (CDC) without phosphorus doping. It delivered a capacity of 800 mAh g-1 for 100 cycles at 0.2C and showed around 600 mAh g-1 after 100 cycles at 0.5C.

A key molecular mechanism underlying LLPS of nucleic acids involves G-quadruplex (G4) structures of DNA and RNA interacting with intrinsically disordered proteins, particularly arginine and glycine (RGG/RG) rich proteins. The role of arginine residues in LLPS has been studied extensively, whereas few studies have focused on the role of the another frequently occurring residues, glycine. Here, we systematically investigated the contribution of G residues by substituting them with alanine (A), proline (P), valine (V), and tyrosine (Y) residues, generating a series of RX repeat peptides. Turbidity and microscopy assays with DNA oligonucleotides forming G4, duplex, as well as random coil, showed that RP and RA-peptides enhanced LLPS with G4 DNA, by comparing RG-peptide. In contrast, RY promoted liquid-solid phase separation (LSPS) with the G4 DNA, although it underwent LLPS with the random coil and duplex DNAs. In addition, RV-peptide formed aggregates even in the absence of any DNA. These results demonstrate that side-chain size, hydrophobicity, and aromaticity are critical factors for the LLPS and LSPS capability and selectivity with DNA forming various secondary structures. This study provides mechanistic insights into protein-nucleic acid LLPS and LSPS and guides the rational design peptides to undergo LLPS but not LSPS with nucleic acids.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00805"},"PeriodicalIF":3.3,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
