Fluorescent imaging of latent finger-marks benefits from enhanced sensitivity, selectivity, and reduced reliance on instruments. The review focuses on the topical developments reported on small-molecule organic fluorophores which could be used to develop latent prints through powder, solution, and fuming approaches. These inexpensive luminophores extend wide emission profiles that span the visible spectrum to visualize the latent prints with exceptional resolution, free from any interference originating from the background surface. Further, the critical challenges and prospective scope for future research developments to improve the detection of latent fingerprints using small-molecule fluorophores are also discussed.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 1","pages":"117 - 147"},"PeriodicalIF":2.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-024-00991-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the color and microstructure of the bronze coatings were characterized using a camera, colorimeter and scanning electron microscope. The results showed that the PVA/PEGDA microgels loaded with Cys (PVA/PEGDA + Cys microgels coating) not only did not change the color and appearance of the bronze, but also adhered and bonded well to the bronze surface. Confocal microscopy confirmed the soft and self-healing properties of the PVA/PEGDA + Cys microgels coating. Electrochemical testing and analysis showed that the PVA/PEGDA + Cys microgels coating exhibited excellent corrosion inhibition performance, with a corrosion inhibition efficiency of as high as 95.66%. The compressive test shows that the PVA/PEGDA + Cys microgels coating has certain reinforcement properties for bronze. The complete removal of PVA/PEGDA + Cys microgels coating can be achieved by spraying ethanol solution, indicating the enormous potential of microgels coating in protecting corroded bronze artifacts in the short term.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"631 - 649"},"PeriodicalIF":2.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is increasing interest in the field of wood conservation in studying bio-polymers and bio-nanocomposite materials that have better characteristics and more compatibility with the wood components and, thus, are more likely to give positive long-term conservation outcomes. This article focuses on the preparation of organic–inorganic bio-nanocomposite thin film coatings from hydroxypropyl cellulose (HPC), cellulose nanocrystals (CNCs), and cerium nanoparticles (CeO<sub>2</sub>) applied using solution blow spraying to protect wood surfaces outdoors. The uniform coating of nanocomposites and the thin film formation of this novel bio-nanocomposite on the wood surface were characterized by SEM imaging. The FTIR spectra of the films show that not only do CNCs improve the stability of HPC against UV radiation, but adding CeO<sub>2</sub> nanoparticles further optimized the UV resistance of the bio-nanocomposites. ATR analysis of treated wood surfaces shows a decrease in the formation of hydroxyl groups due to photooxidation for both HPC/CNC treatments and the organic–inorganic bio-nanocomposite HPC/CNCs/CeO<sub>2</sub> NPs. These results were also verified by colorimetric analysis. The UV–Vis spectra of the bio-nanocomposites showed that they absorb primarily in the UV-A and UV-B regions. Furthermore, the band gap was narrowed by adding CeO<sub>2</sub> NPs to the HPC matrix, leading to thin films with enhanced UV resistance.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 2","pages":"691 - 701"},"PeriodicalIF":2.3,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, none of the cycles accurately predicted the rank order of rutile TiO<sub>2</sub> grades for Florida gloss retention, nor the magnitude and direction of color fade in organic pigment/inorganic pigment blends. This paper follows up on these earlier studies, to examine whether the ASTM D7869 cycle might nevertheless have some utility for industry standard or specification purposes, across resin lines. We report for the first time the results of two recent studies comparing ASTM D7869 and South Florida weathering, for a range of weatherable binder chemistries commonly used in industrial coatings, and specifically examining color-matched, non-white colors. The data suggest that ASTM D7869 testing for 5000–6000 h might be a promising way to gauge the weatherability of coatings intended to meet 5-year South Florida weathering requirements. At the same time, the data also suggest that the ASTM D7869 cycle would be unreliable for predicting the weatherability of coatings intended to last 10 years or even much longer, within a 6–12-month timeframe, due to issues with false positives. For this reason, in the new SSPC Paint 47 fluoropolymer topcoat standard, a more aggressive UVB-313 fluorescent cabinet cycle was chosen, due to its ability to give results in 6 months, with a very low level of false positives.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"22 1","pages":"461 - 469"},"PeriodicalIF":2.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
