This article details the different types of fingerprints, the broad range of surfaces, and various development techniques available for on-site latent fingerprint collection, with fingerprint fidelity being of prime significance. 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}

Furthermore, an evaluation of the in vitro cytotoxicity and release study, water absorbency, stiffness, and tensile properties were conducted. The incorporation of plant extract into fabric was confirmed through scanning electron microscopy and Fourier transform infrared spectroscopy analysis. The findings of the investigation revealed that a fabric treated with 10% <i>R. prinoides</i> leaf extract exhibited inhibition zones of 8.2 mm against <i>S. aureus</i> and 6.75 mm against <i>E. coli</i>, whereas 10% <i>C. macrostachyus</i> leaf extract treated fabric showed inhibition zone of 5.4 and 2.42 mm, respectively. Fabrics treated with concentrations lower than 10% of the extract in an in vitro study exhibited nontoxic effects, leading to an increase in cell viability rates for both plant extracts. After 48 h, treated fabrics exhibited a release of 73.3%, 75.9%, and 81.8% for <i>R. prinoides</i> leaf extract and 58.3%, 66.1%, and 77.8% for <i>C. macrostachyus</i> extract treated with 3%, 5%, and 10% concentrations, respectively. Furthermore, the plant extract treated fabrics showed an improvement in water absorbency and fabric stiffness.

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}

In order to identify the chemical responsible for paint craters, a technique that is extremely surface sensitive, chemically selective and capable of imaging is required. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) perfectly fits all these analysis requirements, and for the past decade we have used ToF-SIMS to identify automotive paint cratering chemicals.
