DOI: 10.1002/smll.202207822
Abstract: Uniformly depositing a thin layer of functional constituents on porous foam is attractive to realize their concentrated interfacial application. Here, a simple but robust polyvinyl alcohol (PVA)-mediated evaporation drying strategy to achieve uniform surface deposition… read more here.

DOI: 10.1016/j.aca.2020.01.042
Abstract: Thioarsenicals, such as dimethylmonothioarsinic acid (DMMTAV) and dimethyldithioarsinic acid (DMDTAV), have been increasingly discovered as important arsenic metabolites, yet analysis of these unstable arsenic species remains a challenging task. A method based on surface-enhanced Raman… read more here.

DOI: 10.1016/j.apsusc.2018.10.261
Abstract: Abstract Amino functionalized surfaces were selectively modified via the combination of a wet agarose stamping technique and microcontact printing technique. Because of the specific reaction environments and diffusion of HNO2 confined in agarose stamp, the… read more here.

DOI: 10.1016/j.colsurfa.2021.126144
Abstract: Abstract The coffee ring effect (CRE) lies at the heart of droplet-based processing techniques where the drying process of the solute-laden droplet leads to the undesirable formation of a ring-like pattern with uneven distribution of… read more here.

DOI: 10.1016/j.jcis.2020.03.094
Abstract: The so-called coffee-ring effect (CRE) is extraordinarily common, problematic in industry and attractively puzzling for researchers, with the accepted rule that it requires two key-ingredients: solvent evaporation and contact line pinning. Here, we demonstrate that… read more here.
