Herein we present a highly sensitive sensing method combining amphiphilic molecules and wettability gradient photonic hydrogels for molecular recognition and chemical sensing applications. These wettability gradient photonic films exhibit low analyte amount, fast response, as well as interference resistance, which enable them for applications in forgery detection and visual determination of ana...

A series of mesoporous silica-based catalysts with finely-tuned surface wettability have been synthesized, of which the catalysis efficiency towards aqueous hydrogenations is highly dependent on their surface wettability and can be five times higher than that of the commercial Pd/C catalyst.

In the field of stone conservation, a very common direct intervention seeks to increase water repellence objects. By limiting interaction between solid and water, possibility alteration due action (liquid or solid) as well that related colonisation surfaces by organisms is reduced. To decrease wettability, chemicals are often applied create surface layer; however, laser texturing, currently use...

Smart water flooding (SWF) is a promising enhanced oil recovery (EOR) technique due to its economic advantages. For this process, wettability alteration the most accepted controlling effect that leads increased factors (RFs). The main objective of work investigate how relative permeability curves’ interpolant affects SWF mechanisms’ assessment. Wettability described by shifting these curves in ...

We describe a poreto reservoir-scale investigation of wettability variation and its impact on waterflooding. We use a three-dimensional pore-scale network model of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully predict experimentally measured relative permeability data for the water-wet case, and demonstrate that the model captures experime...

Surface wettability is one of most important indexes for understanding the interfacial characteristics between a solid surface and a liquid, especially such physico-chemical properties as hydrophilicity and water repellency. Recently, non-contact wettability assessment by monitoring the behavior of liquid covering a sample surface by jet-flow application to the liquid has been proposed. This me...

Silicon gravure patterns are engineered to have cells that are wettable and lands that are not wettable by aqueous inks. This strategy allows excess ink on the lands to be removed without using a doctor blade. Using an aqueous silica ink, continuous lines as narrow as 1.2 μm with 1.5 μm space are gravure printed.
