Bacterial biofilms are a major cause of harm related to medical infections and biofouling. Thus, 80% total caused by biofilm-forming microorganisms. Consequently, knowledge biofilm formation stages is crucial develop effective treatments prevent their in implants, tools, devices. For this purpose, quartz crystal microbalance (QCM) sensors becoming good alternative analytical methods for the rea...

In recent years, a wide range of different methods to implant nanosized patterns on surfaces have been developed. Spin coating immiscible binary polymer blends is a straightforward method to prepare micro- and nanostructures on thin films. This study utilizes binary blends to effortlessly prepare stable, surface-functionalized cellulose films. Blends of trimethylsilyl cellulose (TMSC) majority ...

In this study, a simple method for synthesizing graphene layer directly on quartz crystal microbalance (QCM) using laser was developed. This laser-induced (LIG) used sensing surface to simultaneously measure changes in the adsorbed mass, film stiffness, and electrical resistance during water adsorption. The developed LIG-QCM is convenient because its fabrication process free of any tedious mask...

The short-range order in water and ice was determined from experimentally measured partial radial distribution functions by applying the Quasi Crystalline Model (QCM). Partial were analyzed for at several pressures temperatures, crystalline ice, three known phases of amorphous ice: Low-Density Amorphous (LDA), High-Density (HDA), Very-High-Density (VHDA). It found that low temperatures pressure...

Abstract To meet the need for oil-compatible friction modifier additives that can significantly reduce energy consumption in boundary-lubrication regime, a macromolecular design approach has been taken. The aim was to produce lubricious polymer film on sliding surfaces. A series of readily functionalizable block copolymers carrying an oleophilic poly(dodecyl methacrylate) and poly(pentafluoroph...

Block copolymers of poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) and poly(oligo(ethylene glycol) methyl ether methacrylate) (POEGMA) with varying block sizes were synthesized by consecutive reversible addition-fragmentation chain transfer (RAFT) polymerization and then exposed to cellulose substrates with different anionic charge density. The extent and dynamics of quaternized PDMAEMA-b-...

Sum frequency generation vibrational spectroscopy (SFG) and quartz crystal microbalance with dissipation monitoring (QCM-D) are employed to study the interfacial structure and adsorbed amount of the amino acids L-lysine and L-proline and their corresponding homopeptides, poly-L-lysine and poly-L-proline, at two liquid-solid interfaces. SFG and QCM-D experiments of these molecules are carried ou...
