Intriguing low frictional properties of 2D materials can be harnessed for thin-film lubrication in small-scale devices by making their mechano-adaptive coatings. Herein, the reduced graphene oxide-polystyrene (rGO-PS) nanocomposite synthesized single-step chemical processing oxide and polystyrene is applied to prepare self-lubricating thin film over silicon substrate. The non-covalent π-π inter...

Damage to peripheral nerves often cannot be repaired by the juxtaposition of the severed nerve ends. Surgeons have typically used autologous nerve grafts, which have several drawbacks including the need for multiple surgical procedures and loss of function at the donor site. As an alternative, the use of nerve guidance channels to bridge the gap between severed nerve ends is being explored. In ...

Studies on the effect of substrate temperature on the modification process of a thin layer of polystyrene samples deposited on glass by using spin coating technique have been conducted. The polystyrene thin film surface was modified by using nitrogen plasma generated in a vacuum reactor by a capacitive plasma generator with a frequency of 40 kHz. The substrate temperature was set by variation o...

A sensor based on surface plasmon resonance (SPR) of plasmonic crystals fabricated via a colloidal-crystalassisted templating method is studied. Plasmonic crystals are prepared by depositing a thin gold (Au) layer onto a twodimensional array of polystyrene spheres self-assembled on a quartz substrate. The enhanced transmission as a result of the SPR of Au plasmonic crystals, which are immersed ...

A method is developed for calculating the small-angle x-ray scattering originating from within the interior of a thin film under grazing incidence illumination. This offers the possibility of using x-ray scattering to probe how the structure of polymers is modified by confinement. When the diffuse scattering from a thin film is measured over a range of incident angles, it is possible to separat...

The interface between skin and electrodes plays a major role in the accuracy efficiency of biopotential measurements. For reliable biosignal recording, stable low-impedance contact is required target tissue. Conventional wet (Ag/AgCl) are composed metal with skin-adhesive hydrogel. However, for long-term measurement, direct pre-gel electrode causes discomfort irritation, especially infants peop...

polymer/clay nanocomposites are considered as a new subject of research in iran and the world. addition of a minimum amount of clay (2-5wt%) can improve the mechanical properties, enhance barrier properties and reduce flammability dramatically. polystyrene (ps) exhibits high strength, high modulus and excellent dimensional stability, but it has poor ductility, elongation, and flexural modulus. ...

Front Cover: In article number 2100383, Ana-Maria Resmerita and co-workers show that incorporation of 5 wt% polystyrene/hydroxypropyl-β-cyclodextrins (HPβCD) semi-rotaxane into a polyethylene glycol/HPβCD crosslinked matrix leads to hydrophobic porous film with enhanced swelling ability thermal dielectric properties as compared those the pure material.
