Front Cover: In article number 2100079 by Kailiang Ren and co-workers, a MoS2-g-PMMA/PI (MPP, PI is polyimide) nanocomposite consisting of thin layer poly(methyl methacrylate) coated 2D MoS2 nanosheets reported. The energy density MPP-3% (3% MoS2) reaches 8.6 J cm−3. Furthermore, the highest 3.92 cm−3 at 150 °C, which 47.9% higher than that film.

We report direct observation of a "Pac-Man" like coarsening mechanism of a self-supporting thin film of nickel oxide. The ultrathin film has an intrinsic morphological instability due to surface stress leading to the development of local thicker regions at step edges. Density functional theory calculations and continuum modeling of the elastic instability support the model for the process.

The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

On-demand, local delivery of drug molecules to target tissues provides a means for effective drug dosing while reducing the adverse effects of systemic drug delivery. This work explores an electrically controlled drug delivery nanocomposite composed of graphene oxide (GO) deposited inside a conducting polymer scaffold. The nanocomposite is loaded with an anti-inflammatory molecule, dexamethason...

nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. the better mechanical properties can be obtained ...

The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite filmfor food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorablefactors such as biodegradability and abundance in the world, therefore in this study, it was preparedchitosan-Ag nanocomposite with antibacterial properties for food packaging b...

Glucose and lactate enzyme electrodes have been fabricated through the deposition of an anionic self-assembled monolayer and subsequent redox polymer/enzyme electrostatic complexation on gold substrates. These surfaces were functionalized with a negative charge using 11-mercaptoundecanoic acid (MUA), followed by alternating immersions in cationic redox polymer solutions and anionic glucose oxid...
