BACKGROUND Microleakage is still one of the defects of resin composites that can lead to treatment failure; and re-bonding technique is one of the effective ways to reduce it. This study evaluated the effect of re-bonding with a surface sealant or a dentin adhesive on microleakage in class V microhybrid, nanohybrid, and packable composite restorations. MATERIALS AND METHODS In this in vitro s...

Front Cover: In article number 2100222 by Rachel C. Steinhardt and co-workers, a soft actuation system is described, based on new core-shell thermally-expandable microparticle, made of isobutane core polystyrene shell, linked to photothermal nano-transducer, gold nanoparticles, resulting in core-shell-shell nanohybrid. The particles expand thermal milieus, are able power the movement composite ...

Long admired for informational role and recognition function in multidisciplinary science, DNA nanohybrids have been emerging as ideal materials for molecular nanotechnology and genetic information code. Here, we designed an optical machine-readable DNA icon on microarray, Avatar DNA, for automatic identification and data capture such as Quick Response and ColorZip codes. Avatar icon is made of...

Copper, the essential element required for human body is well-known its profound antibacterial properties, yet salts and oxides of copper metals in mine tailings are reported to be a big burden modern era. Among other oxides, CuO, particular, known have beneficial effects on humans, while slight nanoengineering viz., surface functionalization nanometer-sized oxide shown make some paradigm shift...

One of the long term goals of sending human beings to the Moon and the Mars is to stay there, for which temporary outposts and permanent bases must be constructed. Due to the tight constraint of space transportation capacity, it is highly desirable that the outposts and bases can be built by using locally harvestable resources, such as lunar soils. For instance, it is, theoretically, possible t...

A Ag/TiO2 nanocomposite, in which silver nanoparticles are highly dispersed in the uniformly sized pores of a cubic mesoporous TiO2 molecular-sieve film, has been fabricated.

In this study, a glycogen-gold nanohybrid was fabricated to enhance the potency of a promising hepatoprotective agent silymarin (Sly) by improving its solubility and gut permeation. By utilizing a facile green chemistry approach, biogenic gold nanoparticles were synthesized from Annona reticulata leaf phytoconstituents in combination with Sly (SGNPs). Further, the SGNPs were aggregated in glyco...

The present work reported on the synthesis and characterization of Poly-3-Thenoic acid/Cu-TiO2 nanohybrid (PCuT) for photocatalytic degradation organic azo dye pollutant from wastewater. as-synthesized by an in-situ modified sol-gel method including chemical oxidative polymerization was characterized X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, UV-visible diffuse re...
