AIM This study evaluated the effect of filler existence in self-etch adhesive resin on the marginal leakage of a class V restoration. MATERIALS AND METHODS Class V cavities were prepared and restored with a resin composite on the buccal surfaces of 48 premolars lined with unfilled or filled adhesives (n = 24). After thermo cycling, teeth in each group were divided to two subgroups (n = 12), s...

In order to improve the acid-resistant property of papermaking grade precipitated calcium carbonate filler and to obtain modified filler in powder form, sodium silicate/zinc chloride based modifiers were used in filler modification, and the use of modified filler in papermaking of deinked pulp derived from recycled newspaper was also preliminarily investigated. Under the preliminarily optimized...

Environmental concerns and the positive aspects of biowaste materials gained attention researchers to use them as filler in fabricating green composites along with polymer matrices, but most are not suitable for extensive applications high thermal applications. In natural particulate having ability fight against pathogens. To overcome such barriers, a modification biowaste—orange peel powder (O...

Silver has long been employed as an electrically conductive component, and morphology-dependent properties have been actively investigated. Here we present a novel scalable synthesis method of flower-shaped silver nanoparticles (silver nanoflowers, Ag NFs). The preferential affinity of citrate molecules on (111) surface of silver enabled spontaneous anisotropic growth of Ag NFs (bud size: 250~5...
