A brief review of graphene–metal oxide composites synthesis and applications in photocatalysis
Changyuan Hu, Tiewen Lu, Fei Chen et al. · 1 Mar 2013
Graphene is a flat monolayer of carbon atoms with perfect sp2-hybridized two-dimensional carbon structure. Its fascinating high conductivity, superior electron mobility, extremely high specific surface area and easy functionalization make graphene a good substrate to produce graphene-based composites. Especially, graphene–metal oxide composites have attracted extensive attention for their potential applications in environmental and energy-related areas.…
Development of new hybrid<i>Phoenix pusilla</i>/carbon/fish bone filler reinforced polymer composites
S. Abhishek, Sanjay Mavinkere Rangappa, Raji George et al. · 2 Oct 2018
Designing new eco-friendly fibers enable the creation of an alternative resource for many applications, specifically within the field of polymeric composites. This article details the fabrication of hybrid epoxy composites comprising natural fiber, Phoenix pusilla plant dry leaves which belong to the family of date palm and nanofillers made from the fish bones, which has…
Sources, distribution, and health effect of carcinogenic polycyclic aromatic hydrocarbons (PAHs) – current knowledge and future directions
Vaneet Kumar, N.C. Kothiyal, Saruchi Saruchi et al. · 12 Sep 2016
Polycyclic aromatic hydrocarbons (PAHs) are chemical compounds containing two or more fused benzene rings in linear, angular or cluster arrangement, consisting of only carbon and hydrogen. Polycyclic aromatic carbons (PACs) include the unsubstituted hydrocarbons (PAHs) and substituted PAHs (e.g. nitro-PAH, oxygenated PAH). PAHs are the most stable form of hydrocarbons having low hydrogen-to-carbon ratio and…
Progress on electrochemical sensors for the determination of heavy metal ions from contaminated water
Xiangzi Dai, Shuping Wu, Songjun Li · 3 Apr 2018
With the development of modern industry, heavy metal pollution is increasingly becoming the focus of government and citizen concern around the globe. Some heavy metals such as Pb, Hg, As, Cr and Cd are highly toxic and hazardous to the human health due to their non-biodegradable nature even at lower levels of exposure. Therefore, it…
Synthesis of <i>Gum tragacanth</i> and acrylic acid based hydrogel: its evaluation for controlled release of antiulcerative drug pantoprazole sodium
Saruchi Saruchi, Balbir Singh Kaith, Rajeev Jindal et al. · 3 Apr 2014
In this work, natural polymer was used as matrix for preparing hydrogel to improve the performance of the material in biomedical sector. Gum tragacanth and acrylic acid [Gt-cl-poly(AA)] based hydrogel was prepared by graft copolymerization of natural Gum tragacanth with acrylic acid using ascorbic acid–potassium persulfate as an initiator and glutaraldehyde as cross-linker. Synthesized hydrogel…
