Concurrent synthesis of nitrogen-doped carbon dots for cell imaging and ZnO@nitrogen-doped carbon sheets for photocatalytic degradation of methylene blue
Zinc oxide (ZnO) is a commonly used photocatalyst for degrading toxic organic dyes like methylene blue (MB) from water sources. The degradation efficiency of conventional graphene-based ZnO composites is, however, limited by their poor solubility. In a study published in the Journal of Photochemistry and Phot..

Mercuric ion capturing by recoverable titanium carbide magnetic nanocomposite
Heavy metals, like mercury, can have serious adverse effects on human health and on the environment. Their removal from wastewater has therefore become a priority. While adsorbents are being successfully employed to achieve this task, they have several limitations. To overcome these limitations, scientists ha..

Progress on nanostructured electrochemical sensors and their recognition elements for detection of mycotoxins: A review
Fungal toxins, also known as mycotoxins, can bring about a range of deleterious effects in humans. The detection of mycotoxin contamination in food for humans and feed for livestock has thus been an important area of research. The use of nanostructured electrochemical sensors and biosensors for detection of m..

Laparoscopy-assisted versus Open D2 Distal Gastrectomy for Advanced Gastric Cancer
Dissection of the D2 lymph node is standard treatment for advanced gastric cancer, done through either the open or laparoscopic approach. Laparoscopy-assisted distal gastrectomy (LADG) is widely used for the treatment of early-stage gastric cancer. A new randomized controlled trial reveals that LADG is a feas..

Heterogeneous activation of persulfate by reduced graphene oxide–elemental silver/magnetite nanohybrids for the oxidative degradation of pharmaceuticals and endocrine disrupting compounds in water
The contamination of water with pharmaceutical and organic compounds presents a serious health hazard. Scientists have now created reduced graphene oxide-based silver and magnetite nanohybrids that can activate peroxydisulfate to bring about the degradation of these contaminants. These nanocatalysts show good..
