Introduction At present, graphene, as the thinnest, strongest, and most conductive new nanomaterial known, has a promising development prospect recognized by many scientists. As Frank Wilczek, who won the Nobel Prize in Physics in 2004, said: “Graphene may be the only instance from quantum theory to application.” Graphene-based electrochemical biosensors have significant application value in … Read more
This article proposes a high-resolution multidirectional sensor that operates under low strain. Using a laser direct writing method, a porous graphene electrode is prepared on a PI/PDMS composite film, successfully creating a cross-shaped sensitive layer. The sensor exhibits excellent sensing performance, linear response, and repeatability. The unique sensing characteristics of the cross-shaped structure enable the … Read more
This article employs a simple fiber laser direct writing (fLDW) process to produce flexible graphene sensors embedded with MO nanoparticles. fLDW is an integration of various printing processes into a single step. This singular process effectively synthesizes graphene, optimizes the properties of carbon structures through functionalization, enables doping and hybridization, and deposits metal oxide nanoparticles. … Read more
As the most widely available energy source on Earth, the solar radiation reaching the Earth’s surface each year is immense, and it can be directly developed and utilized without geographical limitations. Therefore, solar energy is a promising emerging renewable energy source that can replace fossil fuels. Typically, solar power generation converts sunlight into electrical energy … Read more

An international team led by scientists at the Max Planck Society in Germany has recently developed a type of microbot that can rapidly remove pollutants and heavy metals from industrial wastewater. After recovery and treatment, these pollutants can be recycled, promising an efficient and economical method for wastewater purification. According to reports, heavy metal pollution … Read more
Indium oxide (In₂O₃) is an effective electrocatalyst for converting carbon dioxide (CO₂) to formic acid (HCOOH), but its inherent poor conductivity limits the effective charge transfer during the reaction process. Additionally, the aggregation of indium oxide particles during synthesis further restricts the exposure of active sites. This study addresses these issues by utilizing the template … Read more
Background Introduction In 2004, Geim and Novoselov et al. first isolated a monolayer honeycomb network of graphene based on sp2-hybridized carbon atoms from graphite using mechanical exfoliation. Since then, due to its unprecedented physicochemical properties, such as high specific surface area (the theoretical specific surface area of monolayer graphene is 2630 m2 g-1), excellent thermal … Read more
Indium tin oxide (ITO) is often used as a transparent conductor to control the pixels of touch screen displays; however, there has been an increasing number of alternative nano-materials emerging recently. For instance, carbon nanotubes, silver nanowires, and graphene have become candidates for this application industry. Recently, researchers at the University of Sussex in the … Read more
The touch screen is no longer a new term; it can be used in smartphones, wearable devices, smart homes, and many other electronic consumer products. When talking about touch screens, one cannot ignore the material ITO. Chemically, ITO stands for Indium Tin Oxides, which is doped tin oxide. It is a transparent conductor commonly used … Read more
