In the background material to his Nobel Prize talk in 2010, Prof. Geim illustrated the strength of graphene with his now famous cat hammock example : The unit hexagonal cell of graphene contains two carbon atoms and has an area of 0.052 nm2. That translates into a density of 0.77 mg/m2. A hypothetical hammock measuring one square meter made from graphene would thus weigh 0.77 mg.

According to the World Health Organization (WHO), cancer is the second leading cause of death globally with an estimate of 9.6 million deaths in 2018. Therefore, the development of new strategies for advancing cancer therapy and diagnosis are still extremely necessary in order to combat cancer diseases.

The ability to communicate new advances in science and technology has never been more important, and in that regard innovations with nanotechnology are growing more rapidly than ever with benefits to both society and the economy.

Certain areas of scientific research require atomically clean surfaces and low rates of contamination. In these instances, the ultra-high vacuum (UHV) environments are essential.

With the advancing of material science, nowadays the thin film deposition technology is developing quickly and has a crucial role in our everyday lives. Thin film deposition is the act of applying a thin film on the surface of another material. It is used in the manufacturing of devices such as computers and thin film transistors. It also finds applications in the production of semiconductors as well as in simple everyday objects as a typical household mirror.

Creating defect-free sheets of Graphene is said to be one of the main ‘hurdles’ in the search for wide scale commercialization of the material… but why is it so important to form large defect free sheets?
Graphene has received an astonishing amount of interest these past few years, so much so that now it is commonly referred to as the miracle material that’s predicted to revolutionize the 21st century.

Researchers from Virginia Tech’s Future Materials Laboratory and MInDS Laboratory have recently demonstrated that high-intensity focused ultrasound (HIFU) is a promising, non-invasive stimulus with multiple superior and unique capabilities to induce localized heating and achieve temporal and spatial thermal effects in polymers.

High-entropy alloys (HEAs), which are formed by combining nearly equal parts of several – usually five or more – primary metals, are an emerging class of advanced materials that hold great potential for creating materials with superior mechanical, thermal, and catalytic properties.
