In a paper published in
NANO, researchers from Hubei, China discuss the top-down and bottom-up strategies for the synthesis of Graphene quantum dots (GQDs). The respective advantages and disadvantages of these methods are summarized. With regard to some important or novel ones, the mechanisms are proposed for reference. In addition, the application of GQDs in biosensors is highlighted in detail.
At present, various top-down methods, such as oxidative cutting, hydrothermal or solvothermal reactions, electrochemical oxidation, ultrasonic-assisted or microwave-assisted process, chemical vapor deposition (CVD) have been reported to produce GQDs. Meanwhile, the bottom-up methods have been developed rapidly, which mainly include carbonization methods and stepwise organic synthesis. Owi ....

The road to future zero emissions demands a new form of ammonia production

E-Mail
A grant of approx. DKK 21 million (EUR 2.8 million) from the EU framework programme for research and innovation, Horizon 2020 will help a research team from the Department of Biological and Chemical Engineering at Aarhus University to lead a global collaboration aiming to develop new technologies to produce green ammonia.
In terms of volume, ammonia is today one of the ten most important chemicals manufactured globally. The substance is primarily used in the production of fertilisers for modern agriculture, but has lately been envisaged as an opportunity to reduce carbon footprint for other industries, for instance the marine sector.
However, ammonia production is currently far from sustainable and carbon-free. The primary method of producing the annual approx. 235 million tonnes of ammonia used the world over is the Haber-Bosch process, which was invented more than 100 years ago. ....

There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there are crucial problems to solve. An international research team led by Chalmers University of Technology, Sweden, has now developed concrete guidelines for how the batteries should be charged and operated, maximising efficiency while minimising the risk of short circuits. ....

Psoriasis is a chronic inflammatory skin disease characterized by erythematous (red) patches and plaques. In some patients, psoriasis may be associated with comorbidities such as arthritis, obesity, diabetes, cardiovascular diseases, hyperlipidemia, or depression. Psoriasis lesions can occur on the scalp and face, in addition to all other areas of the body, causing considerable physical discomfort and psychosocial trauma from the stigma surrounding appearance defects.
More than 90% of patients with psoriasis have what is called psoriasis vulgaris, which is characterized by plaques, and less than 5% have the other varieties: arthritic psoriasis, pustular psoriasis, and erythrodermic psoriasis. The most common treatments for mild to moderate plaque psoriasis are topical corticosteroids an ....

HOUSTON - (Jan. 19, 2021) - Carbon nanotube fibers are not nearly as strong as the nanotubes they contain, but Rice University researchers are working to close the gap.
A computational model by materials theorist Boris Yakobson and his team at Rice s Brown School of Engineering establishes a universal scaling relationship between nanotube length and friction between them in a bundle, parameters that can be used to fine-tune fiber properties for strength. ....
