Machine Learning assisted computational discovery of two-dimensional energy storage materials

2D-electrode-materialResearchers developed a holistic approach, which predicts both Li-ion storage and supercapacitive properties and hence identifies various important electrode materials that are common to both devices, may pave the way for next-generation energy storage systems. By leveraging the big-data generated by the computational pipeline, the team trains crystal graph-based machine learning models and demonstrates how this data-driven model could be helpful for the rapid discovery of potential materials from other databases.

The future of learning: Cambridge Advance Online meets bionanotechnology

Cambridge_Advance_OnlineBeing a relatively young field, Bionanotechnology is often neglected within undergraduate and postgraduate curriculum. With an increasing number of researchers and professionals of different backgrounds coming into the field, there is a clear need to have learning platforms that cover techniques, strategies and methods that characterise the design of bionano structures. In September 2021, Cambridge Advance Online, a new educational initiative created between the University of Cambridge and Cambridge University Press and Assessment, launched a 6-week online course about Bionanotechnology: Bionanotechnology from Theory to Practice.

Nanotechnology strategies for plant genetic engineering

genetic_engineeringThe development of plant genetic engineering lags behind the development of animal genetic engineering. Plant cells differ from animal cells in several aspects, a major one being that, in addition to the cell membrane, they possess a wall surrounding them to provide mechanical and structural support. In recent years, breakthroughs in nanotechnology for genetic engineering have provided more favorable tools for the genetic transformation of plants. A review summarizes the types of gene carriers used in plant genetic transformation, the ways of combining with foreign genes, and the differences and advantages compared with earlier traditional transgenic methods.

Cotton, PLA-phytochemical encapsulated nanofiber-based face mask for combating the spread of COVID-19 infections

facemaskAn estimated 6.8 billion face masks are used around the world each day, which ultimately are incinerated, sent to landfills or simply dumped in the environment, providing a glimpse of a forthcoming severe global environmental crisis. Many of these synthetic face masks are non-biodegradable in nature. To address this issue, researchers have developed a 3-layered biodegradable, antibacterial, breathable, herbal-extract based, and needleless electrospun face mask.

From aptamer-graphene interaction understanding to biosensor performance improvements

biosensorThe use of graphene-based field-effect transistors is one of the most powerful biosensing units for the detection of numerous biological and biochemical analytes. In new work, researchers propose a microscopic model of mycotoxin detection via graphene-based aptasensors enabling improvement of biosensor sensitivity, which is based on the investigation of aptamer interaction mechanism with graphene channel during binding of targeted molecules. The limit of detection is estimated at only 1 pM and time response in just 10 seconds, making the developed platform a high-performance device.
