Shen Wang and Professor Feng Hao from the Systems and Security theme at the Department of Computer Science and their collaborator from Durham University, have had the paper ‘Anti-Counterfeiting for Polymer Banknotes Based on Polymer Substrate Fingerprinting’, published in the journal IEEE Transactions on Information Forensics and Security, in which they propose a novel technique called Polymer Substrate Fingerprinting, which can identify each banknote’s own unique, unclonable fingerprint.

The researchers have found that every polymer banknote has a unique "fingerprint", which is caused by the inevitable imperfection in the physical manufacturing process, whereby the opacity coating, a critical step during the production of polymer notes, leaves an uneven coating layer with a random dispersion of impurities in the ink. This imperfection results in random translucent patterns when a polymer banknote is back-lit by a light source.

Ever more new hadrons are being observed at the LHC, including several unexpected discoveries of tetraquark and pentaquark states.

Applications are invited for an Associate Professor or Professor of Infection Microbiology to join the School of Life Sciences at the University of Warwick.

The School of Life Sciences has an international presence in microbiology, particularly within the global research priority of antimicrobial resistance (AMR). We aim to appoint an outstanding new academic staff member to strengthen research in cross-disciplinary approaches, complementing existing strengths in the School and leading a laboratory based research group in one or more of the following areas: antimicrobial resistance, anti-infective discovery, host-pathogen interactions and immunology including the microbiome, microbial genetics, virology and structural and chemical biology approaches to address human and animal infection.

Closing date: 11 April 2021

WMG Associate Professor Dr Mel Loveridge, and Principal Engineer Martin Dowson, have authored a special Faraday Insight entitled “Why Batteries Fail and How to Improve Them: Understanding Degradation to Advance Lithium-Ion Battery Performance,” a key consideration as we transition to a fully electric future.

It is part of a collection, of pieces from leading UK battery experts, published by the Faraday Institution. The Faraday Insights are evidence-based assessments of the market, economics, commercial potential, and capabilities for energy storage technologies. The insights are concise briefings that aim to help bridge knowledge gaps across industry, academia, and government.

The briefing addresses key requirements in lifetime, performance and safety needed for LIBs to continue to lead electrification in multiple sectors, and explains why, to achieve this researchers need to better understand – and find ways to mitigate – the many causes of battery degradation.
