Although food quality standards have improved dramatically, outbreaks of foodborne illnesses are still common. Luckily, we have one line of defence to exploit: antibacterial food packaging. Dr Kay Cooksey of Clemson University is leading ground-breaking research to overcome the hurdles associated with antibacterial food packaging, bringing it one step closer to market.
Kevin R. Supak | Tapered LADs: Acquiring Cryogenic Liquid Propellants in Deep Space
To carry out complex manoeuvres such as orbit insertion, large spacecraft on long voyages must carry tanks of liquid propellants, kept at ultra-cold temperatures. In existing designs, however, heat leaking into these tanks can form unwanted vapour bubbles in the channels required to extract their contents – which are especially difficult to remove in the microgravity environment of deep space. In their research, a team at the Southwest Research Institute presents a simple solution to this problem – through which the sides of these extraction channels are tapered, allowing vapour bubbles to escape. Results from recent microgravity testing of this technology could lead to exciting new opportunities for future space missions.
Dr Alessia Besford | Understanding the Crown of a Nanoparticle
Medical nanoparticles are an innovative method of delivering drugs to highly specific locations in the body, such as tumours or across the blood-brain barrier. Once a nanoparticle has entered the bloodstream, it forms a crown of surrounding biomolecules called a corona. The composition of this corona depends on its biological environment and the material of the nanoparticle itself and it has significant implications for how the nanoparticle interacts with the human body. Dr Alessia Besford from the Leibniz Institute of Polymer Research Dresden studies these interactions and how they can be refined to develop more effective medical nanoparticles.
Dr John Slough | Fuelling the Next Generation of Rockets with Nuclear Fusion

Professor Rui Martins | Building a Microelectronics Research Group from the Ground Up
Microelectronics are the minuscule components that power our modern world, from your smartphone to the systems that keep jet airliners in the sky. These essential components, such as transistors, resistors, capacitors, and inductors are the building blocks of microchips – the tiny computing units that process vast quantities of binary information. However, the world around us isn’t binary. Engineers must develop ways to translate between the analogue world that we inhabit and the binary world of chips. Over the last 30 years, Professor Rui Martins of the University of Macau has built a world-renowned research lab – the State Key Laboratory of Analog and Mixed-Signal VLSI – focused on further bridging the gap between analogue and digital.
Yiqiao Yin | Tracking Deforestation with Neural Networks
Forests are key to Earth’s biodiversity and the global ecosystem, hosting 80% of the planet’s plant biomass and two-thirds of all mammal species. However, they are also in decline; each year, around five million hectares of woodland are lost to logging and wildfires. Tracking this loss is essential to controlling and mitigating deforestation, but this requires careful interpretation of satellite imagery. Yiqiao Yin, Kieran Pichai, Benjamin Park and Aaron Park have developed a model to automatically identify forests from these images. Their new approach is already showing huge promise.
Yiqiao Yin | Seeing Deep into the Lungs with Deep Learning
X-rays and other forms of medical imaging let doctors peer into the body, revealing the internal structure of organs and tissues without invasive surgery. Doctors use the results to identify abnormalities such as broken bones, diagnose diseases such as cancer, or even monitor the health of a foetus within the womb. Although this technology is remarkable, the images aren’t useful in isolation. Experts must analyse the resulting data and parse what is healthy or unhealthy from the noise. Yiqiao Yin, Jaiden Schraut, Leon Liu and Jonathan Gong have created new machine learning technologies to support that crucial interpretation, focusing on X-rays and lung health.

Steve Schmalz | An Innovative Circuit Breaker for Renewable Power Grids
A key step towards a carbon-neutral future could be reached through dispersed power grids, featuring networks of local-scale renewable energy and battery storage plants. To prevent these power grids from damaging themselves and their surroundings when electrical faults arise, they must be integrated with ‘circuit breakers’, which temporarily interrupt the current flowing through them. However, currently available circuit breakers cannot handle the medium-voltage direct currents best suited for these grids. Through an innovative new circuit breaker design, Steve Schmalz and his colleagues at Eaton Corporation, the Illinois Institute of Technology (IIT), Virginia Tech and the National Energy Technology Laboratory (NETL), hope that this challenge will soon be overcome.
