Optimising Lubricant Oils to Boost Engine Efficiency | Ken Hope
About this episode
The engine of a typical passenger vehicle is made up of hundreds of mechanical parts. These parts require lubrication to prevent them from overheating and to keep them working efficiently. Ken Hope and his team at Chevron Phillips Chemical, headquartered in Texas, have analysed the extent to which different types of lubricant oils reduce friction. They then used this data to estimate how an optimised oil mixture can achieve an overall improvement in engine efficiency.

Our intestines contain millions of bacteria, known as our microbiota, which secrete compounds and play a key role in keeping us healthy. These bacteria don’t just affect the health of our digestive system, they can influence organs as far away as the brain. Dr Francesca Ronchi at Charité Universitätsmedizin in Berlin is determining the role of the microbiota in the prevention and development of neurological disorders.
The perspectives and characteristics of specific historical periods are often reflected in the literary texts produced and circulated at the time. Dr Andrea Binsfeld, an Associate Professor at University of Luxembourg, has conducted several studies examining narratives of slavery in ancient texts, including novels and political discourses. Her analyses outline, from a different perspective, the deep impact that the institution of slavery had in Greek and Roman societies.
Dr Lars Oddsson | The walk2Wellness Trial: Measuring the Impact of a Wearable Sensory Prosthesis on People with Peripheral Neuropathy
Dr Lars Oddsson, CTO of RxFunction and Adjunct Professor at the University of Minnesota is co-inventor of a wearable device called Walkasins® to help improve balance and reduce the risk of falls in people with sensory peripheral neuropathy. The walk2Wellness trial incorporated five clinical sites where they demonstrated that by replacing sensory stimulation for balance, this prosthetic device can have a positive impact on clinical mobility outcomes and quality of life for those who have suffered nerve damage causing loss of sensation in their feet.
The Hilbert space formulation is a central idea in quantum theory, but the ideas used by physicists to interpret the formulation widely differ. Furthermore, concepts in quantum mechanics are very abstract to those outside the field. Professor Inge Helland from the University of Oslo approaches these problems through what he calls ‘conceptual variables’, which belong to the minds of one or more conscious observers. From this basis, he achieves a new derivation of the Hilbert space formulation, which he hopes will lead to more satisfying studies of the foundations of quantum theory.
