Fast-charging, long-running, bendy energy storage breakthrough

(University College London) A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed and demonstrated by UCL and Chinese Academy of Sciences researchers.

Energized by enzymes — nature’s catalysts

(DOE/Pacific Northwest National Laboratory) Scientists at Pacific Northwest National Laboratory are using a custom virtual reality app to design an artificial enzyme that converts carbon dioxide to formate, a kind of fuel. PNNL’s Wendy Shaw and Aaron Appel organized a session at the 2020 #AAASmtg and invited colleagues from across the nation to share what they’ve learned.

Car sharing innovation and impact: Comparing European cities

(Politecnico di Torino) While waiting for the publication of the toolkit for local decision-makers, expected by the summer, some European case studies analyzed in the STARS project are presented in Bremen

Longstanding flaw in sensor readings could lead to heating and cooling design errors

(Princeton University, Engineering School) Standard comfort measurements used to design heating and cooling systems share a common flaw, according to new research. The researchers said the error was caused by the standard instrument used to measure thermal effects of radiant heating and cooling. The instrument and associated formulas used to calculate comfort based on the sensor’s readings do not properly account for air flow called free convection. The failure led to temperature errors of over two degrees Celsius.

Leaking away essential resources isn’t wasteful, actually helps cells grow

(University of Tokyo) Experts have been unable to explain why cells from bacteria to humans leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites — substances involved in the chemical processes to sustain life with production of complex molecules and energy — may provide cells both selfish and selfless benefits.

Something from nothing: Using waste heat to power electronics

(University of Tsukuba) Researchers from the University of Tsukuba developed an improved thermocell design to convert heat into electricity. The thermocell contained a material that exhibited a phase transition from one arrangement of atoms to another when heated to 50 °C. The phase transition caused the output voltage of the thermocell to increase substantially to a level sufficient to power electronics. This thermocell shows promise as a way to use waste environmental heat to power electronic devices.

Researchers virtually ‘unwind’ lithium battery for the first time

(The Faraday Institution) An international team led by researchers at UCL has revealed new insights into the workings of a lithium battery by virtually ‘unrolling’ its coil of electrode layers using an algorithm designed for papyrus scrolls.
