Scientists develop new model of electric double layer
Credit: CC0 Public Domain The new model takes into account a wide range of ion-electrode interactions and predicts the charge storage capacity of the device. The model’s theoretical predictions are consistent with the experimental results. Data on electric double layer (EDL) behavior can help develop more efficient supercapacitors for portable electronics and electric vehicles. The study was published in ChemPhysChem.…

Scientists demonstrate advanced low-coherence BOCDR system using periodic pseudorandom modulation
This figure shows the results of distributed strain sensing over a length of approximately 100 m of optical fiber utilizing BOCDR with periodic pseudorandom modulation. The diagram above shows the structure of the sensing fiber, which includes two tightly wound 47-meter sections and a 10-centimeter taut section near the end. The middle plot shows the distributed Brillouin frequency shift along…

Scientists uncover origins of horse riding from human remains
The kurgan hypothesis claims that the Yamnaya people spread their culture across Eurasia, including by building burial mounds like this kurgan in the Mongolian steppes. Credit: William Taylor As anyone who has ever ridden a horse knows, riding a horse is hard on the body, but does it change the way your skeleton looks? The answer is “complicated,” according to…

Scientists review 7,000 studies on microplastics, and their startling conclusions are a warning to humanity
Credit: Unsplash/CC0 Public Domain It’s been 20 years since the journal Science published a paper showing the accumulation of tiny plastic fragments and fibres in the environment, particles that the journal dubbed “microplastics”. This paper opened up an entirely new field of research, and since then, over 7,000 studies have been published demonstrating the pervasiveness of microplastics in the environment,…
