    Manufacturing of stretchable substrate with biaxial strain control for highly-efficient stretchable solar cells and displays

    Abstract There has been significant research focused on the development of stretchable materials that can provide a large area with minimal material usage for use in solar cells and displays. However, most materials exhibit perpendicular shrinkage when stretched, which is particularly problematic for polymer-based substrates commonly used in stretchable devices. To address this issue, biaxial…

    Design of high bulk moduli high entropy alloys using machine learning

    Abstract In this work, the authors have demonstrated the use of machine learning (ML) models in the prediction of bulk modulus for High Entropy Alloys (HEA). For the first time, ML has been used for optimizing the composition of HEA to achieve enhanced bulk modulus values. A total of 12 ML algorithms were trained to…

    Unraveling Paddy Soil Secrets: Surprising Contribution of Nonmicrobial Mechanisms to CO2 Emissions

    Newswise — In a seminal study published recently in the journal Eco-Environment & Health, have shown that natural processes, especially reactions involving certain reactive oxygen species, play a big role in how paddy soils release CO2. This adds to our understanding of the world’s carbon balance. Researchers embarked on a journey to decode several aspects…

    Apparently Coyotes Can Climb Trees

    Recently, Moraga resident Stephanie Becker was washing dishes at home, when she saw, through the window, some branches shaking in her neighbor’s apple tree. They were shaking quite a lot—”much more than I was used to seeing from our backyard squirrels,” she says.  With neighbors and fences all around, she wasn’t expecting to see a…

    Scientists Created a Monkey With Two Different Sets of DNA

    The monkey “chimera” with two sets of DNA at three days old. Some body parts appear tinted green, because the researchers marked the transplanted cells with fluorescent dye to trace what parts they developed into. Cell / Cao et al. Researchers have created a monkey with two different sets of DNA by injecting stem cells from…
