The phenomenon of acid mine drainage represents a major source of environmental pollution, prompting the need for innovative solutions to minimize and address this.

The article describes the mechanical behaviour of PVB interlayer and the constitutive models by which the polymer can be represented under different load cases.

The smallest antenna in the world was made from DNA 20,000 times smaller than human hair. Learn more about its use cases.

The high share of buildings in energy consumption and carbon dioxide emission has led researchers to seek techniques to reduce energy consumption in this sector. In this study, considering a hot and arid climate region, the wall's heat gain was investigated. To reduce energy demand, three techniques of adding PCM, combining absorption chiller with a solar system and dispersing nanoparticles were used and the results were evaluated transiently. In July, the addition of PCM to the building's walls reduced the heat exchange between interior and exterior spaces up to 21%. To cool the inter...

 E-Mail The human heart contracts about 70 times per minute, while that of a rat contracts over 300 times; what accounts for this difference? In a new study publishing 10th June in the open-access journal PLOS Biology, led by Michael Geeves and Mark Wass of the University of Kent and Leslie Leinwand from the University of Colorado Boulder, reveal the molecular differences in the heart muscle protein beta myosin that underly the large difference in contraction velocity between the two species. Myosin is a "molecular motor" - an intricate nanomachine that forms the dynamic core of a muscle's ...
