Life as we know uses energy to reproduce itself. Organisms build and break down larger molecules using a common set of reactive intermediate energy carrier molecules. These carrier molecules help chaperone the reactions which build life's biochemical complexity and help push metabolic reactions to drive cellular reproduction. New research suggests that such compounds can be made easily in the environment in the absence of biology, providing a hint as to how life may have started.
CO¬2 capture from the air can mitigate further CO2 emissions, related increase in global temperature and climate change. Direct air capture of CO2 (DAC) is one of the promising ways for atmospheric CO2 extraction. In a new research paper, researchers propose CO2 capture from the air by membranes, which has been considered almost impossible for this challenging task.
Magnesium silicide (Mg2Si) is a thermoelectric material that can convert heat into electricity. Though it is known that adding antimony impurities enhances the performance of Mg2Si, the mechanisms underlying this effect are unclear. Now, scientists from Japan shed light on the effects of these impurities at the atomic level, taking us closer to arriving at a practical way of efficiently harvesting waste heat from cars and thermal power plants to produce clean energy.
Researchers at the Laboratory of Organic Electronics, Linköping University, have for the first time demonstrated an organic battery. It is of a type known as a 'redox flow battery', with a large capacity that can be used to store energy from wind turbines and solar cells, and as a power bank for cars. An article now published in Advanced Functional Materials.
DNA and proteins are two fundamental biochemical polymers found in all living cells. They are very different in terms of their molecular properties: DNA is a remarkably homogenous polymer in terms of its molecular properties, while proteins can be extremely heterogeneous with regard to these properties. New research suggests the intrinsic ways that DNA and proteins interact at molecular level can lead to extremely diverse behaviours that may helped shape important aspects of modern biology.
Whether in fitness, medicine or in the entertainment industry, IT devices worn on the body, such as smart watches, are becoming increasingly popular. Such wearables benefit from the input device fitting as naturally as possible to the body - for example as electro-sensitive fabrics, so-called e-textiles.
Researchers from St. Petersburg provided a unique experiment. They implanted a polymer scaffold as a vascular prosthesis into the rat abdominal aorta and monitored the process of its bioresobtion for 16 months. An artificial vessel was formed where the scaffold was located. It posess similar characteristics as a natural vessel.
Researchers at The University of Tokyo studied a new mechanism of gelation using colloidal particles. By delaying the formation of gel networks after rigid-cluster formation, the final structure had less mechanical stress, leading to new gel production methods.
Multilayered carbon material could be the perfect fit for heat management in electronic devices.
Researchers successfully print and demonstrate organic transistors, electronic switches, which can operate close to their theoretical speed limits. They showed high-speed operation only requires low voltages to work, which would reduce the power consumption of their applications. These kinds of transistors are used in display technology such as liquid crystal display (LCD) screens and e-ink. This is the first time this kind of transistor has been printed and it could lead to new curved, flexible and even wearable low power devices.
