Most analytical methods in biology require invasive procedures to analyze samples, which leads to irreversible changes or even their destruction. Furthermore, the sensitivity of such approaches often stems from the averaging of signals generated by a large number of cells, making it impossible to study the underlying heterogeneity of responses.
Harvesting energy from walking human body Lightweight smart materials-based energy harvester develop
Specifically, the device can capture biomechanical energy from the motion of the human knee and then convert it to electricity which can be used to power wearable electronics such as pedometers, health monitors, and GPS. This work has been published in Applied Physics Letters and recommended as a featured article by editors.
Self-driving cars have become better and more reliable in recent years. Before they might be allowed to drive completely autonomously on our roads in the near future, however, a few hurdles have to be taken. Above all, the need to assess the surroundings at lightning speed and to recognize people and obstacles takes current technologies to its limits.
Scientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) are developing a technology for printing the electrodes for miniature li-ion batteries by an inkjet printer. The ongoing research may help to create power supplies for biosensors, wearable electronics, and other miniature devices.
Coral reefs around the world are threatened by pan-tropical bleaching events that occur when the surrounding sea water temperatures increase due to ongoing climate change and extreme conditions like El Nin?o. However, patterns of bleaching occurrence can be very difficult to predict, especially across water depths. Currently, most coral bleaching predictions are based on surface estimates of seawater temperatures, gathered with satellites over large areas of the ocean.
Plants get stressed too. Environmental factors such as drought or a high concentration of salt in the soil disrupt their physiology. All land plants, from liverwort to rye, use a complex signalling cascade under stressful conditions. An international research team led by the Hebrew University of Jerusalem with the participation of the University of Göttingen investigated how evolutionary changes in receptor proteins led to their ability to sense the plant hormone abscisic acid (ABA).
In 2018 the International Osteoporosis Foundation (IOF) and European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) published the updated European guidance for the diagnosis and management of osteoporosis in postmenopausal women.
An international group of scientists with IKBFU professor Anatoliy Snigirev among them has published an article that proposes a new method for studying the structure of complexly organized materials of both artificial and natural origin. The article was published by the Journal of Applied Crystallography.
Prof. Anatoliy Snigirev said:
Building materials that clean themselves could save immense time and labor in homes and businesses, as well as reduce disease risk in settings such as hospitals. Now, researchers reporting in ACS Applied Materials & Interfaces have made a new type of concrete that is strong, heat-insulating and soundproof -- and best of all, liquids like milk and coffee bounce right off of it, taking dust particles with them. Watch a video of the self-cleaning concrete here.
An article of the IKBFU Director of Institute of Physics, Mathematics and Informational Technology, Artyom Yurov and the Institute's Associate Professor, Valerian Yurov was recently published in European Physical Journal. The scientists have released their calculations, according to which the Universe may have quantum properties.
