New 'bi-molecule' with multiple technological applications discovered

University of Granada scientist discovers a new type of 'bi- molecule' that could help develop quantum sensors with multiple technological applications

New 'bi-molecule' with multiple technological applications discovered
2021-03-25
(Press-News.org) Dr. Rosario González-Férez, a researcher at the Department of Atomic, Molecular and Nuclear Physics and the "Carlos I" Institute of Theoretical and Computational Physics of the University of Granada, has published the article "Ultralong-Range Rydberg Bi-molecules" in the prestigious scientific journal Physical Review Letters. The results of the study show a new type of bi-molecule formed from two nitric oxide (NO) molecules, both in their ground state and in the Rydberg electronic state. The work was made possible thanks to the scientific collaboration between the researcher and the Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP) at Harvard University. The study began during her stay at Harvard between March and July 2020, meaning that the entire process, from data-gathering and analysis to final written conclusions, was conducted during the Covid-19 pandemic. The stay, which was funded by the Fulbright Foundation and the Salvador de Madariaga programme of the Spanish Ministry of Science, Innovation and Universities, enjoyed the scientific collaboration of ITAMP's Hossein R. Sadeghpour and Janine Shertzer. This new type of bi-molecule is the result of the union of two molecules of nitric oxide (NO) whose structure is arranged in such a way that the NO is located in one of the poles, while, in the other, is the NO + ion. The electron orbits around both, acting like a "glue" that binds this bi-molecule. In addition, its size corresponds to between 200 and 1,000 times that of NO, and its lifetime is long enough to enable its observation and experimental control, as these fragile systems are easily manipulated by means of very weak electric fields. This type of bi-molecule enables researchers to implement and study chemical reactions at low temperatures from a quantum perspective and facilitates the investigation of intermolecular interactions at large distances, since they coexist at low temperatures. Dr. González-Férez observes that the use of these bi-molecules in quantum technologies would be interesting both for the processing of information by entanglement and for the development of quantum sensors, with multiple technological applications in quantum optics and quantum computing. González-Férez continues her work with two research groups, from the University of British Columbia in Canada and the University of Stuttgart in Germany, which aims to create this bi-molecule experimentally and confirm the theoretical predictions made over the last year.

SMART develops rapid deterministic lateral displacement assay to assess immune response
2021-03-25
The novel label-free assay uses unconventional L and inverse-L shaped pillars of deterministic lateral displacement (DLD) microfluidic technology to quantify and profile immune states of white blood cells (WBCs) by assessing biophysical properties of size, deformation, distribution, and cell count The assay requires only 20 microlitres (μl) of unprocessed blood and takes just 15 minutes - much faster than existing methods which require up to 15 millilitres (ml) of blood and take at least a few hours to produce results This new technology measures and profiles the often volatile host immune response, resulting in a more accurate assessment of patient pathophysiology Current methods for early diagnosis of infection focus on ...

The imaginary part of quantum mechanics really exists!

The imaginary part of quantum mechanics really exists!
2021-03-25
For almost a century, physicists have been intrigued by the fundamental question: why are complex numbers so important in quantum mechanics, that is, numbers containing a component with the imaginary number i? Usually, it was assumed that they are only a mathematical trick to facilitate the description of phenomena, and only results expressed in real numbers have a physical meaning. However, a Polish-Chinese-Canadian team of researchers has proved that the imaginary part of quantum mechanics can be observed in action in the real world. We need to significantly reconstruct our naive ...

New study sheds light on how X and Y chromosomes interact

2021-03-25
Researchers at Lund University in Sweden have investigated how the X and Y chromosomes evolve and adapt to each other within a population. The results show that breaking up coevolved sets of sex chromosomes could lead to lower survival rates among the offspring - something that could be of importance in species conservation, for example. The study is published in the journal PNAS. The results provide new clues on how species are formed, and suggest it could be harmful to bring together individuals from different populations that have been separated for a long time. The reason is that the offspring have lower survival rates. "This is something worth keeping in mind in conservation biology, where you want to see a population ...

Ancient megafaunal mutualisms and extinctions as factors in plant domestication

Ancient megafaunal mutualisms and extinctions as factors in plant domestication
2021-03-25
By clearing forests, burning grasslands, plowing fields and harvesting crops, humans apply strong selective pressures on the plants that survive on the landscapes we use. Plants that evolved traits for long-distance seed-dispersal, including rapid annual growth, a lack of toxins and large seed generations, were more likely to survive on these dynamic anthropogenic landscapes. In the current article, researchers argue that these traits may have evolved as adaptations for megafaunal mutualisms, later allowing those plants to prosper among increasingly sedentary human populations. The new study hypothesizes that the presence of specific anthropophilic traits explains why a select few plant families came to dominate the crop and weed ...

New documentation: Old-growth forest carbon sinks overestimated

2021-03-25
The claim that old-growth forests play a significant role in climate mitigation, based upon the argument that even the oldest forests keep sucking CO2 out of the atmosphere, is being refuted by researchers at the University of Copenhagen. The researchers document that this argument is based upon incorrectly analysed data and that the climate mitigation effect of old and unmanaged forests has been greatly overestimated. Nevertheless, they reassert the importance of old-growth forest for biodiversity. Old and unmanaged forest has become the subject of much debate in ...

A divided cell is a doubled cell

2021-03-25
One big challenge for the production of synthetic cells is that they must be able to divide to have offspring. In the journal Angewandte Chemie, a team from Heidelberg has now introduced a reproducible division mechanism for synthetic vesicles. It is based on osmosis and can be controlled by an enzymatic reaction or light. Organisms cannot simply emerge from inanimate material ("abiogenesis"), cells always come from pre-existing cells. The prospect of synthetic cells newly built from the ground up is shifting this paradigm. However, one obstacle on this path is the question of controlled division--a requirement for having "progeny". A team from the Max Planck Institute for Medical Research in Heidelberg, Heidelberg ...

Researchers dig deeper into how migrating cells interact in the body

2021-03-25
By offering a microscopic "tightrope" to cells, Virginia Tech and Johns Hopkins University researchers have brought new insights to the way migrating cells interact in the body. The researchers changed their testing environment for observing cell-cell interaction to more closely mirror the body, resulting in new observations of cells interacting like cars on a highway -- pairing up, speeding up, and passing one another. Understanding the ways migrating cells react to one another is essential to predicting how cells change and evolve and how they react in applications, such as wound healing and drug delivery. In a study published in the Proceedings of the National Academy of Sciences, a team formed by Mechanical Engineering Associate ...

TPU scientists develop sensor with nanopores for definition doping in blood
2021-03-25
Scientists of Tomsk Polytechnic University jointly with colleagues from different countries have developed a new sensor with two layers of nanopores. In the conducted experiments, this sensor showed its efficiency as a sensor for one of the doping substances from chiral molecules. The research findings are published in Biosensors and Bioelectronics (IF: 10,257; Q1) academic journal. The material is a thick wafer with pores of 20-30 nm in diameter. The scientists grew a layer of metal-organic frameworks (MOF) from Zn ions and organic molecules on these thick wafers. The MOF has about 3 nm nanopores only. It plays the role of a trap for molecules, which must be detected. "This sensor can operate with chiral molecules. Such substances consisting of chiral molecules are a lot among medical ...
