A spike protein is a tool that helps a virus to enter the cell.
If you look at an illustration of SARS-CoV-2, you will notice all the protruding structures on its extremities. The main job of these spike proteins is to join to receptors – called ACE2 receptors – on the surface of a cell and force the viral genome inside.
Las políticas de retribución al accionista de las cotizadas del Ibex vuelven poco a poco a la situación precovid. De hecho, de las 35 compañías que forman el Ibex, 25 tienen previsto mejorar la retribución al accionista de cara a 2022. Según las previsiones que maneja el consenso de FactSect, de éstas, diez de ellas tienen pensado incrementar estas cifras por encima del 20%.
La escasez de microchips ha provocado que este año ya sea peor que el anterior en volumen de vehículos fabricados en España. Según datos ofrecidos por la Asociación Nacional de Fabricantes de Automóviles (Anfac), la producción de coches ha caído en el mes de octubre en comparación con el mismo mes del ejercicio pasado un 37,9%. Así, en lo que va de 2021, las plantas nacionales han fabricado un total de 1.757.000 unidades, lo que supone un recorte del 2,5%.
El Consejo de Ministros ha aprobado este martes el anteproyecto de ley de planes colectivos de pensiones de empleo, que bajo batuta pública y con unas comisiones limitadas los promoverá como alternativa a los planes individuales, los más extendidos hoy entre la población.
With the increase in battery-powered electric vehicles (BEVs, HEVs and PHEVs) on the road, statistically the risk potential for an accident or technical defect of the inherently safe battery systems also increases. However, for the most part, emergency crews do not have appropriate equipment and/or techniques to counter these fires, the response to which entails many unknown factors.
Yara Birkeland —the world’s first battery- electric container ship, prepared for autonomous operation—has departed for its maiden voyage in the Oslo fjord. The autonomous ship will sail within 12 nautical miles from the coast, between 3 ports in southern Norway.
We are proud to be able to showcase the world’s first fully electric and self-propelled container ship. It will cut 1,000 tonnes of CO2 and replace 40,000 trips by diesel-powered trucks a year.
Energy storage technology company Tesvolt has concluded a funding round, raising around €40 million (US$45.25 million) in equity capital.
Germany-headquartered Tesvolt assembles energy storage systems (ESS) for a variety of commercial and industrial (C&I) markets, using third party-supplied prismatic nickel manganese cobalt (NMC) lithium-ion battery cells.
It has received orders worth close to €100 million for this year so far, the company claimed, and it opened a factory in Wittenberg, Germany, with 255MWh annual production capacity in April 2020.
A new study confirms that as atoms are chilled and squeezed to extremes, their ability to scatter light is suppressed.
An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli exclusion principle, and it explains the shell structure of atoms, the diversity of the periodic table of elements, and the stability of the material universe.
Global solar photovoltaic (PV) installations will see over 20% growth in 2022 and surpass the 200GW (DC) barrier for the first time, at a total investment of at least $170bn, according to a new report.
IHS Markit’s study predicts solar PV installations to experience double-digit growth in 2021.
Continued growth through 2022 would mark the second year in a row to experience double-digit growth of global installations in a high-price environment, the report highlighted.
