First, the model of electrostatic force is demonstrated. As depicted in Fig. 1, dominated by the photoelectron effect induced by solar ultraviolet and x-ray radiation, the spacecraft and lunar ...
Due to the unique conditions of the space environment and abundant resources, the field investigation and study of the Moon, ...
What if the very principles that have powered industry for over a century were suddenly turned on their head? For decades, electromagnetic motors—reliant on copper windings and rare earth magnets—have ...
Quad has updated its long-running ESL series of electrostatic loudspeakers with two new models: the ESL 2812X and its smaller ESL 2912X sibling. We've glimpsed a preview of this new generation of ESL ...
The IAEA has released a new publication on electrostatic accelerator operation and management and launched a series of training workshops on accelerator technologies. From analysing cultural heritage ...
Car hi-fi speakers are heavy, bulky and wasteful of power. Packaging the speakers in the doors or dash is a headache. So is getting rid of the heat they generate. Now imagine a speaker that isn’t a ...
AMSTERDAM, Nov 12 (Reuters) - Oil and gas major Shell (SHEL.L), opens new tab on Tuesday won an appeal against a landmark ruling that required it to accelerate carbon reduction efforts, dealing a blow ...
A Dutch appeals court on Tuesday ruled in favor of oil giant Shell and overturned a landmark 2021 ruling by a lower court that ordered the company to sharply reduce its carbon emissions by the end of ...
The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
The original version of this story appeared in Quanta Magazine. Imagine, for a moment, that you’re a honeybee. In many ways, your world is small. Your four delicate wings, each less than a centimeter ...
Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen and more. New experiments explore how evolution may have influenced this phenomenon.
Abstract: This article describes a method for stiffness tuning (ST) of a hemispherical shell resonator (HSR) based on the electrostatic forces applied to discrete electrodes. The frequency splitting ...
