Researchers in Spain have devised a new parameter for comparing and understanding bonds which can replace previous distance measurements with simple calculations. It describes the degree of interpenetration of the van der Waals crusts of two atoms.

#VanderWaals integration permits novel hetero-integrated #photonicdevices and flexible optical applications @nature https://www.nature.com/articles/s41578-023-00558-w https://phys.org/news/2023-04-van-der-waals-hetero-integrated-photonic.html
Today, electronic and photonic devices are ubiquitous in smart phones, computers, light sources, sensors, and communications. To underpin the demand for optoelectronic applications, functional materials are essential. For instance, silicon is required for logic computing and photonic integrated circuits (PIC); group III-V semiconductors (such as GaAs, InP, AlN, etc.) are used for optoelectronic, light-emitting and photodetection applications; and piezoelectric materials are used for actuators and sensors.

Low-pass #filters based on thin films of #vanderWaals ferromagnets @NatureElectron https://www.nature.com/articles/s41928-023-00941-z https://phys.org/news/2023-04-low-pass-filters-based-thin-van.html
Two-dimensional (2D) magnets, also known as magnetic van der Waals materials, have advantageous electrical and mechanical properties, such as antiferromagnetic or ferromagnetism. These properties make them particularly promising for the development of new technologies and systems, including spintronic devices and 2D nanoelectromechanical systems (NEMS).

Beautiful video, thank you.
Interesting that it raises as many feet as it can before taking off… I’d surmise (but it’s my guess only) that it does that on purpose to reduce the van der Waals grip of its feet on the leaf, to make takeoff as easy as possible. Given the fairly sluggish departure, I’m guessing that without reducing that grip, it mightn’t be able to lift off at all—but that’s just a guess.

A UNSW paper published recently in Nature Reviews Materials presents an exciting overview of the emerging field of 2D ferroelectric materials with layered van der Waals crystal structures, a novel class of low-dimensional materials that is highly interesting for future nanoelectronics.
