The “Metaverse” (meaning “beyond universe”) is the next big subject in online world and it essentially a shared virtual space which life reality interact, co-exist, evolve together, various cultural, social, economic activities take place within them to create value. It combines an enhanced physical with encompass special technology; XR (eXtended Reality) includes VR (Virtual Reality), AR (Augm...

The elastic moduli of ultrathin poly(styrene) (PS) and poly(methylmethacrylate) (PMMA) films of thickness ranging from 200 nm to 5 nm were investigated using a buckling-based metrology. Below 40 nm, the apparent modulus of the PS and PMMA films decreases dramatically, with an order of magnitude decrease compared to bulk values for the thinnest films measured. We can account for the observed dec...

Nanotechnology has accelerated groundbreaking solutions at the molecular scale to help address many grand sustainability challenges. However, there are also growing concerns about known and unknown health environmental risks associated with production application of nanotechnology. This Voices asks: what where opportunities, must be taken into account, enable functional safe nanotechnology for ...

Suspended, high aspect ratio structures can be extremely flexible, to the point where they are overly delicate, difficult, and expensive to fabricate on wafers by standard undercut and release. However, capillary forces that normally destroy such structures can be redirected in ways to directly self-assemble nanoscale structures on top of fabricated wafers. One class of methods reviewed uses ca...

A chiral object is one that non-superimposable on its mirror image by rotational and translational operations. Chirality has unifying fundamental importance for physics, chemistry, astronomy, mathematics, biology, medicine.1, 2 It important to emphasize the discovery of chirality subsequent proliferation concepts asymmetry in these sciences were prompted chemical engineering research. compounds...
