Topological birefraction of elastic waves in phononic crystals [PDF]
AIP AdvancesThe refraction of waves at the interface between two different media is one of the most common phenomena in nature, which is always accompanied by reflection.

Opto-optical light deflection [PDF]
Applied Optics, 1983 Light deflection is accomplished by diffraction from a transient index modulation established as a grating of variable frequency in an optical material by the interference of two controlling light beams. This device may be considered an opto-optical analog to an acoustooptical deflector, in that a change in angular deflection is created by altering the

Nanostructures + Light = ‘New Optics’ [PDF]
Journal of Optics A: Pure and Applied Optics, 2005 Suddenly, at the end of the last century, classical optics and classical electrodynamics became fashionable again. Fields that several generations of researchers thought were comprehensively covered by the famous Born and Wolf textbook and were essentially dead as research subjects were generating new excitement.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
