Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Recent Advances in Cryogel Applications for Musculoskeleatal Regeneration

Medicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Template-free microsphere and hollow sphereformation of polymethylanilines

, 2009
BACKGROUND: Microsphere and/or hollow sphere formation of methyl-substituted polyaniline derivatives was investigated via chemical polymerization where different sets of conditions were examined. It was found that a variety of parameters (e.g. types and concentrations of monomer and oxidant, polymerization time, solvent with and without acid) have a ...
