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 Musculoskeletal 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

Nd1-xCaxFeO3 (x = 0, 0.3) Hollow Core-Shell Microspheres for Ethanol Gas Sensing

, 2015
The use of mesoporous and hollow structures is a promising strategy to enhance gas‐sensing properties. The framework of perovskite oxides has the ability to accommodate different cations, which endows it with rich oxygen deficiencies for preferable gas ...

Dual‐Component Spidroin‐Based Hydrogels: A Mechanically Tunable Platform for 2D and 3D Cell Culture

Small, EarlyView.
A dual‐component recombinant spider silk hydrogel platform was developed by combining NT2RepCT with a bioactive vitronectin‐functionalized spidroin domain. The hydrogels self‐assemble under physiological conditions, exhibit tunable mechanical properties, and support 2D and 3D cell culture, providing a versatile platform for mechanobiological studies ...

Preparation of Hollow Hydroxyapatite Microspheres

, 2006
The preparation of hollow hydroxyapatite (HA) microspheres as potential drug-delivery vehicles was investigated. A lithium-calcium-borate (10Li2O-15CaO-75B2O3) (mol%) glass, made by fusing the components at 1100°C for 1 h, was ground to a powder and ...
