Compact, fiber-compatible, cascaded Raman laser [PDF]

open access: yesOptics Letters, 2003
Cascaded Raman Stokes lasing in an ultrahigh-Q silica microsphere resonator coupled to a tapered fiber is demonstrated and analyzed. With less than 900 microW of pump power near 980 nm, five cascaded Stokes lasing lines are generated. In addition, a threshold power of 56.4 microW for the first-order Stokes lasing is achieved.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

open access: yesAdvanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Multifunctional Thiolated Hyaluronic Acid‐graft‐PEDOT Dressing With Antifouling, On‐Demand Drug Delivery and Electrical Stimulation for Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
A multifunctional P(EDOT‐co‐EDOT‐g‐THA) dressing acts as a dynamic biointerface integrating antifouling capability, on‐demand drug delivery, and electrical stimulation. It achieves electrochemically triggered thiolated hyaluronic acid (THA) release while modulating cellular responses for wound healing application.
