Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats
Advanced Functional Materials, EarlyView.This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.

Generation of Orbital Angular Momentum Beam Using Fiber-to-Fiber Butt Coupling
IEEE Photonics Journal, 2018 We experimentally demonstrate a simple scheme for broadband generation of orbital angular momentum (OAM) using a fiber-based structure. A standard single-mode fiber (SMF) is stuck to a two-mode fiber (TMF) with specific offsets and tilt angles to realize

Vortices on demand in multicomponent Bose-Einstein condensates
, 2012 We present a simple mechanism to produce vortices at any desired spatial locations in harmonically trapped Bose-Einstein condensates (BEC) with multicomponent spin states coupled to external transverse and axial magnetic fields.

Vorticity and the birth of optical vortices
, 2019 We exploit the vorticity, familiar from fluid mechanics and the theory of superfluids, as a tool to track the birth and subsequent development of optical vortices at a spiral phase plate.

Advanced Functional Materials, EarlyView.Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

Vortex-lattice melting in a one-dimensional optical lattice
, 2006 We investigate quantum fluctuations of a vortex lattice in a one-dimensional optical lattice. Our method gives full access to all the modes of the vortex lattice and we discuss in particular the Bloch bands of the Tkachenko modes.

Advanced Functional Materials, EarlyView.A dual‐functional Li2B4O7 coating on carbon fibers is designed to resolve the critical interfacial degradation in sulfide all‐solid‐state batteries. The conformal layer acts as a physical barrier to suppress parasitic reactions while its unique dielectric properties simultaneously facilitate Li+ transport.
