Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Cell-Driven Fluid Dynamics: A Physical Model of Active Systemic Circulation

Active fluid circulation and transport are key functions of living organisms, which drive efficient delivery of oxygen and nutrients to various physiological compartments. Because fluid circulation occurs in a network, the systemic flux and pressure are not simple outcomes of any given component. Rather, they are emergent properties of network elements

Convective circulation in mesoscale abyssal basins

, 1998
Deep circulation in natural water basins that are smaller than the large global abyssal ocean, but bigger than a Rossby radius of deformation is both scantily documented and poorly understood. For buoyancy driving alone, angular momentum balance dictates

Dynamics of large-scale structures and heat transfer in turbulent mixed convection

, 2009
Low frequency oscillations have been observed in the heat transfer of mixed convection in a rectangular cavity with an aspect ratio of $\Gamma_{\mathrm{xz}} = 1$ and $\Gamma_{\mathrm{yz}} = 5$.~Mixed convective flow at $Ra = 2.4 \times 10^8$, $Re = 1.0 ...

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus

Advanced Materials Interfaces, EarlyView.
The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

Conservation properties of smoothed particle hydrodynamics applied to the shallow water equations [PDF]

, 2001
Conservation of potential vorticity (PV) and Kelvin's circulation theorem express two of the fundamental concepts in ideal fluid dynamics. In this note, we discuss these two concepts in the context of the Smoothed Particle Hydrodynamics (SPH) method. We
