The enhancement and suppression of -- &#; Abstract Heterogeneous nucleation of ice from aqueous solutions is an important yet poorly understood process in multiple fields, not least the atmospheric sciences where it impacts the formation and properties of clouds.

Enhanced flame retardancy and smoke suppression of-- &#; The flame retardant and smoke suppression performances of the nanocomposites were characterized by microscale combustion calorimeter (MCC) and smoke density tester, respectively. The results showed that the prepared ZnO nanowires/PP nanocomposites possessed good thermal stability, flame retardant and smoke suppression performances.

Heterogeneous Two-Atom Single-Cluster Catalysts for the The key to achieve it is to find stable, efficient and selective catalysts. Recently, the heterogeneous single-cluster catalysts (SCCs) have emerged as a promising class of catalysts for electrochemical reactions due to their atomically precise active site, abundant active atoms and atomic level controllability.

Robust clutter suppression in heterogeneous -- &#; Experimental results based on measured data demonstrate that the proposed method improves the performance of clutter suppression in heterogeneous environments effectively. Signal model for STAP Denote the observed vector of the CUT as { {\bf x}}_ {k,l}, where k and l are the frame index and range gate index of the CUT, respectively.

Heterogeneous sensing in a multifunctional soft sensor for First, we describe the design of the sensing structure composed of three sensing elements—such as the soft optical waveguide, the ionic liquid channel, and the conductive fabric layer—densely packaged in an elastomer body. Second, we discuss the working mechanisms of the three sensing elements on physical deformations with simulation results.
