An atmospheric plasma spray device is used to direct a stream of plasma-heated, particulate, lithium battery electrode materials to form a porous layer of the electrode particles on a surface of a compatible current collector metal foil. Subsequently, a non-plasma spray device is used to direct a stream of droplets of an aqueous solution of a polymeric binder material onto and into the porous layer of electrode particles. Water evaporates from the droplets of binder solution as the droplets infiltrate the porous electrode material and coat the electrode particles and current collector surface. When the water (or other solvent) has evaporated from the dispersed droplets of polymer material, the polymer binder bonds the particles to each other and to the current collector surface. The polymer spray may immediately follow the deposition of the electrode particles, or follow later, even at a downstream spray location.

Three-dimensional fluorescence lifetime microscopy is achieved by combining wide-field fluorescence lifetime imaging with a remote optical refocusing method. As required for some applications in dynamic research for physics, chemistry, or biology, it is thereby not necessary to move the sample, i.e., the specimen is not disturbed during measurement. Using a fluorescent microsphere the performance of the system has been tested successfully with respect to three-dimensional fluorescence lifetime microscopy as well as time-resolved fluorescence spectroscopy.
Multilinear algebra of the higher-order tensor has been proposed as a potential mathematical framework for machine learning to investigate the relationships among multiple factors underlying the observations. One popular model Nonnegative Tucker Decomposition (NTD) allows us to explore the interactions of different factors with nonnegative constraints. In order to reduce degeneracy problem of tensor decomposition caused by component delays, convolutive tensor decomposition model is an appropriate model for exploring temporal correlations. In this paper, a flexible two stage algorithm for K-mode Convolutive Nonnegative Tucker Decomposition ( K-CNTD) model is proposed using an alternating least square procedure. This model can be seen as a convolutive extension of Nonnegative Tucker Decomposition. The patterns across columns in convolutive tensor model are investigated to represent audio and image considering multiple factors. We employ the K-CNTD algorithm to extract the shift-invariant sparse features in different subspaces for robust speaker recognition and Alzheimer's Disease(AD) diagnosis task. The experimental results confirm the validity of our proposed algorithm and indicate that it is able to improve the speaker recognition performance especially in noisy conditions and has potential application on AD diagnosis.
