Processing and Properties of Graded Ceramic Filters [PDF]
Journal of the American Ceramic Society, 2009 A new processing route for high‐performance graded ceramic filters is presented. The direct foaming process is based on the transition of a surfactant‐stabilized alkane dispersion in a stabilized aqueous ceramic powder suspension into mechanically stable ceramic foams with porosities up to 90%.

Electrodeposition in Structural Lattices of Variable Architectures
Advanced Engineering Materials, EarlyView.Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Methodology for reducing the filtering capacitor in low-flicker LED drivers
The Journal of Engineering, 2017 The amount of light flicker in an AC–DC light-emitting diode (LED) driver is dependent on the size of filter capacitors. In this study, a study is conducted on reducing the size of filter capacitor in an AC–DC buck–boost/flyback LED driver using flicker ...

Monolithic integrated ceramic waveguide filters [PDF]
2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014 Design techniques for a new class of integrated monolithic high permittivity ceramic waveguide filters are presented. These filters enable a size reduction of 50% compared to air-filled TEM filters with the same unloaded Q-Factor. Designs for both chebyshev and asymmetric generalized chebyshev filter are presented, with experimental results for an 1800

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel
Advanced Engineering Materials, EarlyView.Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

Gyroid Structured Globugraphite Carbon Foam With Hierarchical and Tailored Pore Size
Advanced Engineering Materials, EarlyView.Secondary sacrificial templates were designed and printed to create a defined network within a porous carbon. Lattices thermally degrades during the sintering process. Lattices are imprinted into the ceramic template and transferred to the morphology of Globugraphite.
