Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets
Advanced Engineering Materials, EarlyView.Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

Advanced Engineering Materials, EarlyView.A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.

A microfluidic bubble trap and oscillator.
Lab on a Chip, 2015 A new approach to trap air bubbles before they enter microfluidic systems is presented. The bubble trap is based on the combined interaction of surface tension and hydrodynamic forces.

Shear-free boundary in Stokes flow
International Journal of Mathematics and Mathematical Sciences, 1996 A theorem of Harper for axially symmetric flow past a sphere which is a stream surface, and is also shear-free, is extended to flow past a doubly-body 𝔅 consisting of two unequal, orthogonally intersecting spheres. Several illustrative examples are given.

Journal of High Energy Physics, 2019 AbstractWe build the first family of smooth bubbling microstate geometries that are asymptotic to the near-horizon region of extremal five-dimensional Kerr black holes (NHEK). These black holes arise as extremal non-supersymmetric highly-rotating D1-D5- P solutions in type IIB string theory on T4×S1.

Advanced Functional Materials, EarlyView.Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for
