Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

open access: yesAdvanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Gyroid Structured Globugraphite Carbon Foam With Hierarchical and Tailored Pore Size

open access: yesAdvanced 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.

Lightweight Cryptography for FPGAs

open access: yes2009 International Conference on Reconfigurable Computing and FPGAs, 2009
The advent of new low-power Field Programmable Gate Arrays (FPGA) for battery powered devices opens a host of new applications to FPGAs. In order to provide security on resource constrained devices lightweight cryptographic algorithms have been developed. However, there has not been much research on porting these algorithms to FPGAs.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Steel Straps Confined Lightweight Foamed Concrete

open access: yes, 2021
Lightweight foamed concrete is originally unable to be used for main structural members such as column, beam and slab due to its low in compressive strength and ductility.

Lightweight hybrid tableaux

open access: yesJournal of Applied Logic, 2010
The paper presents a decision procedure for some fragments of the hybrid logic. The main difference between hybrid logic and modal logic is the presence of nominals, which are propositional symbols true at exactly one world in a model. The decision procedure is based on a prefixed tableau calculus.
