Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

PENGARUH KECEPATAN PENGELASAN MIG TERHADAP KEKUATAN TARIK DAN PERUBAHAN STRUKTUR PATAHAN MAKRO PADA SAMBUNGAN ALUMINIUM

Otopro
MIG (Metal Inert Gas) welding is a welding process that uses rolled electrodes which are the same as the base metal and uses a protective gas.  Aluminum is one of the most commonly used metals in the industrial world.

Fluid/gravity correspondence: A nonconformal realization in compactified D4 branes

, 2016
We develop the framework of boundary derivative expansion (BDE) formalism of fluid/gravity correspondence in compactified D4-brane system, which is a nonconformal background used in top-down holographic QCD models. Such models contain the D4-D6 model and

A Computer Test of Holographic Flavour Dynamics [PDF]

, 2015
We perform computer simulations of the Berkooz-Douglas (BD) matrix model, holographically dual to the D0/D4-brane intersection. We generate the fundamental condensate versus bare mass curve of the theory both holographically and from simulations of the ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Corner contributions to holographic entanglement entropy in non-conformal backgrounds

, 2015
We study corner contributions to holographic entanglement entropy in non-conformal backgrounds: a kink for D2-branes as well as a cone and two different types of crease for D4-branes.

The longitudinal fivebrane and tachyon condensation in matrix theory [PDF]

, 1999
We study a configuration in matrix theory carying longitudinal fivebrane charge, i.e. a D0-D4 bound state. We calculate the one-loop effective potential between a D0-D4 bound state and a D0-anti-D4 bound state and compare our results to a supergravity ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

PERANCANGAN CYLINDER CATCHPOT VACUUM INFUSION SEBAGAI MEDIA PEMBUAT KOMPOSIT SERAT KARBON

Otopro
The use of metal or steel in a variety of applications has begun to be replaced by Carbon Fiber Reinforced Polymer (CFRP). Some of the advantages of CFRP include mechanical strength almost equal to, and sometimes exceeding, that of metal materials.
