Massive production of graphene oxide from expanded graphite [PDF]

, 2013
In a deviation from the conventional Hummers method, a spontaneous expansion approach was introduced with expanded graphite as the precursors. The intercalating agent (H2SO4) was able to penetrate into the expanded graphite; this had further expanded the

A Gauge-Independent Mechanism for Confinement and Mass Gap: Part I -- The General Framework

, 2009
We propose a gauge-independent mechanism for the area-law behavior of Wilson loop expectation values in terms of worldsheets spanning Wilson loops interacting with the spin foams that contribute to the vacuum partition function.

Preparation of Papaya Powder under Foam-Mat Drying Technique using Egg Albumin as Foaming Agent

International Journal of Bio-Resource and Stress Management, 2023
Foam-mat drying of papaya pulp using egg albumin as foaming agent was investigated. The egg albumin was incorporated into papaya pulp at 5, 10, 15 and 20% (w/w) and whipped for 5, 10, 15 and 20 min in room temperature.

Multiphysics Modeling of a Metal Foam [PDF]

, 2014
In metal foam processing nucleated gas bubbles expand in a heated metal, then the foam cools and solidifies. In this work we use Comsol Multiphysics 4.2 to study heat transfer, growth and movement of hydrogen gas bubbles in liquid aluminium for a ...

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]

, 2016
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.
