Nanoporous Inorganic Solids

- Nanoporous Inorganic Solids A porous inorganic material is one which does not have pores and voids through and through. The voids show a translational repetition in 3-D space, while no regularity is necessary for a material to be termed “porous.” A typical and relatively simple porous system is one type of dispersion classically described in colloid science, namely foam or, better, solid foam (M. Jaroniec, 2002). In correlation with this, the most common way to think about a porous material is as a material with gas-solid interfaces as the most dominant characteristic....   [tags: pores, voids, porous materials, gas]

Solids, Liquids, and Gases

- Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between it's atoms. The tighter the bond between it's atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape and do take the shape of their container, the same is true with gases....   [tags: essays research papers]

History of Colloidal Mills

- ... The material to be ground should be pre milled as finely as possible to prevent damage to the colloidal mill. Rotors and the stator may be smooth surfaced or rough surface. With the rotor and the stator there is a thin uniform film of material between them and it is subjected to the maximum amount of shear. Rough surfaced mill add intense eddy current, turbulence and the impaction of the particles to the shearing action. Principle Colloidal mill works on the principle of rotor-stator. The size reduction is affected due to shearing, when the material is passed between the narrow gap of milling surfaces of rotor and stator....   [tags: reducing solids, mixing technology]

- Hygroscopicity in Pharmaceutics During formulation of new and existent drugs in pharmaceutics, hygroscopicity is one of the important physical parameters that are studied so as to enhance the efficacy, stability and handling of the drug. Hygroscopicity has always been an important aspect in pharmaceutics as the bulk of the drugs either in tablet or solution form is normally hygroscopic. Up to now, there remains no universally recognized definition of hygroscopicity because it is driven by both thermodynamic and kinetic forces....   [tags: Pharmaceuticals]

Preparation A Acid Base Extraction Technique For Separate Organic Compounds Successfully By Separatory Funnel Preforming On Two Liquids

- The Objective The purpose of this experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture. In this experiment, the separation will be done by separatory funnel preforming on two liquids that are immiscible from two layers when added together. The individual components of Phensuprin (Acetylsalicylic acid, Acetanilide, and Sucrose as a filler) was separated based upon their solubility and reactivity, and the amount of each component in the mixture was obtained....   [tags: Solvent, Sodium bicarbonate, Hydrochloric acid]

Louisiana has lost up to forty square miles of marsh per year for several decades (accounting for 80% of the nation’s annual coastal wetland loss) (lacoast.gov). From a hydrologic standpoint, the wetlands replenish aquifers, hold excess floodwaters from intense rainfalls, and provide storm surge protection. The Nation also benefits from Louisiana’s coastal lands. Louisiana is responsible for a major part of our nation’s oil and gas production, shipping commerce, fisheries industry, fur harvesting, and oyster production, accounting for over 55,000 jobs and billi...   [tags: louisiana, soils, ]
