If a sol of colloidal ferric hydroxide is added to sea water, or if the hydroxide is formed in sea water by adding a solution of an iron salt, the aggregated molecules of hydroxide coalesce to form flocs which fall rather rapidly as a precipitate. When several thousand mg. of iron are added per cubic metre of sea water, flocculation is immediate; on adding 300-500 mg. Fe per m.3 in sufficiently...

Thermally reduced graphite oxide (TRGO), containing only four single carbon layers on average, was combined with ammonium polyphosphate (APP) and magnesium hydroxide (MH), respectively, in polypropylene (PP). The nanoparticle’s influence on different flame-retarding systems and possible synergisms in pyrolysis, reaction to small flame, fire behavior and mechanical properties were determined. TR...

Alkali-activated slag is commonly used as a cement substitute to reduce the environmental footprint of construction materials. Nonetheless, use significant amount alkaline activators, such sodium silicate or hydroxide, can be detrimental in terms global warming potential impact. The aim this work complementary activators partial replacement and therefore activated binder. Calcium calcium carbon...

Studies were carried out by the grapevine berries sprayed with copper hydroxide (Kocide 3000) to assess its quality in terms of reducing sugars, non reducing sugars, total sugars and acidity. The total, reducing and non reducing sugars were higher in the grapevine berries sprayed with Copper hydroxide comparing with that of control plots. Fruit quality was improved in Copper hydroxide (Kocide 3...

This paper reports the development of optical lever based parylene cantilevers for biochemical sensing. A simple but effective process to fabricate parylene cantilevers using Tetramethylammonium Hydroxide (TMAH) bulkmicromachining was demonstrated. A scheme of using anchoring holes was employed to prevent the peeling off of parylene during TMAH etching. Moreover, ridge structures were incorpora...

Magnesium hydride is cheap and contains 7.7 wt % hydrogen, making it one of the most attractive hydrogen storage materials. However, thermodynamics dictate that hydrogen desorption from bulk magnesium hydride only takes place at or above 300 degrees C, which is a major impediment for practical application. A few results in the literature, related to disordered materials and very thin layers, in...
