Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world''s use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.
Mining, processing and transporting sand generate large quantities of silica dust, which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called "fracking," has led to boom in sand mining across the upper Midwest, creating a ...
Silica resins avoid these issues through integration on microchips, where solid phase extraction provides accurate analysis of DNA on a small scale. Operations. In order to conduct DNA separation by silica adsorption, a sample (this may be anything from purified cells to a tissue specimen) is placed onto a specialized chip and lysed.
