A nanotechnology-based electrochemical DNA sensing apparatus and method [abstract]

DNA is a code that contains the building instructions for all organisms and is the ultimate identification card. For example, the DNA code of a particular bacterium can tell if that particular strain of the bacterium is harmful or not. DNA sensing and recognition devices are therefore essential for accurate detection of bacteria and other microbes, as well as for detection and identification of viruses, and there is a critical need to develop better methods and devices for DNA detection. The current invention developed by researchers at the University of Missouri is a new technology that will increase the DNA sensor sensitivity, specificity, and sensing speed over current methods. This novel invention consists of an electrolyte cell, an electrochemical measurement device, and a nanostructured ceramic base electrode. The device is so sensitive that it does not require amplification of the DNA by PCR and it is advantageous due to its reusability, its increased detection speed, and its specificity. Potential Areas of Applications: * Recognition of bacteria, viruses and protozoans of medical and public health importance * Environmental analysis such as water quality monitoring * Biological attack and prevention * Food safety * Genetic research and application * Pathology and criminolog

Investigation of thermal breakage and heat transfer in single, insulated and laminated glazing under fire conditions

To make constructions more artistic, various new kinds of glazing are increasingly employed in building envelopes. However, when subjected to a fire, these glass façades may easily break and fall out, significantly accelerating the development of enclosure fire. Thus, it is necessary to investigate and compare their different fire performance and breakage mechanisms. In this work, a total of ten tests, including single coated, insulated and laminated glazing, were heated by a 500 × 500 mm2 pool fire. Breakage time, glass surface and air temperature, incident heat flux and crack initiation and propagation were obtained. The critical conditions of three different kinds of glazing were determined. It was established that the insulated and laminated glass can survive longer than the single glass. The air gap and fire side glass pane was found to play a key role for the thermal resistance of ambient side pane in the insulated glazing. Although both panes of the laminated glazing broke, it could be held together by the layer of gel, effectively avoiding the formation of a new vent. Numerical simulations were performed to investigate the heat transfer process through the glazing panels and the temperatures in the glazing were predicted well. Suggestions for glass fire resistance design are proposed
