The present invention relates to a method of reducing carbon dioxide and air pollutants, and more particularly to a method of simultaneously reducing emissions of carbon dioxide and air pollutants, in which an off-gas containing carbon dioxide, SOx, and NOx is passed through a sulfur-oxidizing microorganism reactor, thereby converting carbon dioxide present in the off-gas into biomass, SOx into sulfate ions, and NOx into amino-N.

Method of reducing carbon dioxide and air pollutants

Provided are a layer-separation method of a spent caustic solution, and a recycling method of an additive, and more particularly, a layer-separation method of a spent caustic solution including: injecting an additive and an acidic compound to the spent caustic solution occurring from a refinery process to break down a red oil emulsion and to perform layer-separation into an upper layer fraction and a lower layer fraction, wherein the additive is an aliphatic hydrocarbon compound having a water solubility of 0.1 to 10 g/L at 20&#xb0; C.

Layer-separation method of spent caustic solution

Disclosed are a carbonic anhydrase mutant having heat resistance at a high temperature of 80&#xb0; C. as well as excellent activity to capture carbon dioxide and a composition for capturing carbon dioxide containing the same. The heat-resistant carbonic anhydrase mutant can be applied to a high-temperature carbon dioxide capture process due to high stability at high temperatures and a high carbon dioxide hydration rate.

A PNA zip-code chip in which PNA zip-code probes are immobilized on a substrate at high density using an epoxy compound as a linker, and method for fabricating such PNA chip. The use of PNA provides the chip with superior properties to DNA chips, allowing precise diagnosis of congenital diseases or base mutations with much higher sensitivity than is achievable with a DNA chip. The use of the PNA zip-code chip enables diagnosis of gene mutations in a simple manner, using only hybridization reaction, without the difficulties associated with processes in which probes must be immobilized directly on a substrate every time the target gene changes.
