Korean to English: Formic Acid from Carbon Dioxide (News of HelloDD, a Korean Journal) General field: Science Detailed field: Chemistry; Chem Sci/Eng
Source text - Korean 이산화탄소로 포름산을 제조하는 기술은 전혀 새로운 것은 아니지만 우리가 사용할 수 있을 정도의 정제된 포름산을 분리하는 과정에 어려움이 많았다. 기존 기술의 한계성을 극복하기 위해 윤 교수는 촉매기술을 변형시켰다. 또 균질계 촉매로 포름산을 만들었던 예전 방식에서 벗어나 비균질계 촉매화를 시켰다. 이를 통해 높은 압력과 온도에서 버티면서도 쉽게 침전이 일어나게 하는 등 액상분리를 통해 포름산 유도체을 얻어내는데 성공했다.
물론 난제도 있었다. 포름산 정제를 위해 필요한 촉매로 이리듐을 사용했는데 고가의 귀금속계로 경제성이 좋지 않았다. 그는 "촉매는 재활용도 중요한데 이리듐을 재활용하니 효율이 떨어지는 단점이 있었다. 값싼 촉매로 경제성 높은 생산에 고민이 많았다"고 설명했다.
윤 교수팀은 이리듐을 대체할 촉매 '루테늄'개발에 성공했다. 이리듐보다 3배 이상 저렴한 가격에 재활용해도 효율이 유지되는 것을 연구를 통해 확인했다.
Translation - English Producing formic acid from carbon dioxide is not a totally new technology. But there has been much trouble to separate the refined formic acid, which is enough to use.
To overcome the limit of conventional technology, Professor Yoon modified the catalyst technology. He introduced the non-homogeneous catalysis, not following the conventional method of using homogeneous catalyst for producing formic acid. This change made the formic acid solution possible to withstand high pressure and temperature, and to be easily precipitated. So it was possible to get formic acid derivative by liquid phase separation.
Also there was a problem. He used Iridium catalyst to refine formic acid. But Iridium is a kind of precious metal, so the price is high and it has low economic feasibility. He said, “For catalyst, reusing is very important. But I found that the efficiency was decreased when reusing Iridium. I had hard time to come up with the way to produce with high feasibility using cheap catalysts”.
Prof. Yoon’s research team has succeeded in developing ‘Ruthenium’ catalyst to replace Iridium. They verified that Ruthenium kept its original efficiency after reusing, even its price is less than one third of Iridium.
English to Korean: Navier-Stokes equations General field: Science Detailed field: Mechanics / Mech Engineering
Source text - English In physics, the Navier–Stokes equations /nævˈjeɪ stoʊks/, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of viscous fluid substances. These balance equations arise from applying Newton's second law to fluid motion, together with the assumption that the stress in the fluid is the sum of a diffusing viscous term (proportional to the gradient of velocity) and a pressure term—hence describing viscous flow. The main difference between them and the simpler Euler equations for inviscid flow is that Navier–Stokes equations also factor in the Froude limit (no external field) and are not conservation equations, but rather a dissipative system, in the sense that they cannot be put into the quasilinear homogeneous form:
Translation - Korean Navier-Stokes 방정식, Claude-Louis Navier와 George Gabriel Stokes의 이름을 딴 이 식은 점성유체의 거동을 묘사하는 물리 방정식이다. 이 식은 Newton 제 2법칙을 유체의 움직임에 적용하여 만들어졌으며, 유체 내의 응력(Stress)은 점성 확산 항 (속도 경사(구배)에 비례)과 압력 항의 합으로 가정하였다 (이를 통해 점성 흐름을 묘사). 비점성유체에 있어 이 식과 좀 더 단순한 형태인 Euler 방정식의 주요 차이점은 Navier-Stokes 방정식은 Froude 수를 무한대까지 (외부장은 무시할 정도로 작은) 고려했으며, 물리량이 보존되기보다는 사라지는 시스템이라는 점이다. 이런 의미에서 이 식은 준(quasi)선형이나 homogeneous 형태로 나타낼 수 없다.

I have been working as a chemical business developer for 4.5 years in Korea.
My field of expertise includes investigating the chemical background of new business.
Carrying out new business related works, I used to translate the chemical background written in English into Korean, searched prior art to avoid the possibility of dispute between my company and other competitor, etc.
Applying upper experience, I can deal with chemistry/chemical engineering technology documents and patents. And through my experience of business development, I got the basic knowledge of financial term for evaluating new business. So If you assign me jobs in the field of chemical engineering/chemistry or financial (related with business plan), I will make my every effort so that I can contribute to your business.
