        성서 번역에서 인지적 이슈들 - 인간 경험의 정황 안에 있는 성서 본문 -

        대니얼 쇼(R. Daniel Shaw),대니 딜로우치(Danny DeLoach),조나단 그라임스(Jonathan Grimes),존 루치비아(John O. Luchivia),쉐릴 실저(Sheryl Silzer),에이미 웨스트(Amy West),조재천(번역자) 대한성서공회 2021 성경원문연구 Vol.- No.48

        인지 연구는 정신-뇌와 인간 행동 간의 연관성을 탐구하는 모든 분야에 영향을 미친다. 당연하게도 성서 번역은 다분야적 작업으로서 인지적 과정의 영향을 받는다. 한편으로 특정 성서 본문에 의도된 의미, 다른 한편으로 특정 민족 집단의 정황에 기반해서 추론된 의미들에 관해 성서 번역자는 무엇을 알아야 하는가? 이질적이지만 상호 작용할 수밖에 없는 이 두 환경들이 혼합됨으로써 성서 본문의 내용으로부터 나오는 지식의 총화를 투영해 낼 수 있는가? 공저자들은 번역과 인간 행동의 관계를 반영하는 다양한 인지적 과정을 탐구한다. 우리의 목표는 번역된 성서 본문이 어떻게 인간의 인지 활동과 어우러지면서 특정한 정황에서의 행동에 영향을 미치는지를 보이는 것이다.

        Study on the Influence of Nickel Additions on AA7020 Formability Under Superplastic Forming Like Conditions

        S. Taylor,V. Janik,R. Grimes,R. Dashwood 대한금속·재료학회 2023 METALS AND MATERIALS International Vol.29 No.9

        This study set out to look at the influence of nickel additions on a commercially available AA7020 to understand the impactof the resultant intermetallics on recrystallization, formability and material strength. Elevated temperature tensile testingacross a range of strain rates (5 × 10−4 s−1 × 10−1 s−1) and three temperatures (450− 500 °C) to compare material ductilityfollowed by gas bulge testing at 475 °C and two gas pressures to investigate formability in a test closer to industrial formingconditions. Material strength was established using standard tensile testing, and EBSD used to understand the microstructuralevolution of the materials. It was seen that the nickel additions increased ductility of the material across all test conditions,coupled with increasing the material strength. This was achieved due to the formation of nickel rich intermetallics whichrefine the microstructure during pre-heating through particle stimulated nucleation and subsequently improve strength throughprecipitation hardening in aging treatments.

      • High-rate solar-light photoconversion of CO<sub>2</sub> to fuel: controllable transformation from C<sub>1</sub> to C<sub>2</sub> products

        Sorcar, Saurav,Thompson, Jamie,Hwang, Yunju,Park, Young Ho,Majima, Tetsuro,Grimes, Craig A.,Durrant, James R.,In, Su-Il The Royal Society of Chemistry 2018 Energy & environmental science Vol.11 No.11

        <P>The production of solar fuels offers a viable pathway for reducing atmospheric CO2 concentrations and the storage and transport of solar energy. While photoconversion of CO2 into C1 hydrocarbon products, notably methane (CH4), is known, the ability to directly achieve significant quantities of higher-order hydrocarbons represents an important step towards practical implementation of solar fuel technologies. We describe an efficient, stable, and readily synthesized CO2-reduction photocatalyst, Pt-sensitized graphene-wrapped defect-induced blue-coloured titania, that produces a record high combined photocatalytic yield of ethane (C2H6) and methane. For the first time, a systematic ultraviolet photoelectron spectroscopy study on the mechanism underlying ethane formation indicates that the process is dependent upon upward band bending at the reduced blue-titania/graphene interface. Furthermore, transient absorption spectroscopy indicates photogenerated holes move into the graphene while electrons accumulate on the Ti<SUP>3+</SUP> sites, a phenomenon contradicting prior assumptions that graphene acts as an electron extractor. We find that both mechanisms serve to enhance multielectron transfer processes that generate ˙CH3. Utilizing a continuous flow-through (CO2, H2O) photoreactor, over the course of multiple 7 h runs approximate totals of 77 μmol g<SUP>−1</SUP> C2H6 and 259 μmol g<SUP>−1</SUP> CH4 are obtained under one sun AM 1.5G illumination. The photocatalyst exhibits an apparent quantum yield of 7.9%, 5.2% CH4 and 2.7% C2H6, and stable photocatalytic performance over the test duration of 42 h. The carbon source for both products is verified using <SUP>13</SUP>CO2 isotopic experiments.</P>

      • Photocatalytic conversion of CO<sub>2</sub> to hydrocarbon fuel using carbon and nitrogen co-doped sodium titanate nanotubes

        Parayil, S.K.,Razzaq, A.,Park, S.M.,Kim, H.R.,Grimes, C.A.,In, S.I. Elsevier 2015 Applied Catalysis A Vol.498 No.-

        Carbon and nitrogen co-doped sodium titanate nanotubes (C,N-TNT) active under simulated solar light are synthesized by a simple two-step process comprising an alkaline hydrothermal technique followed by calcination. Different samples of C,N-TNT with varied dopant concentrations are achieved by changing the amount of urea as a nitrogen and carbon dopants. The photocatalysts are characterized using numerous experimental techniques, and under simulated solar light investigated for the photocatalytic conversion of CO<SUB>2</SUB> and water vapor to CH<SUB>4</SUB>. The C,N-TNT sample with an intermediate doping concentration yields the maximum methane yield of 9.75μmol/gh. The key factors contributing in the improvement of photocatalyst performance includes light absorption, surface area and Na<SUP>+</SUP> ions concentration in TNT acting as CO<SUB>2</SUB> adsorption site and photogenerated electrons recombination centers. The higher doping levels results in lower specific surface areas leading to decrease in photocatalyst performance. Our results suggest co-doping of nanostructured photocatalysts is an excellent pathway for improving textural and photocatalytic properties for the respective application domain.
