The threat to the integrity of pipeline is not only from CO2 corrosion but also due to the presence of organic acid which originates from reservoir and injection of acid during Enhanced Oil Recovery (EOR). Corrosion on pipelines is identified as the most common problem caused by the presence of acetic acid (HAc). Howe…

Atık lastiklerin, inşaat mühendisliğinde kullanımı son zamanlarda önemli bir konu \nhaline gelmiştir. Zeminlerle beraber kullanıldıklarında geoteknik mühendisliği açısından \noldukça olumlu sonuçlar doğurdukları görülmüştür. Yol inşaatlarındaki stabilite ve \noturma problemlerine karşı, istinat ve dolgu duvarlarında i…
En una mezcla de los disolventes tolueno-tetrahidrofurano, se hizo reaccionar YCl3 con Li[N(SiMe3)2] para formar el producto YCl2[N(SiMe3)2](THF)3 (1). Este precursor se hizo reaccionar con los ligandos tridentados: 2,6-bis(3,5-dimetilpirazol-1-ilmetil)piridina y 2,6-bis(indazol-2-ilmetil)piridina obteniéndose los com…
기존에 많이 사용된 반도체 검출기의 분해능은 통계학적 이론으로 그 분해능의 한계가 따른다. 이러한 이유로 최근에 반도체 검출기가 갖는 에너지 분해능의 한계를 뛰어넘는 저온 검출기를 이용하여 다양한 방사성 핵종 분석을 시도하고 있다. 본 논문에서는 2×2×0.05 mm3 크기 금막 흡수체에 입사하는 에너지 때문에 흡수체의 온도가 상승하는 원리를 이용해 241Am 알파 선원의 에너지를 측정하였다. 흡수체의 온도 변화 측정에는 자기양자센서인 Au:Er를 이용하였으며 이는 순수한 Au에 핵스핀이 0 인 168Er을 수백 ppm을 첨가하여 얻은 상자성 합금이다. 알파 입자…
침지형 중공사막 MBR 공정에서는 중공사막 Dead-end 방식의 중공사막 모듈이 주로 사용되고 있으나 MLSS 농도가 높은 경우에 중공사막 모듈 내부에 슬러지가 축적되어 막 오염이 급속히 증가한다는 문제점이 있다. 침지형 중공사막 MBR 공정에서 막 모듈 형태에 따른 막 오염 특성을 파악하기 위해서 모듈의 형태를 End-free와 Dead-end 형태의 막 모듈로 제작하여 막 모듈 구조변화가 막 오염에 미치는 영향을 조사하였다. 또한 End-free 막 모듈에서 막 밀도를 변화시키면서 막 밀도가 막 오염속도에 미치는 영향을 조사하였고 마지막으로 MLSS의 점도 변…

Metal hydride tends to be an efficient way of hydrogen storage and utilization,and hydrogen storage reactors play an important role in improving the heat and mass transfer performance dramatically.Due to the strong exothermic discrepancies during absorption process,a powerful heat transfer system inside the reactor sh…
A family of ceria-substituted on the A-sites of La0.75Sr0.25-xCexCr0.5Mn0.5O3-δ (x=0,LSCM; x=0.125,LSCCM; x=0.25,LCCM) have been synthesized by the sol-gel process and evaluated as the electrode materials of symmetric solid oxide cells (SFC).The orthorhombic perovskite-type structures are demonstrated using X-ray diff…
The absence of a hydrogen refuelling infrastructure and the problems concerning hydrogen storage,has led to the development of fuel processors able to convert available fuels (hydrocarbons and/or alcohols) into hydrogen rich reformate gas (H2 + CO).The choice of a suitable fuel processor and fuel,during the transition…
استخدمت تقنية كواشف الآثار النووية الصلبة SSNTDs الطويلة الأمد والغير مباشرة لقياس تركيز غازالرادون المنبعث من 40 عينة منتخبة من لباب آبار نفطية في محافظتي واسط وذي قار في العراق ولأعماق مختلفة تراوحت بين (100m-3000m ) عن سطح الأرض. بينت الدراسة إن اقل تركيز لغاز الرادون كان 3208 Bq/m3 ، وان اكبر تركيز كان Bq/m3 24370…
تم استخدام اختبار الدفعةBatch Experiment لإزالة المواد المشعة طبيعية المنشأ (نظائر Ac-228, Pb-214, Bi-214, Pb-212, K-40) من المياه الملوثة الناتجة عن الصناعة النفطية (محطات عزل الغاز في حقل الرميلة الجنوبي/ محافظة البصرة) باستخدام مسحوق البنتونايت. أجريت عدة اختبارات في هذه التجربة لإزالة النظائر المشعة من المياه المل…
Front Cover: The division timing of yeast cells is controlled chemically, as a step towards realization of artificial spores, by encapsulating individual yeast within polymeric multilayers of catechol-grafted polyethyleneimine and hyaluronic acid pairs by the layer-by-layer technique and subsequently cross-linking the…
Fuel cells are ultimately one of the best promising devices that convert the potential energy in the reactants into the electrical energy after steps of sequential electrochemical processes with no hazards up on the environment. This paper presents comprehensive derivation and understanding of the electrochemical reac…
This work report the preparation of environmental-responsive hollow poly(N-isopropylacrylamide) (PNIPAM) microspheres through an improved self-removing template method. The influences of different process parameters including the addition amount of MAA, the content of surfactant sodium dodecyl sulfate (SDS) and dialys…
The domain configurations and local piezoresponse property of the [720]-cut BaTiO3 single crystal and [001]-oriented BaTiO3 crystal were investigated by high-resolution piezoresponse force microscopy. Large differences in their surface topography features, domain configurations and local piezoresponse were found betwe…
