[ 1 ] - Photocatalytic Reduction of CO2 to Formaldehyde: Role of Heterogeneous Photocatalytic Reactions in Origin of Life Hypothesis
Photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (FeS, FeS/FeS2, NiO and TiO2). The reaction was carried out in continues flow of CO2 gas bubbled into the reactor. Semiconductor photocatalysts were characterized by X-Ray diffraction (XRD) and Diffuse Reflectance Spectroscopic (DRS) methods. Sulfide ion was used as hole scavenger. T...
[ 2 ] - Formation and stability of organic layers around inorganic particles in aqueous media: an introduction to origin of life
Formation of non bonded organic layer around inorganic particles like iron sulfide and zeolites, was hypothesized as starting point for one of the possible mechanisms of the origin of life on earth. In this study, the general circumstances needed for creation of such organic layer was investigated. An aliphatic hydrocarbon (hexane), an aromatic hydrocarbon (toluene), an alcohol (n-octanol) and ...

[ 4 ] - شبیه سازی دینامیک مولکولی جذب تری بیس فنول A دی گلیسیدیل اتر بر روی مونت موریلونیت
در این مطالعه، از روش دینامیک مولکولی برای بررسی لایه نشانی شش رشته الیگومر تری بیس فنول A دی گلیسیدیل اتر بر روی مونت موریلونیت در سه دمای 298، 323 و 348 کلوین استفاده شد. در آغاز فرایند فاصلۀ بین رشته های الیگومر با سطح مونت موریلونیت بیش از فاصلۀ قطع پتانسیل انتخاب شد اما فاصلۀ رشته ها از همدیگر کم تر از فاصلۀ قطع پتانسیل بود. با آغاز شبیه سازی رشته های بر روی سط...
