Modeling Aggregation and Sedimentation of Nanoparticles in the Aquatic Environment

open access: yesScience of the Total Environment, 2015
With nanoparticles being used more and more in consumer and industrial products it is almost inevitable that they will be released into the aquatic environment. In order to understand the possible environmental risks it is important to understand their behavior in the aquatic environment.

Refinement of the facies model of the north-eastern part of Sakhalin Island for targeting the emplacement of siliceous strata [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2021
Northern Sakhalin is one of the oldest oil and gas producing regions in Russia. Today, the issue of replenishing the resource base of the region is acute. The siliceous strata of the Pilsk Formation are considered as importent petroleum generation level.

Microbial carbonate rocks: composition, structures, textures, mechanisms and environments of formation. Microbiolite formation processes and environments. Article 2

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2022
Introduction. Until relatively recently, all carbonate rocks have been divided into organogenic and chemogenic rocks. The former group includes those half-composed of skeletal remains, thus representing a biological problem.

Dissolution and sedimentation patterns of typical minerals in artificial reservoirs under different environments

open access: yesUnconventional Resources, 2022
The injection of circulating fluids (usually water) is the predominant means of heat extraction in an enhanced geothermal system (EGS); however, the additional injection of circulating fluids can cause a water-rock reaction with a dry thermal rock mass ...

Settlement prediction model of slurry suspension based on sedimentation rate attenuation

open access: yesWater Science and Engineering, 2012
This paper introduces a slurry suspension settlement prediction model for cohesive sediment in a still water environment. With no sediment input and a still water environment condition, control forces between settling particles are significantly ...
