Gray Relational Analysis Optimization for Coalbed Methane Blocks in Complex Conditions Based on a Best Worst and Entropy Method

open access: yesApplied Sciences, 2019
The uncertainty and complexity of the geological parameters of coalbed methane (CBM) reservoirs may result in the assignment of atypical exact values to a whole block.

Contact nucleation: in situ and ex situ observations of surface damaging [PDF]

open access: yes, 1990
To investigate the damaging done to a crystal surface potassium dihydrogen phosphate, KDP and potassium hydrogen phthalate, KAP) due to a crystal-rod contact, both ex situ and in situ experiments were performed and the impact sites studied either using ...

Experimental Study on the Effect of Thermal Shock on Physical and Mechanical Properties of Limestone

open access: yesApplied Sciences, 2023
Thermal shock is the physical process of rapid cooling of a hot object. The physical and mechanical properties of rocks that have undergone thermal shock will change.

SIM-SITU: A Framework for the Faithful Simulation of in-situ Workflows [PDF]

open access: yesarXiv, 2021
The amount of data generated by numerical simulations in various scientific domains such as molecular dynamics, climate modeling, biology, or astrophysics, led to a fundamental redesign of application workflows. The throughput and the capacity of storage subsystems have not evolved as fast as the computing power in extreme-scale supercomputers.

In situ Crosslinking of Nanostructured Block Copolymer Microparticles in Supercritical Carbon Dioxide [PDF]

open access: yes, 2019
We report a novel and facile approach to “fix” the internal nanostructure of block copolymer (BCP) microparticles via in situ crosslinking copolymerisation in dispersion in supercritical CO2 (scCO2).

In-situ vs accreted Milky Way globular clusters: a new classification method and implications for cluster formation [PDF]

open access: yesarXiv, 2023
We present a new scheme for the classification of the in-situ and accreted globular clusters (GCs). The scheme uses total energy $E$ and $z$-component of the orbital angular momentum and is calibrated using [Al/Fe] abundance ratio. We demonstrate that such classification results in the GC populations with distinct spatial, kinematic, and chemical ...

Rapidly self-deoxygenating controlled radical polymerization in water via in situ disproportionation of Cu(i) [PDF]

open access: yes, 2020
Rapidly self-deoxygenating Cu-RDRP in aqueous media is investigated. The disproportionation of Cu(I)/Me6Tren in water towards Cu(II) and highly reactive Cu(0) leads to O2-free reaction environments within the first seconds of the reaction, even when the ...

In situ functionalization of graphene [PDF]

open access: yes2D Materials, 2020
Abstract While the basal plane of graphene is inert, defects in it are centers of chemical activity. An attractive application of such defects is towards controlled functionalization of graphene with foreign molecules. However, the interaction of the defects with reactive environment, such as ambient, decreases the efficiency of ...

Electrochemistry of thin films with operando grazing incidence X-ray scattering: bypassing electrolyte scattering for high fidelity time resolved studies [PDF]

open access: yesarXiv, 2021
Electroactive polymer thin films undergo repeated reversible structural change during operation in electrochemical applications. While synchrotron X-ray scattering is powerful for the characterization of stand-alone and ex-situ organic thin films, in situ structural characterization has been underutilized--in large part due to complications arising ...
