Carbon Nanoparticles-Decorated Carbon Nanotubes [PDF]

open access: yesScientific Reports, 2020
AbstractMulti walled carbon nanotubes (MWCNTs) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. Carbon nanospheres and MWCNTs were mixed by equal mass ratios for different durations. The products were characterized by Raman spectroscopy, thermal gravimetric analysis, nanoscanning electron microscopy, transmission ...

Impact of facies and diagenetic variability on permeability and fluid flow in an oolitic grainstone—Pleistocene Miami Oolite

open access: yesThe Depositional Record, 2020
The Miami Oolite of South Florida is representative of a grainstone‐rich carbonate unit that has been surficially karsted, and therefore may be considered as an analogue for subsurface reservoirs/aquifers with ‘high’ permeability extremes.

Reservoir characteristics and genesis of the Ordovician M54−1a in the central and eastern parts of the Ordos Basin, China

open access: yesJournal of Natural Gas Geoscience, 2020
M54−1a is a new natural gas exploration target of the Ordovician in the Ordos Basin and is expected to have large-scale reserves and a production increasing area after M51 and M52 weathering crust gas reservoir.

Experimental simulation of dissolution law and porosity evolution of carbonate rock

open access: yesPetroleum Exploration and Development, 2016
Experiments of acetic acid (initial 0.2%) with porous dolostone, fractured-porous-vuggy dolostone, porous limestone and fractured limestone were done in a continuous flow diagenesis simulation system to find out the controlling factor of dissolution and ...

Verification of a large-band metamaterial absorber and its application in the measurement of thermal properties of clothing fabrics

open access: yesMaterials Research Express, 2022
The development and application of smart fabrics is a research hotspots in clothing fabrics. Accurately measuring the thermal conductivity of clothing fabric samples is an important basis for developing corresponding products.

Indigenous microbial communities as catalysts for early marine cements: An in vitro study

open access: yesThe Depositional Record, 2023
Early marine cementation is a fundamental process for many characteristics of carbonates, like the stabilisation of steep slopes. The genesis of early cements is often attributed to physicochemical processes but there is evidence for microbial mediation.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

The multidrug and toxin extrusion (MATE) transporter DTX51 antagonizes non‐cell‐autonomous HLS1–AMP1 signaling in a region‐specific manner

open access: yesFEBS Letters, EarlyView.
The Arabidopsis mutants hls1 hlh1 and amp1 lamp1 exhibit pleiotropic developmental phenotypes. Although the functions of the causative genes remain unclear, they act in the same genetic pathway and are thought to generate non‐cell‐autonomous signals.

Types, characteristics, origin and exploration significance of reef-shoal reservoirs: A case study of Tarim Basin, NW China and Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2014
Taking reef-shoal bodies developed in multiple formations in the Tarim and Sichuan Basins as examples, this paper examines the origin of pores and heterogeneity of different types of reef-shoal reservoirs, and tries to find out the distribution rules of ...
