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 ...

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]

open access: yes, 2004
The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

Application of new dating and temperature-measuring technologies in study of strike-slip fault-controlled reservoirs and hydrocarbon accumulation: A case study of Ordovician strata in non-foreland area of Tarim Basin, NW China

open access: yesPetroleum Exploration and Development
Focusing on the geochronological issues related to the matching relationship between the strike-slip fault activity and the stages of hydrocarbon generation, reservoir formation, and hydrocarbon accumulation, this study aims to quantitatively constrain ...

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.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Paleoceanography of the eastern equatorial Pacific during the Neogene: Synthesis of Leg 138 drilling results [PDF]

open access: yes, 1995
The primary objective of Leg 138 was to provide detailed information about the ocean\u27s response to global climate change during the Neogene. Two north-south transects were drilled (95° and 110°W) within the region of equatorial divergence-driven ...

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 ...

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.

Formations of calcium carbonate minerals by bacteria and its multiple applications

open access: yesSpringerPlus, 2016
Biomineralization is a naturally occurring process in living organisms. In this review, we discuss microbially induced calcium carbonate precipitation (MICP) in detail.

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...
