Influence of shear on rheology of the crude oil treated by flow improver

open access: yesEnergy Reports, 2019
Because the influence of shear on the rheology of waxy crude oil must be considered according to the composition and structure of the waxy crude oil transported via pipeline when a new pipeline is constructed, the risks associated with changes in the ...

Light‐Activatable Nitric Oxide Release via Intramolecular Electron Transfer for Tumor Pyroptosis Induction

open access: yesAdvanced Science, EarlyView.
This work proposes a novel strategy to fabricate unimolecular pyroptosis photoinitiators activated by deep‐red light at low light doses. It relies on a photosensitization mechanism to trigger nitric oxide (NO) release from benzisothiadiazole‐based N‐nitrosanilines without modification of nitro moieties, thereby boosting pyroptosis‐mediated ...

Gasoline and crude oil prices: why the asymmetry? [PDF]

open access: yes
Many consumers complain that gasoline and crude oil prices have an asymmetric relationship in which gasoline prices raise more quickly when crude oil prices are rising than they fall when crude oil prices are falling.

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Economic Assessment of a Crude Oil Hydrotreating Process

open access: yesChemical Engineering Transactions, 2019
This paper presents the economic assessment of a crude oil hydrotreating process with a crude distillation unit. The hydrotreating of crude oil is a novel process that has great economic potential but has not been implemented widely in practice, where ...

A Triple‐Nanoparticle System for Controlled Graphene Nanosheet Stacking: Enabling K/Na‐Ion Battery Anodes with Ultra‐Fast Charging Exceeding Petroleum Vehicle Refueling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Large‐ion (K, Na) battery systems mitigate uneven global lithium distribution, while their ability to attain recharge time shorter than refueling would remove the final barrier for secondary batteries to replace petroleum vehicles. However, their large‐ion chemistry makes ultra‐fast charging an even significant challenge.

Pressure‐Driven Phase Transition Unlocking Unique Eu2+ Luminescence in Li2SrSiO4 for Optical Sensing and White‐LEDs

open access: yesAdvanced Science, EarlyView.
This study demonstrates, for the first time, the use of a large‐format high‐pressure press to modify synthesized Li2SrSiO4:Eu2+,Cs+ phosphors after its preparation. The pressure treatment results in the formation of new materials with distinctive optical properties, opening pathways for the development of advanced LED devices and high‐performance ...
