Molecules, Vol. 28, Pages 6766: Oil-Soluble Exogenous Catalysts and Reservoir Minerals Synergistically Catalyze the Aquathermolysis of Heavy Oil
hao Gang Chen Oil is the “blood” and economic lifeblood of modern industry, but traditional light crude oil has been over-consumed, and it has been difficult to meet human demand for energy, so the exploitation of heavy oil is particularly important. In this paper, an oil-soluble catalyst was synthesized to catalyze the pyrolysis reaction of heavy oil in collaboration with reservoir minerals, so as to achieve efficient viscosity reduction of heavy oil and reduce production costs. The experimental results showed that Zn(II)O + K had the best synergistic viscosity reduction effect after the ...

Building Block-inspired Hybrid Perovskite Derivatives for Ferroelectric Channel Layers with Gate-Tunable Memory Behavior
Angew Chem Int Ed Engl. 2023 Sep 21:e202309416. doi: 10.1002/anie.202309416. Online ahead of print.ABSTRACTFerroelectric photovoltaics driven by spontaneous polarization (Ps) holds a promise for creating the next-generation optoelectronics, spintronics and non-volatile memories. However, photoactive ferroelectrics are quite scarce in single homogeneous phase, owing to the severe Ps fatigue caused by leakage current of photoexcited carriers. Here, through combining inorganic and organic components as building blocks, we constructed a series of ferroelectric semiconductors of 2D hybrid perovskites, (HA)2(MA)n-1PbnBr3n+1 (n =...

“PictureWhat” ??? Super-Human Poison Ivy. What’s Going On?
By MIKE MAGEE Connecticut loves its’ trees. And no town in Connecticut loves its’ trees more than West Hartford, CT. The town borders include an elaborate interconnected reservoir system that does double duty as a focal point for a wide range of nature paths for walkers, runners and cyclists. While walking one path yesterday, I came a tree with the healthiest upward advancing vine I had ever seen. My “PictureThis” app took no time to identify the plant. To my surprise, it was Toxicodendron radicans, known commonly as Poison Ivy. The description didn’t pull punches. It read, “In pop culture, poison ivy ...

Biodegradability enhancement of waste lubricating oil regeneration wastewater using electrocoagulation pretreatment
Environ Sci Pollut Res Int. 2023 Sep 20. doi: 10.1007/s11356-023-29841-7. Online ahead of print.ABSTRACTAs a sustainable management of fossil fuel resources and ecological environment protection, recycling used lubricating oil has received widespread attention. However, large amounts of waste lubricating-oil regeneration wastewater (WLORW) are inevitably produced in the recycling process, and challenges are faced by traditional biological treatment of WLORW. Thus, this study investigated the effectiveness of electrocoagulation (EC) as pretreatment and its removal mechanism. The electrolysis parameters (current density, ini...

Characteristics of dissolved organic matter in point-source wastewaters at a petrochemical plant: Molecular constituents and contributions to the influent of wastewater treatment plant
In this study, DOM in three low-salinity point-source PCWs and four high-salinity point-source PCWs at a typical petrochemical plant were comprehensively characterized at a molecular level. Orbitrap mass spectrometry results indicated that point-source PCWs had diverse DOM constituents tightly related to the corresponding petrochemical processes. Phenols in oily wastewaters (OW), phenols and N-containing compounds in coal partial oxidation wastewater (POXW), and naphthenic acids (NAs) and aromatic acids in crude oil electric desalting unit wastewater (EDW) were characteristic DOM constituents for low-salinity point-source ...

Research on the uranium (VI) reduction by free radicals using UV/formic acid process
This study investigated the use of ultraviolet (UV) light irradiation for the activation of formic acid (FA) to reduce U(VI) in aqueous solutions. The results demonstrated that under UV radiation, FA exhibited a higher U(VI) reduction efficiency than other organic acids, and up to 70% of U(VI) in aqueous solutions was successfully removed. Electron spin resonance and methanol quenching experiments confirmed that U(VI) reduction in the UV/FA process was due to the electron transfer facilitated by FA (HCOOH) and CO2•−. This catalyst-free UV/FA process holds promise for the reduction of U(VI) in leaking water from uranium tailing ponds.

Eosinophilic fasciitis in a young male auto mechanic exposed to organic solvents
We report a case of eosinophilic fasciitis in a teenage auto mechanic who was most likely affected by occupational exposure to organic solvents, including the aromatic hydrocarbons benzene, trimethylbenzene, naphthalene, toluene, and xylene. The patient presented with an 8-month history of painful induration of his extremities and an abnormal gait. A deep excisional biopsy of the fascia was obtained, demonstrating subcutaneous fibrosis with perivascular and interstitial inflammation, with lymphocytes and plasma cells spilling into the sclerosed fascia, and focal fibrinoid necrosis. Treatment was begun with intravenous puls...

Production of extracellular superoxide radical in microorganisms and its environmental implications: A review
Environ Pollut. 2023 Sep 15:122563. doi: 10.1016/j.envpol.2023.122563. Online ahead of print.ABSTRACTExtracellular superoxide radical (O2•-) is ubiquitous in microbial environments and has significant implications for pollutant transformation. Microbial extracellular O2•- can be produced through multiple pathways, including electron leakage from the respiratory electron transport chain (ETC), NADPH oxidation by the transmembrane NADPH oxidase (NOX), and extracellular reactions. Extracellular O2•- significantly influences the geochemical processes of various substances, including toxic metals and refractory organic po...

Modified air-Fenton with MIL-88A for chemical oxygen demand treatment in used coolant oil
In this study, COD treatment of coolant oil was investigated in a metal-organic framework (MOF) with MIL-88A by a modified air-Fenton (MAF) process by varying synthetic coolant oil concentrations (1-5%), pH (3-9), air-flow rate (1-2 L/min), amount of MIL-88A (0.2-1.0 g), and reaction time (30-180 min). The results were analyzed using central composite design (CCD) and response surface methodology (RSM) using Minitab ver. 19. The characteristic MIL-88A was characterized by XRD that showed a spindle-like shape with 2θ at 10.2° and 13.0°. The FTIR spectrum revealed the vibrational frequencies at Fe-O (564 cm-1), C-O (1391 ...
