This process was carried out in a 3000 cm<sup>3</sup> semibatch pyrolysis reactor; the systematic experimental design involved catalytic copyrolysis by varying the operating parameters of the pyrolysis temperature (400–500 °C), the inert nitrogen flow rate (25–150 mL/min), and the ratio of blended ULO/UCO from 0.9:0.1 to 0.2:0.8. The advantage of Ni modified to activated carbon is that it is considered a stronger acid solid catalyst with an extraordinary pore structure, which undergoes catalytic copyrolysis; the concentration of the Ni metal doped into the AC catalyst was 3–10 wt %, and the catalyst loading on the feedstocks (5–20 wt % of Ni/AC catalyst) was performed. The effects of the conversion of ULO/UCO on the yield and physicochemical properties of copyrolysis oil and the product distribution according to ASTM D86 were investigated. The 5 wt % Ni doped into the AC catalyst is related to the strength of the acid activity that accelerated the conversion of large hydrocarbon compounds to obtain a straight aliphatic hydrocarbon compound, and the Ni/AC catalyst also plays a role in facilitated C–C bond cleavage and bond scission to smaller hydrocarbon compounds. The highest yield of naphtha-like fraction of 25.34 wt % was obtained at the optimal condition of 425 °C, the N<sub>2</sub> carrier flow rate was 50 mL/min, the ULO/UCO ratio was 0.5:0.5, 5 wt % Ni was modified into the AC catalyst, and 5% catalyst was loaded into the feedstock. The synergistic effects of UCO and ULO during copyrolysis also revealed that the H-donor and hydrocarbon radicals of UCO decrease the thermal stability of ULO, whereas the addition of 5 wt % Ni to the AC catalyst, which is relevant to acid activity, is mainly responsible for bond scission, hydrogenation, isomerization, and oligomerization, resulting in the formulation of condensable volatile vapors to maximize the production of straight aliphatic and olefinic hydrocarbon compounds, which can be used as sustainable fuels from the conversion of waste to alternative energy.</p>","PeriodicalId":22,"journal":{"name":"ACS Omega","volume":"10 15","pages":"14699–14722 14699–14722"},"PeriodicalIF":3.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsomega.4c08111","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a self-designed DME–DDP experimental apparatus, oil extraction experiments were conducted on consolidated oil sands samples to simulate the oil sand formations in the Athabasca region in Canada.

The DME–DDP oil extraction process includes two stages, displacement and dissolution–permeation, each contributing to approximately 50% of the total oil recovery. The pressure gradient is the primary factor influencing oil washing efficiency, with higher recovery necessitating slower permeation or extended contact time between DME and crude oil in the formation.

Generally, metal electrodes have high conductivity but very low stretchability, while organic electrodes have high stretchability but lower conductivity than metals. In this paper, metal/organic hybrid electrodes were fabricated on elastic poly(dimethylsiloxane) (PDMS) substrates to take advantage of the high conductivity of metals and the high stretchability of organic semiconductors. Additionally, by prestraining the PDMS substrate, the stretchability of the electrodes was further increased. However, the uniaxially prestrained electrodes produced compressive stresses in the direction perpendicular to the stretching direction due to Poisson’s effect, resulting in many cracks. To solve this problem, biaxial prestrain was introduced to the PDMS substrate. The electrodes fabricated with uniaxial prestrain exhibited a structure with wrinkles aligned in one dimension, whereas the electrodes with biaxial prestrain displayed highly ordered, two-dimensional wrinkle patterns arranged on the electrode surface. The electrodes with biaxial prestrain maintained stable electrical performance even after 200 cycles of stretching at a strain of 50%, withstanding up to 130% strain. Furthermore, of all the poly(3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS)-based electrodes reported so far, our electrode showed the lowest sheet resistance of 0.91 Ω/sq.

Seven organosilanes were selected with different numbers of hydrolyzable groups, alkyl chain lengths, alkyl chain structures, and number of silicon atoms. Contact angle measurements, residual fluid saturations, and capillary pressure curves consistently showed that more hydrolyzable groups create more hydrophobic surfaces.

Given the limitations of conventional treatment methods, recent research has increasingly focused on developing innovative, sustainable, and environmentally friendly solutions to address this pressing issue. This study investigates the potential of <i>Pseudomonas aeruginosa</i> in biological remediation by comparing two textile dyes: the anionic indigo carmine (IC) and the cationic safranine-T (ST). The influence of different initial dye concentrations (50, 100, 150, and 500 mg L<sup>–1</sup>), agitation rates (static vs 125 rpm), and growth medium concentrations (25 vs 50 g L<sup>–1</sup>) was also assessed. It was found that <i>P. aeruginosa</i> achieved &gt;96% decolorization of IC within 8 h under agitation, with a decolorization rate of 60.27 mg L<sup>–1</sup> h<sup>–1</sup>. In contrast, ST showed limited removal (77.2%) only in the lowest dye concentration and highest medium concentration. Agitation consistently enhanced dye removal, with IC likely metabolized as an energy source, while ST removal was attributed to biosorption. Second-order kinetic models best described the decolorization process. These findings highlight the potential of <i>P. aeruginosa</i> as biological resources for efficient, sustainable wastewater treatment, offering a viable alternative to conventional methods and contributing to environmental sustainability. Further optimization of process conditions could broaden its application in industrial effluent management.</p>","PeriodicalId":22,"journal":{"name":"ACS Omega","volume":"10 15","pages":"14676–14686 14676–14686"},"PeriodicalIF":3.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsomega.4c07948","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143854263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
