文摘Electrocatalysis offers efficient and targeted conversion of monomers derived from waste polyester plastics to chemical products under ambient temperature and pressure conditions.This review provides analysis of research on electrochemical upgrading of monomers derived from waste polyester plastics published from2021 to present.Factors for assessing upgrading of waste polyester plastics include alkaline hydrolysis pretreatment,indices of electrochemical reaction process(activity,stability,and techno-economic a nalysis),separation,and product recovery.Types of depolymerization monomers and their value-added products are summarized along with electrocatalytic mechanisms and reaction pathways.Notably,cathode coupled reactions offer significant value for anodic waste plastic oxidation during electrolysis processes.Development of bifunctional electrocatalysts can reduce the cost of coupled systems and complexity of the electrolyzer.Upgrading and recycling of waste plastic monomers using electrocatalytic technology should undergo downstream processing to form high-value products containing C-N and C-S derived functional groups obtained from depolymerized monomers,Electrochemical conversion and upgrading of monomers derived from waste polyester plastics can contribute to industrialization and global economies and help to realize environmental sustainability.

文摘In China,electric vehicle(EV)fast-charging power has quadrupled in the past five years,progressing toward 10-minute ultrafast charging.This rapid increase raises concerns about the impact on the power grid including increased peak power demand and the need for substantial upgrades to power infrastruc-ture.Here,we introduce an integrated model to assess fast and ultrafast charging impacts for represen-tative charging stations in China,combining real-world charging patterns and detailed station optimization models.We find that larger stations with 12 or more chargers experience modest peak power increases of less than 30%when fast-charging power is doubled,primarily because shorter charg-ing sessions are less likely to overlap.For more typical stations(e.g.,8-9 chargers and 120 kW·charger^(−1)),upgrading chargers to 350-550 kW while allowing managed dynamic waiting strategies(of∼1 minute)can reduce overall charging times to∼9 minutes.At stations,deploying battery storage and/or expanding transformers can help manage future increases in station loads,yet the primary device cost of the former is∼4 times higher than that of the latter.Our results offer insights for charging infrastructure planning,EV-grid interactions,and associated policymaking.
文摘To satisfy the increasing global energy demand,while searching for new energy sources,it’s important to take a closer look at the resources already at our disposal and optimize their use.This comprehensive review explores the evolving landscape of unconventional oil resources,focusing on the environmental and economic implica-tions of bitumen partial upgrading technologies,particularly within the Canadian context.With over 55%of the world’s oil reserves comprising of unconventional oil,which includes extra-heavy oil and oil sand bitumen,there is a growing trend to shift from traditional oil sources to these abundant yet under-utilized reserves.This review delves into the challenges and advancements in bitumen partial upgrading,highlighting the latest technologies in thermal cracking,hydrocracking,catalytic cracking,and innovative methods like surfactant integration,cavi-tation,microwave,and plasma-assisted upgrading.It also discusses the environmental implications and eco-nomic feasibility of these technologies,emphasizing the necessity for sustainable and cost-effective solutions at petroleum field sites.Furthermore,the report introduces the transformative concept of Bitumen Beyond Com-bustion(BBC),which explores the non-combustion uses of bitumen and its asphaltene fraction in manufacturing high-value carbon-based products.These novel approaches align with global sustainability goals,offering the potential for significant reductions in greenhouse gas emissions and new routes to diversify the economic ap-plications of bitumen.The review then concludes with an assessment of current challenges and future research directions,advocating for a balanced approach that harmonizes technological innovation,environmental stewardship,and economic viability in the field of bitumen upgrading.
文摘The next generation of synchrotron radiation light sources features extremely low emittance,enabling the generation of synchrotron radiation with significantly higher brilliance,which facilitates the exploration of matter at smaller scales.However,the extremely low emittance results in stronger sextupole magnet strengths,leading to high natural chromaticity.This necessitates the use of sextupole magnets to correct the natural chromaticity.For the Shanghai Synchrotron Radiation Facility Upgrade(SSRF-U),a lattice was designed for the storage ring that can achieve an ultra-low natural emittance of 72.2 pm·rad at the beam energy of 3.5 GeV.However,the significant detuning effects,driven by high second-order resonant driving terms due to strong sextupoles,will degrade the performance of the facility.To resolve this issue,installation of octupoles in the SSRF-U storage ring has been planned.This paper presents the study results on configuration selection and optimization method for the octupoles.An optimal solution for the SSRF-U storage ring was obtained to effectively mitigate the amplitude-dependent tune shift and the second-order chromaticity,consequently leading to an increased dynamic aperture(DA),momentum acceptance(MA),and reduced sensitivity to magnetic field errors.
