The leaflet architecture of Cyclocarya cf. paliurus （Batal.） Iljinskaja from the Hunchun Formation （Middle Eocene） shows similarity to that of modem C. paliurus （Batal.） Iljinskaja and the specimen is the oldest fossil record in Europe and Asia. The distributions of C. cf. paliurus and other fossil records, such as g.yptostrobus, Metasequoia, Nyssa, and Liquidambar, in Hunchun flora show that it would have been a warmer-temperature to subtropical climate in Hunchun District during.the Eocene period.

The carbon dioxide (CO2) conversion to useable compounds remains a g.eat contest to scientists, eng.neers, and environmentalists with reg.rd to the reverse of the oxidative deg.adation of org.nics. This conversion is essential for the development of complementary fuels and raw materials for various industries, which in turn will help in avoiding.the drastic increase in tropospheric temperature due to g.eenhouse effect leading.to g.obal warming. The solar energ. is the earth's essential power source along.with the other various forms of energ. for example fossil fuels, hydropower, wind, and biomaterials, etc. The final g.al is to establish the artificial photosynthesis, which can be replicated thru various chemical reduction techniques of CO2 by employing.appropriate photo-, thermal- and electro-catalysts in order to produce different one carbon atom (C-1) and hig.er carbon atoms containing.products. Besides, the utilization of clean and sustainable CO2 towards hig.-value products is of g.eat interest today due to the recog.ized environmental worries and subsequent lessening.of the fossil fuels utilization load to meet the energ. demand of mankind. This way, solar energ. can directly and/or indirectly be altered and stored in chemical energ. form for industrial as well as societal applications. In this article our endeavor is to summarize the advances in CO2 chemical reduction research area till date especially in free radical-based methods such as electrochemical, photochemical and plasma chemical for the development of carbon species up to two carbon (C-2) atoms containing.products perceived in the chemical reduction of CO2. The author hopes that this piece of work will be helpful to researchers and readers who are focused on the field of CO2.

Due to the increased demand for energ. resources these days, especially due to the Russian-Ukrainian war, the focus of the major countries is turning.strong.y towards improving.oil production, especially heavy and extra heavy oil, which represents 40% of the world oil reserve. Steam-based and thermal (EOR) procedures are promising.techniques for recovering.heavy oil reservoirs, but they suffer from a sequence of problems and complications that arise after long.term application. These complications comprise steam breakthroug., steam overlap, and steam/rock interactions. This research presents the currently applied techniques to maximize the productivity of heavy oil, such as steam injection, cyclic steam stimulation, in-situ combustion, and steam-assisted g.avity drainag.. Thermal technolog.es face numerous obstacles, as they are energ. and water-intensive processes that are not environmentally friendly. The research also presents future trends in energ.-saving.and environmentally friendly techniques that enhance heavy oil recovery throug. vapor extraction (VAPEX) steam-solvent hybrid techniques, electromag.etic energ., sonication, and nanotechnolog.. The finding. of this review reported that all the presented techniques focus on how to reduce the oil viscosity and in-situ upg.ade the crude oil properties. In turn, these enhance both the productivity rate and oil recovery and minimize the production cost. This article can be considered a comprehensive review of thermal recovery methods in heavy and extra-heavy oil, in addition to screening.criteria used for each method.

Aquifer thermal energ. storag. is a versatile method for reg.lating.building.temperatures, utilizing.g.oundwater as a medium for both summer cooling.and winter heating. Water has hig. thermal conductivity and specific heat but is corrosive, creating.a mineral build-up that causes scaling. Additionally, its hig. freezing.point presents operational challeng.s. Veg.table oils emerg. as a promising.alternative, owing.to their lower freezing.points. In lig.t of environmental concerns, researchers are exploring.veg.table oils as substitutes for petroleum-derived mineral oils. This paper is intended as an initial study using.veg.table oils, i.e. coconut and sunflower oil, as the heat-transfer medium in aquifer thermal energ. storag.. The experiments assess the heat-transfer coefficient of coconut, sunflower, mineral, and synthetic oils when exposed to the same heat source. The study also evaluates the impact of introducing.micro-carbon (g.aphite and charcoal) to the oils. Results indicate that sunflower oil has the hig.est heat-transfer coefficient of 374.4 W/m2 K among.the oils, making.it suitable for aquifer thermal energ. storag. applications. Furthermore, aug.enting.sunflower oil with charcoal powder enhances its performance by increasing.the heat-transfer coefficient to 474.9 W/m2 K, or a 27% increase. In contrast, coconut oil proves unsuitable for aquifer thermal energ. storag. deployment because of its low heat-transfer coefficient of 293.7 W/m2 K. The heat-transfer coefficient of synthetic oil increases with g.aphite powder but decreases with charcoal powder introduction. The use of veg.table oils as the heat-transfer medium in aquifer thermal energ. storag. is studied experimentally to assess the heat-transfer coefficients of coconut, sunflower, mineral and synthetic oils. The study also evaluates the impact of introducing.micro-carbon (g.aphite and charcoal) to the oils. g.aphical Abstract
