Two-dimensional(2D) materials have been demonstrated to exhibit unique properties originating from its 2D nature. In recent years, the construction of 2D materials has become a topic of great interest. This article summarizes the recent advance of 2D supramolecular organic frameworks(SOFs) which are homogeneously constructed in solution phase through self-assembly of rationally designed building blocks. These 2D SOFs are soluble and still maintain stable network structures in solutions, which exhibit uniqueness not only in structures but also in properties. In this concise review, the SOFs-related background is briefly introduced firstly, followed by outlining the research progress of soluble 2D SOFs from the perspective of monomer design, assembly, and structural *** article ends with a personal outlook on the future development of this new class of supramolecular polymers.

The mismatch in thermal expansion coefficient between crystalline phase and glass phase can result in large thermal stresses during thermal processing, as well as the low thermal conductivity, which is the most troublesome in the production of the CaO-Al2O3-SiO2 glass-ceramic. CaO content may influence the residual stress in the system. Therefore X-ray diffraction (XRD) ‘sin2ψ’ method was used to calculate the residual stress in samples containing various contents of CaO. The relationship between CaO content and residual stress in CAS system was investigated. Finally reasons causing such residual stress were analyzed.

This paper systematically investigates and compares the petroleum geology elements and oil and gas exploration potential in the deep-water basins along the conjugate passive margins between Morocco in NW Africa and Nova Scotia in Canada. Both the deep-water basins along the passive margin in Morocco and its conjugate passive margin deep-water basin in Nova Scotia have undergone similar multiple stages of tectonic evolution. These conjugate basins both have Jurassic and Cretaceous source rocks;Triassic sandstone, Jurassic–Cretaceous carbonate and sandstone, and Miocene–Pliocene sandstone reservoirs;multiple sets of mudstones and regional Triassic salt as caprocks. These characteristics indicate good hydrocarbon accumulation conditions and exploration prospects. The comparison also reveals that the key exploration targets in the deep-water basins of Morocco should be Tertiary turbidite sandstone reservoirs and Jurassic–Cretaceous sandstone and carbonate reservoirs. Compared with the Scotian Basin, the Morocco deep-water basins may have Paleozoic play potential sourced from the mature Silurian hot shale source rock that extends from the onshore NW African Plate. The prospective exploration targets in the deep-water Scotian Basin should be focused on the Jurassic and Cretaceous deep-water turbidite sandstone reservoirs formed by widely-developed large river systems.

Organic-rich lacustrine shales are widely distributed in China and have significant potential for unconventional shale gas and oil production although the primary factors controlling the deposition of lacustrine shale are disputed. This work clarifies the different characteristics of tectonic evolution and shale among sub-basins in the Bohai Bay Basin in eastern China as a case study by studying basal subsidence, tectonic subsidence rate, basin extensional proportions and shale chemical characteristics. The paper summarizes the correlation between structure and shale deposition, and concludes that tectonic activity is the primary controlling factor for shale development. Episodic tectonic activity controls not only the timing of shale deposition（with the greatest shale deposition occurring primarily during the peak period of basin tectonic activity） but also the spatial distribution of shale（located mainly in areas of maximum subsidence）, the migration pattern of shale（conforming to that of the basin subsidence center）, and shale strata thickness. Tectonic activity also affects the total organic carbon content and organic matter type in shale. When the tectonic activity was the most active and basal subsidence was the maximum, the total organic carbon content of the shale reached its highest value with organic matter type mainly Type I. As tectonic activity weakened, the total organic carbon content decreased, and the organic matter type changed from Type I to Type I-III.

Behavioral gastroenterology is a new interdisciplinary science that explores the influence of unhealthy lifestyles and psychological factors on the digestive system and addresses the prevention,diagnosis,treatment,and rehabilitation of digestive diseases. Moreover,the concept of whole-course intervention with a focus on disease prevention and a new model of integrated therapy based on alterations of lifestyle and psychology are being gradually established. This paradigm may substantively impact the prevention and treatment of digestive diseases.
