Abstract:
... Water, energy and food are three essential resources for the socio-economic system, and they are interlinked. The coordination of their internal relations is worth studying. We conduct a coordination evaluation method to assess the water-energy-food nexus (WEF Nexus) in China’s provinces. By combining the coupling model and the coupling coordination model, we measure the comprehensive evaluation i ...

Abstract:
... The rapid development of unconventional oil and gas (O&G) extraction around the world produces a significant amount of wastewater that requires appropriate management and disposal. Produced water (PW) is primarily disposed of through saltwater disposal wells, and other reuse/disposal methods include using PW for hydraulic fracturing, enhanced oil recovery, well drilling, evaporation ponds or seepa ...

Abstract:
... With the growing development of hydropower projects all over the world, the excessive greenhouse gas (GHG) emissions from increasing reservoirs have drawn public concern. While precise evaluations of GHG emissions are urgently needed, the widely applied methods including floating chamber (FC) method and thin boundary layer (TBL) method are unsatisfactory. In this paper, a new methodology of estima ...
... Ultra-light elastic carbon aerogels with high compressibility have broad application prospects in wearable devices. Especially, they are ideal materials for fabricating flexible piezoresistive sensors. In this paper, an ultra-light carbon aerogel was successfully fabricated using freeze-drying and carbonization of the solution containing chitosan (CS), polyimide (PI), and FeCl₃·6H₂O. Owing to the ...
... Nylons are important polyamide (PA) materials that can be polymerized from different monomers. Bio-based nylon monomers are traditionally obtained through chemical conversion from vegetable oils, but they can be more sustainably obtained through multienzymatic catalysis. For large-scale application of this process, enzyme engineering and process innovation must be combined. ...

Abstract:
... Urban heat island (UHI) has a great influence on human wellbeing in urban areas. Previous studies have investigated impact on environment, ecosystem, and human health of UHI. To investigate economic impact of UHI is a lack of research. In this study, spatial-econometric hedonic housing price models are developed for estimating the marginal value of summer UHI in Beijing, China. The results showed ...
... The flexible hydrogel sensors in the field of artificial intelligence have been widely concerned, which could be applied in medical monitoring, human motion detection, and intelligent robots. However, the integration of the synergistic properties of excellent mechanical properties, temperature sensitivity, adhesion ability and self-healing ability for preparation of hydrogel-type strain sensor is ...
... Conductive hydrogels have the mechanical properties and the electronic transport properties of conductive polymers, which have been widely used in the fields of energy storage and bioelectronics. However, the rigidity and brittleness of conductive polymers hinder the long-term stability of hydrogels and limit its application in new flexible electronic devices. It is a high challenging task to prep ...
... Yarrowia lipolytica is recognized as an excellent non-conventional yeast in the field of biomanufacturing, where it is used as a host to produce oleochemicals, terpenes, organic acids, polyols and recombinant proteins. Consequently, metabolic engineering of this yeast is becoming increasingly popular to advance it as a superior biomanufacturing platform, of which promoters are the most basic eleme ...

Abstract:
... OBJECTIVE: To investigate the effect of aromatherapy on sleep quality in cancer patients. METHODS: Published literature on the effect of aromatherapy in cancer patients with sleep disorders in the form of randomized controlled trials (RCTs) were systematically retrieved and screened from PubMed, Cochrane Library, Embase, CBM, CNKI, VIP, and Wanfang databases from inception to November 2021. The me ...

Abstract:
... Aromaticity is a fundamental and important concept in chemistry, and usually, the enhancement of aromaticity brings additional thermodynamic stability to a compound. Moreover, since radicals can act as intermediates in chemical reactions, they have attracted considerable attention from both experimental and theoretical chemists for a long time. However, it remains unclear whether there is a relati ...
... Unusual fatty acids with special carbon chain length or functional groups have been extensively used in the chemical, material, nutraceutical, and pharmaceutical industries. The traditional sources of these valuable fatty acids mainly include animal or plant extraction and chemical synthesis, which are unsustainable and may cause considerable environmental issues. The advancement of synthetic biol ...
... Uranium extraction from seawater is regarded as the most promising strategy for solving the concerns regarding the increasing demands of the nuclear industry. Inspired by the functional proteins of natural biological entities like bacteria and proteins that can efficiently capture uranium, we have developed water-insoluble protein-based adsorbents via a one-step amyloid-like assembly process. This ...
... Reed is a promising biorenewable energy source given its ability to grow rapidly under environmentally challenging conditions. Pretreatment of reed by ball-milling in the presence of p-toluenesulfonic acid (p-TsOH) led to a significant reduction in hemicellulose (78%) and lignin (67%) content. After this pre-treatment, enzymatic hydrolysis of the residue led to a glucose content of 12.0 g/L. The e ...
... In this work, we synthesized a novel mono-atomically dispersed Fe-based catalyst supported on graphitic carbon nitride through a nimble, green and low-priced coordination-precipitation method. Under optimization conditions, a 98% yield of 2,5-diformylfuran (DFF) was obtained from the oxidation of 5-hydroxymethylfurfural (HMF) or the two-step conversion of fructose. We unveiled that the Fe³⁺ specie ...

Abstract:
... This paper proposes a new screening procedure for the ultrahigh dimensional data with a categorical response. By exploiting the group structure among predictors, a new partition-based screening approach is developed via the reproducing kernel Hilbert space (RKHS) embeddings in the maximum mean discrepancy framework. Consequently, the new method is able to identify the influential group of predicto ...
