Abstract	Promoted by carbon neutrality and solid iste policies, iron- and steelmaking iste slag (ISWS)-based glass-ceramics have drawn attention because of their contribution to achieving the net-zero carbon emissions goal for the iron- and steelmaking industry. However, a holistic estimation of the preparation, property and GHG (greenhouse gas) emission abatement of ISWS-based glass-ceramics is still under exploration. In this paper, research progress on preparing glass-ceramics from ISWS discharged from the traditional iron- and steelmaking industry is reviewed. Then, the influence of ISWS’s chemical characteristics on the preparation of glass-ceramics and the products’ performance are discussed. In addition, the potential of GHG emission reduction related to the promotion of ISWS-based glass-ceramics is measured. It is found that ISWS-based glass-ceramics can avoid 0.87–0.91 tons of CO 2 emissions compared to primary resource routes. A scenario simulation is also conducted. If the technology could be fully applied in the ironmaking and steelmaking industries, the results suggest that 2.07 and 0.67 tons of indirect CO 2 reductions can be achieved for each ton of crude steel production from blast furnace–basic oxygen furnace (BF-BOF) and electric arc furnace (EAF) routes, respectively. Finally, a “dual promotion” economic mode based on national policy orientation and the high demands on metallurgical iste slag (MWS)-based glass-ceramics is proposed, and the application prospects of MWS-based glass-ceramics are examined. These application prospects will deepen the fundamental understanding of glass-ceramic properties and enable them to be compounded with other functional materials in various new technologies.

Abstract	We report the suppression of diagonal signals in (H)N(H)(H)NH spectra through the use of untransferred signals (orphan spin operators) from cross polarization steps. In contrast to most diagonal suppression methods, there is no loss of sensitivity for cross-peaks at ultrafast MAS. For the proton-detected (H)N(H)(H)NH sequence, recorded with 55 kHz MAS, we observed approximately 50% suppression of diagonal signal after 1.08 ms mixing. A similar construction for CHHC spectra at 13 kHz MAS suppresses both the diagonal and cross-peaks, and simulations suggest proton assisted recoupling (PAR) is responsible. Alternatively, a combined PAR+CHHC spectrum can be recorded.

Abstract	The environmental impact from the waste disposal has been widely concerned around the world. The conversion of wastes to useful resources is important for the sustainable society. As a typical family of wastes, biomass materials basically composed of collagen, protein and lignin are considered as useful resources for recycle and reuse. In recent years, the development of carbon material derived from biomasses, such as plants, crops, animals and their application in electrochemical energy storage have attracted extensive attention. Through the selection of the appropriate biomass, the optimization of the activation method and the control of the pyrolysis temperatures, carbon materials with desired features, such as high-specific surface area, variable porous framework, and controllable heteroatom-doping have been fabricated. Herein, this review summarized the preparation methods, morphologies, heteroatoms doping in the plant/animal-derived carbonaceous materials, and their application as electrode materials for secondary batteries and supercapacitors, and as electrode support for lithium-sulfur batteries. The challenges and prospects for the controllable synthesis and large-scale application of biomass-derived carbonaceous materials have also been outlooked.

Abstract	The construction of bridge is a complex process and involves diverse energy emission-intensive materials. The evaluation of environmental impacts on the basis of life cycle assessment (LCA) is a recognised technique to find the scope of impact mitigation and save resources. However, the studies on the LCA of bridges are rare and lack assessment on the impact of public transportation during bridge construction. The purpose of this study was to develop an integrated exergy-based LCA model for assessing the environmental sustainability of bridges by investigating their environmental impacts and exergy footprint. The proposed exergy-based LCA model consists of three principal assessment models, namely, the environmental impact of energy consumption, pollutant discharge, and resource consumption. The proposed model was then exemplified with a highway bridge as a case study. The results found that the environmental impact in the raw material production and processing stage was the largest, followed by the construction stage and the operation and maintenance stage at second and third place, respectively. The findings of this study can contribute to mitigating the environmental impacts of bridge construction, and the assessment approach can be adopted to guide the environmental impact evaluation for other types of civil constructions globally.

Abstract	Cervi Cornu is the ossified antler, or the base antler that falls off in the spring of the following year after the pilose antler is sawn off from Cervus elaphus or C. nippon, as a precious traditional Chinese medicine, has been recognized for its medicinal value and widely used in clinical practice. However, the origins of Cervi Cornu are miscellaneous, and Cervi Cornu is even mixed with adulterants in the market. Currently, there is a shortage of ways to identify Cervi Cornu and no standard to control the quality of Cervi Cornu. So it is valuable to develop a way to effectively identify Cervi Cornu from the adulterants. In this study, the differences in the mitochondrial barcode cytochrome b(Cytb) gene sequences of C. elaphus, C. nippon and their related species were compared and the specific single nucleotide polymorphism(SNP) sites on the Cytb sequences of Cervi Cornu were screened out. According to the screened SNPs, Cervi Cornu-specific primers dishmy-F and dishmy-R were designed. The PCR system was established and optimized, and the tolerance and feasibility of Taq polymerases and PCR systems affecting the repeatability of the PCR method were investigated. The amplification products of C. elaphus and C. nippon were digested using the restriction enzyme MseⅠ. The results showed that after electrophoresis of the product from PCR with the annealing temperature of 56 ℃ and 35 cycles, a single specific band at about 100 bp was observed for C. elaphus samples, and the product of C. elaphus samples was 60 bp shorter than that of C. nippon samples. There was no band for adulterants from other similar species such as Alces alces, Rangifer tarandus, Odocoileus virginianus, O. hemionus, Cap-reolus pygargus, Przewalskium albirostis and negative controls. The polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) method established in this study can quickly and accurately identify Cervi Cornu originated from C. elaphus in crude drugs, standard decoctions, and formula granules, and distinguish the origins of Cervi Cornu products, i.e., C. nippon and similar species. This study can be a reference for other studies on the quality standard of other formula granules of traditional Chinese medicines.

Abstract	The conservation of the ecosystem in the Yellow River source region (YRSR) has become a crucial national strategy in China, emphasizing the need for evaluating ecosystem integrity to identify priority conservation areas (PCAs). Current research has primarily employed a limited number of indicators or a single dimension to assess ecosystem integrity, which may overlook comprehensive considerations required for effective conservation planning. To address this, a multidimensional approach was adopted in this study to evaluate ecosystem integrity, incorporating three dimensions: biological diversity, ecosystem function, and stress components. The MaxEnt and Fragstats models were employed to create an ecosystem integrity map and Marxan was used to identify priority conservation areas within the YRSR. Our results showed that (1) the index of ecosystem integrity gradually declined from east to west, consistent with the spatial distribution of biodiversity and ecosystem function, whereas the stress component exhibits a decreasing trend from northeast to southwest. (2) the priority protected areas were distributed in Maduo, Ruoergai, Maqu, Maqin, Henan, Gande, and Jiuzhi Counties. Furthermore, to address existing protection gaps and enhance connectivity, it was recommended to incorporate an additional 27,644 km2 of southwest and central YRSR into the PCAs. Overall, the study offered practical recommendations for the conservation of the ecosystem in the YRSR. In addition, the method of PCAs determination in this study could provide a reference for the government’s growing nature conservation affairs, which will contribute to sustainable development.
