A facile and scalable method is realized for the in situ synthesis of N/S co-doped 3 D porous carbon nanosheet networks (NSPCNNs) as anode materials for sodium-ion batteries. During the synthesis, NaCl is used as a template to prepare porous carbon nanosheet networks. In the resultant architecture, the unique 3 D porous architecture ensures a large specific surface area and fast diffusion paths of both electrons and ions. In addition, the import of N/S produces abundant defects, increased interlayer spacings, more active sites, and high electronic conductivity. The obtained products deliver a high specific capacity and excellent long-term cycling performance, specifically, a capacity of 336.2 mA h g at 0.05 A g , remaining as large as 214.9 mA h g after 2000 charge/discharge cycles at 0.5 A g . This material has great prospects for future applications of scalable, low-cost, and environmentally friendly sodium-ion batteries.

“…For lithium-sulfur battery applications, these C/S composites are able to manipulate 'shuttle effects' for better stability, while larger pores to facilitate ion transportation for improving rate performance. To date, all kinds of biomass precursors, such as pig bone [142], fish scales [66], shrimp shell [143], litchi shells [144], olive stones [145], cotton [146], silk cocoon [147], bamboo [148], wheat straw [149], mango stone [150], pomelo peels [151], banana peels [152], gelatin [153], cassava [154], bark of plane trees [155], starch [156], have been widely explored to prepare hierarchical porous carbons by well-deigned carbonization processes. All of these biomass-derived hierarchical carbons can be used as conductive host of sulfur for lithium-sulfur battery with improved electrochemical performances.…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

“…It is well‐known that natural processes and anthropogenic influence can change the quality of natural water resources, limiting the potential for water use for human consumption as well as industrial and agricultural purposes . The contamination of drinking water with metals, due to their potential acute (occurring in the short term) and/or chronic (occurring over the long term) adverse effects on human health, can lead to life‐threatening cancers and neurological disorders . Negative health effects make the metal pollution of natural water resources an ongoing global environmental issue.…”

Assessment of Khibiny Alkaline Massif groundwater quality using statistical methods and water quality index

Groundwater is a major source for the water supply of households in the mining‐intensive area of Khibiny Alkaline Massif, Kola Peninsula, in the Arctic. There are an increasing number of signs of groundwater quality deterioration in the area caused by the presence of elevated aluminum concentrations. Groundwater quality studies using univariate and multivariate statistical methods and the Water Quality Index were conducted to analyze a field dataset including 12 groundwater quality parameters monitored between 1999 and 2012. Descriptive statistics showed that the monitored water did not meet the established drinking water standards for aluminum concentration and pH level. The calculated Spearman correlation coefficient matrix revealed statistically significant associations (α‐level = .05) between Al concentrations and pH values, concentrations of SO42−, NO3−, Cl−, and TDS. Factor analysis using the principal component analysis extraction method (FA/PCA) identified four major influencing factors. Altogether the factors captured 67.53% of the dataset total variance. The outcomes of the hierarchical cluster analysis (HCA) revealed that the 12 monitored groundwater quality parameters can be grouped into three clusters where the concentration of Al and pH level formed a separate cluster. The calculated score values of the Canadian Council of Ministers of the Environment Water Quality Index indicated a deterioration of groundwater quality over the monitoring period.
