“…It is verified that Mn oxides-loaded biochar exhibited high sorption efficiency for heavy metals Sun et al 2019a). To combine the advantages of Fe and Mn oxides, ferromanganese binary oxide-biochar composites were fabricated and had excellent adsorption capacities for heavy metals (Gao et al 2019b;Wang et al 2019j).…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…In addition, sepsis-induced liver injury is considered as a strong independent predictor of death in the intensive care unit [ 7 ]. Meanwhile, sepsis-induced kidney injury, especially acute kidney injury, is also an important cause associated with the mortality in sepsis [ 8 ]. Therefore, seeking for effective drugs for reducing sepsis-induced kidney and liver damage is essential to overcome the high mortality of sepsis.…”

Dexpanthenol attenuates inflammatory damage and apoptosis in kidney and liver tissues of septic mice

Sepsis is capable of causing systemic infections resulting in multiple organ damage. Dexpanthenol (DXP) has been reported to protect against kidney and liver injury. Therefore, this paper attempts to explore the role of DXP in sepsis-induced kidney and liver injury. A mice model of sepsis was established using the cecal ligation and puncture (CLP) method. The expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein (MCP)-1 in the serum of mice were measured utilizing enzyme linked immunosorbent assay (ELISA). Additionally, the damage of kidney and liver tissues in CLP-induced mice was determined by their respective commercial kits, western blot, and hematoxylin–eosin (HE) staining kits. The apoptosis of kidney and liver tissues in CLP-induced mice was assessed by means of terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and western blot. It was observed that DXP decreased the expressions of TNF-α, IL-1β, IL-6, and MCP-1 in the serum of CLP-induced mice, attenuated the functional impairment, pathological damage, inflammation, and cell apoptosis of kidney tissue. Meanwhile, DXP decreased the functional impairment of liver in CLP-induced mice, reduced the levels of inflammatory factors and antioxidant enzymes, attenuated liver pathological damage, and decreased cell apoptosis in liver tissues. In conclusion, DXP attenuates inflammatory damage and apoptosis in kidney and liver organs in a sepsis model.

“…Attapulgite (palygorskite), a fibrous clay mineral with lamellar structure, has also attracted much attention because of its abundant hydroxyl groups. Attapulgite–biochar composites have proven effective for the immobilization of As and Cd in river sediments because of enhanced surface complexation (Wang, Gu, et al, 2019), and for the adsorption of oxytetracycline in the aqueous media because of enhanced π‐π EDA interactions and the formation of hydrogen bonds (Wang, Yang, et al, 2019). Struvite (NH 4 MgPO 4 ) is a nutrient‐rich mineral that has been commonly used as a fertilizer.…”

Engineered biochars are promising candidates in a wide range of environmental applications, including soil fertility improvement, contaminant immobilization, wastewater treatment and in situ carbon sequestration. This review provides a systematic classification of these novel biochar composites and identifies the promising future trends in composite research and application. It is proposed that metals, minerals, layered double hydroxides, carbonaceous nanomaterials and microorganisms enhance the performances of biochars via distinct mechanisms. In this review, four novel trends are identified and assessed critically. Firstly, facile synthesis methods, in particular ball milling and co‐pyrolysis, have emerged as popular composite fabrication strategies that are suitable for large‐scale applications. Secondly, biochar modification with green materials, such as natural clay minerals and microorganisms, align well with the on‐going green and sustainable remediation (GSR) movement. Furthermore, new applications in soil health improvement and climate change mitigation support the realization of United Nation's Sustainable Development Goals (SDGs). Finally, the importance of field studies is getting more attention, since evidence of field success is critically needed before large‐scale applications.
