Frontiers in Energy 2019, Volume 13, Issue 4,   Pages 798-807 doi: 10.1007/s11708-019-0633-z

Abstract: and phasing out backward production) plays a more important role.out backward production is the leading factor for the decline in the NCCR in the past decade, followedSince the effect of phasing out backward production may remain at a certain degree given a continualaction of phasing out backward capacity, it is suggested that the organized action of phasing out backwardproduction should be insisted on.

Zooming in and out of ferroptosis in human disease

Frontiers of Medicine 2023, Volume 17, Issue 2,   Pages 173-206 doi: 10.1007/s11684-023-0992-z

Abstract: Ferroptosis is defined as an iron-dependent regulated form of cell death driven by lipid peroxidation. In the past decade, it has been implicated in the pathogenesis of various diseases that together involve almost every organ of the body, including various cancers, neurodegenerative diseases, cardiovascular diseases, lung diseases, liver diseases, kidney diseases, endocrine metabolic diseases, iron-overload-related diseases, orthopedic diseases and autoimmune diseases. Understanding the underlying molecular mechanisms of ferroptosis and its regulatory pathways could provide additional strategies for the management of these disease conditions. Indeed, there are an expanding number of studies suggesting that ferroptosis serves as a bona-fide target for the prevention and treatment of these diseases in relevant pre-clinical models. In this review, we summarize the progress in the research into ferroptosis and its regulatory mechanisms in human disease, while providing evidence in support of ferroptosis as a target for the treatment of these diseases. We also discuss our perspectives on the future directions in the targeting of ferroptosis in human disease.

The German Energiewende and its roll-out of renewable energies: An economic perspective

Sebastian KREUZ, Felix MÜSGENS

Frontiers in Energy 2017, Volume 11, Issue 2,   Pages 126-134 doi: 10.1007/s11708-017-0467-5

Abstract: This paper gives a short overview of the German Energiewende, i.e. the transition of a large and mostly thermal electricity system towards electricity generation from renewable energy source. It discusses both, the motivation of the transitions as future goals and current status. Furthermore, it gives an in-depth view into the changes in economic costs for society as well as electricity price effects, especially for average private households and industrial consumers. It also discusses the benefits of the promotion of renewable energies in Germany.

Washing out heavy metals from contaminated soils from an iron and steel smelting site

Guangxu ZHU,Qingjun GUO,Junxing YANG,Hanzhi ZHANG,Rongfei WEI,Chunyu WANG,Marc PETERS,Xiaoyong ZHOU,Jun YANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 4,   Pages 634-641 doi: 10.1007/s11783-014-0713-6

Abstract: Washing is a promising method for separating contaminants bound to the particles of soil by chemical mobilization. Laboratory batch washing experiments were conducted using deionized water and varying concentrations of oxalic acid, citric acid, tartaric acid, acetic acid, hydrochloric acid and ethylenediaminetetra acetic acid (EDTA) to assess the efficiency of using these chemicals as washing agents and to clean up heavy metals from two heavily polluted soils from an iron and streel smelting site. The toxicity reduction index and remediation costs were analyzed, and the results showed that the soils were polluted with Cd, Pb and Zn. Hydrochloric acid and EDTA were more efficient than the other washing agents in the remediation of the test soils. The maximum total toxicity reduction index showed that 0.5 mol·L hydrochloric acid could achieve the remediation with the lowest costs.
