ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

ABSTRACT Lithium–sulfur batteries have attracted extensive interest owing to their exceptionally high theoretical energy density and environmental benignity. However, their practical performance remains severely constrained by intrinsic challenges, including the polysulfide shuttle effect and large volume expansion during cycling, which markedly ...

通过营养液培养试验研究不同硫镉水平对超积累东南景天抗氧化酶活性的影响。结果表明,在增施镉水平下东南景天叶片的MDA含量随着硫水平增加显著降低,Cd0水平下S2处理显著降低MDA含量达12.4%。相反,东南景天叶片的MDA含量随着镉水平的提高显著增加18.4%~137.7%。镉硫交互对超积累东南景天叶片抗氧化酶活性有显著影响。超积累东南景天叶片SOD活性随着硫、镉水平的增加而增加,以S3>S2>S1,Cd100>Cd10>Cd0。增施硫显著提高Cd10和Cd100水平下东南景天叶片POD活性。在S1 ...

A crise do conhecimento científico indica a necessidade de repensarmos o modelo uniforme de seu discurso na direção da abertura ao diálogo com outras linguagens e instâncias do saber humano, como a filosofia e, principalmente, as artes. Partindo desse pressuposto, faremos uso de alguns trechos do livro gráfico Do Inferno para analisarmos as ...

ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...

为确定土壤铜、硫污染对苹果幼树生长发育的影响,以硫铁矿尾矿砂河滩垫地上栽植的苹果幼树为试材,研究土壤中的不同铜硫含量对苹果幼树生长发育的影响。结果表明:土壤中的铜含量≥46.8mg/kg,土壤有效硫含量≥368.7mg/kg时,苹果幼树的生长发育就会受到抑制;土壤中的铜含量≥53.9mg/kg,土壤有效硫含量≥538.0mg/kg时,苹果幼树受毒害甚至死亡。苹果幼树各器官铜含量的分布规律为:根系>叶片>新梢>1年生枝>2年生枝>主干,硫含量分布规律为:叶片>根系>新梢>1年生枝>2年生枝>主干 ...

ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

ABSTRACT With high theoretical capacity and low cost, bismuth sulfide (Bi2S3) demonstrates considerable potential as an anode for sodium/potassium‐ion batteries (SIBs/PIBs). Unfortunately, significant volume variation, low electrical conductivity, and dissolution of polysulfides drastically weaken their intrinsic merits.
