... Numerous reported have shown that most microorganisms can secrete chromate reductases to reduce highly toxic Cr(VI) to less toxic Cr(III) [15,16]. For extracellular Cr(VI) reduction of microorganisms, extracellular chromate reductases, enzyme-mediated reduction by cell membrane proteins, and chemical reduction mediated by cell surface functional groups are the main ways for microbial extracellular Cr(VI) reduction [17,18]. Pseudomonas aeruginosa can secrete soluble polymers, which are reductive properties can reduce Cr(VI) in the extracellular environment [17]. ...

... Theoretically, uranium can exist in four oxidation states [69], including +3, +4, +5, and +6. However, due to the instability of uranium in the +3 and +5 states, uranium minerals typically manifest in nature in the +4 (U(IV)) and +6 (U(VI)) oxidation states [70][71][72][73]. Specifically, U(IV) typically appears in the solid forms of uraninite (UO 2 ) and coffinite (U(SiO 4 ) 1−x (OH) 4x ) [37,74], representing common and stable uranium configurations. ...

... Carbon-based materials offer fresh prospects for constructing ECHs within polymer matrices. These networks not only create channels for electron transport via the π-conjugated structure but likewise improve the mechanical characteristics of the materials because of their large surface area and numerous surface functionalities [64]. Typically, carbon nanotubes (CNTs) and graphene have been the most extensively employed kinds of carbon materials as conductive fillers for the creation of conductive hydrogels [65]. ...

... Various ways have been used to treat wastewater containing lead ions, including complexation, precipitation, microbiological, membrane technology, and adsorption. [9][10][11][12][13] However, most of those ways have the disadvantages of high cost, poor selectivity, and secondary pollution. Therefore, the adsorption technique has been proverbially used [14]. ...

... Cellulose is an important component in plant fiber with different controllable sizes and could be chemically modified by simple reactions for polyhydroxy structure [10][11][12]. Therefore, micro-nano cellulose has gradually become a research hotspot due to its amphiphilic properties [13][14][15][16], excellent dispersibility [17,18], and high modulus [19]. Equally important, lignin is a natural biological adhesive that has compatibility and synergy with cellulose. ...

... Most hydrogel sensors are created by incorporating conductive materials into the three-dimensional (3D) network of hydrogels [10][11][12]. Attaining a uniform dispersion of conductive fillers within hydrogels is frequently a challenging task. When dispersion is non-uniform, it typically results in suboptimal conductivity and can adversely affect the mechanical properties of the hydrogels [13][14][15][16]. ...
