Multifunctional lignin-based nanocomposites and nanohybrids

“…During the recent years, there have been many reviews on lignin nanoparticles and their applications, 9,[20][21][22][23][24][25][26][27][28]29 chemical and microbial transformation of lignin to chemicals and polymer precursors, 30,31 and chemical functionalization and processing of lignin into various materials (not in the nanoscale). 2,[32][33][34][35][36][37][38][39][40] Though many of the prior reviews discuss formulation of lignin-based polymers and composite systems, [41][42][43][44][45][46][47][48][49] the literature is lacking a review on nanocomposites and hybrid materials based on lignin. These two classes of materials are quickly gaining momentum.…”

Redox-induced electricity for energy scavenging and self-powered sensors

“…Considering its versatile scope and simple mechanisms, the applicability of redox-based energy scavenging technology is rapidly gaining importance in the scientic community. Most importantly, the fabricated self-powered energy harvesting sensor devices can be exibly used both for human health technologies 32,33 and environment monitoring systems 34 without any external energy sources that may include many toxic and harmful elements to humans and the environment. Additionally, multitasking facilities can be embellished on the fabricated devices easily without any complex modication that can reduce the output performances.…”

Poly(3,4‐ethylenedioxythiophene) in Dye‐Sensitized Solar Cells: Toward Solid‐State and Platinum‐Free Photovoltaics

“…The goal is to increase the safety and ease of production of DSSCs (by replacing a liquid electrolyte based on organic solvents with a solid conduction system), [56][57][58][59][60] as well as to reduce the cost of the raw materials used for cells fabrication (by replacing platinum with less expensive alternative and carrying out accurate life cycle assessment-LCA-analysis). [61][62][63][64][65] The scientific community has proposed numerous solutions to these purposes, which are summarized in various reviews present in the literature. [66][67][68][69][70] In this sector, poly(3,4-ethylenedioxythiophene) (PEDOT) plays an important role.…”
