“…10,11 The fuel cell technology has been considered as an efficient, clean, and low-cost way to produce electricity for many applications. [12][13][14] The overall ligninto-electricity efficiency by fuel cells has been proven to be much higher than that of electricity generation by combustion. 15,16 One common group of lignin fuel cells, namely indirect lignin fuel cells, can achieve high power density when operated at high temperature.…”

“…These include high cost, the requirement to employ it in large molar excess to pre-catalysts, and the loss of stability during prolonged storage, resulting in loss of activating capabilities and irreproducibility of polymers properties. According to the literature, triisobutylaluminium (TIBA)/borate is an excellent activator of metallocene complexes in the polymerization of olefins [ 25 , 26 , 27 , 28 ].…”

In toluene at 50 °C, the vinyl addition polymerization of 4-vinyl-cyclohexene (VCH) comonomers with ethylene is investigated using symmetrical metallocene (rac-Et(Ind)2ZrCl2) combined with borate/TIBA. To demonstrate the polymerizations’ living character, cyclic VCH with linear-exocyclicπ and endocyclicπ bonds produces monomodal polymers, but the dispersity (Ɖ) was broader. The copolymers obtained can be dissolved in conventional organic solvent and have excellent thermal stability and crystalline temperature (ΔHm), and their melting temperature (Tm) varies from 109 to 126 °C, and ΔHm ranges from 80 to 128 (J/g). Secondly, the distribution of polymeric catalysts engaged in polymer chain synthesis and the nature of the dormant state are two of the most essential yet fundamentally unknown aspects. Comprehensive and exhaustive kinetics of E/VCH have shown numerous different kinetic aspects that are interpreted as manifestations of polymeric catalysts or of the instability of several types of active center [Zr]/[C*] fluctuations and formation rates of chain propagation RpE, RpVCH, and propagation rate constants kpE and kpVCH, the quantitative relationship between RpE, RpVCH and kpE, kpVCH and catalyst structures, their constituent polymer Mw, and their reactivity response to the endocyclic and exocyclic bonds of VCH. The kinetic parameters RpE, RpVCH, kpE, and kpVCH, which are the apparent rates for the metallocene-catalyzed E/VCH, RpE, and kpE values, are much more significant than RpVCH and kpVCH at 120 s, RpE and RpVCH 39.63 and 0.78, and the kpE and kpVCH values are 6461 and 93 L/mol·s, respectively, and minor diffusion barriers are recommended in the early stages. Compared with previously reported PE, RpE and kpE values are 34.2 and 7080 L/mol·s. VCH increases the RpE in the initial stage, as we are expecting; this means that the exocyclic bond of VCH is more active at the initial level, and that the chain transfer reaction of cyclic internal π double is increased with the reaction time. The tp versus Rp, kp, and [Zr]/[C*] fraction count may be fitted to a model that invokes deactivation of growing polymer chains. At tp 120–360 s higher, the incorporation rate of VCH suppresses E insertion, resulting in reduced molecular weight.

“…Therefore, there is a need to develop and adopt sustainable technologies that can treat wastewater and recover resources simultaneously. Microbial fuel cells (MFCs) are novel and sustainable systems that electrochemically convert chemical energy, present between chemical bonds of organic compounds, into electrical energy (Ren et al 2014;Moradian et al 2021).…”

Microbial fuel cells (MFCs) are devices that exploit the electrochemically active microorganisms for the oxidative conversion of organic compounds into electricity. MFC technology is therefore expected to be a viable solution for domestic and industrial wastewater treatment as an alternative to the currently applied activated-sludge process. Despite its potential, the technology is facing application challenges because of high cost, low stability, and limited understanding of cell design and operation. In this experimental study, a double-chambered MFC with graphite electrodes and a proton-conducting membrane is used in a batch mode to study the potential of resource recovery from dairy effluent and identify the process limitations. Results showed a promising cell performance as the chemical oxygen demand of the wastewater reduced from 4520 mg/l to 850 mg/l in 10 days including the time required for biofilm development. The highest open-circuit voltage of 396 mV was recorded on the third day along with the highest power density of 36.39 mW/m 2 corresponding to a current density of 0.30 A/m 2 . Further, the electrochemical impedance spectroscopy revealed that the activation polarization of aerated cathode is the main contributor to cell internal resistance followed by the ohmic resistance.
