Glucoamylases (GLL) hydrolyze starch to glucose syrup without yielding intermediate oligosaccharides, but their lack of stability under industrial conditions poses a major limiting factor. Using consensus- and ancestral-based machine-learning tools, functional GLL with six mutations (GLLI73l/T130V/N212V/D238G/N327M/S332P) was constructed that exhibited superior hydrolytic activity relative the wild-type (WT-GLL). An oxidized multi-walled carbon nanotube (oMW-CNT) used as solid support...
To date, optimizing electrolytes has become a promising approach to enable high-voltage, high-performance lithium-ion cells. Herein, study is performed evaluate the potential of difluoroethylene carbonate (DFEC) replace fluoroethylene (FEC) and deliver comparable or even superior performance at high voltage. It unveiled that moderately increasing lithium salt inside DFEC-based electrolyte enhances high-voltage cells, with outperforming FEC-based counterpart. Moreover, also fits LiFePO4...
In this study, the mild steel corrosion inhibition performance and corresponding mechanisms of five imidazolium-based ionic liquids (ILs) in hydrogen sulfide (H2S) hydrochloric acid (HCl) solutions were investigated using electrochemical experiments, weight loss measurement, morphology analysis, quantum chemical calculation. The results revealed that these ILs inhibited H2S HCl did not change mechanism reaction. ability decreased when temperature increased. 1-Allyl-3-methylimidazolium...
Nowadays, the extended usage of lithium/sodium ion batteries (LIBs/SIBs) encounters nerve-wracking issues, including a lack suitable reservoirs and high thermal runaway hazards. Although using TiO2 Li4Ti5O12 has been confirmed to be effective in improving battery safety, their low theoretical capacities inevitably cause damage electrochemical performance battery. Achieving win-win results become an urgent necessity. This study designed metal-organic framework (MOF)-derived situ carbon-coated...
The current work performs a comprehensive investigation to determine the best blend between fluoroethylene carbonate and common solvents, that is, ethyl methyl (EMC), diethyl (DEC), dimethyl (DMC), for high-voltage high-safety lithium-ion cells. These three kinds of electrolytes denoted FEMC, FDEC, FDMC, respectively, are researched herein. cells containing FDMC exhibit more superior performance in long-term cycling high-temperature storage at high voltages. This may be ascribed thin but...
In this study, a nonflammable all-fluorinated electrolyte for lithium-ion cells with Li(Ni
Abstract Four imidazolium‐based ionic liquids (ILs) were selected to investigate the inhibiting effect of ILs with various alkyl chain lengths on corrosion mild steel in H 2 S and HCl solution using electrochemical experiments, weight loss surface analyses, quantum chemical study. The results demonstrated that these acted as mixed‐type inhibitors efficiently inhibited solution. Their excellent inhibition ability was due their adsorption process metal surface, which followed Langmuir...
The corrosive environment in sulfur-containing equipment is often complicated and changeable. This study adopted the Taguchi method to optimize immersion test, L27(313) orthogonal table was used design an corrosion experiment. influence of four factors, namely, total acid number (TAN), sulfur, chlorine, water, on AISI 1020 oil phase studied. It showed that effect chlorine most pronounced sulfur second followed by TAN H2O. also found H2O exceeds after 336 h; meanwhile, interaction between...
This experimental study focuses on the corrosion behavior of aluminum alloys in hydrogen sulfide (H2S) gas and liquid phases. The behaviors 3A21, 6061, 6063 are investigated via scanning electron microscopy, energy dispersive spectroscopy, thermogravimetry-differential calorimetry. results show that rates three types increase with temperature, slope rate curve decreases gradually after reaching a certain temperature. At 75 °C, reached 0.0675 mm/a, 0.0881 mm/a 0.0613 phase, respectively....
