With the urgent need for efficient energy storage devices, significant attention has been directed to researching and developing promising anode materials for metal-ion batteries. Through density functional study, we successfully predicted the electrochemical performance of PS and CS monolayers for the first time, which could be used in alkali metal (Li, Na, and K)-ion batteries. Our study examines the energetic, dynamic, and thermal stabilities of pristine monolayers.

Article Synopsis
  • The study evaluates how well different regression methods estimate the performance of TiO/Cu catalysts for converting CO to methanol, specifically using hydrogen exfoliated graphene (HEG).
  • The research found that 30 wt% HEG provided the best conversion efficiency in producing methanol, with key factors such as HEG dosing and CO inflow rate significantly influencing the results.
  • Nonlinear regression via artificial neural networks (ANN) outperformed linear regression methods, achieving a higher determination coefficient and more accurate predictions in line with experimental data.

The presence of a fluoroquinolone base veterinary antibacterial drug enrofloxacin in aqueous media poses a major threat due to its ecotoxicity on aquatic microbiota. Hence, for the first time, an attempt was made to remove enrofloxacin (ENX) from its aqueous solution by employing micellar-enhanced ultrafiltration (MEUF) where cetylpyridinium bromide (CPB), a cationic surfactant was used for micellization. Response surface methodology (RSM) with central composite design (CCD) approach was applied to design the experiment, and to optimize the process parameters, namely, ENX concentration (3-15 mg/L), transmembrane pressure (2-6 kg/cm), recirculation flow rate (5.

The current investigation deals with how chemically activated carbon derived from industrial paper sludge (ACPS) performs on sorptive removal of enrofloxacin (ENF), an antibacterial drug from its water solution. Thermogravimetric (TGA) and proximate analysis of raw paper sludge (RPS) were conducted. ACPS was characterized with proximate analysis, XRD, FT-IR, SEM and BET.
