The thermally induced volume phase transition process of poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAM-co-AA) hydrogel is studied using FT-IR spectroscopy in combination with the perturbation correlation moving window (PCMW) technique and two-dimensional correlation spectroscopy (2Dcos) analysis. According to PCMW spectra analysis, an elevation of volume phase transition temperature (VPTT...

Hydrogen (H2) will play a key role in the future low-carbon energy society. The industrial production of hydrogen involves chemical reactions and purification steps. Pressure Swing Adsorption (PSA) is versatile process able to produce ultrapure (99.99+%) from various gas mixtures, resulting most widespread technology worldwide. In particular, Polybed PSA system, having more than six beds comple...

Lithium recovery from brine is recently attracting significant attention due to increasing industrial demand for energy storage, such as batteries. The lithium was investigated using hydrogen manganese oxide adsorbent. adsorbent HMn2O4 (HMO) derived the spinel (LMO), which synthesized LiOH and MnO2 precursor through reflux method. characterized Scanning Electron Microscopy identify its physical...
