“…However, E‐PAN high‐strength characteristic peaks are found at 98 Å, 78 Å and 53 Å, which are related to the existence of mesopores in E‐PAN. [ 32 ] It was confirmed that the nano‐skeletal structure with porous surface was obtained by electrospinning of PAN fiber. Therefore, the component diffusion barrier caused by the lack of bonding sites on the adhesive surface of asphalt macromolecules can be effectively solved in the designed nano‐porous fiber skeletal structure.…”

Electrospinning is used to control the interface structure of macro‐polyacrylonitrile (PAN) fibers, and nano‐porous fibers (E‐PAN) which possess enhanced adhesion and interface effects. Herein, E‐PAN was prepared via electrospinning and was in turn incorporated into styrene‐butadiene‐styrene (SBS) asphalt to prepare PAN modified asphalt. The effect of E‐PAN addition on the performance of modified asphalt was explored. Fourier transform infrared (FT‐IR) spectroscopy, X‐ray diffraction, scanning electron microscopy, atomic force microscopy (AFM), and AFM tests confirmed that E‐PAN exhibited a highly rough nano‐porous skeleton without any prominent structural damage during the preparation process. The three major indexes, dynamic shearing rheometer, MSCR, rotational viscosity, and thermogravimetric analysis tests results showed that E‐PAN modified asphalt exhibited excellent viscoelasticity, anti‐rutting and anti‐fatigue properties and thermal stability (THRI of 192.7°C). FT‐IR test of the four components of modified asphalt confirmed that E‐PAN chemically crosslinked with the saturates and aromatics in the base asphalt and SBS, which resulted in a uniform and well‐developed network structure. In addition, Brauner‐Emmett‐Teller and fluorescence microscopy results confirmed that E‐PAN got fully swollen in a behavior similar to that of SBS in the base asphalt, and hence helped SBS to form an excellent network structure in asphalt. E‐PAN played the important role of stress buffer, mutual entanglement, and good thermal insulation inside the asphalt.

Recent Advances in the Lithium Recovery from Water Resources: From Passive to Electrochemical Methods

et al. 2022

View full text Add to dashboard Cite

The ever-increasing amount of batteries used in today's society has led to an increase in the demand of lithium in the last few decades. While mining resources of this element have been steadily exploited and are rapidly depleting, water resources constitute an interesting reservoir just out of reach of current technologies. Several techniques are being explored and novel materials engineered. While evaporation is very time-consuming and has large footprints, ion sieves and supramolecular systems can be suitably tailored and even integrated into membrane and electrochemical techniques. This review gives a comprehensive overview of the available solutions to recover lithium from water resources both by passive and electrically enhanced techniques. Accordingly, this work aims to provide in a single document a rational comparison of outstanding strategies to remove lithium from aqueous sources. To this end, practical figures of merit of both main groups of techniques are provided. An absence of a common experimental protocol and the resulting variability of data and experimental methods are identified. The need for a shared methodology and a common agreement to report performance metrics are underlined.

“…Adsorption is the most promising strategy for recovering Li from aqueous resources because it is more climate-friendly and more effective in an industrial application . Although there are many studies reported in the literature regarding metal ion extraction based on different functionalized composite materials, − aluminum hydroxides (AlOH), , aluminum oxides (AlO x ), manganese oxides (MnO x ), − and titanium oxides (TiO x ) ,− have been known to be the most selective lithium adsorbents until now. They are classified as inorganic crystalline solids either being studied for direct lithium extraction from brines or employed as cathode materials in lithium-ion batteries.…”

Phosphorylated functional cellulose was cross-linked with epichlorohydrin at different ratios because it is a very hydrophilic substance that instantly swells to form a hydrogel when it comes into contact with water. It was aimed to utilize a continuously packed bed column to recover lithium from water under varying operating conditions such as flow rate and bed height. The characterization results confirmed cross-linking based on morphology, structure, surface area, and thermal stability differences. Lithium recovery was more efficient with a low flow rate, but the dynamic sorption process was independent of bed height. The total capacities at the three flow rates with 1.5 cm bed height were 33.56, 30.15, and 25.54 mg g −1 , and the total saturation times at the three different bed heights with 0.5 mL min −1 flow rate were 659, 1001, and 1007 min, respectively. Only 15.75 mL of 5% H 2 SO 4 solution was required to desorb approximately 100% of Li from the saturated sorbent.
