Evaluation of different functionalized multi-walled carbon nanotubes (MWCNTs) modified asphalts

Archives of Civil Engineering
To improve the aging resistance and prolong the service life of asphalt pavement, this study utilized modified multi-walled carbon nanotubes (MWCNTs) functionalized with carboxyl (MWCNTs-COOH), hydroxyl (MWCNTs-OH), and amino (MWCNTs-NH2) groups. These nanotubes were incorporated into SBS-modified asphalt at a concentration of 1%.

Optimization of Triton X-100 removal and ultrasound probe parameters in the preparation of multiwalled carbon nanotube buckypaper

Materials & Design, 2019
A highly porous film composed of a three-dimensional network of multi-walled carbon nanotube (MWCNT), also known as buckypaper (BP), was prepared by vacuum filtration of a well-dispersed suspension of MWCNT/H20 with the aid Triton X-100 surfactant.

Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes

Advanced Energy Materials, EarlyView.
The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...

Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, EarlyView.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.
