Ni-rich positive electrodes for Li-ion batteries can provide enhanced initial discharge capacity yet suffer from significant degradation upon cycling. Fluorination of NMC811 results in a retention more than 90% after 100 cycles cycling to 4.4 VLi. The increased stability F-modified be attributed the modification oxide electronic structures, where density functional theory calculations shows tha...

The research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. These materials are promising for optoelectronic device technology such as solar cells. On the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. The Co...

Here, capacitive deionization technology (CDI) using modified activated carbon fiber felt (ACF) electrodes was proposed to provide a new strategy for the challenge of simultaneous phosphorus and fluoride wastewater treatment. The acid-modified iron-loaded ACF (A@Fe-ACF) obtained by modifying through two-step impregnation method. After modification, oxygen-containing functional groups on increas...

Abstract In this work, a non-fluorinated surface treatment, i.e., hydrophobized silicone nanofilaments, was applied on both birch and acetylated wood samples via gas-phase based reaction. A superhydrophobic behavior observed the surface-modified as revealed by static water contact angles (CAs) greater than 160°, also valid for prepared with shortest reaction time of 1 h. The dynamic wettability...

Electric double layer capacitors are energy storage devices with advantages of fast charge-discharge and long life span. Surface modification activated carbon electrodes is an effective way to improve their performance. For this purpose, deoxofluorination sulfur tetrafluoride was attempted in study. Successful introduction fluorine atom on the surface resulted increased capacitance improved cou...
