Development of multiatom-doped carbon nanomaterials as effective electrocatalysts or supports for fuel cell reactions is of great significance due to their outstanding performance. However, the construction of the carbon nanomaterials with multiatom doping and the mechanism of interaction among doped elements remain grand challenging. Herein, we de...

The phytochemical profiles and antioxidant capacities of 14 cowpea varieties (7 improved and 7 landraces) grown in Ethiopia were studied. The total phenolic, flavonoids, and monomeric anthocyanin contents (mg/100 g flour dry matter basis, db) ranged from 1210 to 1610 gallic acid equivalents, 250 to 1110 catechin equivalents and 3 to 7 cyanidin-3-gl...
Implementing the hierarchical structures of non-noble-metal-based electrocatalysts and modulating their composition can help accelerate surface reactions and fulfill the promise of renewable energy devices via water splitting. Herein, molybdenum-based compounds are constructed on activated nickel foam (act-NF) by a one-step hydrothermal growth. The...

We synthesized ordered mesoporous Fe/N/C with highly active Fe-N-X/C sitesdenoted as m-FePhen-C as a non precious metal catalyst (NPMC) for the oxygen reduction reaction in fuel cells. This was the first study that incorporated a catalyst precursor with Fe-N coordination directly in a simple block co-polymer-assisted soft template method for the sy...
As the important structural component of corn stover, hemicellulose could be converted into a variety of high value-added products. However, high quality hemicellulose extraction is not an easy issue. The present study aims to investigate the effects of non-structural components (NSCs) and lignin removal on alkaline extraction of hemicellulose. Alt...
The present study explored the electrochemical behavior of UNS S32750, a super duplex stainless steel which was not commonly researched in previous studies. The effect of bicarbonate (HCO3-) and sulfate (SO42-) on the electrochemical behavior of UNS S32750 duplex stainless steel in the chloride (Cl-) solution was investigated using potentiodynamic...
The Matongo carbonatite intrusion belongs to the Neoproterozoic Upper Ruvubu alkaline plutonic complex (URAPC), that is located in Burundi along the western branch of the East African Rift. Beside the Matongo carbonatite, the URAPC alkaline complex comprises feldspathoidal syenites, diorites, quartz-bearing syenites and granites. Three main facies ...
