Nitrogen-doped carbon nanomaterials are known to be excellent electrocatalysts for the oxygen reduction reaction (ORR) in polymer electrolyte fuel cells. In this study, we used a new and simple post-doping synthesis method to prepare nitrogen-doped s

We prepared and characterized multi-walled carbon nanotube (MWCNT) solids by de-fluorination of fluorinated MWCNTs using spark plasma sintering. In order to investigate the influence of the structure of MWCNT on the mechanical strength of the resulti

Zoanthids comprise an order of benthic, generally colonial cnidarians, which can usually be distinguished from other hexacorallians by embedded sand and detritus in their mesoglea to help strengthen their structure. These animals are becoming increas

Binder-free multi-walled carbon nanotube (MWCNT) blocks from fluorinated MWCNTs were prepared using thermal heating and a compression method in vacuo. The resulting carbon nanotube blocks are lighter than graphite, can be machined and polished, posse

Ultrathin poly(vinyl alcohol) (PVA) films were fabricated on a gold substrate by a repetitive process based on physical adsorption from aqueous solution in the presence of NaCl and subsequent drying. A quartz crystal microbalance (QCM) was used to an

We produced large binder-free multi-walled carbon nanotube (MWNT) blocks from fluorinated MWNTs using thermal heating and a compressing method in vacuo. This technique resulted in the formation of covalent MWNT networks generated by the introduction

We have studied the effects of atomic hydrogen (H) irradiation under near-optimal GaN growth conditions. Atomic H irradiation during GaN growth suppresses three-dimensional growth and promotes two-dimensional growth under a slightly nitrogen-rich gro

We have studied the effects of atomic hydrogen(H) generated by a hot tungsten (W) cracking cell upon substrate cleaning and GaN growth by RF-MBE. And we have shown atomic H irradiation during thermal cleaning stage produce a smooth surface, which in
