Biotemplating fabrication, mechanical and electrical characterizations of NbC nanowire arrays from the bamboo substrate

Catalyst‐free in situ synthesis of ZrC nanowires with excellent thermal stability

“…After heat treatment at 2450°C, the ZrCNWs break into short whiskers with the diameter of 425‐625 nm and the whiskers have stepped surface morphology, as displayed in Figure 8G, h and i. It can be concluded that the increase of heat treatment temperature leads to the aspect ratio decrease and coarseness of ZrCNWs, which are attributed to the high surface energy of ZrCNWs and the stacking faults inside the nanowires 32 . Subsequently, the internal lattice changes of ZrCNWs after heat treated at different temperatures were investigated to further explain the reason for the differences in morphology evolution.…”

The Mechanical Properties of Nanowires

“…The AFM‐based three‐point bending test has been used for characterizing the elastic modulus of various NWs, including Si, Ge, BN,LaB 6 , TiSi 2 , NiC, SiC, Na 4 Mn 9 O 18 , SiO 2 , SrB 2 O 4 , Co 3 O 4 /CoO, ZnO, and metallic glasses . A sharp AFM tip may cause damage to the NW being tested, as shown in Figure b.…”

Large-scale synthesis of TiC whiskers by carbothermal reduction with microcrystalline cellulose as the carbon source

“…Cellulose undergoes different reactions to form several gases (CO, C x H y , etc.) and solid (chars) under heating [14][15][16]21]. Both gases and the solid chars can serve as the carbon source during the reaction.…”

“…So high yield but with low quality or high quality with low yield of whisker greatly limited the wide application of this economical method. Until very recently, several works have attracted people's attention on other carbon sources, such as T-shirt [14] or bamboo [15,16], phenolic resol [17] and sucrose [18]. Compared with carbon black, all of the new carbon sources will be decomposed during heating, which can surely lead to a low packing density after sintering.…”
