Hierarchically porous wood aerogel/polypyrrole(PPy) composite thick electrode for supercapacitor

Boron nitride-mediated semiconductor nanonetwork for an ultralow-power fibrous synaptic transistor and C-reactive protein sensing

“…Two prominent strong peaks of PPy were observed at 1305 cm À1 and 1530 cm À1 , which were assigned to the stretching of the PPy ring and the CQC backbone, respectively. 34 The broad diffraction peak (2y = 261) in the XRD pattern revealed the existence of PPy. All these characteristic peaks proved the successful polymerization of the PPy semiconductor on the fiber substrate.…”

Recent application progress and key challenges of biomass-derived carbons in resistive strain/pressure sensor

“…Besides, the selective removal of lignin could convert the wood into an elastic aerogel with porous structure, which creates the prerequisite for the preparation of pressure sensors (Fig. 9) [119,120]. For example, Hu's group [121] removed the lignin from wood with the help of sodium sulfite and sodium hydroxide and obtained wood aerogels.…”

A perspective on graphene based aerogels and their environmental applications

“…(3) drying of the wet gel, (4) carbonizing of the dried gel and further activation [28]. As previously mentioned, also in this case, by varying the synthesis condition it is possible to regulate and control the average pore diameter and the particle size in the range of several micrometers, making the CAs suitable for thermal insulation applications, especially at high temperatures [44], and for catalysis and electrodes in supercapacitors [46]. They have been involved in many other fields of application, such as biosensors [47,48], hydrogen storage [49], and adsorption.…”
