Here, a high sensitivity gas sensing ink based on sulfonated rGO (S-rGO) decorated with
SnS2 is synthesized for room temperature NO2 and NH3 detection. This sensing ink …

The escalating development and improvement of gas sensing ability in industrial equipment,
or “machine olfactory”, propels the evolution of gas sensors toward enhanced sensitivity …

The term graphene was coined using the prefix “graph” taken from graphite and the suffix “-
ene” for the C= C bond, by Boehm et al. in 1986. The synthesis of graphene can be done …

We have reported a facile approach to fabricate poly (3-hexylthiophene)/reduced graphene
oxide (P3HT/rGO) composite films via the photoirradiation of the corresponding composite …

Achieving convenient and accurate detection of indoor ppb-level formaldehyde is an urgent
requirement to ensure a healthy working and living environment for people. Herein …

Formaldehyde (HCHO) sensing plays a critical role for indoor environment monitoring in
smart home systems. Inspired by the unique hierarchical structure of cactus, we have …
