TL;DR: Graphene, a monolayer of graphite sheet consisting of sp2 hybridized carbon atoms covalently bonded to three other atoms (discovered in 2004), has recently attracted the attention of chemical sensor researchers owing to its unprecedented structural, mechanical and electrical properties.

TL;DR: In this paper, a hybrid 1-bit full adder design employing both complementary metal-oxide-semiconductor (CMOS) logic and transmission gate logic is reported and is found to offer significant improvement in terms of power and speed.

TL;DR: In this paper, an undoped nanocrystalline n-ZnO thin films were deposited on SiO 2 -coated p-Si substrates by sol-gel technique to fabricate ZnO-based resistive sensors for methane detection.

TL;DR: In this article, the technological developments related to the various designs and geometries of microheaters and their fabrication technology employing different suitable heating materials, for closed and suspended-type silicon membranes have been discussed critically with particular emphasis on the relative merits and demerits with reference to heater parameters such as power consumption, temperature distribution, response time, and mechanical stability/reliability.

TL;DR: This type of sensor was found to give fairly appreciable response for lower methane concentrations and for higher methane concentrations, and response is detectable even at 100 °C where the power consumption is only ∼40 mW.
