Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Infrared Quantum Detectors

2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO), 2020
Quantum detectors respond to electromagnetic radiation by generating a photocurrent. The detection mechanism involves absorption of photons whose energy exceeds the band gap of the detector material. The absorption generates excited mobile charge carriers (electron-hole pairs) that form the photocurrent. The quantum detectors sensitive in near infrared

Infrared Detectors

Analytical Chemistry, 1969
Infrared radiation has been studied with detectors of one kind or another since about 1800. The difference between the techniques of the first century-and-a-half and the period since World War II is that the earlier devices were thermal detectors, responding to temperature change caused by integrated absorption of energy, while the more recent devices ...
