资料摘要
资料下载Many physiological behaviors such as heartbeat and brainwaves exhibit rhythmical oscillations. Unlike conventional stimuli-responsive materials which act in an equilibrium state,1,2 such a living system works in a nonequilibrium state. No doubt,biomimetic systems with rhythmical action can not only help us to understand nonequilibrium thermodynamics and phenomena in life but find applications in nanodevices, biomaterials and drug delivery. In the past years, self-oscillating polymer gels,3 free polymer chains,4 and immobilized macromolecules5 have been prepared. These materials work in a closed system driven by the Belousov-Zhabotinsky reaction, so the oscillation amplitude decays with time. In parallel, oscillations of some polymer gels6,7 and DNA8 have also been achieved in an open system driven by the Landolt reaction, whose amplitude holds a constant due to the continuous input. Obviously, the latter is more analogous to a physiological system, namely, the oscillation has invariant amplitude under a constant input.

TLS-100
简介：The TLS-100 is a portable thermal conductivity meter used to measure thermal conductivity and thermal resistivity. Perfect for testing the thermal conductivity of soil, polymers, viscous liquids, and other soft materials; as well as testing the thermal conductivity of concrete, rock, stone, or other hard materials. Tests can be performed with the push of a button. The collected data is automatically analyzed and results are displayed immediately.
THW--L2
简介：The Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896. The THW-L2 was designed with speed and operational simplicity in mind. With a single measurement of less than 2 seconds in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. The THW-L2 utilizes a non-stationary measurement approach and rapid test times to limit convective effects for samples with a wide range of viscosities.
HFM brochure
简介：The Heat Flow Meter (HFM) 100 is an easy-to-use rapid technique for the measurement of thermal resistance and thermal conductivity of insulation products, construction materials, packaging, and assemblies. Thermal conductivity is a measure of the ability of a material to conduct heat and can be critical for defining energy efficiency and thermal performance in materials. The Thermtest HFM has been designed and engineered to combine the highest accuracy, repeatability, widest temperature range, and industry leading performance, all at an exceptional value.
