TL;DR: In this paper, the authors describe a new calorimeter for measuring heat capacity in the range 1-35 K, using a silicon chip bolometer as sample holder, temperature sensor, and sample heater.
Abstract: We describe a new calorimeter for measuring heat capacity in the range 1–35 K, using a silicon chip bolometer as sample holder, temperature sensor, and sample heater. The apparatus is capable of measuring very small samples (1–500 mg), and may be used with a number of different experimental methods.

TL;DR: In this article, a low temperature thermometer and bolometer were demonstrated on a simple diffusion and etching procedure on otherwise insulating silicon substrates, where the temperature coefficients of the resistance of these layers of the order of unity can be obtained at any temperatures below 20 K.
Abstract: By simple diffusion and etching procedures low temperature sensitive surface layers can be prepared on otherwise insulating silicon substrates. Temperature coefficients of the resistance of these layers of the order of unity can be obtained at any temperatures below 20 K. The usefulness of this silicon device as a low temperature thermometer and bolometer is demonstrated.

TL;DR: In this paper, the authors examined the performance of a thermal-relaxation calorimeter that operates in the temperature range of 1.8-395 K. The accuracy of the PPMS specific heat data is determined by comparing data measured on copper and synthetic sapphire samples with standard literature values.

TL;DR: The reaction of [MII(OH2)6]-NO3)2 (M = Co, Ni) and [N(CN)2]- leads to formation of isomorphous M[N[CN]2]2 [M =Co (2a), Ni (3)], respectively.
Abstract: The reaction of [MII(OH2)6](NO3)2 (M = Co, Ni) and [N(CN)2]- leads to formation of isomorphous M[N(CN)2]2 [M = Co (2a), Ni (3)], respectively, while the reaction of [CoII(OH2)6](NO3)2 in 1% pyridin...
