The C1 NQR frequencies in MgTeCl6 • 6 H 2 0 , NiTeCl6 • 6 H 2 0 , and NiIrCl6 • 6 H 2 0 have been determined at various temperatures. These compounds form rhombohedral crystals with the space group R3, showing a single resonance line. The C1 NQR frequencies of the Te(IV) complexes exhibit an unusual positive temperature coefficient. The deuterated analogs of the Te(IV) complexes show a small fr...

We have developed a flexible thermoelectric nanogenerator (TENG) that is based on a Te-nanowire/poly(3-hexyl thiophene) (P3HT) polymer composite as the thermoelectric material with a positive Seebeck coefficient of 285 μV/K. A linear relationship between the output voltage of TENG and the temperature difference across the device was observed. Under a temperature difference of 55 K, two TENGs ca...

The ice edge of the Barents Sea east of Svalbard is an area where the warm, salty water of the North Atlantic (AtW) interacts with cold, less dense, saline Arctic water (ArW) and the water produced by melting ice (MIW). Many of the CTD profiles (CTD stands for Conductivity-Temperature-Depth) obtained in this region by Norwegian Polar Institute expeditions in 1999 and 2007 contain layers that ar...

Plant δ13C-temperature (δ-T) relation has been established in many systems and is often used as paleotemperature transfer function. However, it is still unclear about the exact contributions of temperature variation to plant 13C discrimination because of covariation between temperature and precipitation (aridity), which reduces confidence in reconstruction of paleoclimate. In this study, we mea...

This paper deals with a single-crystal-silicon (SCS) MEMS resonator with improved temperature stability. While simulations have shown that the temperature coefficient of resonant frequency can be down to 1 ppm/°C, preliminary measurements on non-optimised structures gave evidence of a temperature coefficient of 29 ppm/°C. Design, optimisation, experimental results with post process simulation a...

This paper presents results concerning climatic conditions affecting diameter growth of Sitka spruce introduced to Baltic Pomerania (Sławno Forest District). A relatively high homogeneity of tree-ring series permitted to construct on their basis the tree-ring chronology of Sitka spruce. A significant positive correlation was found between radial increments of Sitka spruce and air temperatures o...

introduction the dynamic state index (dsi) is being introduced on the basis of a newly developed theory termed the energy-vorticity theory (evt). as a weather index, the dsi can describe the temporal sequence and intensity of areas of high and low pressure; but as a climate index, it can also diagnose climate change based on the variation in solar radiation or the influences of friction. in phy...

Application of capillary electrophoresis (CE) to temperature-sensitive biomolecular interactions requires knowledge of the temperature inside the capillary. The simplest approach to finding temperature in CE employs a molecular probe with a temperature-dependent parameter. Up until now only spectral parameters of molecular probes were utilized for temperature measurements in CE. The arbitrary n...

in this study, we aimed to reconstruct the mean, maximum mean and ‎minimum mean temperature from the chronology of tree rings width of two ‎quercus persica sites in dena region, where efficient climatic data have a ‎short period (1982-2011). the duration of common chronology of the sites ‎is 131 years (1881-2011).considering the strong correlation between ‎climatic data and growth rin...
