Sub-terahertz feedback interferometry and imaging with emitters in 130 nm BiCMOS technology

Scientific Reports, 2023
In this work, we present the effect of self-mixing in compact terahertz emitters implemented in a 130 nm SiGe BiCMOS technology. The devices are based on a differential Colpitts oscillator topology with optimized emission frequency at the fundamental ...

The near-room-temperature upsurge of electrical resistivity in Lu-H-N is not superconductivity, but a metal-to-poor-conductor transition

Matter and Radiation at Extremes, 2023
The recent report of superconductivity in nitrogen-doped lutetium hydride (Lu-H-N) at 294 K and 1 GPa brought hope for long-sought-after ambient-condition superconductors.

Some Magnetic Properties and Magnetocaloric Effects in the High-Temperature Antiferromagnet YbCoC₂

Magnetochemistry, 2023
The YbCoC2 compound, which crystallizes in a base-centered orthorhombic unit cell in the Amm2 space group CeNiC2 structure, is unique among Yb-based compounds due to the highest magnetic ordering temperature of TN=27 K.

Radiation Pressure Quantization [PDF]

, 2018
Kepler's observation of comets tails initiated the research on the radiation pressure of celestial objects and 250 years later they found new incarnation after the Maxwell's equations were formulated to describe a plethora of light-matter coupling ...

Mechanical compression to characterize the robustness of liquid marbles [PDF]

, 2015
In this work, we have devised a new approach to measure the critical pressure that a liquid marble can withstand. A liquid marble is gradually squeezed under a mechanical compression applied by two parallel plates.

The application of low pressure storage to maintain the quality of zucchinis [PDF]

, 2017
Zucchini (Cucurbita pepo var. cylindrica) were stored at low pressure (4 kPa) at 10°C at 100% relative humidity for 11 days. Fruit quality was examined upon removal and after being transferred to normal atmosphere (101 kPa) at 20°C for three days ...
