Atmosphere, 2020 The Antarctic Peninsula (AP) region has been one of the regions on Earth with strongest warming since 1950. However, the northwest of the AP showed a cooling from 2000 to 2015, which had local consequences with an increase in snow accumulation and a ...

Fluid transport in a thick layer above an active ciliated surface
Biophysical Journal, 1980 The discrete cilia approach is employed to describe the flow field above an active ciliated surface in a layer of finite depth. The infinite-size cilia surface model predicts a uniform flow above the cilia surface. Modifications as a result of a finitely extending cilia surface inside a finite-size dish predict a backward parabolic profile above an ...

Energies, 2022 The radioactive gas radon is ubiquitous in the environment and is a major contributor to the human inhalation dose. It is the second leading cause of lung cancer after smoking. Radon concentrations are particularly high in the air of radon-hazardous facilities—uranium mines and radioactive waste repositories containing radium.

Optically Active Spin Defects in Few-Layer Thick Hexagonal Boron Nitride
Physical Review Letters, 2023 Optically-active spin defects in hexagonal boron nitride (hBN) are promising quantum systems for the design of two-dimensional quantum sensing units offering optimal proximity to the sample being probed. In this work, we first demonstrate that the electron spin resonance frequencies of boron vacancy centres (V$_\text{B}^-$) can be detected optically in

Active-layer thickness estimation from X-band SAR backscatter intensity [PDF]
The Cryosphere, 2017 The active layer above the permafrost, which seasonally thaws during summer, is an important parameter for monitoring the state of permafrost. Its thickness is typically measured locally, but a range of methods which utilize information from satellite ...

Temporal and spatial variation in active layer depth in the McMurdo Sound Region, Antarctica [PDF]
, 2010 A soil climate monitoring network, consisting of seven automated weather stations, was established between 1999 and 2003, ranging from Minna Bluff to Granite Harbour and from near sea level to about 1700m on the edge of the polar plateau.

Effect of PbS Film Thickness on the Performance of Colloidal Quantum Dot Solar Cells [PDF]
Journal of Nanostructures, 2013 Colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. In this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (PbS) nanocrystals (active layer) to the

Hall generator with variable active-layer thickness
Electronics Letters, 1967 The principle of operation of a new semiconductor device, a Hall generator with a variable-thickness active layer, is discussed. Such a device results from the location of a p-n junction in close proximity to the surface of a semiconductor plate, thus isolating the thin active layer of the Hall generator from the base. Two additional electrodes, one on
