Publikováno v: Materials & Design, Vol 191, Iss , Pp - (2020)

A three-dimensional (3D) sintering method of bulk magnetron targets has been developed recently. However, the use of bulk target had the following limitations: constrained geometry, limited chemical-phase composition, small size and cost-effectivenes

Detecting volcanic sulfur dioxide plumes in the Northern Hemisphere using the Brewer spectrophotometers, other networks, and satellite observations

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Iss 1, Pp 551-574 (2017)

This study examines the adequacy of the existing Brewer network to supplement other networks from the ground and space to detect SO2 plumes of volcanic origin. It was found that large volcanic eruptions of the last decade in the Northern Hemisphere h

Effects of urban agglomeration on surface-UV doses: a comparison of Brewer measurements in Warsaw and Belsk, Poland, for the period 2013–2015

Autor: A. E. Czerwińska, J. W. Krzyścin, J. Jarosławski, M. Posyniak

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 13641-13651 (2016)

Specific aerosols and cloud properties over large urban regions seem to generate an island, similar to the well-known urban heat island, leading to lower ultraviolet (UV) radiation intensity compared to the surrounding less polluted areas, thus cr

Autor: J. W. Kaminski, L. Neary, J. Struzewska, J. C. McConnell, A. Lupu, J. Jarosz, K. Toyota, S. L. Gong, J. Côté, X. Liu, K. Chance, A. Richter

Publikováno v: Atmospheric Chemistry and Physics, Vol 8, Iss 12, Pp 3255-3281 (2008)

Tropospheric chemistry and air quality processes were implemented on-line in the Global Environmental Multiscale weather prediction model. The integrated model, GEM-AQ, was developed as a platform to investigate chemical weather at scales from global

Comparative analysis of microstructure, mechanical, and corrosion properties of biodegradable Mg-3Y alloy prepared by selective laser melting and spark plasma sintering

Autor: P. Minárik, M. Zemková, S. Šašek, J. Dittrich, M. Knapek, F. Lukáč, D. Koutný, J. Jaroš, R. Král

Publikováno v: Journal of Magnesium and Alloys, Vol 12, Iss 4, Pp 1496-1510 (2024)

This work explored possibilities of biodegradable magnesium alloy Mg-3Y preparation by two modern powder metallurgy techniques – spark plasma sintering (SPS) and selective laser melting (SLM). The powder material was consolidated by both methods ut
