Unlike graphite, hBN is:electrically insulating chemically inert resistant to wetting by most molten metals stable in nitrogen and inert atmospheres up to very high temperatures These traits give BN crucibles capabilities that alumina, quartz, and even graphite cannot match, especially in environments where purity and non-contamination matter.2. ...
Did you know that you can now use Zygo Optical Profilers within argon chambers? This groundbreaking capability allows for precise metrology in controlled argon environments, commonly referred to as Argon Gloveboxes. This unique and thoroughly tested feature enables optical profiling under argon conditions, opening new possibilities for research and manufacturing ...
ALICEnet is a network of measuring stations operated by Italian research institutions and environmental authorities to improve the multidisciplinary use of environmental data. It is able to generate an atmospheric profile in real time, carried out by automatic Lidar ceilometers (ALC) installed throughout Italy. A database with measurement results from previous ...
Program: Operational Program «Competitiveness, Entrepreneurship and Innovation», under the call RESEARCH – CREATE – INNOVATE Starting date: 25/05/2018 Duration: 36 Μonths Summary: The object of the project is to develop the know-how and subsystems required for the construction of the first global lidar trading system for the simultaneous measurement of aerosols and ...
MPL data characterizes low clouds by creating a detailed vertical profile, enhanced by the MPL’s exceptional signal-to-noise ratio and depolarization capabilities. ...
Without insulation, heat will be radiated into the atmosphere. Kiln insulation bricks can well solve the problem. Refractories are non-metallic insulation materials that retain their strength at high-temperature. ...
Brazil lacks sufficient radio sounding, met stations, radars, and atmospheric profiling to effectively downscale GWDs. The tropical climate is characterized by small-scale, convective precipitation events caused by rapid surface heating and cloud formation. ...

To help alleviate this serious problem, scientists at Bubbleology Research International (BRI) have developed an approach that combines data from multiple instruments to better understand pollution (gases and aerosols) sources and their movements in the atmosphere. In a recent emissions study, BRI used aerosol profile data in a plume inversion model to more ...
The efficiency of the CMB model for source contribution estimate is determined by the availability of accurate source profiles and therefore its use is limited when source profiles are not known. ...
Air samples were collected from the three locations and analyzed following the standard methods. The results showed that the atmospheric PCDD/F level in Longtang was 159.41 pg · m−3, which was about 16–17 times higher than its neighborhoods and 2–4 orders of magnitude higher than baseline levels reported for urban cities of the world. The homologue profiles were ...
Observations include measurements of boundary layer winds using Atmospheric Systems’ 4000 Series minisodar; profiles of temperature, relative humidity, and liquid water from Radiometrics’ MP3000 microwave radiometer; cloud base heights and boundary layer heights collected using Vaisala’s CL-31 ceilometer; sea surface temperature; wave height and ...
The miniSODAR is a high-frequency Doppler sodar system that was designed to measure the atmospheric wind profile from 15 meters to 150/200 meters (data is often available to 250 meters) in 5-meter increments. ...
Meteorological data, including wind speed, wind direction, temperature, sigma-theta and sigma-w, were available from an on-site tower at the 33-m level. Atmospheric stability and wind speed profiles were influenced by the smooth snow-covered tundra surface with negligible levels of solar radiation in the autumn months. ...
The evaluation of mesoscale model simulations against experimental data on the vertical profiles of mean meteorological parameters and surface turbulent momentum and heat fluxes for Sofia, Bulgaria, is presented. The simulation of the vertical profiles is currently a weak point in mesoscale modelling, and needs investigation in view of the numerous practical ...
In the framework of COST-710, working group III aims to recommend formulations of atmospheric vertical profiles of wind, temperature and turbulence. This intermediate report gives a brief overview of existing methods to calculate vertical profiles. A short note on existing datasets for validation purposes is given.Keywords: ...
When using the LI-8150 Multiplexer with the LI-8100 Analyzer Control Unit, atmospheric CO2 profile measurements can be performed in addition to soil CO2 flux measurements, with minimal added cost. This application note provides a brief theory on CO2 profiling measurements and explains the LI-8100 hardware requirements and setup as well as ...
