The risk of explosion is ever-present when handling powders and combustible bulk solids. Every day, around the world, process technicians and engineers estimate and minimise this risk. Nevertheless, devastating dust explosions are all too frequent. So-called "hot-spots" sudden spontaneous combustion, smouldering and glowing fires or explosion risks lurk at every stage of the storage, processing and transportation of combustible powders. In today's cement industry, more and more so-called high volatile coal and its blends are popular for kiln and precalciner firing.They are extremely flammable. As an effective preventive explosion protection Yara has developed different technological systems based on inert gases C02 und N2. These emergency inerting systems have been supporting the worldwide cement industry for more than 35 years. Each system is designed and manufactured according to individual customer needs, specifications and risk analysis. Local directives and conditions are strictly observed, they do play an important role for the engineering and conception of the systems. [ABSTRACT FROM AUTHOR]

Summer Technik presents the new compact minimal atomizer ZMIN-F1000 for efficient and low-maintenance optimization solutions in the areas of vacuum, fluid, and compressed air technology. Thanks to its flexible spray hose and various spray heads, the atomizer can reach remote cavities and angles and spray with optimized energy and low consumption. The shut-off valve of the atomizer opens as soon as it is pressurized with compressed air, and the spraying process can be individually adjusted. Sommer-Technik also offers a free ten-day trial period for interested customers. [Extracted from the article]

The article focuses on the advantages of ultrasonic leak detectors in safe detection and formulas developed for gas leak detection ranges. It states that the ultrasonic detectors can detect the leaks based on the ultrasound from the escaping gas. It says that ultrasonic detectors allow the leaks to be stimulated while technicians can produce leaks using an inert gas as a proxy. It adds that ultrasonic detectors lend themselves for modeling large leaks.

The article offers information on the importance of protecting data centres from the threat of fire. It mentions that to shut down equipment at the earliest sign of fire will block the development of corrosive combustion gases. It states that chemical extinguishing agents and inert gas are the two most suitable kinds of gas extinguishing solutions for data centres.

The article presents a discussion on the use of endoillumination for vitreoretinal surgery that improve tissue visualization, adapted from doctor David R. Chow's presentation at the 2017 World Retina Congress. It tackles the introduction of xenon light sources, the effects of filters on safety, brightness and tissue visualization, and phototoxicity from the light source in vitreous surgery.

The article focuses on the issues regarding the closure of the Federal Helium Reserve which is set to cease operations on October 7, 2013 and the impact of not passing a legislation to store helium at the Bush Dome Reservoir on the supply of helium in the U.S. It states that the shortage in the helium supply will impact the working of scientists and industries that use the nuclear magnetic resonance (NMR) machines. It focuses on the measures adopted by the U.S. House of Representatives.

The article discusses the study carried out to find the effect of lens on the efficiency of ion transfer between the quadrupole mass analyzers and the Q2 collision cell in a triple quadrupole mass spectrometry (MS). Q2 is aradio frequency (RF) only non-mass filtering quadrupole which contains inert gases like argon, helium and nitrogen whereas using lens involves a collision cell around Q2 with narrow apertures to limit gas flow. It also informs that the lens free technique is more efficient.

The article informs that a new report from IHS has revealed that market for helium is forecasted to grow 2% per year in coming years amid oversupply conditions. It is noted that supply shortages in helium prevailed from 2011 to 2013, but the market has since shifted to a glut since new supply has come onstream and traditional helium users have replaced or recycled the gas.

The article reports on the invention of a powder nozzle by additive maker O.R. Lasertechnologie that deposits the cobalt-chromium-based alloy Stellite onto sensors. It cites the welding technique used by the company to deposit Stellite powder coaxially with the laser beam. It also used the cladding method of direct metal deposition to prevent melting of the sensor material and Stellite. To prevent the generation of gas bubbles, the deposition was done in a chamber of the noble gas argon.

The article reports that problems for manufacturers of semiconductors and the devices they power could be created by a shortage of neon gas beginning in 2017. It is mentioned that a laser-enabled photolithography technique to create transistors and other device feature is used by producers of the latest computer and cell phone chips.

The article highlight the awarding ceremony where the American Chemical Society and the Canadian Society for Chemistry designated the work of Neil Bartlett that established the noble gas reactivity as an International Historic Chemical Landmark in Vancouver, British Columbia. Barlett, has prepared a compound of an inert gas called xenon hexafluroplatine at the University of British Columbia in 1932. With this, the university was presented a commemorative bronze plaque at the ceremony.

The article reports that a new calibration chamber from OPTA-PERIPH Co. is claimed to prevent contact between the standard and sample, thus simplifying calibration procedures for analyzer blend certification. The calibration cylinder supplied for 10 dm3 to 1,000 dm3 volumes features a floating double piston barrier separating the standard from the motive fluid. The interseal chamber can be filled with a low-pressure antioxidant fluid, typically nitrogen or helium. This patented double seal and bleed device prevents weathering, vapor loss, bubble, flash, oxidation and blanket offgassing.

The article focuses on the abundant supply in the global helium market created by expanded production in Qatar as of November 2015. Topics covered include the involvement of the U.S. Bureau of Land Management (BLM) in selling federally owned helium, the impact of shortages on demand for some major helium applications and the attempt by industrial gases companies to increase helium supply.

The article focuses on a study according to which structural changes occur in nanosized clusters of noble-gas atoms and when the clusters' size approaches 100,000 atoms they show a transition from face-centered cubic (fcc) to hexagonal close packed (hcp).

The article reports on the study by Leonid Khriachtchev of the University of Helsinki in Finland and colleagues that synthesized what they believe to be the smallest neutral molecule with two noble gas atoms. Researchers' synthesis involving ultraviolet photolysis of water in solid xenon, provides scientists the opportunity to study unusual properties of xenon-oxygen bonds. In 2003, they also produced the first noble-gas hydride containing two xenon atoms using computational methods.

The article reports that development of the first commercial pebble bed nuclear reactor has moved a step closer following the allocation of funding by the South African government. It is thought to have provided around $100 million to the developers, Pebble Bed Modular Reactor (PBMR) Pty, for its revolutionary and, it is claimed, inherently safe reactor design. The South African government wants to produce 4GW to 5GW of power from pebble bed reactors. The PBMR is claimed to he an inherently safe design for a nuclear reactor, thanks to its use of silicon carbide coated particles of enriched uranium oxide fuel in pebble form, cooled by helium. In the event of a systems failure the plant will shut down and heat will dissipate inside the reactor, PBMR Pty claims.
