Measuring CO2 to Optimise the Bulk Storage of Food
Meeting the food requirements of a growing global population is becoming increasingly difficult. Despite the need for additional food, it is estimated that 50-60% of grain is lost after harvesting, at a cost of about $1 trillion per year.1 One of the major reasons for lost grain is spoilage due to mould or insect infestation during storage.2 To provide a constant supply of grain year-round, after ...

Carbon Dioxide Levels and Safety Considerations in Winemaking
Although, at first sight, winemaking might appear to be one of the most idyllic of occupations, it is an industry with its own serious safety concerns. The fermentation process that produces the highly desirable end product, whether it be a serious earthy, rich, Cabernet Sauvignon or a sweet, slightly decadent, Moscato, also produces a lot of carbon dioxide. In the realm of 40 times the volume of ...

The Importance of Having a Cleanroom
Any industry where small particles interfere with manufacturing processes needs cleanroom panels within their systems. They control the contamination level as well as humidity, pressure and temperature in various factories. Most cleanrooms differ in size and complexity in that setting, such as those of a biotech or pharmaceutical industries have more controlled environments than others. Remember ...

Do plants improve air quality?
According to an often-quoted study conducted by NASA, house plants have been found to purify the air and remove “up to 87% of the amount of toxins in the air”. Recent studies, however, have cast doubt on these statements finding that indoor plants actually have no significant effect on improving indoor air quality (IAQ). What is the real scientific evidence behind these claims, and ...

New Mandatory CO2 Thresholds in the Workplace - What does the impending legislation say?
In a sign of what the new post-Covid normal will look like, the Irish government is preparing to legislate for mandatory CO2 thresholds in the workplace. The Workplace Ventilation (Covid-19) Bill 2021 is at its Third Stage in the Houses of the Oireachtas. No longer a mere recommendation, if passed, every employee will be entitled to fresh air as defined by an environment with less than 900ppm of ...

How Will Carbon Capture, Utilization and Storage (CCUS) Contribute to the Global Temperature Goal of 1.5°C?
Let’s begin: what Carbon Capture, Utilization and Storage is and how it works Carbon Capture, Utilization and Storage (CCUS) consist of a series of technologies to capture carbon (usually as CO2) emitted by various processes, to then either be used or stored in an underground reservoir. Carbon capture can be achieved as part of an industrial process, such as hydrogen, ammonia or ethanol ...

USP <645> - simple automated analysis of ultrapure water
H2O – two simple elements, oxygen (O) and hydrogen (H), fuse together to form one of the most important molecules in the world: water. Water is everywhere on Earth and it is vital for our health and survival. It often contains other ions like calcium, magnesium, and chloride which are essential for the human body to function. However, in specific situations, ...

The Advantage of Changeable Spectral Filters in your Optical Gas Imaging (OGI) Camera
There are two kinds of OGI cameras: cooled and uncooled. Cooled cameras, like the EyeCGas 2.0, allow us to detect small to large leaks (methane and over 400 VOCs) from various distances, up to 10 kilometers away and more. Whereas uncooled OGI technology, such as the EyeCGas Mini, is slightly limited in its capabilities, detecting medium to larger leaks (methane) closer to the source. Inside the ...

Carbon Neutrality Consultancy Services: Here’s How to Achieve Carbon Neutral Certification
As the world marks the fifth anniversary of the adoption of the Paris Agreement on Climate Change, a propitious movement for carbon neutrality is taking shape. According to the Intergovernmental Panel on Climate Change, carbon neutrality is a state of balance between CO2 emitted in the atmosphere and CO2 removed from the atmosphere. Getting to the target of net-zero emissions requires notable ...

Science: Three-megadalton complex of methanogenic electron-bifurcating and CO2-fixing enzymes
Methanogenic archaea use complex enzyme systems to survive in anoxic environments with limited energy. A key mechanism for energy conservation is electron bifurcation, a reaction that "splits" the energy of a pair of electrons, thus making one electron more reductive at the cost of the other. In a new study, researchers from the Max-Planck Institute for Terrestrial Microbiology and the ...

Gold-like activity copper-like selectivity of heteroatomic transition metal carbides for electrocatalytic carbon dioxide reduction reaction
An overarching challenge of electrochemical carbon dioxide reduction reaction (eCO2RR) is to find a highly active catalyst that can produce hydrocarbons at a high current density and a relatively low overpotential. In a recent study published in Nature Communications, Prof. Asadi and his research team at Illinois Tech have discovered a new class of catalysts that effectively converts CO2 to ...

A Guide for Effective Selection of Air Quality Monitors
The selection of air quality monitors plays an elemental role in preparing preventive and protective action plans on regional as well as global scales. In 2019, Hindustan Times kindled a discussion on the rising number of non-attainment cities across the country. That is to say, a non-attainment city fails to comply with the Central Pollution Control Board (CPCB) standards. This noncompliance is ...

Carbon Dioxide Safety: Why It`s Important to Monitor Carbon Dioxide
What is Carbon Dioxide? Carbon dioxide is the fourth most abundant gas in the earth's atmosphere after nitrogen, oxygen, and argon. At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas, but at different temperatures and pressures, carbon dioxide can be a liquid or a solid (i.e., dry ice). Carbon dioxide is produced when fossil fuels are burned, or as vegetation ...
