CO2 extraction from the atmosphere vs the ocean Direct air capture systems currently work by taking CO2 directly out of the air and removing it directly from the atmosphere where it contributes to global warming. While atmospheric direct air capture has a positive effect on the environment, it is also a relatively energy intensive process […]
The importance of leak testing in the hydrogen economy Although cleaner than hydrocarbons when used as a fuel, hydrogen also causes about 10 times more atmospheric warming than CO2 when leaking from infrastructure. Therefore, minimizing hydrogen leaking is of great significance from hydrogen generation to hydrogen storage to hydrogen use. As a result, as the […]
Why is hydrogen gas purification necessary? The growth of the hydrogen economy is driven by the development of many hydrogen production sources, including blue, gold, green, yellow, red, turquoise, brown, black, orange, and white hydrogen. Depending on which production source is used, the refinement and purification of hydrogen gas may be a required postproduction step for […]
Since the 1970’s, researchers have been creating hybrid hydrogen and diesel engines. In 2022, engineers from UNSW Sydney successfully retrofitted a diesel engine to run as a hydrogen-diesel hybrid engine at an incredible ratio of 90% hydrogen to 10% diesel by energy fraction. Compared to conventional diesel engines, hybrid hydrogen-diesel engines, also referred to as […]
Chromatography and spectroscopy are two major techniques used to perform quantitative and qualitative analysis of gas and liquid samples. Various sample analyzers based on these methods have been developed, differentiated by features and specifications such as: Type(s) of detectors used Type(s) of phase chemical used Operating temperature and pressure conditions Ionization method (in mass spectroscopy) […]
Environmental concerns about global warming have led to the development of emerging technologies to mitigate new emissions of greenhouse gases. Although reducing these new emissions helps to reduce the magnitude of global warming, it does not reduce the impact of previous emissions which are already in Earth’s atmosphere. A practical solution to lower previous carbon […]
The plant oil market sells over 14 billion dollars per year in the United States. Various plants contain many useful oils important for medicinal, aromatherapy, skin care, and food applications. Some examples of these uses include: Aloe vera extracts for skin treatments Peppermint oils as miticides Lemongrass oils as antimicrobials Orange blossom oil for fragrance […]
Plasma-enhanced CVD is the most popular current technique for making lab-grown diamonds. The main subtypes of modern plasma-enhanced CVD include: DC plasma jet Microwave plasma RF plasma A lesser-known subtype of plasma-enhanced CVD existing since the 1990’s which operates at ambient and positive pressures and has higher theoretical diamond growth rates than previous subtypes is […]
The production of cement, the binding element in concrete, accounts for 7% of total global carbon dioxide (CO2) emissions. Concrete is one of the most-used resources on Earth, totaling an estimated 26 billion tons produced annually worldwide. Due to global demand growth, production isn’t expected to slow down for at least two more decades. Concrete […]
CO2 is considered the primary fossil fuel emission related to global warming for many different manufacturing and chemical applications. As a result, there is much research to develop more efficient methods to reduce CO2 emissions through means of carbon capture, sequestration, and conversion. In contrast, ethanol is a well-known inebriant, disinfectant, and energy source. In […]
