  • Optimize capture of CO2 from seawater with flow and pressure regulation

    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 […]

  • Automating pressure swing adsorption of hydrogen gas

    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 […]

  • Hydrogen and diesel hybrid engine testing

    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 […]

  • Gas chromatography, liquid chromatography, and mass spectroscopy flow control

    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) […]

  • Flow control in direct air capture

    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 […]

  • Extracting botanical oils

    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  […]

  • Lab-grown diamond manufacturing with laser-plasma CVD 

    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 […]

  • Sequestering CO2 in concrete 

    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 […]

  • Converting CO2 to ethanol flow

    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 […]

  • Improving MOCVD with mass flow and pressure control

    Chemical vapor deposition (CVD) describes various methods to create functional coating layers using volatile gas phase compounds. There are many different types of CVD, including but not limited to MOCVD, ALD, CVI, and PECVD. Metal organic chemical vapor deposition, or MOCVD, describes CVD which uses metal complexes with organic ligands as precursors. As in other […]
