Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT-IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydrogen evolution. In contrast to the traditional belief, this study demonstrates that not the free electrons in metal cocatalysts but the electrons trapped in the periphery of cocatalysts directly contribute to the photocatalysis. Since the discovery of photoelectrochemical hydrogen evolution by Honda and Fujishima in 1972, heterogeneous photocatalysis has been intensively investigated and is still a hot topic in science and technology. In particular, understanding of reactive electron species and active reaction sites on photocatalytic reduction reaction are vital for designing and manufacturing innovative catalysts with improved evolution activity of hydrogen as sustainable energy carrier.

Clean energy plans, including the U.S. Infrastructure Investment Act's "Clean Hydrogen Road Map," are counting on hydrogen as a fuel of the future. But current hydrogen separation technology is still falling short of efficiency and sustainability goals. As part of ongoing efforts to develop materials that could enable alternative energy sources, researchers in Drexel University's College of Engineering have produced a titanium oxide nanofilament material that can harness sunlight to unlock the ubiquitous molecule's potential as a fuel source. The discovery offers an alternative to current methods that generate greenhouse gas and require a great deal of energy. Photocatalysis, a process that can split hydrogen from water using only sunlight, has been explored for several decades, but has remained a more distant consideration because the catalyst materials enabling the process can only survive it for a day or two, which limits its long-term efficiency and, as a result, its commercial viability. Drexel's group, led by College of Engineering researchers Michel Barsoum, PhD, and Hussein O. Badr, PhD, in collaboration with scientists from the National Institute of Materials Physics in Bucharest, Romania, recently reported its discovery of photocatalytic titanium oxide-based, one-dimensional nanofilament material that can help sunlight glean hydrogen from water for months at a time. Their article "Photo-stable, 1D-nanofilaments TiO2-based lepidocrocite for photocatalytic hydrogen production in water-methanol mixtures," published in the journal Matter, presents a sustainable and affordable path for creating hydrogen fuel, according to the authors.

Advanced Nanomaterials as UV Photocatalysts for IAQ Monitoring_Crimson Publishers

Abstract

Nowadays, indoor air pollution has emerged as a major health concern for the indoor living population. UV photocatalytic indoor air cleansing has been found to be a promising technology. Effective UV photocatalysts have been applied to monitor/control the indoor air quality (IAQ) level. The nanomaterials based on nanocarbons, polymers, and nanoparticles have been applied in the UV photocatalysts. Indoor pollutants including gaseous pollutants, organic compounds, and biological pollutants have been removed using photocatalytic technology. Basically, nanomaterials act to degrade the environmental pollutants into environmentally safe forms, i.e., least hazardous for human health and maintain the IAQ level. Accordingly, through the use of nanomaterial-based UV photocatalysts, future solutions linking the IAQ regulation to the novel nanomaterials have been achieved.

3 NASA Technologies Impacting Society and Our Way of Life 🚀

By: Science 10 Class (Group 14) - Alvarez, Dacanay, Dy, Gumatin, Sindac

Truly, NASA has always provided insight to what is yet to be known in the big wide universe. They have done this through the use of multiple tools, primarily the technologies they have invented. However, who would have known, these technologies used on their space missions are entirely beneficial in everyday life on earth. It’s fascinating how something so big and used for big projects and discoveries, are used simply in our everyday lives and bring us convenience in our chaotic lives. Thus, in this blog post, I will be discussing 3 NASA technologies impacting society and our way of life. 🪐

Communications and Phone Technologies 📱

In the 1990s, NASA built a new sensor using a complementary metal oxide semiconductor (CMOS). This is what was used to take photos in space during space missions as it is a small, highly efficient, and low-power-requiring tool. Thus, it was relatively convenient for these space missions. Consequently, with the rising digital times and the need for convenience as a human species, this CMOS technology is widely present in our digital imaging industries (Dunbar, 2019). Moreover, NASA has helped come up with portable Wi-Fi signal boosters. These were originally made to improve communication during lunar missions. However, at present, the technology is used to help increase incoming signals and improve local reception for cell phones, laptops, satellites, and Wi-Fi internet receivers without the need for power plugs, cables, or batteries. Both of these technologies have impacted society enormously (Richmond, 2024). Evidently, this has enabled the application of cameras, high-definition videos, and social media to a smaller, more compact cell phone where multiple functions are condensed. This has impacted us by making capturing and sharing photos easier, allowing for more efficient dissemination of visual information. Similarly, the invention of the Wi-Fi booster has enabled faster and more efficient communication when using Wi-Fi, allowing for better communication with others.

Home Purifiers 🧼

Air purifiers were initially designed by NASA to eliminate various toxins present in the air in order to make plants grow efficiently in space. NASA's success in the newly developed technology influenced its modification into plug-in filters to keep the indoor air cleaner and healthier (Dunbar, B., 2019). This breakthrough has opened opportunities for further innovative developments of the different air purifier purification technologies to cater to rising issues affecting public health. The existing air purification technologies are high-efficiency particulate air filters that have mineralization technology of ultra-light structure, negative (positive) ion technology, photocatalyst technology, electrostatic dust collection technology, and activated carbon adsorption technology (Wang, et al. 2015). These different technologies are utilized in various ways. During the COVID pandemic, air purifiers were used in hospitals, schools, and various establishments (NatéoSanté, 2023). In a study conducted by Zhai, et al. (2021), portable air purifiers were found to be effective in mitigating virus-carrying droplets in enclosed places. A similar research by Fermo, et al. (2021) found air purifiers to be efficient in reducing concentrations of fine Particulate Matter (PM) and Volatile Organic Compounds (VOCs) present in indoor air. The filtering of these air pollutants has impacted society and the current way of living by providing means to consistently monitor and maintain indoor air quality. This consequently minimizes and/or prevents possible illnesses or diseases.

Sustainability 🪴

Solar cells found in solar panels are one of the innovations developed by NASA to power unmanned aircraft flights. This technology was successfully launched in 1995 through the Pathfinder, the first remote-operated solar-powered aircraft to reach an altitude of 50,500 feet. Developed by the Environmental Research Aircraft and Sensor Technology (ERAST) Alliance, this invention was created to apply solar technology to power the aircraft’s electronic systems, allowing it to endure long durations and high-altitude flights for science missions (NASA Spinoff, 2005). This was followed by other prototypes including the Pathfinder-Plus, Helios, and Centurion, each of which were developed to surpass the altitude of its predecessor with the hopes of remaining airborne for weeks (National Aeronautics and Space Administration, 2014). This invention involves the creation of single-crystal silicon solar power cells which are efficient, lightweight, and cost-effective. As the world continues to face the issue of global warming, such technologies become increasingly important to integrate into daily living. As such, it impacts society by contributing to our sustainability efforts to renewable and reusable energy rather than relying on unrenewable energy sources. Moreover, it provides numerous communities with a more cost-efficient option and uses this to power their house and everyday needs (Richmond, 2024).

These are some of the few technologies that NASA has created and that we now use in our everyday lives. Many more were not listed here but are important in their own right or be the trailblazer of technology in the future. You may read more about them in the references below.
