One option is to use clean sources of fuels called biofuels, which can be produced from natural sources such as biomass. The plant-based polymer cellulose is the most abundant form of biomass globally and can be converted into raw materials such as glucose and xylose for the production of bioethanol (a type of biofuel). But, this process is challenging owing to the molecule\u2019s rigid and dense structure, which makes it insoluble in water. Chemists and biotechnologists globally have used conventional techniques like microwave radiation, hydrolysis, and ultrasonication to degrade this polymer, but these processes require extreme conditions and are thus unsustainable.<\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\">\u00a0<\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"text-justify:inter-ideograph\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">To this end, in a new study published in <\/span><span class=\"MsoHyperlink\" style=\"color:blue\"><span style=\"text-decoration:underline\"><i><span style=\"font-family:&quot;Calibri&quot;,sans-serif\"><a href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.energyfuels.0c01069\" style=\"color:blue; text-decoration:underline\">Energy &amp; Fuels<\/a><\/span><\/i><\/span><\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">, a research team in Japan, including Dr Takayasu Kawasaki (Tokyo University of Science), Dr <\/span><span style=\"background:white\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Heishun Zen (Institute of Advanced Energy, Kyoto University), Prof Yasushi Hayakawa (Laboratory of Electron Beam Research and Application<\/span><\/span><span style=\"background:white\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">, <\/span><\/span><span style=\"background:white\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Institute of Quantum Science, Nihon University), Prof Toshiaki Ohta (SR Center, Ritsumeikan University), and Prof Koichi Tsukiyama (Tokyo University of Science)<\/span><\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">, developed a novel technique for cellulose degradation.<b> <\/b>This technique was based on a type of laser called the infrared-free electron laser (IR-FEL), whose wavelength is tunable in the range of 3 to 20 \u03bcm. This new method is a promising green technology for the zero-emission degradation of cellulose. Dr Kawasaki says, \u201c<i>One of the unique features of the IR-FEL is that it can induce a multiphoton absorption for a molecule and can modify the structure of a substance. So far, this technology has been used in the basic fields of physics, chemistry, and medicine, but we wanted to use to spur advances in environmental technology<\/i>.\u201d<\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\"><img decoding=\"async\" alt=\"Default Alt text\" class=\"media-element file-default\" title=\"Default Title Text\" src=\"https:\/\/insights.cactusglobal.com\/sites\/default\/files\/Capture_16.JPG\" \/><\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\">\u00a0<\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"text-justify:inter-ideograph\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">The scientists knew that IR-FEL<\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\"> could be used to <\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">perform dissociation reactions on various biomolecules. Cellulose is a biopolymer composed of carbon, oxygen, and hydrogen molecules, which form covalent bonds of varying lengths and angles with each other. The polymer has three infrared bands at the wavelengths of 9.1, 7.2, and 3.5 \u03bcm, which correspond to three different bonds: the C\u2212O stretching mode, H\u2212C\u2212O bending mode, and C\u2212H stretching mode, respectively. Based on this, the scientists irradiated powdered cellulose by tuning the wavelength of the IR-FEL to these three wavelengths. Then, they analyzed the products using techniques such as <\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">electrospray ionization mass spectrometry and synchrotron radiation <\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">infrared <\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">microscopy<\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">, which revealed that the cellulose molecules had successfully decomposed into glucose and cellobiose (precursor molecules for bioethanol production). Not just this, their products were obtained at high yields, making this process extremely efficient. Dr Kawasaki explains, \u201c<i>This was the first method in the world to efficiently obtain glucose from cellulose by using an IR-FEL. Because this method does not require harsh reaction conditions such as harmful organic solvents, high temperature, and high pressure<\/i>, <i>it is superior to other conventional methods.<\/i>\u201d<\/span><\/span><\/span><\/span><\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\">\u00a0<\/p>\n<p style=\"margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Apart from generating biofuels, cellulose has several applications\u2014for example, as functional biomaterials in biocompatible cell membranes, antibacterial sheets, and hybrid paper materials. Thus, the new method developed in this study shows promise for various industries, such as healthcare, technology, and engineering. Moreover, <\/span><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Dr Kawasaki is optimistic that their method is useful to process not only cellulose but also other wood constituents and can prove to be an innovative method for recycling forest biomass. He concludes, \u201c<i>We hope that this study will contribute to the development of an \u2018oil-free\u2019 society<\/i>.\u201d<\/span><\/span><\/span><\/p>\n<p style=\"margin:0in 0in 0.0001pt\">\u00a0<\/p>\n<p style=\"margin:0in 0in 0.0001pt\"><strong><span style=\"font-size:12pt\"><span style=\"tab-stops:130.5pt\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-size:11.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Reference <\/span><\/span><\/span><\/span><\/span><\/strong><br \/><span style=\"font-size:12pt\"><span style=\"tab-stops:130.5pt\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-size:11.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Title of original paper: Cellulose Degradation by Infrared Free Electron Laser<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"tab-stops:130.5pt\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-size:11.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">Journal: <i>Energy &amp; Fuels<\/i><\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-size:11.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">DOI: <span class=\"MsoHyperlink\" style=\"color:blue\"><span style=\"text-decoration:underline\"><a href=\"https:\/\/pubs.acs.org\/doi\/abs\/10.1021\/acs.energyfuels.0c01069\" style=\"color:blue; text-decoration:underline\">10.1021\/acs.energyfuels.0c01069<\/a><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin:0in 0in 0.0001pt\">\u00a0<\/p>\n<p class=\"Default\" style=\"margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"font-family:Calibri,sans-serif\"><span style=\"color:black\"><b>About The Tokyo University of Science<\/b><\/span><\/span><\/span><\/p>\n<p style=\"text-align:justify; margin:0in 0in 0.0001pt\"><span style=\"font-size:12pt\"><span style=\"text-justify:inter-ideograph\"><span style=\"font-family:&quot;Times New Roman&quot;,serif\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\"><a href=\"https:\/\/www.tus.ac.jp\/en\/mediarelations\/\">Tokyo University of Science<\/a> (TUS) is a well-known and respected university, and the largest science-specialized private research university in Japan, with four campuses in central Tokyo and its suburbs and in Hokkaido.
