KAWANISHI-CITY, Japan, Aug. 17, 2020 /PRNewswire/ -- Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi permanently in the atmosphere and do not get chemically or physically influenced by temperature change are major reasons for climate change. More precisely, water vapor (H2O), nitrous oxide (N2O), methane (CH4), fluorinated gas and carbon dioxide (CO2) are the major greenhouse gases that cause climate change.
Regarding CO2 over the last century, the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. Deforestation is another major reason for increasing CO2 concentration in the atmosphere which is also caused by human activity.
Metal organic frameworks (MOFs), also known as porous coordination polymers (PCPs), are materials composed of metal cations and organic ligands that bridge component metals. MOFs are synthesized as super-porous materials by modifying their metal and organic ligand, as well as the shape and size of pores. Pore size can be controlled in less than nm order and MOF possess extremely large specific surface area (1000 – 9000 m2/g) and their chemical group can be tailored at the molecular level.
With conventional porous materials such as activated carbon, zeolite, and mesoporous silica, it was difficult to create such exact porous structure with desired shape and pore size. Although with MOF, one can artificially design the structure, surface area, shape and size of the pores at the molecular level. Theoretically, MOFs can be prepared by combining numbers of metals and organic ligands; so that more than 40,000 kinds of MOFs have been already reported. Because MOFs are completely new ultimate inorganic–organic hybrid porous materials, chemical industry and academic researchers have recently been highly focused on them.
Green Science Alliance has been synthesizing various type of MOF and have been trying to apply MOF to rechargeable battery, fuel cell, water vapor adsorption, gas adsorption, metal adsorption, deodorizing, photocatalysis, artificial photosynthesis etc.
This time, Mr. Tetsuro Kajino, Mr. Hirohisa Iwabayashi and Dr. Ryohei Mori at Green Science Alliance tested various type of MOFs which is synthesized in their company and found that certain kinds of MOF have strong CO2 adsorption capability. Since they have confirmed this fact, they will try to create CO2 absorption device and artificial photosynthesis application etc… in order to challenge to solve global warming problem.

The U.S. president’s threats to seize Greenland left its people on edge, and with details scarce, the news of an agreement didn’t seem to be putting minds at ease.
Chinese action camera maker Insta360 is deepening its US footprint with a flagship store opening in New York as it navigates escalating price competition with DJI and industry-wide memory cost pressures. The Chinese GoPro rival was slated to plant its flag in the heart of Times Square with its first flagship retail store in the US on Saturday, a marquee launch as the firm looked to “leap to the next stage of growth”, co-founder Max Richter said. “The US market plays a very important role for us...
For years, the race to build ever more powerful artificial intelligence followed a well-worn Silicon Valley principle: move fast and break things. But in a series of cascading events over a 10-day stretch, the largest AI labs found themselves reeling as their own creations threatened to break humanity itself. An Anthropic researcher quit the firm, warning that the pace of AI development poses an existential threat, possibly within a decade. Another researcher at the firm said the odds of human...
A senior ally of Malaysia’s Anwar Ibrahim announced his resignation from cabinet on Saturday – a day after confidence in the prime minister’s administration took a severe hit when disgraced former leader Najib Razak was allowed to serve out his jail term under house arrest. Anthony Loke, the secretary general of the Democratic Action Party (DAP), said that the party could not accept the decision to allow Najib to complete his sentence in the comfort of his own home. The former prime minister is...
The director and writer Simon Stone updated the classic work to reflect the world we live in with this Korean-language adaptation at the Park Avenue Armory.
Years ago, I watched a focus group explain itself into a contradiction. We asked people what mattered when choosing car insurance. Price won. The deductible came next. Reputation did not appear. During coffee, I asked the interviewer to change the question. How much cheaper would a less prestigious insurer have to be before they switched? One participant, who 15 minutes earlier ranked price first, said no discount was large enough. Nothing changed except how we asked the question. Something...
Cloud seeding operations will be carried out in Selangor, Kuala Lumpur and Putrajaya following worsening haze conditions in Malaysia, according to the National Disaster Management Agency. The agency said the operations would be scheduled for Saturday and Sunday. “However, the operations are subject to weather conditions and the availability of suitable clouds for the seeding process,” its director general, Meor Ismail Meor Akim, said in a statement on Saturday. The operations will be carried out...
President Lee Jae Myung’s comments followed President Trump’s repeated demand for “a little hand” from South Korea, a decades-old American ally.
Alina B.K. should have been preparing for her end-of-year university exams, but news of devastating floods along the Nepal–Tibet border kept pulling her back to a troubling question: what kind of future awaits her? The 21-year-old forestry student, who coordinates the Pokhara network of Nepalese Youth for Climate Action, said she struggled to concentrate as reports of death and destruction deepened her fears about a changing climate. “With the floods and deaths happening around us, it is really...
The death toll from an explosion and gun attack at a police headquarters in northern Pakistan rose to at least 31, including 16 police personnel, a senior police official said on Saturday, with fighting ongoing. An attacker rammed an explosives-laden car into the Old Police Lines complex while gunmen stormed the compound on Friday afternoon as officers and their families were praying in a mosque. The police complex at Kohat, a town of around 220,000 people in Pakistan’s Khyber Pakhtunkhwa...
The young government of Nepal, a nation with a tiny carbon footprint, is seeking reparations from the world’s major economies as it bears the brunt of collapsing Himalayan glaciers.
Fears that advanced artificial intelligence could wipe out humanity have dominated global headlines, but in Japan the technology is being used for a sweeter purpose – developing never-before-seen convenience store desserts. For customers tired of the usual egg sandwiches and rice balls, major chains are turning to AI to develop products, including some unexpected flavours. Lawson, one of the country’s biggest convenience store operators, said on Tuesday it would roll out three new food items,...
