The hottest scientist invented the desert self res

According to the daily mail of March 22, scientists at the Massachusetts Institute of technology have developed a life-saving device that can fetch water in the desert. This technology has been tested in the Tempe area of Arizona, which can convert the water in the air into drinking water after treatment. As long as there is water in the air, you can get water in the desert

MIT researchers say the new device will help maintain the survival of people in arid areas. The journal Life Sciences in space research first reported this technology in 2017, which attracted widespread attention in the scientific community, with both supportive and skeptical voices

Professor Evelyn Wanger said, "while this technology has gained fame, it has also been questioned. But we have made clear answers to all the questions raised last time in the paper."

the latest research and development achievements have been tested in Tempe, Arizona, and have been confirmed that the device can take water in desert areas. Analysts say: "There is a new metal organic skeleton compound. This equipment uses this latest material, and it can extract drinking water even when the air humidity is only 10%. The existing water intake methods, such as fog water intake and dew cooling, all require air humidity of 100% and 50%. These technologies require a lot of energy for cooling and water intake. But the new device can complete the water intake task in the desert with extremely low air humidity."

compared with other water intake devices, this device is easier to maintain, and no impurities have been detected in the water in the current experiment. These small primary testing devices can only take out a few milliliters of water to prove that the theoretical concept is feasible, but the ultimate goal is to produce a large amount of drinking water for people in arid areas. Professor Wanger said that the next step would be to further improve the device and take out more water

metal organic frameworks, referred to as MOFs, are organic-inorganic hybrid materials with intramolecular pores formed by self-assembly of organic ligands and metal ions or clusters through coordination bonds

in the past few years, different types of MOFs materials have been prepared and have important applications in hydrogen storage, gas adsorption and B. separation after sudden power failure in experiments, sensors, drug release, catalytic reactions and other fields. With the increasing variety of MOFs materials and the gradual rise of composite MOFs materials in the old hydraulic universal testing machine with oil cylinder and pointer, MOFs materials will have an inestimable application prospect. In terms of gas adsorption and separation, the synthesis of MOFs materials with higher adsorption performance for hydrogen storage, toxic and harmful gas adsorption and separation can solve some of the increasingly serious environmental problems faced by people. In terms of catalytic application, the use of different metals to mix and construct composite MOFs materials with high catalytic function will further improve the catalytic efficiency. In addition, in the field of separation, the preparation of magnetic composite MOFs materials can be used for the adsorption and separation of toxic and harmful substances, heavy metals, and the extraction and separation of target proteins in complex systems. Especially in the biomedical field, due to its controllable pore size, functional groups and good biocompatibility, nano MOFs materials are prepared for drug release and metabolism in living cells, real-time monitoring of biological activities, etc., which is helpful for people to understand the important biological activities in organisms (such as protein function, protein interaction) It is of great biological significance to regulate the activation mechanism of proteins and protein regulatory pathways related to major diseases. Therefore, the development of MOFs and composite MOFs materials with functional diversity and their application in the field of calibration of hardness testers with standard blocks before measurement will greatly promote the mutual development of disciplines

mofs has been exaggerated by top magazines such as nature and science, and its scientific significance is far greater than its practical significance

mofs have amazing similarities with nano materials, C60, graphene, etc. Like them, MOFs is also a female star "touted" by nature and science. New MOFs have been synthesized, characterized and published one after another, and the database has been gradually enriched. A large number of watered articles have been published by publishers such as eswell 2.2 comparison rules, Springer, Willie, etc. I really hope that the current situation of MOFs is the accumulation stage of original materials, rather than entering the bottleneck period
