metal-organic frameworks
Stories on metal-organic frameworks (MOFs), which have the highest surface area of all known materials, high porosity and selective absorptivity
-
Soil moisture sensors can help farmers save water, by letting them know when their crops actually need to be watered. A new sensor could be particularly helpful, as it incorporates a special material which makes it highly sensitive to moisture.
-
With the world focused on addressing climate change, scientists have had to get creative when it comes to developing sustainable building materials that tackle CO2 emissions. A team has now engineered wood that is stronger and traps carbon dioxide.
-
While the purification of wastewater once just involved the removal of traditional pollutants, it now also entails the removal of microplastics. A new powder reportedly does the job much quicker and more thoroughly than has previously been possible.
-
Engineers at the University of Vienna have developed a new composite material that makes an efficient filter for removing organic pollutants from water. The system uses super-porous “nano-sponges” embedded on a sheet of graphene.
-
Scientists have developed an efficient new way to convert methane into methanol at room temperature. The technique could help reduce greenhouse gas emissions and provide a cleaner way to make key products.
-
Researchers at Australia’s CSIRO have demonstrated a method for protecting the integrity of vaccines against high temperatures. A proof-of-concept study has shown the method keeps vaccines viable at temperatures up to 37 °C (98 °F) for three months.
-
Engineers at Dartmouth College have developed a new crystal structure that can stretch to twice its size when it encounters a specific chemical. The team says that the material could be used to selectively absorb impurities in water.
-
Researchers have developed a new type of vaccine against urinary tract infections that has shown promise in tests in mice. The treatment uses a whole dead bacterial cell, wrapped in a protective cage, to trigger an immune response.
-
Researchers at Lancaster University have developed a new material that can store energy for months, and potentially years, at a time. The material can be activated by light, and then release the pent-up energy on demand in the form of heat.
-
Getting CRISPR into cells can be challenging. Now Australian researchers have packaged the tool inside porous materials called metal organic frameworks (MOFs) coated in a green tea compound, and used it to silence key genes in prostate cancer cells.
-
It's a quandary – leafcutter ants cause a great deal of damage to crops, but applying pesticides to those crops harms the environment. Scientists have developed a possible solution, in the form of a high-tech material that uses an odor to trap ants.
-
Clean drinking water is a need that’s going unmet for many people. A new study has used a metal-organic framework (MOF) to filter pollutants out of seawater, generating large amounts of fresh water per day while using less energy than other methods.
