From scraps to sips: Biomass-based hydrogel pulls drinking water from thin air

Discarded food scraps, stray branches, seashells and many other natural materials are key ingredients in a new system that can pull drinkable water out of thin air developed by researchers from The University of Texas at Austin. This new "molecularly functionalized biomass hydrogels" system can convert a wide range of natural products into sorbents, materials that absorb liquids. By combining these sorbents with mild heat, the researchers can harvest gallons of drinkable water out of the atmosphere, even in dry conditions. "With this breakthrough, we've created a universal molecular engineering strategy that allows diverse natural materials to be transformed into high-efficiency sorbents," said Guihua Yu, a professor of materials science and mechanical engineering and Texas Materials Institute at UT Austin.

Researchers discover new material to 'trap and store volatile gases'

Researchers at University of Limerick in Ireland have discovered a new material that can 'trap and store' volatile gases.

The research team, which includes international collaborators in Japan, the US and South Africa, have discovered a new class of porous materials or sorbents for trapping and storing volatile gases.

The discovery has just been published in the journal Nature Chemistry.

The team is led by Dr. Varvara Nikolayenko, formerly of the Department of Chemical Sciences and UL's Bernal Institute, now working at Bayer AG and Professor Michael Zaworotko, Bernal Chair of Crystal Engineering and Science Foundation of Ireland Research Professor at UL's Bernal Institute.

Bro-Tex is a family-owned manufacturer and supplier of wet wipes, shop towels, cloth/paper wipes, microfiber towels, rags, and sorbents. We have been supplying schools and businesses for over 100 years with over 400 janitorial cleaning products and maintenance wipes. Our wipes are using for disinfecting surfaces, wiping up spills, dusting, degreasing grimy hands, and cleaning up after painting/maintenace projects.

Have you ever thought about the power of a word? Since ancient times bright speeches and combative discussion were changing the destiny of entire nations. What if a single letter is more powerful than thousands of words? What if one letter is able to save thousands of lives and drastically reduce environmental problems?

  A lot of people use similar words interchangeably, having no idea that their meanings are significantly different and instead contribute to the ongoing inaccuracies taking place. To take such words as ‘absorbent’ and ‘adsorbent’, for example. At first, it seems they are special sounding, almost the exact same. The problem is that their incorrect use can lead to serious environmental damage during spill prevention and response operations.

  According to German physicist HeinrichKayser, aDsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. It is a surface phenomenon.

  aBsorption is a physical phenomenon or a process in which atoms, molecules, or ions enter some bulk phase – gas, liquid, or solid material. This is a different process from aDsorption, since molecules undergoing aBsorption are taken up throughout the volume of the aBsorbent material, not by the surface evenly distributing throughout.

  The main difference between these two terms is that aBsorbent materials lock the liquid inside (capture and contain) each molecule and do not release the liquid through compression, gravitational pull, or even when cut in half. Absorbents are able to absorb/imbibe liquids in volumes greater than of their own because as the material aBsorbs it swells. aDsorbents do not swell therefore cannot adsorb volumes greater than their own.

  Take care of the environment - when responding to hydrocarbon spills make sure the products you use completely capture and contain and do not lead to secondary contamination of ground/water or people.
