C&EN explores the alt-leather scene Chemical & Engineering News 2021-03-09 | We got hands-on with some of the materials marketed as a sustainable alternative to leather. ↓↓More info below↓↓ Leather is a maker’s dream material. It cuts well; it holds a stitch; it can be dyed, stamped, or tooled; it’s warm but breathable, strong but flexible. But it has a heavy environmental footprint. Modern tanning uses chromium salts to cross-link collagen fibers, creating large quantities of wastewater. And, of course, the hides mostly come from the meat and dairy industry, which many people consider environmentally unsustainable.So entrepreneurs are working to bring leather alternatives to market, made from plants, mushrooms, and more. These aren’t the synthetic pleathers found in cheap shoes and purses. Leatherlike textiles made from nonanimal sources, sometimes called vegan leathers, are positioned as premium products for high-end goods. C&EN reporter Craig Bettenhausen gathered several samples of materials making their way into consumer products.Read more: Sustainable materials make a play for the vegan leather market | C&ENcen.acs.org/materials/biomaterials/Sustainable-materials-make-play-vegan/99/i8 Stay up to date with the most important chemistry news!

Graphene micromotors spin forward Chemical & Engineering News 2021-01-08 | Researchers have found a way to make helical magnetic-responsive micromotors out of graphene. ↓↓More info and references below↓↓Micromotors could someday zip through wastewater picking up pollutants or race through the bloodstream delivering drugs. Researchers have developed a number of strategies, such as chemical fuels and magnetic fields, to propel these tiny devices. Now, researchers have found a way to make helical magnetic-responsive micromotors out of graphene. The carbon material is attractive for micromotors because it’s easily functionalized and possesses a high surface area. Yet adapting current methods for making helical micromotors to graphene has been challenging. To that end, the team developed a cheap, simple method to pump out the coil-shaped motors. The team investigates the motors’ ability to navigate microchannels and also kill bacteria when armed with antibacterial silver. This work combines the advantages of graphene and magnetically-powered micromotors, which are more suitable for practical applications such as environmental remediation and biosensing than chemically-powered motors, says Wei Gao, a microrobotics expert at the California Institute of Technology.

Microfluidics boost blood cell production Chemical & Engineering News 2020-10-21 | Researchers use microfluidics to purify lab-grown blood cells faster, helping study a malaria-causing parasite. ↓↓More info and references below↓↓Plasmodium vivax is the most common parasite to cause malaria in Asia and South America. It preferentially infects an immature red blood cell that accounts for only 1–2% of circulating blood. The limited supply of these cells—called reticulocytes—has made it difficult to study P. vivax in the lab. Now, researchers at the Singapore-MIT Alliance for Research and Technology report two microfluidic methods for purifying lab-grown reticulocytes, one of which calls to mind the game Plinko from game show The Price is Right. The team demonstrates that the cheap, microfluidic chip-based methods offer comparable purity and faster processing times compared with standard sorting methods. These purification methods could also help advance the field’s long-standing goal of manufacturing red blood cells for transfusions.

Flipping bubbles upside down reveals new insights on how they collapse Chemical & Engineering News 2020-09-02 | Bubbles are more complicated than you might think. ↓↓More info and references below↓↓Scientists have long believed that viscous bubbles collapse due to gravity. Now, a new study from researchers at Boston University, Princeton University, and the Massachusetts Institute of Technology turns this accepted mechanism, as well as bubbles, upside down. By flipping bubbles and watching them with high-speed cameras, the team demonstrates that how bubbles pop depends on surface tension, not gravity. This improved understanding could help scientists better control bubble formation, which could be useful in a number of applications, including spray painting and making ice cream.Read more:A New Wrinkle on Liquid Sheets: Turning the Mechanism of Viscous Bubble Collapse Upside Down | Science science.sciencemag.org/content/369/6504/685.full Stay up to date with the most important chemistry news!Subscribe to C&EN's weekly newsletter at cenm.ag/signmeup.

Carbon monoxide molecules can dance Chemical & Engineering News 2020-07-22 | When atoms or molecules collide, scientists expect them to bounce off one another like balls on a pool table. Not so when two CO molecules meet in just the right way. ↓↓More info and references below↓↓Using computer simulations, researchers found that if CO molecules meet carbon-to-carbon with a collision velocity of about 800 m/s, the two molecules will rotate in place, propelled by the oxygen atoms’ interaction as the molecules turn their “backs” to each other, before each continues on its original trajectory. The motion looks quite similar to a square-dancing step called a do-si- do, in which square dancers circle each other back to back. The effect is to turn the molecules’ forward momentum into rotational energy. The researchers say the behavior happens only in about 1 of 20 collisions, but existing models don’t account for it. In interstellar space, CO molecules are likely to emit that rotational energy as light, which is captured by the telescopes that produce images of dust clouds and nebulae. These collisions may be more common near comets and some exoplanets, which have very high CO concentrations. The researchers are now looking for other molecular dance moves.Read more:Molecular square dancing in CO-CO collisions | Sciencescience.sciencemag.org/content/369/6501/307.abstractSubscribe to C&EN's newsletter at cenm.ag/speakingsignup.
Researchers design surfaces that let them control bubbles underwater Chemical & Engineering News 2020-07-20 | Using a ferrofluid-based surface, researchers can control the motion of bubbles underwater. ↓↓More info and references below↓↓Moving gas bubbles underwater on a surface could help scientists and engineers in the lab and in industry. But it’s not an easy task. Previous methods have relied on slippery silicone oil–coated surfaces, but bubbles move slowly on these surfaces and only in one direction. Now, a team of researchers have developed a ferrofluid-based surface that lets them move bubbles quickly and in any direction with the help of a magnet. Using this so-called FLAM surface, researchers could drag bubbles down tilted surfaces and even tow objects more than 500 times their own mass. The authors envision their method being useful for applications such as electrochemical reactions and wastewater treatment.High Performance Bubble Manipulation on Ferrofluid-Infused Laser-Ablated Microstructured Surfaces | Nano Letters pubs.acs.org/doi/10.1021/acs.nanolett.0c02091Stay up to date with the most important chemistry news.Subscribe to C&EN's newsletter at cenm.ag/speakingsignup.
Microgripper captures single cells for tissue biopsy Chemical & Engineering News 2020-07-01 | Scientists have developed tiny grippers as a promising new tool for targeting single cells. ↓↓More info and references below↓↓Sampling diseased tissue, which can contain many different types of cells, calls for precise biomedical tools. Current methods for manipulating single cells, like laser microdissection, require complicated setups and can damage cells. Now, researchers have developed devices that could offer a simpler and less harmful way to isolate single cells. Remotely guided by a magnetic field, these so-called microgrippers can wrest single cells from a tissue sample and carry them on demand. Though the tiny grippers require more optimization and testing, the researchers hope one day to use them to perform single cell biopsies inside a human body.

Microrobots roll against blood flow to deliver drugs Chemical & Engineering News 2020-06-17 | Tiny microrobots could travel the bloodstream to one day deliver cancer drugs to hard-to-reach tumors deep inside the body. ↓↓More info and references below↓↓With the help of a magnetic field, these two-faced particles might one day navigate our circulatory system to deliver treatments to tumors. The microrollers are coated on one side with magnetic materials and on the other with antibodies specific to cancer cells. These antibodies would help the particles selectively bind to tumors in the body, where they could release their payload. This targeted approach could minimize exposure of healthy cells to cancer drugs, reducing side effects.

Magnetic sponge cleans oil spills Chemical & Engineering News 2020-06-05 | Researchers coated an inexpensive sponge with nanoparticles that give it oil-absorbing properties. ↓↓More info and references below↓↓ The words “sponges” and “cleanup” might evoke dirty dishes and kitchen duty. But to a team of materials scientists, they are the inspiration for a way to remediate aquatic oil spills. Researchers at Northwestern University have developed an inexpensive way to convert ordinary sponges to ones that selectively soak up oil from water. The oil can be recovered simply by squeezing the sponges.Oil leaking from tankers and pipelines harms marine life and the environment. Existing methods for treating the spills have significant shortcomings. On-site burning, for example, emits pollution and greenhouse gases. Chemical dispersants, which break up the oil into tiny droplets and scatter them throughout the water, can harm wildlife. Other methods don’t discriminate well between oil and water, or they leave the water covered with an oily sheen.Several research groups have proposed alternatives to these commercial cleanup methods, such as soaking up the oil with sponges coated with silanes, fluorocarbons, or graphene. But these lab-scale studies rely on reagents and procedures that are expensive, toxic, or unscalable.Vikas Nandwana, a research associate working with Northwestern’s Vinayak P. Dravid, and coworkers developed a simple dip-coating method to apply a composite film of graphite and iron oxide nanoparticles to polyurethane and other sponges. The coating, which can also be prepared with iron manganese oxide, is made from inexpensive, abundant, and environmentally benign starting materials and is formulated as an aqueous slurry. Applying it to standard polyurethane furniture cushions that are typically landfilled creates a sponge that selectively absorbs a wide variety of oils from oil-water mixtures while excluding water.Read more at cen.acs.org/materials/coatings/Low-cost-polyurethane-sponge-cleans/98/i22Reference:OHM Sponge: A Versatile, Efficient, and Ecofriendly Environmental Remediation Platform | Industrial & Engineering Chemistry Researchpubs.acs.org/doi/10.1021/acs.iecr.0c01493 Stay up to date with the most important chemistry news.
