The Indian Institute of Technology Guwahati (IIT-G) on Monday said its researchers have formulated efficient ‘pincer’ catalytic systems that transform industrial/biomass wastes into valuable chemicals.
According to the research team, tiny amounts of these ‘pincer catalysts’ repeatedly convert large amounts of industrial waste such as glycerol into lactic acid and hydrogen.
Such catalysts also efficiently convert bioethanol, a low-energy-density fuel, into high-energy-density butanol.

“Pincer catalysts are complex molecules in which, an organic moiety holds on tightly to a metal core, much like the claws of a crab,” Dr. Akshai Kumar Alape Seetharam from the Department of Chemistry and Centre for Nanotechnology, IIT-G, said in a statement.
The conversion of valuable intermediates such as glycerol and ethanol, produced during the processing of biomass, into industrially useful chemicals has elicited much interest worldwide, the IIT-G said.
Glycerol, for example, which is a by-product in biodiesel production, can be transformed into lactic acid and hydrogen, the former used extensively in food, pharmaceutical, cosmetic, and polymer industries, and the latter in the energy sector. Likewise, ethanol obtained from biomass can be converted into high-quality fuel.
While bioethanol has lower energy density than gasoline and corrodes engine parts when used directly, it can be transformed into higher energy butanol that is immiscible in water and non-corrosive in nature.

The conversion of glycerol and ethanol into such useful products hinges on the development of efficient catalysts that can bring about these transformations. The research team rationally designed and tested a large library of “pincer catalysts” to be used for these transformations.
The experiments were carried out under environmentally benign conditions without the use of hazardous reagents and solvents. The most efficient “pincer catalyst” was found to be one that had the least crowding around the metal center.
Such an arrangement enabled easy removal of hydrogen from the starting materials, glycerol and ethanol, and their selective conversion into lactic acid and butanol, respectively.

The results of the experiments have been validated by theoretical studies. Their findings have recently appeared in the Royal Society of Chemistry journals, Chemical Communications, and Catalysis Science & Technology.
The research team plans to take these bench-scale reactions to pilot-plant scale and ultimately to the commercial level with industrial collaboration. The research team believes that the work will have a global impact on the commercial production of lactic acid/biofuels and their multi-billion dollar market worldwide. (IANS)
Heinz has just rolled out a new product that the condiment company says is the "biggest innovation in sauce since the packet itself." Earlier this month, the world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.
"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.

This announcement could be part of the fast-tracked, "future-focused culinary and packaging innovations" that Steve Cornell, president of Kraft Heinz's US grocery business unit, hinted at earlier this year amid a shortage of ketchup. A surge in takeout and delivery food orders during the pandemic led to a scarcity of ketchup packets, the report said.
In April, Heinz pledged to increase production of ketchup by 25 per cent to 12 billion packets annually. "Gone are the days of fumbling with ketchup packets, pants ruined by mustard disasters, and minutes taken off your life trying to get to the bottom of that mayo packet. With the patent-pending Heinz Packet Roller, what was once taxing becomes simple -- just snip and roll to squeeze out every drop of your sauce of choice," the website says

Swiss tennis ace Roger Federer, who is recovering from a right-knee surgery he underwent last month, said on Sunday that it was a difficult process to decide whether to undergo a third right-knee surgery after having two last year. But following Wimbledon, where he was "really unhappy" with his performance in reaching the quarterfinals, Federer opted to go through with it.
Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.
"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.

"I've got to first walk again properly, run properly and then do the sidesteps and all the agility work and then eventually I've got to be back on the tennis court. But it's going to take me a few more months and then we'll see how things are at some point next year. "I've got to take my time. I don't want to rush into anything at this point. This is also for my life. I want to make sure I can do everything I want to do later on. There's no rush with anything, so I'm actually in a really good place. I think the worst is behind me. I took the time and, I don't know, I'm just really in a good place. I'm really happy."
Federer received thunderous ovations inside Boston's TD Garden, where he has often been sitting in the front row watching the action or behind the scenes visiting with the players. The former world No. 1 has played in the first three editions of the Laver Cup. "I think Boston is a great city. The stadium is wonderful, the crowds have been incredible. Both teams are stacked with absolute quality and top players," Federer said. "That's what the idea was behind it: that everybody could come together, have the most incredible weekend, learn from one another and then hopefully that's going to inspire them, motivate them and get them going for the rest of this year, next year."

Cleopatra, was regarded as a great beauty, to preserve her skin, she took her daily bath in donkey milk. Besides, Hippocrates, the father of medicine, prescribed donkey milk for various diseases including fever, wounds, etc. To add to these benefits, donkey milk has four times the amount of Vitamin C than cow's milk has. So, it's no secret that donkey milk is a powerhouse of nutrients for both the skin and body.
Used for Anti-Ageing and Healing
The milk contains essential fatty acids that work as powerful anti-ageing and healing properties. These fatty acids blur the wrinkles on the skin and help to regenerate damaged skin. Plus, donkey milk also contains anti-bacterial properties which are effective in healing skin irritation and redness.

Antioxidant and Nutrient-Rich
Known as a "natural elixir of youth", donkey milk is packed with antioxidants and nutrients. It contains vitamin E, amino acids, vitamins A, B1, B6, C, E, Omega 3, and 6. These properties together make it a rich ingredient when it comes to skin treatment. Moreover, vitamin D is another important ingredient for human skin, and the primary source to get it is through UV exposure. At the same time, too much of that leaves an adverse effect on the skin. Here is when donkey milk acts as a great substitute as it naturally contains vitamin D. All in all, if this milk is applied frequently, it brings a glowing effect while making the skin look brighter.
