New Glue That Is Remarkably Strong, yet Can be Easily Removed

December 3, 2020 by richarsm · Chemistry

This glue is so strong it can hold a chemistry Ph.D. candidate!

A new temporary adhesive has been made, which can be useful in technical applications. It can also be as strong as a polymer-based adhesive. Although polymer-based adhesives where you have to pull the glued surfaces apart, this new glue requires no force to remove it from surfaces. The key is that the new adhesives stick as a solid, but turn to a vapor once it’s heated in a vacuum environment. That process is also known as sublimation, and doing that process makes the glue have an easy release. It can help make pills work faster and smaller, which smaller pills are suitable for everyone to take. It can also help computer chips be smaller and extra powerful since the vigorous pulling of tape is no longer needed.

I believe that this new adhesive can be helpful in so many ways. It can help with making pills more effective and computer chips more powerful. I found it so interesting that this glue is so strong, but when removed, it’s an easy process and doesn’t even leave marks. With this new adhesive, it can make so many things simpler and more efficient.

Researchers examine which approaches are most effective at reducing COVID-19 spread

December 3, 2020 by richarar · Chemistry

Two professors of Simon Frazer University named Paul Tupper and Caroline Colijn Have found out that Physical distance universally has effective help reducing the spread of the virus, while social bubbles and masks are more situation-dependent. Their research said that people who are highly likely to get it from are Bars, Nightclubs, and overcrowded Workplaces, and people that have a low probability to get from are going on public transportation with a mask, social distancing at restaurants and etc. But even with the mask, they say that it can’t fully protect you from getting it from somebody, but it is best to wear it.

Well, I think that The two Professor Research information is very helpful and helps us understand which approaches are more effective to reduce Covid-19. It tells the high and low probabilities of getting the virus. Wear mask places and social distancing can help reduce a little bit of Covid- 19 instead of being close to one another and breath on each other at a club or somewhere.

Scientists Create Artificial Spider Silk

December 2, 2020 by schobeaj · Chemistry

Spider silk, the stuff they shoot out of their butts, is made out of protein-based fibers. Researchers at Kyoto University have drawn conclusions that the key to mass-producing spider silk is a combination of acidification and a process known as liquid-liquid phase separation or LLPS. The protein that is in the silk is called spidroins. A spider has a large gland where the spidroins are in their liquid state which gets expelled into the air and converts to the complex form of silk. To find out how to actually create artificial silk, scientists chose a specific spidroin called MaSp2. Once they got their protein, they put it through many different chemical conditions to see what specific chemical changes are needed for the liquid phase to turn solid. After tireless efforts, they lowered the Ph levels and that ended up forming the liquid silk into solid strands.

I think that this could really make a difference in the manufacturing world. Natural silk is expensive by itself because of how they have to get it. If people could mass-produce man-made silk at a lower cost it would surely make things easier on people. An example of this would be opals. Real ones found in nature are extremely expensive but there are also lab-made ones and they are much cheaper and just as good.

Pesticide Deadly to Bees Now Easily Detected in Honey

December 1, 2020 by tredercs · General Science

Researchers at the University of Waterloo have developed a new technique to extract harmful pesticides from honey. The pesticide is one of the main two groups of pesticides called pyrethroids. These cause a condition called colony collapse disorder, where the worker bees disappear from the hive, leaving the queen and other members to die. Not only are pyrethroids harmful to bees, but they can also be harmful to humans if used in excessive amounts. Previously, it has been difficult to extract due to its poor solubility, and because of the way it is suspended in honey. With this new method, they can not only detect the pesticide but determine which farmer it came from.

Already, the honeybee population is rapidly decreasing. Their homes are being destroyed and they are being killed by the overuse of pesticides. The fact of the matter is: they are going extinct. This is a problem because the entire agricultural economy relies on bees. Without bees around to pollinate the crops, farmers will lose billions of dollars and billions of food products. With this new method, researchers will hopefully be able to identify the harmful pesticides and help stop the rapid decrease of the bee population.

OCD Medication Turned COVID-19 Drug

November 30, 2020 by plocheal · Chemistry

Accelerated Efforts To Repurpose Approved Drugs for COVID-19 | Technology  Networks

Fluvoxamine is an antidepressant drug commonly prescribed for OCD patients. COVID-19 can cause uncontrollable inflation that can result in difficulty breathing and blood-clots. Fluvoxamine successfully works to reduce inflammation in rats and was later tested on a group of willing COVID patients. The results showed an increase in the health of many patients. Could this be the newest Corona Virus?

I think it is very important to continually work on more ways to help eliminate COVID-19. At this time we must search for more solutions. This new medication could effectively save millions. I enjoyed reading how resourceful we can be. Looking for solutions that have already been found in the science world to aid in other situations is so interesting.

New solvent-based recycling process

November 29, 2020 by linl · Chemistry

As we know, plastic has been playing an important role in our life, we can see plastic materials everywhere. But there’s an issue, they can’t be easily recycled like papers or water, and that causes another issue, pollution. Finding an effective way to recycle the plastic, have been something important that people working on for decades, and groups of engineers at the University of Wisconsin-Madison seems to have some breakthrough in this study.

A method for reclaiming the polymers in these materials using solvents, a technique they’ve dubbed Solvent-Targeted Recovery and Precipitation (STRAP) processing. By using a series of solvent washes guided by thermodynamic calculations of polymer solubility, UW-Madison professors of chemical and biological engineering George Huber and Reid Van Lehn and their students used the STRAP process to separate the polymers in a commercial plastic composed of common layering materials polyethylene, ethylene vinyl alcohol, and polyethylene terephthalate.

In my opinion, studies like this are necessary and worth doing, as the world grows more and more advanced, our environment is getting worse and worse. Without the technic of recycling plastic, tons of plastic materials in our life literally means tons of useless plastic trash after use. We should be aware of these issues before too late.

Understanding the Power of Our Sun

November 25, 2020 by shobeme · Chemistry

A star 2 million times brighter than the sun disappears without a trace |  Deccan Herald

We know that the stars produce their energy through a process called nuclear fusion (hydrogen-burning), but another way, which is actually the predominant way the sun produces energy, is through a process called the pp (proton-proton reaction) cycle and another called the CNO (carbon, nitrogen, oxygen) cycle. Although the pp cycle has been the predominant energy source for the sun, new research is showing that the CNO cycle could be the most predominant in most large stars but has not been experimentally proven. They are starting experiments and discovering the first CNO neutrinos is a HUGE milestone in neutrinos research! This is the first and only experiment worldwide that is able to measure these different components individually while being quick and accurate.

Honestly, I don’t see a huge impact through this experiment or why it benefits us, but it’s a pretty interesting concept. Seeing how this may change the way scientists study the stars is strange to me. Why would we want to change what was already working? But, I did enjoy reading this article. It’s good to always be informed so that you can have opinions and not be clueless about all of the cool scientific experiments that are happening on a daily basis.

“Electric Nose” Can Pick out Multiple Scents

November 25, 2020 by heinitja · Chemistry

Isiah Warner, a chemist at Louisiana State University, has developed an “electric nose,” which is better at picking up hazardous scents than its predecessors. It does so by determining the mass of the molecules that cause odors. It was able to detect several smells at once, from freshly-peeled oranges to explosive vapors.

There are clearly many uses for a device such as this. For example, it could be used by security personnel to find potentially hazardous materials such as explosive vapors or dynamite. Also, It would easily be able to pick up gas leaks, or hazardous gasses.

ICYMI: COVID-19 Linked to Blood Clots and Strokes

Scientist have found that a large number of covid patience have blood clots. patience with covid and those in the intensive care unit overall thirty one percent of them have clots. The clotting can greatly increase their chances of death especially if the clotting is found in their arteries, it may also result in surgical amputations. Using proactive medication and being hospitalized may reduce the cause of clotting.

I am quite interested in how they are planning on avoiding all the obstacles covid-19 has thrown at us. They are still continuing to learn about this new disease. This article is very informative about why they are finding these blood clots and how they found them. It is very specific and puts ease on the mind of the ignorant that they are working to fix everything that may affect the outcome of this disease. They inform you how exactly to treat the blood clots to avoid further damage.

Separating Co2 from Industrial Waste Gases

October 27, 2020 by sarwanc · General Science

Atmospheric carbon dioxide – a tale of two timescales | Energy Matters


As the fight against climate change rages on, chemists may have developed an effective and sustainable material that may be vital in dealing with industrial gas emissions. Essentially, this material is able to separate the greenhouse gas co2 from industrial waste gas, natural gas, and biogas allowing for the gas to be recycled. More importantly, this process can now be cost-effective and energy-efficient.

I found this rather exciting. For the longest time, it seemed that the solutions offered to help fight against harmful emissions were either far-fetched or just too costly or inefficient. Luckily now with the development of this complex new material, we are one step closer to winning the fight against global warming.
