The Nobel Prize in Chemistry is awarded to a scientist of Tunisian origin.. Who is Mengi Bounty?

American Lewis Bruce, Russian Alexey Ekimov and Tunisian-American Mengi Bounty have won the Nobel Prize in Chemistry, the Academy announced.

Who is Munji Bounty?

Al-Bounty is an American chemist of Tunisian descent. He was born in the French capital Paris in 1961. He spent his childhood in France and Tunisia before his father decided to immigrate to America.

He received a master’s degree in chemistry from Harvard University and a doctorate from the University of Chicago.

Focus on his business

Boundi’s research group focuses on studying colloidal semiconductor quantum dots, with increasing interest in organic fluorophores. Research projects generally fall into four categories:

  1. Spectroscopic analysis.
  2. Collection.
  3. Biology.
  4. devices.

Research initially focused only on the spectroscopic study of quantum dots, while recent progress has led to many challenges in synthesis, biological application of nanomaterials, and solar cell research. Additionally, the Bounty Foundation is interested in single quantum dot spectroscopy along with single molecule spectroscopy. Graduated from Harvard University.

His father is also a scientist

Mongi was the son of mathematician Mohamed Salah Bounty and Hélène Poupart.

In 1968, Muhammad Bawandi became an associate professor at the University of Tunis, then in 1970 he moved to France, where he worked briefly at the University of Nice-Sophia Antipolis, before moving to the United States in 1971.

Where does Monchi teach now?

Since spring 2008, El-Bounty has co-taught thermodynamics and kinetics with Professor Keith Nelson. Massachusetts Institute of Technology.

One of the original participants in the field of colloidal quantum dot research, Bounty is one of the most cited chemists of the past decade.

What is this year’s Nobel achievement?

The 2023 Nobel Prize in Chemistry rewards the discovery and development of quantum dots, nanoparticles whose size determines their properties. According to the Royal Swedish Academy of Sciences, these tiny elements of nanotechnology are used in the light emitted from televisions and LEDs, among others, to guide surgeons when removing tumor tissue.

The Swedish Academy, which awards the Nobel Prize, said: The 2023 Nobel Prize winners in chemistry have succeeded in creating particles small enough to have their properties determined by quantum phenomena. .”

The most dangerous of them is the “breath of the dead” … Bad breath is a symptom of these serious diseases

The most dangerous of them is the “breath of the dead” … Bad breath is a symptom of these serious diseases

Some metabolic disorders can cause bad breath due to various problems in the intestines, blood or liver.

The following are the most important medical conditions that can cause complications:

diabetes

  • A common condition that causes bad breath in the mouth and throat is diabetes because high glucose levels can cause the growth of harmful bacteria.
  • Because people with diabetes have insulin problems, cells may not get the glucose they need for energy, and instead the body starts burning fat-forming compounds called ketones.
  • Ketones accumulate in the blood and urine and cause bad breath.
  • One of these ketones is acetone, and it can cause breath to smell like nail polish.
  • If someone with diabetes notices the smell, they should seek medical advice as it could be due to diabetic ketoacidosis, a life-threatening condition.

Liver disease

  • If a person’s breath has a strong, foul smell, this is a sign that the liver is not filtering out toxins.
  • Doctors call this distinctive smell “the breath of the dead” because of its association with severe and fatal liver disease.

Kidney disease

  • Chronic kidney disease is a condition in which the kidneys are damaged and cannot filter the blood properly, which is why excess fluids and waste from the blood can build up in the body and cause other health problems such as heart disease and stroke.
  • People with kidney failure may develop bad breath.
  • As the kidneys begin to fail, the metabolic urea cannot be excreted effectively in the urine, and it accumulates in the blood and saliva.
  • The body converts urea into ammonia, which causes bitterness in the mouth and bad breath.
  • One in three people on dialysis say their breath smells like urine.

Too much methionine in the blood

  • It is an increase in a specific protein building block (amino acid) called methionine in the blood.
  • People with this condition often have no symptoms, but if their breath, sweat, or urine smells like boiled cabbage, they should see a doctor.
