GS Xiulin Ruan next to new paint The paint is capable of reflecting 98% of sunlight as well as ultraviolet (UV) rays through the atmosphere into the space. During the test, this paint makes the surface temperature 4.50C lower than ambient temperature, even in strong sunlight. It is expected that this paint can be available on the market in 1-2 years. Reflective white paints are now much better than dark roofing materials, but only reflect 80% -90% of sunlight and absorb UV. This means they cannot cool surfaces below ambient temperature. New coatings do this, resulting in fewer need for air conditioners and reduced air conditioning emissions. “Our paint can help fight global warming by helping to cool the earth, which is the coolest point,” said Professor Xiulin Ruan of the research group at Purdue University. According to Professor Xiulin Ruan, painting a roof with an area of ​​93 square meters will save 10kW of electricity consumption of the air conditioner. The substance playing an important role in this new paint is barium sulphate. Unlike conventional titanium dioxide pigments, it does not absorb UV rays. This super white paint uses standard acrylic solvents and can be manufactured like conventional paints, the researchers said. The new paint will cost the same as today’s paints, they added, because barium sulfate is actually cheaper than titanium dioxide. However, it is necessary to evaluate the durability of this paint for a longer time.

Indianapolis Star Daily quoted a police source announced at 23:30 on April 15 (US time), or around noon April 16 (in Vietnam time), saying many victims were discovered. FedEx international carrier office at 8951 Mirabel Rd, Indianapolis City, Indiana, USA.

This is the latest shooting to take place in America. At the end of March 2021, a shooting in an office building in Southern California claimed the lives of four people, including a child. On March 22, 10 people were killed in the shooting at a vegetable shop in the city of Boulder, Colorado.

Each year, the US records nearly 40,000 people killed in gun-related cases, and more than half of them are suicidal.

Other people were taken to hospital to treat the injuries, police said.

Indianapolis Police Department spokesman Genae Cook said police immediately arrived at the scene after receiving notification of the shooting at 23:00.

“Eight people died from bullets”, Ms. Cook said. This figure does not include gunmen.

According to Cook, it is too early to know if the gunman is an employee of the facility. His motives are also unknown. An investigation is underway.

In a statement, FedEx said: “Safety is our top priority. We are working to gather more information and are working with investigating agencies.”

The base of the shooting had more than 4,000 people working.

An unnamed witness told local media he heard gunshots while working and looked up to see the villain. As he bent down, he heard more gunshots.

This person then ran out of the building and saw another collapsed on the ground.

A series of shootings have occurred in the US in recent weeks.

In early April, President Biden announced a series of executive orders aimed at curbing gun violence.

“Gun violence in this country is an epidemic and a shame to the world. For God’s sake this must stop”, Mr. Biden stressed.

According to Biden’s new decrees, the US Justice Department will increase sweepstakes to reduce the increase in “ghost guns” and support states to pass “red flag law” that controls the identity of gun owners.
