In order to further expand the world of inventions, the stars full of innovation shone in 2023, because this year also the race of knowledge and wisdom, discoveries and inventions continued very fast around the world. Research, inventions are the basis of the development of every country. There are elements. Without them, it is difficult to move the country on the path of development, although various experts and scientists have presented many inventions and discoveries in 2023.

Last year, experts developed carbon-dioxide absorbing wood, air pollution measuring device, bacteria-killing foam, a flying camera that can be stored in a jeep and many more. If it is said that these inventions can change the map of any country. It won’t be wrong if they play an important role. What else happened in the world of technology in 2023, you will get an idea of ​​it by reading the review report of inventions.

Power bank and security camera together

In 2023, a private company invented a powerful power bank with a 1080 resolution camera that can be used for home security. The most important thing is that the power of this power bank is 22000 mAh. and the output is 197 watts. It has a sound record and a high-resolution video camera with night vision that can stream video and audio directly to your phone.

Internally there is 64GB of local storage while it can also note slight movement on the front. Despite having so many features, it is very light in weight and easily fits in the hands. Wherever the camera is facing, it shows a 135-degree view and broadcasts it to your smart app. It can be placed in home security, child protection and car etc. Its feature is that it does not need any extra wire to use. The power bank can charge mobile phones about 70 times.

Carbon dioxide absorbing engineered wood

Last year, experts from Rice University have developed a sustainable and environmentally friendly material for building. This wood will not only be useful for the house and building, but will also absorb CO2. In fact, they are made of ‘Metal Organic Frameworks (MOFS)’. For this, the underlying structure of the wood is removed.

Wood is generally made up of three materials: cellulose, hemicellulose, and lignin. After extracting the lignin, MOF was added to it. When it was added to wood, it surprisingly became stronger than ordinary wood and it also began to absorb carbon dioxide from the air. Thus, engineered wood not only became stronger than before, but also absorbed carbon. It has also become an environmentally friendly product.

A black hole 30 billion times the size of the Sun has been discovered

Last year, British astronomers discovered a black hole 30 billion times the mass of the Sun, the largest black hole ever discovered. It is 8,000 times larger than Sagittarius A at the center of our Milky Way Galaxy. The discovery is made possible by the phenomenon of gravitational lensing and is the first time that a black hole has been discovered using this technique.

Gravitational lensing occurs when a galaxy in front bends and magnifies light from distant objects behind it. Using this technique, Durham University researchers took a closer look at the supermassive black hole at the center of the galaxy, hundreds of millions of light-years from Earth.

The brightest space explosion two billion light years away

In 2023, the brightest explosion occurred two billion light-years away from Earth. This resulted in the release of extremely intense radiation that enveloped the entire solar system and affected the instruments installed in several spacecraft. Gamma rays Such explosions are known as the most powerful and brightest explosions in the universe.

This burst has been named GRB 221009A. Analysis of 7,000 gamma-ray bursts revealed that GRB 221009A was the brightest burst ever observed. His teasing continued for a few seconds. During this period, several times more energy was released than our Sun.

Oil-absorbing and bacteria-killing foam

Last year, scientists at the University of Georgia developed a foam that can absorb oil from the environment on the one hand, and on the other hand, it can also absorb bacteria during medical equipment and operations. It has been named “Superfoam”. The phone is three-dimensional and crafted from polydimethylsiloxane (PDMS) fabric.

It is coated with small particles of graphene, while copper filings are placed which are effective in removing germs. Interestingly, the foam absorbs other contaminated liquids like chloroform, hydrochloric acid and other harmful contaminants, then the copper nanoparticles make it completely sterile.

A salt that distills carbon dioxide

Last year, to distill carbon dioxide, scientists developed a salt that can store ribbons of carbon dioxide at ambient pressure and temperature using minimal energy. This method could change the way industry distills, transports, and stores this greenhouse gas. Liquid gonidinium sulfate is electrically charged with carbon dioxide, in some cases single-crystalline gonidinium sulfate. A basic clathrate salt was formed, because the solution was covered with carbon dioxide without forming a strong bond.

A computer vision system that creates a luminous object camera

In 2023, experts developed a computer vision system that takes images from the reflection of bright and shiny objects placed in the room. The Massachusetts Institute of Technology (MIT) and Rice University have jointly created this computer vision system. In this way, a camera can be made out of anything that has a bit of shine, from metal to plastic. This system can turn even modestly reflective objects into digital sensors. In this way, imaging is also possible with side-absorbed and reflected light.

This computer vision can see every single angle and geometry and thus it all combines to form an image. A two-dimensional (3D) image of an object is placed in a multi-dimensional environment to create a three-dimensional image of it, and thus a photo can be taken only from the image. ‘Ka is named. First of all, the glowing object is photographed from several angles. The depth in the image is then measured. A computer algorithm then creates that image. Thus reflective surfaces can be turned into virtual sensors of the camera. Sides, corners and hidden corners can also be seen through computer vision systems.

A two-dimensional microchip

Dr. Mario Lanza and his colleagues from King Abdulaziz University of Science and Technology in Saudi Arabia have created the world’s first two-dimensional microchip in 2023. This chip performs high quality work at low power. The chip was made possible by the discovery of graphene, the thinnest layer of graphite, in 2004. Making it viable was also a challenge. Silicon-based ‘complementary metal oxide semiconductor’ (CMOS) circuits were first used as a basis.

He then prepared a six-dimensional (hexagonal) toady material from boron nitrate that was etched onto a very thin copper foil, then carefully placed on a CMOS circuit, electrodes were formed and the circuit was fabricated by photolithography. Thus cells were formed which consisted of a transistor and a memristor. The thickness of the two-dimensional boron nitrate layer was only 18 atoms or 6 nanometers. A current was passed through them which was controlled, then the Toddy chip was tested for a long period of time and it showed excellent performance.

A pocketable flying camera

In 2023, scientists developed a flying camera that can fit in a pocket. It weighs 125 grams and follows a pre-programmed path to capture great video. The fist-sized “Hover Camera X-One” takes three seconds to fly, so no moment can escape the camera’s eye. Five flight paths can be pre-programmed to give video footage a new twist, including overhead, pursuit, circling or orbit and hover options.

Thanks to its powerful camera, it captures stunning cinema-quality videos. Its special feature is that the drone camera is very easy to fly and control. In it’s hover position, it continuously stays in the same place and takes videos or selfies. On the other hand forward and backward, right and left its speed can be up to 20 km per hour. Its computer vision algorithm doesn’t let the camera stray from its course. It includes several stabilization features to keep it steady in high winds.

A lamp to eliminate air pollution in the room

Last year, experts from South Korea’s Yonsei University have developed a lamp shade to keep indoor air clean, which cleans the air in the room from pollution. Lamp shade coating made of titanium dioxide and platinum. Destroys harmful chemical vapors inside.

Although it is low in platinum content, it is rapidly depleted or converted to harmless components as household chemicals come in contact with it. The heat of the bulb plays an important role in this process. When the bulb heats up to 100 degrees Celsius, it converts the tail aldehyde gas (a common household pollutant) to acetic acid, producing a small amount of carbon dioxide in the process.

Hovering drone without electricity

Last year, South Korean scientists created a micro-drone that uses 150 degrees less energy than conventional drones, generates electricity from the wind, and can stay aloft for long periods of time. And so they cannot be made to fly for a long time. Under this reduction, the Korea Advanced Institute of Science and Technology has successfully tested it in an experimental wind tunnel.

Drones generate electricity from the air and stay in the air for a long time. It uses air waves to hover and is also an important innovation in energy saving. It works even with a slight breeze. It is named Micro Air Vehicle (MAV). Based on its sensors and algorithms, it notices the change in air waves and keeps changing its position. Thus it can fly successfully by consuming minimum energy. This drone (MAV) can be used for search and rescue, surveillance and continuous aerial surveillance of a place.

An experiment in generating electricity from dead bacteria

Last year, experts from the Federal Institute of Technology in Lausanne, Switzerland, conducted a successful experiment of generating electricity from dead E. coli bacteria. The team of scientists modified the bacteria, using a mechanism called extracellular electron transfer (EET), to make them highly efficient electrical microbes.

This process triples the production of electrical current compared to conventional methods. Although these unusual microbes that generate electricity naturally can only do so in the presence of specific chemistry. E. coli can grow in a variety of places, which means that electricity can be generated in a variety of environments, including wastewater.

Pacemaker charged by pulses

In 2023, scientists have created a pacemaker that can partially recharge its battery using heartbeats. The purpose of building it is to generate fresh electrical energy. The device can regenerate about 10 percent of the energy needed to trigger another heartbeat. In addition, this pacemaker also offers an extended battery life of 6 to 15 years compared to a conventional pacemaker. In this pacemaker, mechanical and electrical energy are linked together and can be exchanged back and forth, as Ultrasound converts electrical voltage into pressure or sound.

A device that keeps the mind active without the body

Last year, experts invented a device that can keep the mind alive and active without the body. With the help of computerized algorithms, the scientists maintained the blood pressure, volume, temperature and nutrient demand in the brain. According to the team of neurologists, despite receiving no biological intervention from the rest of the body, there was a very slight change in brain activity.

Scientists say the success of the experiment could open new avenues for studying the human brain without involving other functions of the body. While this technology has raised the hope of opening the way for brain transplant possibilities in the future. According to Professor of Neurology Juan Pascal, this new method makes it possible to conduct research that focuses on the brain independent of the body and answers all these biological questions like never before.
