First Iranian Ice Protection System for Airplanes Unveiled
The first aircraft anti-icing system locally produced in Iran made by LAJVAR Industrial Group was unveiled during a ceremony in Arak, the capital of Markazi Province.
The system was produced by the company LAJVAR Industrial Group based in Arak at the order of the Ardabil Airport located in the city of Ardabil in the Northern part of Iran.
A number of officials from the Civil Aviation Organization of Iran and other officials were present in the unveiling ceremony of the system.
In the ceremony, Mir Saeed Safinia, the Director General of Airport Equipment and Systems of Iran Airports and Air Navigation Company (IAC) told reporters, “The total cost of the system was about 15 billion tomans while if we wanted to import it, it would cost the country more than 50 billion tomans.”
Moreover, Hamidreza Mahdinia, the CEO of LAJVAR Industrial said that the group with an experience of forty years is the first and largest manufacturer of hydraulic lifts, jacks, and cranes in the country. It has produced 57 product models and 5,500 lifts and cranes until today, he added.
“When the plane flies at a high altitude, it freezes, but now LAJVAR has designed a device so that the planes will not face that problem anymore. The design and making of this device took two years due to the high technology used in it and some of its hydraulic parts that were foreign-made and imported and difficult to get to us due to the sanctions,” the CEO further said.
Iranian Knowledge-Based Company Produces World’s Largest Burner
An Iranian knowledge-based factory produced the world’s burner and exported it to Russia.
Rouhollah Dehghani Firouzabadi, the Iranian Vice-President for Science, Technology and Knowledge-Based Economy visited the knowledge-based company of "Pakman" which is operating in the field of producing burners and industrial boilers.
The Pakman knowledge-based holding produces advanced knowledge-based products, including heating facilities and equipment and offers engineering services in the fields of heating, cooling, combustion and ignition, water treatment systems and industrial greenhouse facilities.
The products made by the Pakman company can compete with the products of prominent trademarks from countries with many years of experience in that field such as Germany.
One of the most important knowledge-based products made in the Iranian company is the largest one-piece burner in the world, which is specially designed for the Russian market and exported to that country.

Production of Antibacterial Polyester Yarn in Iran by Using Nanotechnology
Iranian technologists in textile industry succeeded in production of antibacterial nano polyester yarn.
Polyester fibers enjoy high strength, low water absorption and minimal water loss compared to other industrial fibers and are widely used in the clothing industry.
Polymeric materials can easily be contaminated by bacteria or fungi which leads to the transmission of diseases and severe infections. Preventing the contamination of the surface of these materials by microbes can be done by using an active antibacterial agent like nanoparticles in their structure.
According to the researchers of the company that has produced the antibacterial yarns, using silver nanoparticles in the yarn production process causes them to be trapped in the body of the yarn and creates antibacterial properties with good durability.
Iranian Researcher Invents 1st Drug to Treat Obstructive Sleep Apnea
A contract has been inked by an Iranian research team and a German-Turkish company to produce obstructive sleep apnea medicine for the first time in the world.
According to a report by the Public Relations Department of Birjand University of Medical Sciences in the Northeastern part of Iran, a contract was signed between Mohammed Mousavi Mirzaei, the inventor of a new medicine to treat obstructive sleep apnea and the German-Turkish company in the presence of the Iranian vice-president of the Center for Development and Development Cooperation.
The inventor of the world's first drug for obstructive sleep apnea who is the President of Birjand University of Medical Sciences said in that regard, “The exclusive owner of the company traveled to Iran several times in person to conduct negotiations and conclude the contract.”
“Due to the special nature and importance of this drug, many companies approached us for talks,” he added.
He further said that verification is very important in concluding such contracts, and the parties to the contract were keen to sign it.
Iranian Specialists Manufacture Semi-Chassis Flying Car with 280 km/h Speed
Iranian researchers succeeded in production of a semi-chassis flying car with the capability to drive 700 meters with a single charge and a maximum speed of 280 km/h.
“The car we designed is a combination of a multi-rotor and a normal car and any of these phases can be separated,” Mohammad Amin Farahmandfar, the project manager of Kandou team, told ANA.
He stated that the multi-rotor of the flying car can be used as a normal car, adding, “This project, a semi-chassis car with four-wheel drive was built and it has the ability to travel 700 meters with a single charge and a maximum speed of 280 km/h.”
“In the air phase, the flying car has high flight durability due to having a multi-rotor. The range of similar foreign samples is much weaker than the domestic sample. This plan can also be used in the military, aid and tourism fields. Its multi-rotor can also be used separately and on the ground,” Farahmandfar said.
Iranian Researchers Produce Smart Road Studs
Iranian researchers had designed and produced smart road studs which are capable of detecting animal and human movements, rock-fall and fire using microcontrollers and sensors.
Two Iranian researchers Aram Ghafouri and Shahram Ghafouri from the Western province of Kordestan won the silver medal of the International Exhibition of Inventions Geneva with the "Smart road studs" design.
The device was designed and produced to make the roads smarter to reduce road accidents and also to minimize the damage caused by road-related dangers for the environment.
“One of the technical problems on roads and streets that causes accidents is the lack of sufficient visibility for drivers due to factors such as fog, snow, rain, road bends, tunnels, high speed on highways, natural obstacles such as rocks, trees, humans, crossing wild and domestic animals. , fire, etc,” Aram Ghafouri told Iranian media about their invention.
“To resolve this challenge, we managed to design and produce a smart road stud with the capability to detect the situation in which the cars and the road are. This device is capable of detecting moving or stopped cars on the roads, as well as open or blocked roads due to rockfall or fire,” he added.
Study: Metaphors for Human Fertilization Evolving
In a common metaphor used to describe human fertilization, sperm cells are competitors racing to penetrate a passive egg, but as critics have noted, the description is also a 'fairy tale,' rooted in cultural beliefs about masculinity and femininity, a new study by sociologists said, adding, the study provides evidence that this metaphor remains widely used despite the profound shift in recent decades in social and scientific views about gender, sex, and sexuality.
A new study by Yale sociologist Rene Almeling provides evidence that this metaphor remains widely used despite the profound shift in recent decades in social and scientific views about gender, sex, and sexuality. But her findings, based on interviews with a diverse sample of 47 individuals, also reveal that a more gender-egalitarian metaphor is circulating that describes sperm and egg as two halves of a whole, the science daily reported.
"The metaphors we use in discussing biological processes like fertilization are powerful: They both reflect and produce collective understandings of our bodies, ourselves, and our society," said Almeling, a professor of sociology in Yale's Faculty of Arts and Sciences. "By studying biological metaphors, we can learn how they undergird our beliefs and actions."
The study, published Oct. 1 in the journal Gender & Society, was inspired by a landmark 1991 paper by the anthropologist Emily Martin, in which she made the case that scientists had relied on prevailing cultural beliefs of masculinity and femininity to construct "a scientific fairy tale" of active sperm penetrating a passive egg. Writing then, Martin demonstrated that the metaphor influenced the questions scientists studied and how they reported their findings in peer-reviewed journals or described fertilization in medical textbooks.
Iranian Firm Produces Stationery with Food Coloring, Wheat-Based Material
Iranian researchers at a knowledge-based company succeeded in production of a variety of stationery, including play dough made of food coloring and based on wheat flour.
“Our company makes 350 products. Since we are dealing with young children, we deemed it necessary to use materials that do not harm their health. Among the products of our company, we can mention gel rulers, food dishes, glasses and thermoses,” Fatemeh Saqafi, a representative of a knowledge-based company, told ANA.
“We have exported our stationery products to the neighboring countries and the Persian Gulf littoral states, including Afghanistan, Syria, Iraq, the UAE, Armenia, Tajikistan and Malaysia.”
Noting that the colors of the pencils designed in the company are edible colors, she said, “We also used Indonesian wood and plants in the tips of our pencils. The body of pens produced in our company is made of compressed plastic. Tests show that pens write 600 meters without interruption.”
Saqafi also referred to the production of play dough in the company based on water and wheat flour, saying that parents can return the dough to its original state and prevent it from spoiling by putting it in a wet cloth.
Iranian Scientists Produce Different Catalysts for Petrochemicals, Refineries
Iranian researchers at a knowledge-based company stationed at Ardebil Science and Technology Park obtained the technical know-how of producing several catalysts used in petrochemicals and refineries.
“Possessing advanced laboratory equipment to measure technical features, we make our products based on the standards required and approved by consumers and present them to major industries of Iran like oil, gas, petrochemicals, refineries, sugar and glucose plants, chemical plants, and drinking water treatment and industrial wastewater treatment companies,” said Mohammad Erfan Saqafi, the sales expert of the knowledge-based company.
He described production of catalyst-based graphite as one of the achievements of the knowledge-based company, and stated, “In most chemical industries like petrochemicals, refineries, acid production and other industries, the presence of graphite in the reaction medium is required and it increases the number and speed of reactions.”
“Active carbon is another product of our company which is used in refineries and petrochemical industries for gas sweetening and removing the smell of gas,” he added.
“Also, the researchers of our company have succeeded in producing a catalyst for application in car canisters. A piece of canister is mounted at the outlet of the car's gas tank and absorbs gas vapor,” Saqafi explained.
Iranian Company Produces Flame Retardants for Use in Different Industries
Researchers at one of the knowledge-based companies in Iran have not only produced bio-polymers for use in toys and food coatings, but also, they have produced flame retardant powders that make cables and construction equipment resistant in fire.
“Our company's products are PVC softeners,” Farhad Larki, director of research and development of the Iranian knowledge-based company said in an interview with Iranian media.
He added that their company has 30 years of experience in producing chemicals, including automotive and industrial antifreeze, PVC plasticizers such as TOTM, DOTP and DOS, Trimethylolpropane triacrylate (TMPTA) and powder products including flame retardant powder and special rubber improvers.
He added that some of these products are PVC-based oils that are used in the preparation of PVC granules and wire and cable industries, with plasticizers or softeners as examples, and stated, “Plasticizers are liquid substances that are mixed with hard polymers. And they make them soft and flexible to make them processable and create a variety of applications in them.”
“Plasticizers are substances injected into polymeric materials to provide or improve elasticity or plasticity required for reprocessing or use. They facilitate free-flowing material dispersion. Some of them, namely diketyl sebasate, also improve the properties of polymer materials against fire, light and heat,” he added.
Iran to Send Technology, Trade Delegation to Turkiye
The Center for International Science and Technology Interactions of the Iranian Vice-Presidency for Science, Technology and Knowledge-Based Economy is due to dispatch a trade and technology delegation of knowledge-based companies to Turkiye.

One of the indicators of the growth of science diplomacy is conducting joint research between two or more countries. Iran has written more than a third of its articles in Scopus in 2020 with international participation, which is about 30.7 percent.
Knowledge-Based Firm in Iran Makes Asphalt from Crumb Rubber
Iranian researchers at a knowledge-based company succeeded in producing asphalt by using waste materials like rubber crumb.
“We succeeded in producing permeable asphalt which is made of waste materials like crumb rubber that allows water to pass through its surface,” Alireza Haddadi, the managing-director of the knowledge-based company, told ANA.
“The asphalt is designed based on the type and capacity of the road and the available possibilities, and then the type of asphalt is ordered to the production plant,” he added.
Haddadi noted that permeable asphalts produced by using crumb rubber are very efficient in Northern regions of Iran due to heavy and continuous rainfall, adding, “Water does not remain on the asphalt surface and is directed to the sides of the road which increases the safety of the road surface.”
“Designing asphalt by using crumb rubber plays a highly important role in preserving natural resources and the environment,” he added.
Iranian Researchers Produce Drug to Treat Lymphoma Cancer
Iranian researchers at a technological company stationed at Pardis science and technology park succeeded in production of Ibrutinib pills for treatment of lymphoma cancer.
“In recent years, Ibrutinib tablets have been introduced as an alternative to unsuccessful treatment for patients with lymphoma, and this type of treatment is also used inside Iran,” said Sahar Bahmani, the managing director of the knowledge-based company.
“Since the medication was in Iran’s pharmaceutical portfolio as a single prescription and with high costs, our company started research to produce it in the country years ago, and produced Ibrutinib tablet after years of research,” she added.
Bahmani explained that the pill causes destruction and removal of cancer cells in the patient's body, adding that the drug has been marketed under the brand names of Broca 140 and Broca 420 and will meet the country’s needs.
