For platinization of metals copper and brass objects are covered with a thin layer of platinum in the following solution, heated to a boil: 1 part ammonia platinum (ammonium chloroplatinate), 8 parts ammonia and 40 parts water. After platinization, the objects are cleaned with chalk. For the same purpose, objects can be rubbed with a mixture consisting of equal parts of ammonia platinum and cream of tartar.

Steel and iron objects can be platinized by coating them with a solution of chlorine platinum in ether.

For platinum small haberdashery items a solution of 10 parts of platinum chloride and 200 parts of table salt in 1000 parts of water, brought to a boil, can be used, to which a little caustic sodium is added to an alkaline reaction. In this solution, it is also possible to platinize with a zinc contact, i.e. bringing the metal surface into contact with the zinc rod.

Platinum iron

Copper sulfate 4,5 g;
Boron-lead salt 22 g.

Copper sulphate and boron-lead salt are mixed with turpentine until a porridge-like mass is obtained. A heated iron object is smeared with this mass and the worms wash it off for some time. Thus, a copper-lead layer is obtained on the object, on which, in turn, a layer of platinum is applied.

Mass for platinization is prepared from 10 g of platinum, converted into chlorine platinum. Chlorine platinum is mixed with 5 g of ether and left in the open air until all the ether has evaporated. Then mixed with 20 g of boron-lead salt, 11 g of red lead and a small amount of lavender oil until a porridge-like mass is obtained, to which 50 wt. including amyl alcohol.

Items intended for platinization are dipped into the prepared mixture, dried in air and heated. After heating and rinsing, they are coated with a platinum layer that can be polished.

Platinization of copper and brass items

Ammonium chloroplatinate 10 g;
Ammonium chloride 80 g;
Water 400 g.

The solution is heated to a boil in an enamel or glass container. Cleaned items are immersed in a hot solution, after which they are covered with a touch of platinum. Items are washed, dried and polished with chalk. Platinization of copper, brass, steel and iron.

Dissolve 10 g of platinum chloride, 100 g of table salt in 1 liter of water and add a few drops of 10% sodium hydroxide solution. The solution is heated to a boil and lowered into it (or placed on a zinc plate) cleaned objects, wrapped several times with wire.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Skyscrapers - solar farms 18.01.2022

The US company Ubiquitous Energy has received funding for a project to develop green windows that can provide buildings with green energy. The organization received $70 million from investors.

Ubiquitous Energy wants to do its part to save the planet from global warming through innovative green energy mining methods. So, to power skyscrapers, the company plans to cover the windows of urban buildings with an additional layer that can process solar energy into electricity. The thickness of such a layer is only a few nanometers, and small wires connect the entire system to electrical appliances.

According to company director Susan Stone, the money received will go to the final preparation of the product to enter the market. "In the future, we will be able to make French windows (windows to the floor). We will turn skyscrapers into vertical solar farms," Stone said. By early 2024, the organization plans to launch large-scale production. In addition to office buildings, Ubiquitous Energy also focuses on residential buildings.

New glasses have a minus - the price. Coated windows will cost 30 percent more than normal windows. However, the manufacturer and investors rely on the urgent need to solve the problem of global warming, hoping that this factor will increase demand for the product. As solar panels, Ubiquitous Energy windows also perform worse than traditional competitors - they are 50 percent less efficient. This is due to their position in space: less sunlight falls on a vertical surface than on a horizontal one.

“But we made a useful surface that did not generate energy at all. Glass was always passive, and we made it active,” Stone commented on the problem.

China has also made a bet on solar energy in the fight against climate change. The country's government is actively financing the construction of new plants for the production of polysilicon, a material used to make photovoltaic cells for solar panels. Thus, it is planned to reduce the cost of producing batteries and increase the pace of implementation of projects in the field of renewable energy sources.
