Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.
According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.
Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.
The supply and prices of many other 3D printing metal powder are expected to continue to be influenced by international situations.
Scientists at Skoltech University in Russia used a 3D printer to create an alloy of two materials whose composition ratios varied from one region of the sample to the next, and the resulting alloy had gradient magnetism, even though none of the initial materials were magnetic.
3D printing, a rapid prototyping method, is maturing for aircraft parts, medical implants and prosthetics, jewelry, custom shoes, and more.
The main advantage of 3D printing is the ability to create objects with very complex shapes that are either too expensive to produce or completely impossible to produce using traditional casting, rolling, stamping, or machining methods. 3D printing speeds up prototyping time and offers greater flexibility in product personalization and the number of batches. Another significant advantage of 3D printing is its low waste.
However, 3D printing has its limitations, requiring objects to be made entirely of homogeneous materials or mixtures. If the composition is different in different parts of the product, it is possible to obtain samples with changing characteristics. For example, A bar made of an alloy of two metals has A variable ratio of composition: one end starts with 100 percent of metal A, then 50 percent of each, then 100 percent of metal B, and so on. Thus, the properties of the obtained materials (including magnetic materials) can vary in a gradient, which makes them potentially useful for the manufacture of motor rotors, magnetic encoder strips, transformers, etc.
Skoltech scientists have researched and made such a kind of material, with the original ingredients A and B being two alloys: aluminum-bronze (copper, aluminum, and iron) and austenitic stainless steel (iron, chromium, and nickel, among others). Both alloys are paramagnetic, which means they are not attracted by magnets. But if you mix them, you get what's called a "soft magnetic material" ferromagnet, which is attracted to a permanent magnet.
The researchers used the two paramagnetic materials to create a gradient alloy. They used an InssTekMX-1000 3D printer, which works by depositing material using directional energy action, feeding a powdery material, and melting it with a laser at the same time. The resulting materials exhibit varying degrees of ferromagnetic properties, depending on the proportions of the components.
The researchers also theorized that the atomic structure of the alloy contributes to the expression of ferromagnetism in the alloy: although both materials have so-called face-centered cubic crystal structures, the combination results in a magnetic body-centered cubic structure.
Gradient soft magnetic alloys can be used in mechanical engineering, for example, in the production of electric motors. The results also show that the method of surface treatment of materials using directional energy action can not only obtain gradient materials using 3D printing but also discover new alloys. The technology is efficient and suitable for the rapid production of large parts.

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.
Matviyenko also noted that Europe currently lacks politicians who can make independent decisions. She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.
On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security.
Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain 3D printing metal powder are expected to continue to be influenced by international situations.
