Artificial intelligence has become a design force changing the main pillars of international order, such as sovereignty, legal independence, and the power distribution in the world. As algorithms infiltrate national security, economic policy, administration of people, war, they are undermining the premises on which the international law and the making of political choices has rested. The paper is a qualitative study, which discusses how artificial intelligence relates to the re-forming of authority, responsibility and influence in world politics. It claims that artificial intelligence undermines classical conceptions of territorial sovereignty, eliminates the monopoly of decision making by states, giving greater power to non-state structures and businesses, and intensifies competition on a strategic level. The analysis will be based on the latest literature, policy documents and legal debates to demonstrate that artificial intelligence makes accountability more complex and breaks the juridical systems as well as introduces the new sources of digital influence. The paper supplies that the international law governance should be developed to guarantee transparency, accountability, fair access to artificial intelligence facilities, and human control. Devoid of active reform, artificial intelligence may weaken international stability and increase inequalities, and establish new spheres of technological domination.

The synthesized nanocomposites slowly release fertilizer which can act as a high-efficiency NPK fertilizer formulation.

Recently, as an important class of mechanically active smart materials, thermoplastic dual-shape memory polymers (SMPs) have attracted notable attention and can be fabricated in many different manufacturing techniques.

The polar phase of PVDF nanowires was improved significantly with the modified AAO templates using a solution wetting method.

Novel architectures: growing petals on micro/nano fibers were fabricated via combining electrospinning with solvent-induced self-assembly.

An unsteady numerical simulation was carried out to evaluate the sliding surface temperature of polyoxymethylene (POM) for wear test. The numerical model consists of two-dimensional hollow circular cylindrical POM, metallic shaft, and ambient air. The effect of conductive and convective heat transfer on the sliding surface temperature was investigated. Simulation results are in a good agreement with experiments. The influence of sliding conditions on the sliding surface temperature and limiting PV value was also discussed. Moreover, ON-OFF operation was performed in order to consider actual sliding conditions.

Abstract Copper supported on SiO2, which was prepared from Cu(OCOCH3)2 and to which P was added, was a selective catalyst (80–85% at about 50% conversion) for the formation of HCHO by the dehydrogenation of CH3OH at 500 °C. Among various additives such as P, B, K, Li, Mo, and Zn, the addition of P to the Cu/SiO2 significantly enhanced the rate for the formation of HCHO with an increase in the selectivity.
