A brief discussion on the categories and usability of lubricating oil antioxidants

To date, antioxidant products for lubricating oil have developed over nearly a century, forming specialized categories with distinct targeted functions. For example, in terms of chemical composition and structure, there are sulphur-based, phosphorus-based, nitrogen-based, amine-based, phenol-based, and phenol ester-based types. According to different mechanisms of action, they can primarily be classified as free radical terminators, peroxide decomposers, and metal deactivators, among others, and they can also be categorised based on the differences in their actual effects.

The Asian economy shows resilience amid tariffs and uncertainty

According to the latest article from the International Monetary Fund, despite facing multiple challenges such as high tariffs, weakened external demand, and policy uncertainty, Asian economies have shown resilience beyond expectations. This resilience is attributed to export-oriented strategies, technological investment, and policy support. To maintain strong and sustainable growth in the future, Asian countries urgently need to promote a transformation of their economic structures towards domestic demand and accelerate deepening regional integration.

Briefly describe the engine piston and its lubrication

The engine piston mainly consists of three parts: the piston crown, the piston head, and the piston skirt. The piston crown and the cylinder wall form the engine's combustion chamber, where the fuel-air mixture burns to push the piston downwards. The piston crown must endure high temperatures and pressures, with temperatures generally reaching 300-400°C and gas pressures up to 3-5 MPa for petrol engines and 6-9 MPa for diesel engines.

Between brittleness and toughness: the fog and path of the global economy in 2025

In this report, the International Monetary Fund raised its global economic growth forecast for 2025 to 3.0%, up from the 2.8% forecast in April, and expects further growth to 3.1% in 2026. This should be an encouraging indicator, but this 'report card' is inseparable from the short-term effects of a series of human interventions. The most critical variable is tariff policy. From July 27, China and the United States launched the third tariff negotiations in Stockholm, Sweden, and the two sides decided to extend the 'current suspension of tariffs' for another 90 days. Other economies such as Japan and South Korea reached a temporary easing agreement with the United States after tariff negotiations and postponed the deadline for further tax increases to August 1. This 'respite period' prompted enterprises and consumers to accelerate import and export operations, setting off a round of 'grabbing imports' effect, and promoting a brief jump in trade volume and enterprise investment. At the same time, the 'Big and Beautiful Act' passed by the United States has provided businesses with a large amount of tax incentives and fiscal spending, further stimulating economic growth. The strong rebound in U.S. stocks, the depreciation of the U.S. dollar, and the increase in capital inflows into emerging markets have collectively created an 'unexpectedly loose' financial environment, giving global markets signs of prosperity.
