The Chongqing International Logistics Hub Park, which includes the Tuanjiecun Station, the dry port of the New International Land-Sea Trade Corridor and the Chongqing Railway Port, has risen to be a major hub of international freight trains in the country’s western region.

China’s Chang’e-6 lunar probe aims to land in the historically rich Apollo Craters region on the far side of the moon. Giuseppe Reibaldi, president of the Moon Village Association, speaking with CGTN, identified several technological hurdles associated with the mission. Chief among these is establishing reliable communication with the spacecraft while it operates on the far side of the moon. The target landing region’s varied altitude changes and rugged terrain increase the difficulty of launching from the lunar surface. But the area is “important” to understand the moon’s evolution, he said. Check out the video to learn more!

A team of Chinese scientists has developed a high-strength aluminum alloy that remains operational even at 500 degrees Celsius.

This advancement has extended the service temperature range of aluminum alloys from 350 to over 400 degrees Celsius, addressing a long-standing engineering challenge.

The demands of the aerospace industry have set higher standards for thermal resistance in lightweight metal materials.

This innovative process is characterized by its simplicity, minimal material costs and scalability, making it highly valuable for industrial applications, said He Chunnian from Tianjin University, the corresponding author of the paper.

Although aluminum alloys are favored for their low density, high strength and robust corrosion resistance, their relatively low heat-resistance poses a considerable challenge, especially within the crucial temperature range of 350 to 500 degrees Celsius, which is pivotal for aerospace applications.

Researchers at Tianjin University synthesized aluminum alloys embedded with highly dispersive nanoparticles. The nanoparticles have grown in-situ graphene-like coatings, which significantly contribute to a reduction in surface energy.

Thanks to the incorporation of these nanoparticles, the alloys exhibit exceptional creep resistance at elevated temperatures of up to 500 degrees Celsius, according to the study published recently in the journal Nature Materials.

They also boast an impressive tensile strength of approximately 200 megapascals at that temperature, about six times higher than ordinary aluminum alloys.

During the recently concluded May Day holiday, museums remained a hot destination. Henan, known as a province rich in cultural relics, has unearthed countless national treasures. Among the 130,000 artifacts housed in the Henan Museum, a pair of radish and cabbage sculptures stood out as one of the museum’s top 10 treasures.

As soon as the museum opened its doors, visitors flocked straight to the exhibition hall, equipped with professional cameras, eager to capture their favorite star exhibits. What kind of radish and cabbage could withstand the test of centuries and still look so “fresh and tender?”

This is a pair of radish and cabbage carvings made of ivory during the Qianlong period of the Qing Dynasty (1644-1911). The ivory radish is about 27 centimeters long and weighs 229 grams. Its root gradually changes from red at the top to pink in the middle and white at the base, with naturally curved roots. The green leaves, with their main veins dyed red, exude a sense of movement as a grasshopper extends its front legs from the radish leaves toward the stem, eagerly seeking the sweet juice.

About 23 centimeters long and weighing 260 grams, the ivory cabbage shows layers of its white stem, green leaves, yellow heart and brown roots with clear veins. Two small flowers adorn the stem, one budding and the other in full bloom. A grasshopper rests on the back of the cabbage, blending seamlessly with the green leaves as it savors the fresh juice. Next to it lies a ladybug, its antennae barely visible, seemingly absorbed in its own feast.

The homophony of “cabbage” and “radish” in Chinese conveys the auspicious notions of continued prosperity and progress. In Chinese culture, grasshoppers symbolize family prosperity and longevity due to their strong reproductive abilities. So, the themes of “radish,” “cabbage,” and “grasshoppers” were common in art during the Ming (1368-1644) and Qing (1644-1911) dynasties, signifying auspiciousness through imagery.

These ivory radish and cabbage exhibits not only showcase the craftsmanship of ancient artisans but also reveals the profound symbolism of auspiciousness in traditional Chinese culture.
