News on China's scientific and technological development.

Recently, the Chinese Academy of Sciences team has made a major breakthrough in the field of refrigeration materials research: the potassium hexafluorophosphate it discovered has become the world's first solid-state phase change material that can achieve refrigeration from room temperature to nearly absolute zero degrees.

Researchers from the Institute of Metal Research, Chinese Academy of Sciences, have discovered a new refrigeration material called potassium hexafluorophosphate. This material can achieve a cooling effect across a temperature range from room temperature to near absolute zero, making it the only solid-state phase change refrigeration material that operates effectively across the entire temperature spectrum to date. The relevant research findings have been published online in the journal Nature Communications. Previously, solid-state phase change refrigeration materials had a common limitation, functioning only within a very narrow range near the phase transition temperature. However, the 'full temperature range pressure card effect' was observed for the first time in potassium hexafluorophosphate, allowing this material to continuously achieve cooling over a wide temperature range from room temperature to liquid nitrogen, liquid hydrogen, and even liquid helium by applying pressure. This discovery opens up new avenues for the development of a new generation of efficient, environmentally friendly all-solid-state refrigeration technologies, and is expected to fundamentally revolutionize the design concepts of refrigeration devices such as refrigerators in the future

The profound advancement of digital transformation has fundamentally altered various sectors within urban environments, with road transportation being no exception. Digital technology is regarded as a key driver for achieving high quality development of road transportation (HQDRT) and building a leading transportation nation.However, existing research has not comprehensively elucidated the mechanisms through which the level of urban digital technology (UDTL) influences HQDRT, nor has it thoroughly explored the accompanying synergistic effects, especially within the context of the current revitalization strategy for Northeast China.

This study employs panel data from 12 prefecture-level cities in Heilongjiang Province spanning from 2011 to 2022, utilizing econometric methods and a coupling coordination model to rigorously analyze the dual effects of UDTL on HQDRT. Additionally, kernel density estimation and geographic detectors are applied to investigate the temporal and spatial heterogeneity of the synergistic evolution between these two factors and their underlying driving forces. The results indicate that UDTL possesses a positive influence on HQDRT across various prefecture-level cities in Heilongjiang, and a significant synergistic relationship is observed between these variables. Further analysis reveals pronounced regional disparities in their collaborative development, exhibiting a typical core-periphery structure. Core cities demonstrate substantial regional spillover effects through technological accumulation and institutional innovation, whereas peripheral cities confront challenges associated with delayed synergistic evolution.

Furthermore, the prefecture-level cities in Heilongjiang are gradually transitioning towards a multi-layered and multidimensional comprehensive development stage, as traditional single-factor driven models are increasingly inadequate to meet the complex collaborative development needs of UDTL and HQDRT. This research extends the boundaries of existing studies focused on the digital transformation of road transportation and provides valuable insights for promoting green and sustainable development within this sector.

Adopting agricultural green production technologies (AGPTs) is crucial for enhancing agricultural sustainability. This study draws on data from 1281 rice farmers in Jiangxi Province, China, surveyed in 2023. Using multivariate ordered probit models and mediated effects models, it examines whether cooperative membership affects the utilization of AGPTs. The findings reveal that the means of sample farmers’ adoption of AGPTs and cooperative membership are 0.764 and 0.234, respectively, indicating that the adoption rate of AGPTs and the cooperative participation rate among farmers are relatively low. Cooperative membership, along with services such as land transfer, agricultural input procurement, production technology, and product marketing, significantly promotes the use of AGPTs. Specifically, cooperative membership encourages the adoption of organic fertilizers, soil-formula fertilizers, water-fertilizer integration, and green pest control technologies. However, it has no significant influence on the uptake of water-saving irrigation technologies. The impact of cooperative membership is powerful among farmers with lower educational attainment and in villages with higher economic levels. Additionally, cooperative membership enhances the application of AGPTs by improving farmers’ environmental awareness, risk attitude, operational scale, and credit accessibility. Therefore, the government should encourage farmers to actively adopt AGPTs through measures such as supporting the development of cooperatives and improving the quality of their services.
