1月22日，记者从中国科学院金属研究所获悉，近日，该研究所李昺研究员团队与合作者在制冷技术领域取得新突破——首次发现"溶解压卡效应"，有望为 高耗能数据中心等算力基础设施提供低碳、高效的新型冷却解决方案。该研究成果1月22日在国际学术期刊《自然》发表。 基于"溶解压卡效应"，团队设计出一套四步循环系统：加压升温→向环境散热→卸压降温→输送冷量，单次循环可实现每克溶液吸收67焦耳热量，理论效率 高达77%，展现出优异的工程应用潜力。 该成果为下一代数据中心冷却技术提供了原创性方法，有望推动算力基础设施低碳运行。 "压卡效应"可以形象地理解为：就像用力挤压一块干燥的海绵，海绵内部结构被压紧时会发热；松开手后，海绵迅速回弹，会从周围吸收热量而变凉。这种 固态材料靠自身结构变化来制冷的方式，虽原理新颖，但传热慢、制冷量有限。而新发现的"溶解压卡效应"则相当于挤压一块吸满盐水的湿海绵——挤压时 盐水被挤出并放热，松开手时海绵重新吸回盐水，这一过程会强力、快速地吸收周围大量热量。它不仅制冷能力更强，还因为液体本身能流动传热，一举解 决了传统固态材料"造得出冷、却送不走热"的工程难题，为高效、紧凑的冷却系统开辟了全新可能。 ...

Core Viewpoint - The discovery and publication of a new species of Rhododendron, named "Mulun Rhododendron," by researchers from various institutions highlights the biodiversity of the Rhododendron genus in China and its potential ecological and economic significance [1][2][5]. Group 1: Discovery and Classification - The new species, Mulun Rhododendron, was identified and published in the international journal "Plant Taxonomy" by researchers from Guangxi Institute of Botany, Zhejiang Normal University, and other organizations [1]. - Morphologically, Mulun Rhododendron resembles Wuming Rhododendron but is distinguished by its hairless buds, petioles, and leaves, as well as its larger, funnel-shaped flower corolla that is white with a light pink hue [2]. Group 2: Conservation Status - The population of Mulun Rhododendron is critically low, with fewer than 250 mature individuals identified, and the largest subpopulation containing no more than 150 mature individuals, categorizing it as endangered (EN) according to the IUCN Red List [2]. Group 3: Biodiversity and Economic Importance - The Rhododendron genus is the most diverse within the Ericaceae family, with approximately 1,150 species globally, over 1,000 of which are found in the Northern Hemisphere, predominantly in China and the Malay Archipelago [5]. - China is home to around 600 species of Rhododendron, with more than 400 being endemic, particularly in the southern and southwestern regions where species diversity is highest [5]. - The discovery of Mulun Rhododendron adds to the diversity of the Rhododendron genus in China and emphasizes its importance as a unique genetic resource for karst ecological restoration and landscape development [5].
