The team said the experimental vaccine had shown promise in a trial on mice.
It targets a condition known as atherosclerosis that causes a build-up of plaque – a deposit of fatty substances, cholesterol and cellular waste – in the arteries, which can lead to blood clots, stroke and heart attacks.
The nanovaccine was developed by a team of researchers from institutes including the Nanjing University of Science and Technology and the University of Science and Technology of China..."

NANJING, March 12 (Xinhua) -- In the latest step to clean energy technology, a Chinese company said that it has developed a prototype of ultra-longevity carbon-14 (C-14) nuclear battery, named Zhulong-1, making progress in the micro-nuclear battery innovation quest.
Wuxi Beita Pharmatech Co., Ltd. which is located in east China's Jiangsu Province, said it made the achievement in collaboration with Northwest Normal University in Gansu Province in the northwest of China.
Nuclear batteries convert radioactive decay energy into electricity, differing fundamentally from conventional chemical batteries. Wuxi Beita has established a whole C-14 industry chain system, covering C-14 labeling products and labeling technologies, laying foundation for developing Zhulong-1, according to the company.
Zhang Guanghui, technology leader of the battery project, who is from Northwest Normal University, told Xinhua on Wednesday that the core innovation of Zhulong-1 lies in the use of C-14, a radioactive isotope with a half-life of 5,730 years, which is paired with a silicon-carbide (SiC) semiconductor to generate power. As C-14 decays, it emits beta particles that interact with the semiconductor, producing a steady flow of electrons.
This approach addresses key technical challenges, including the preparation of high-specific-activity C-14 sources, and the low energy conversion efficiency and stability of transducer devices, said Zhang.
In a live demonstration at Wuxi Beita's laboratory, a Zhulong-1-powered LED has operated flawlessly for nearly four months, sustaining over 35,000 pulsed flashes. Researchers further validated its utility by integrating the battery with a Bluetooth chip -- which successfully transmitted and received wireless signals.
The research team named the battery after Zhulong, the mythical Chinese dragon deity symbolizing eternal light and energy in China's ancient text Shan Hai Jing, reflecting both the richness of Chinese culture and the battery's enduring energy supply characteristics, said Cai Dinglong, head of the battery project.
The battery can operate steadily within a temperature range of minus 100 degrees Celsius to 200 degrees Celsius, with an energy density 10 times higher than commercial lithium-ion batteries, and a degradation rate of less than 5 percent over a designed lifespan of 50 years, said Cai.
The Hefei Institutes of Physical Science under the Chinese Academy of Sciences conducted the battery tests.
Han Yuncheng, a researcher at the Institute of Nuclear Safety Technology, told Xinhua that tests indicate that Zhulong-1's core technological indicators -- including power levels, energy conversion efficiency, and stability -- are advanced.
As a new generation micro-power solution, C-14 nuclear batteries have a wide range of applications in healthcare, the Internet of Things sector and space exploration.
Notably, they can power permanent implants like brain-computer interfaces or cardiac pacemakers and support networks of trillions of sensors for the Internet of Things, Zhang said.
In addition, in extreme environments including the deep ocean, Antarctica, and on the moon and Mars, these batteries can serve as maintenance-free continuous power batteries -- while they can also enable interstellar spacecraft to operate consistently, added Zhang.
The research team is already advancing a second-generation model, Zhulong-2. Cai said that efforts will focus on reducing production costs and shrinking the size.
"Zhulong-2 is expected to be launched by the end of this year or early next year, measuring only the size of a coin," he said.

在中国神话传说和佛教故事中，哪吒“以莲藕重塑肉身”、为佛像“重塑金身”等说法广为流传，其关键在于材料选择。在现实世界，科学家们也执着于给材料“重塑金身”的探索研究，以期引领材料创新产业革命。
中国科学院物理研究所科研团队最近在这一领域取得重要突破，他们成功为金属“重塑金身”，实现厚度仅为一张普通A4纸百万分之一的单原子层金属，这项被誉为给金属打上“中国标签”、有望开创二维金属研究新领域的重要成果论文，以“埃米厚度极限二维金属的实现”(1埃米=100亿分之一米)为题，北京时间3月13日凌晨在国际知名学术期刊《自然》上线发表，审稿人认为“开创了二维金属这一重要研究领域”“代表二维材料研究领域的一个重大进展”。
首次实现大面积二维金属材料制备
论文共同通讯作者、中国科学院物理研究所张广宇研究员介绍说，二维材料近一个世纪以来被普遍认为不存在，但自2004年单层石墨烯发现以来(该研究2010年获得诺贝尔物理学奖)，二维材料极大颠覆了人类对材料的原有认知，并引领凝聚态物理、材料科学等领域的系列突破性进展，开创基础研究和技术创新的二维新纪元。
在过去20年中，二维材料家族迅速扩大，目前实验可获得的二维材料达数百种，理论预测近2000种。不过，这些二维材料局限在层状材料体系，其三维母体的原子层通过弱的范德华力相连，可通过机械剥离等方式来获得二维单层。纵观整个材料数据库，层状材料的占比非常小，97.5%以上的是非层状材料，如生活中随处可见的金属。
不同于层状材料(类似千层饼结构，很容易剥出完美一层)，金属由于每个原子在任意方向均和周围原子有强的金属键相互作用(类似压缩饼干)，要想将其重塑为原子极限厚度的二维金属，就好比从压缩饼干中剥出像千层饼那样完整的一层来一样而极具挑战性。
科研团队指出，二维材料可分为二维层状材料和二维非层状材料，以前的研究虽然发现很多二维材料，但基本局限在二维层状材料，而金属是非层状材料，这次研究在原子极限厚度下二维金属的实现超越当前二维层状材料体系，填补了二维材料家族的一大块拼图。
尽管过去实验中观察到一些非常薄的金属材料，但横向尺寸面积很小，一般小于100纳米，从纳米材料定义来看，这些材料应该算零维(而不是二维)材料。此外，以前制备的薄层金属和衬底有非常强的化学键相互作用，不能算严格意义上的本征二维金属。
本次研究是首次实现大面积二维金属材料的制备，也是首次实现环境稳定的二维金属，以前小尺寸的薄层金属非常不稳定，这次制备二维金属测试显示一年没有任何性能退化。
二维金属厚度仅A4纸百万分之一
在本项研究中，面对如何获得二维金属的挑战，张广宇带领团队发展了原子级制造的范德华挤压技术，通过将金属熔化并利用团队前期制备的高质量单层二硫化钼范德华压砧挤压，实现了原子极限厚度下各种二维金属的普适制备，包括铋、锡、铅、铟和镓。
这些二维金属的厚度仅仅是一张A4纸的百万分之一，也即一根头发丝直径的20万分之一。“如果把一块边长3米的金属块压成单原子层厚，将可以铺满整个北京市的地面。”张广宇形象阐释说。
范德华挤压制备的二维金属上下均被单层二硫化钼所封装，具有非常好的环境稳定性(在超1年的实验测试中无性能退化)和非成键的界面，有利于器件制备以探测二维金属的本征特性。
其电学测量表明，单层铋的室温电导率比块体铋的室温电导率高一个数量级以上，同时，单层铋展现出明显的P型电场效应，其电阻可被栅压调控达35%(块体金属通常小于1%)，为低功耗全金属晶体管和高频器件提供了新思路。此外，范德华挤压技术还能以原子精度控制二维金属的厚度(即单层、双层或三层)，为揭示以前难以企及的层依赖特性提供了可能。
有望推动人类文明下一阶段的发展
论文共同通讯作者、中国科学院物理研究所特聘研究员杜罗军指出，此次原子极限厚度二维金属的实现，不仅超越当前二维范德华层状材料体系，补充了二维材料家族的一大块拼图，还有望衍生出各种宏观量子现象，促进理论、实验和技术的进步。比如，二维金属既为材料理论研究提供一个理想的量子受限模型体系，也是实验探索量子霍尔效应、二维超流／超导、拓扑相变等的绝佳载体。
张广宇则认为，就像三维金属引领了人类文明的铜器、青铜和铁器时代，原子极限厚度的二维金属有望推动下一阶段人类文明的发展，带来超微型低功耗晶体管、高频器件、透明/柔性显示、超灵敏探测、极致高效催化等众多领域的技术革新与应用。
此外，范德华挤压技术为二维金属合金、非晶和其他二维非层状材料也开辟了有效原子级制造方案，为各种新兴的量子、电子和光子器件应用勾勒出美好愿景。
至于本次研究多次提及的专业术语范德华挤压，科研团队科普称，它和通俗理解的两个平面对顶挤压一样，只是采用的压砧为原子级平整且无悬挂键的范德华材料，这是实现二维金属的核心技巧之一。人们通俗理解的两个平面，比如玻璃，金刚石等，虽然看起来很平，但其原子尺度很粗糙，要制备二维金属，必须用原子级平整的材料来压。
同时，从目前实现的结果来看，范德华挤压能够通过调控参数原子级精准地控制二维金属的厚度，实现单层、双层、三层，可以算原子级制造。(完)
