Electron Compensation Effect Suppressed Silver Ion Release and Contributed Safety of Au@Ag Core-Shell Nanoparticles
Au@Ag core-shell electron compensation safety biomedical application
2023/6/21
Silver nanoparticles (Ag NPs) have promising plasmonic properties, however, they are rarely used in biomedical applications because of their potent toxicity. Herein, an electron compensation effect fr...

ATLAS CMS 希格斯玻色子
2023/5/26
Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehen...
Bacteria release more carbon from the ocean than previously thought（图）
Bacteria release carbon ocean previously thought
2021/4/23
A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings ...
“连接过程”是云对地闪电的下行先导放电靠近地面时，诱发地面一个或多个物体产生上行先导放电，二者最终发生连接从而导致大电流回击的重要过程。其发生对于确定地面雷击目标物具有决定性作用，在雷电防护领域受到长期关注。然而，在雷电连接过程中，正、负先导之间发生击穿导通的“最后一跳”（Final Jump, or, Breakthrough Phase），持续时间仅微秒量级，探测相当困难，一直是雷电物理研究面...

近日，国际地学领域顶级期刊《Geology》刊发了中国地质大学资源学院陈红汉教授团队的研究成果——“Overpressure release: Fluid inclusion evidence for a new mechanism for the formation of heavy oil ”，该成果探讨了超压演化过程油组分和成熟度变化，证实古超压释放导致的极性组分析出是稠油形成的一种新机制，...
Small Arctic coastal waterbodies, with big carbon release（图）
Small Arctic coastal waterbodies carbon release
2020/6/5
Arctic coastal watersheds are some of the most threatened regions on Earth, having undergone substantial climatic, physical and biological changes with the warming of the Earth, scientists have found....
A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough methane—a potent greenhouse gas--to accelerate warming and cause catastrophe probably won't happen.
Ultra-fast communication allows aquatic cells to release toxins in unison（图）
Ultra-fast communication aquatic cells release toxins
2019/10/23
Crouching in the boot-sucking mud of the Baylands Nature Preserve in Palo Alto, bioengineer Manu Prakash of Stanford University peered through his Foldscope -- a $1.75 origami microscope of his own in...

Shocking Results Galaxy-Cluster Collisions
2017/11/23
A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a cel...
Image Release:New Radar Map Reveals The Moon’s Hidden Geology（图）
new radar map moon hidden geology
2017/9/5
As the public prepares for the upcoming eclipse, astronomers have released a striking new radar view of the Moon. Researchers from the Smithsonian’s National Air and Space Museum are using radio teles...
Tonga is a seismologists’ paradise, and not just because of the white-sand beaches. The subduction zone off the east coast of the archipelago racks up more intermediate-depth and deep earthquakes than...
Human-driven carbon release rate unprecedented in past 66 million years
Human-driven carbon release rate past 66 million years
2016/3/28
The earliest measurements of Earth's climate using thermometers and other tools start in the 1850s.To look further back in time, scientists investigate air bubbles trapped in ice cores, expanding the ...
Study:Alaskan boreal forest fires release more carbon than the trees can absorb
Alaskan boreal forest fires carbon trees
2015/11/12
A new analysis of fire activity in Alaska's Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the ...
