radiolysis

1 The action of radiation on materials is termed radiolysis.

辐射对材料的作用称作辐射分解。

2 Nicotine has been studied for the first time by pulse radiolysis techniques.

3 A second mechanism, radiolysis, may generate the rest.

4 Now a study published in Astrobiology contends that radiolysis could have powered microbial life in the Martian subsurface.

5 Extrapolating these rates over geologically important periods of time and merging with modeled radiolysis data yields a predicted 1000-fold decrease in 100–atomic mass unit organic molecules in ∼650 million years.

6 The researchers report that if water was present, radiolysis in the Martian subsurface could have sustained microbial communities for billions of years—and perhaps still could today.

7 Scientists have previously studied Mars radiolysis, but this marks the first estimate using Martian rocks to quantify the planet’s subsurface habitability.

8 It’s covered by the ancient Gawler Craton, and its iron and uranium mines point to the source rocks needed for both serpentinization and radiolysis.

9 They plugged these attributes into a computer model that simulated radiolysis to see how efficiently the process would have generated hydrogen gas and sulfates: chemical ingredients that can power the metabolism of underground bacteria.

10 This process, known as radiolysis, has sustained bacteria in isolated, water-filled cracks and rock pores on Earth for millions to billions of years.

11 Cassini's data show that molecular oxygen (O2) forms inside the moon's surface ice when water molecules (H2O) are split by energetic ions, a process known as radiolysis.

12 One example is radiolysis, in which subatomic particles naturally emitted by radioactive rocks such as granite cause certain molecules to break apart, releasing hydrogen.

13 Sherwood Lollar, Lin, Onstott and their collaborators proposed in 2006 that the microbial communities under South Africa and Canada derived the energy for their survival from hydrogen produced through radiolysis.

14 That process, water radiolysis, was first observed in Marie Curie’s laboratory at the beginning of the 20th century, when researchers realized that solutions of radium salts generated bubbles of hydrogen and oxygen.

15 So began their long quest to unpack how important radiolysis might be to life in natural settings.

16 Radiolysis could also help create food for these aliens.

19 With the surge in international cotton prices, cotton prices are also great radiolysis improve.

随着国际棉花价格的飙升, 纯棉布的价格也在大辐提高.
