创新背景

近年来对于微藻的研究不断发展，各项研究证明微藻对于很多科技行业都有积极作用，将微藻研究成果运用到核废料处理方式对于双方或许都会有光明前景。

创新过程

2022年4月，《通讯·地球与环境》杂志发表了一篇古生物学论文，美国堪萨斯大学研究人员在法国普罗旺斯艾克斯一个古代湖床的沉积物中发现2250万年前的蜘蛛化石进行研究，发现蜘蛛化石至今仍旧保存完好或许要是因为硅藻的分泌物。

研究使用高分辨显微镜技术发现蜘蛛被硅藻微化石环绕着。硅藻是囊泡藻界硅藻门单细胞植物，常由几个或很多细胞个体连结成各式各样的群体，有坚固多孔的细胞壁。硅藻死后，它们的细胞壁会沉于水底，经过亿万年的积累和地质变迁成为硅藻土。硅藻土可制造过滤剂、隔热及隔音材料等，广泛用于工业领域。

硅藻会分泌富硫物质，形成藻垫。研究人员认为，富硫物质包绕在蜘蛛周围，促进了硫化作用，固定并保存蜘蛛脆弱的身躯。硅藻最早开始出现在大陆湖后的6600万年里，硫化作用保护化石的过程可能非常普遍，将湖泊沉积物中的众多化石保存异常完好。

核废料最常用的处理方式是深度挖坑永久填埋，对外层封存材料要求极高。微藻分泌物可以在数千万年时间内完好保存化石，科学家或许可以在已有的封存材料基础上挖掘有效的微藻分泌物，研究其保存的原理核延展方式，人工合成类似的无害绿色可再生物质，为核废料封存材料进行创造开发。

甚至可以进一步研发土地深处自然产生的物质，利用已有物质核自然形成的物质相互作用，研究相关的物质形成，在人工基础上借助自然本身的力量对核废料进行安全的永久封存甚至直接减弱放射性消除其存在。

创新关键点

研究微藻分泌物以及其他自然形成物质，挖掘其对核废料封存处理的可能性影响。

Microalgae secretions are possible to preserve nuclear waste

In April 2022, the journal "Communications Earth and Environment" published a paleontology paper. University of Kansas researchers studied 22.5 million-year-old spider fossils found in the sediments of an ancient lakebed in Aix-en-Provence, France. , found that the spider fossils are still well preserved, perhaps because of the secretions of diatoms.
Using high-resolution microscopy, the study found the spiders were surrounded by diatom microfossils. Diatoms are single-celled plants in the phylum Diatoms of the vesicular algae kingdom, often connected by several or many individual cells into various groups, with strong and porous cell walls. After diatoms die, their cell walls sink to the bottom of the water and become diatomite after hundreds of millions of years of accumulation and geological changes. Diatomaceous earth can be used in the manufacture of filters, heat and sound insulation materials, etc., and is widely used in industrial fields.
Diatoms secrete sulfur-rich substances to form algal mats. The researchers believe that the sulfur-rich material that surrounds the spider promotes vulcanization, which immobilizes and preserves the spider's fragile body. 66 million years after diatoms first started appearing in continental lakes, the process of sulfidation protecting fossils may have been widespread, leaving many fossils in lake sediments exceptionally well-preserved.
The most common treatment method for nuclear waste is deep digging and permanent landfill, which requires extremely high storage materials for the outer layer. Microalgal secretions can preserve fossils well for tens of millions of years. Scientists may be able to excavate effective microalgal secretions on the basis of existing storage materials, study the principle of preservation and nuclear extension methods, and artificially synthesize similar harmless ones. Green and renewable materials, create and develop materials for nuclear waste storage.
It is even possible to further develop substances naturally produced in the depths of the land, use the natural interaction of existing substances and cores to study the formation of related substances, and use the power of nature itself to safely and permanently store nuclear waste on an artificial basis, or even directly weaken it. Radioactivity eliminates its presence.
