As photosynthesis favours the lighter isotope, carbon 12, over the heavier carbon 13, this «light» ratio finding suggests that organic material from biological sources may have been more abundant in diamond - forming zones early in the Earth's history than we find today,» explained Suzette Timmerman, lead author on the study.

In the new study, researchers combined a naturally abundant raw material, sodium alginate (a polysaccharide that can be extracted from seaweed and algae) with a high - volume industrial by - product, silica fume (a by - product of ferrosilicon or silicon metal alloy processing) to produce a «green» adsorbent that is better than activated carbon.

Carbon dioxide, that is, the aerial form of the carbon of which we have up till now spoken: this gas which constitutes the raw material of life, the permanent store upon which all that grows draws, and the ultimate destiny of all flesh, is not one of the principal components of air but rather a ridiculous remnant, an «impurity», thirty times less abundant than argon, which nobody even notices.
