Pre-diabetic insulin resistance is associated with sub-clinical inflammation and concomitant increase in systemic C-reactive protein(CRP)*** 2 diabetes mellitus(t2DM)patients register even higher chronic levels of inflammation,with excess circulating CRP originating from both typical hepatic synthesis,and also visceral white adipose tissue.

In June 2024,startup company Equatic(Santa Monica,CA,USA)announced that it had begun engineering work on the world’s largest and first commercial scale facility using the ocean to remove CO_(2) from the atmosphere[1].the company claims its plant at a yet-to-be determined site in Quebec,Canada,will be operational by 2027,sequestering 300 t of CO_(2) per day at full *** is already building a similar,but smaller,facility called Equatic-1 in Singapore(Fig.1)[2].that project,expected to be completed in 2025,will have the capacity to remove 10 t of CO_(2) per day.

Engineering copper sulfide-based heterostructures via cation exchange(CE)is an appealing approach,as it allows selective combination of distinct compositions and functions of metal *** heterostructures can play a significant role in photoelectrochemical applications,but the effect of the ratio between two or more domains in such heterostructures on the photoresponse has not been well explored.
