The influence of coating-carbonization cycles toward P84 co-polyimide/nanocrystalline cellulose
Published 2019“…The PI/NCC SEM images showed that all the carbon membranes samples comprised of dense structure while the FTIR analysis exposes that existence of functional groups is decreased for all coating-carbonization-cycles samples. The XRD result shows that the membrane carbon structures are amorphous in nature. …”

Effects of microplastics on soil microorganisms and microbial functions in nutrients and carbon cycling – A review
Published 2024“…This paper critically reviews the effects of MPs on soil microbial diversity and functions in relation to nutrients and carbon cycling. Reports suggested that both plastisphere (MP-microbe consortium) and MP-contaminated soils had distinct and lower microbial diversity than that of non-contaminated soils. …”

Carbon cycling in Arctic lakes: sedimentary biomarker reconstructions from Disko Island, West Greenland
Published 2017“…A palaeolimnological study of three lakes on Disko Island, West Greenland was conducted across a hydrogeomorphic landscape gradient, to reconstruct principally changes in algal pigments, lipid biomarkers and carbon isotopes (δ13C) to investigate carbon cycling at multiple scales and resolutions. All three records reconstructed recent change on Disko, with records from lake Disko 2 additionally spanning since ~7640 cal. yr BP and lake Disko 4 since ~1260 cal. yr BP. …”

Environmental response to the early Toarcian carbon cycle and climate perturbations in the northeastern part of the West Tethys shelf
Published 2018“…Early Toarcian (Early Jurassic; ~183 Ma) climate and carbon cycle perturbations were accompanied by widespread accumulation of bituminous sediments, formed during the Toarcian Oceanic Anoxic Event (T-OAE). …”

Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China
Published 2017“…Since recycled sedimentary carbonate through plate subduction is the main light-d26Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling. Here, we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low d26Mg isotopic compositions, while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Pacific subduction zones have mantle-like or heavy Mg isotopic characteristics. …”

Changes in CO2 during ocean anoxic event 1d indicate similarities to other carbon cycle perturbations
Published 2018“…Past greenhouse intervals of the Mesozoic were repeatedly punctuated by Ocean Anoxic Events (OAEs), major perturbations to the global carbon cycle and abrupt climate changes that may serve as relevant analogs for Earth’s greenhouse gas-forced climate future. …”
