Carbon isotope anomaly in the major plant C-1 pool and its global biogeochemical implications [PDF]

, 2004
We report that the most abundant C-1 units of terrestrial plants, the methoxyl groups of pectin and lignin, have a unique carbon isotope signature exceptionally depleted in C-13.

Spatial demand forecasting based on smart meter data for improving local energy self‐sufficiency in smart cities

IET Smart Cities, 2021
The use of distributed energy resources (DERs) in a city contributes to the net zero CO2 of a city. However, the spatially uneven distribution of power demand and surplus electricity causes congestion in the grid system, making wide‐area operation ...

Physical properties enhancement of carbon fiber obtained from isotropic pitch doped by ultra-long carbon nanotubes

Carbon Trends, 2022
Carbon fibers (CF) were formed from carbon nanotube-doped isotropic petroleum pitch. Ultra-long (the length of a single filament is more than 10,000 nm) double-walled carbon nanotubes (DWCNT) were used for doping in concentrations from 0.1 to 1.0 wt ...

Gas decomposition and electrode degradation characteristics of a 20% C3F7CN and 80% CO2 gas mixture for high voltage accelerators

High Voltage, 2021
Sulphur hexafluoride (SF6) is a potent greenhouse gas used in high voltage accelerators. As a promising alternative to SF6, the C3F7CN/CO2 gas mixture and its by‐products are of great interest to ensure the safe operation of accelerators that will adopt ...
