Given for this andsubsequentreactions are the energy released (Q) in millions of electron volts (MeV) and the half-life (t1⁄2). It should be noted that in alpha decays the charges, or number of protons, shown in subscript are in balance on both sides of the arrow, as are the ato...
The half-life (t1/2 = ln2/λ) and true mean life (tmean = λ/λ) of 14C are equivalent to 5730 and 8267 years, respectively (Stuiver and Polach, 1977). The usefulness of 14C as a dating tool depends on the detection limits of accelerator mass spectrometry, which usually ranges ...
However, half that capacity is being split between consumer electronics, larger vehicles such as electric buses and home or grid energy storage. In the 2030 world of 80 kWh battery packs and production of at least 35 million vehicles, nearly 3 TWh of battery manufacturing capacity will be ...
Natural fiber composites have a carbon footprint of around half that of glass fiber composites, including processing steps (Fig. 11). Joshi et al. [147] and Broeren et al. [151] analyzed the life cycle assessment of natural fibers over glass fibers. Their study stated that natural fiber ...
Model results revealed that pulses of carbon-rich dense water leave the shelf during and following the productive season in the second half of every year (Fig. 4).Fig. 4: Time series of cross-sectional transport of water masses and organic carbon from the FESOM–REcoM2 model run.a...

In a case study of the tech sector, we find that corporate reports omit half of the total emissions. The framework we present may help companies, investors, and policy makers to identify and close the gaps in corporate carbon footprints....
All the World’s Carbon Emissions in One Chart Two degrees Celsius may not seem like much, but on our planet, it could be the difference between thriving life and a disastrous climate. Over two centuries of burning fossil fuels have added up, and global decision-makers and business leaders ...
Moreover, 100% of participants responded to Question 2, “Do you believe your choices/initiatives have rather temporary or constant character? If possible, please indicate the timeline”, that at least half of their choices are intended to have the character of a constant change, while other ...
Intergovernmental Panel on Climate Change (IPCC) has published a report on climate change that includes carbon data obtained from previous literature and data collection using half-life of wood product to estimate the average decay rate. Moreover, chapter HWP in 2006 IPCC Guidelines for National Gre...
