Opportunity charging of lead-acid traction batteries
IEC TS 61044:2021(E) covers opportunity charging of lead-acid traction batteries, i.e., the use of idle time during a working period to increase the state of charge (SoC) so as to extend the daily working period of a lead-acid traction battery while at the same time avoiding an excessive depth of discharge.
This document specifies requirements for the use of opportunity charging of lead-acid…
Nanotechnologies — Method to estimate cellular uptake of carbon nanomaterials using optical absorpti...
This document describes a near-infrared optical absorption method to estimate the in vitro cellular uptake of carbon nanomaterials including both internalized and/or tightly adhered to the cell membrane from liquid dispersions. This is a simple method to screen carbon nanomaterials uptake; additional analysis using a different technique can be required if quantification is desired.
