The invention relates to a method of modifying pitch compositions to reduce puffing during high temperatures processing steps. In particular, the invention relates to a modified pitch composition including about 0.1 wt.% to about 50 wt.% carbon additive and about 15 wt.% to about 99 wt.% pitch, a method of stabilizing pitch to form a modified pitch composition comprising blending about 0.1 wt.% to about 50 wt.% carbon additive and about 15 wt.% to about 99 wt.% pitch to form the modified pitch composition, and a method of forming a carbon article including heating a modified pitch composition comprising about 0.1 wt.% to about 50 wt.% carbon additive, and, about 15 wt.% to about 99 wt.% pitch to a carbonization and/or a graphitization temperature to form the carbon article, to reduce puffing during high temperatures processing steps. In the examples, coke, carbon black, and carbon nanotubes were used as carbon additive, whereas the used pitch was developed from a highly aromatic refinery bottoms feedstock.

Systems and methods for improving color uniformity in image displays are disclosed. An illustrative display includes first and second emitters configured as subpixels of a same color, a data store storing different, per-emitter values, and a controller. The controller accesses these values to drive the first emitter with a first current to produce a first wavelength, and the second emitter with a second, different current to produce a second wavelength. The second current is selected such that a difference between the second and first wavelengths is less than a difference that would exist if the second emitter were driven with the first current. This amplitude-based color correction may be combined with pulse-width modulation (PWM) to control apparent brightness.

A recycling process for Lithium-ion (Li-ion) batteries employs a closely monitored co-precipitation reaction for precipitating cathode active material precursor (pCAM) in a comingled form of metal salts corresponding to the intended chemistry for the new battery. The coprecipitation relies on a controlled pH that assures a particle size, morphology and purity of the resulting precipitated pCAM. A combination of internal reactor pH sensing within the coprecipitation reactor along with external pH sensing to validate the sensed pH ensures a consistent target pH throughout the coprecipitation process, compensating for drift or sensor failure in view of the harsh reactor environment.
