Three Stage Bleaching of Recycled Fibers Containing 30% Groundwood [PDF]
, 1978 A three stage bleaching sequence for a mixture of recycled chemical and groundwood fibers was investigated for maximum brightness increase. The three stages consisted of a reducing or color stripping stage, an oxidizing stage, and last a mild alkaline ...

Advanced Science, EarlyView.Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Advanced Science, EarlyView.Biomass‐derived lignin is used as a sustainable precursor to synthesize Mo single atoms anchored on a nitrogen‐coordinated carbon framework. As the Mo structure transitions from MoC clusters to isolated single‐atom sites, oxygen evolution reaction (ORR) activity progressively improves.
