Advanced Science, EarlyView.Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

High brightness mechanical pulps.
JAPAN TAPPI JOURNAL, 1990 Mechanical pulps are traditionally bleached by either hydrosulfite or peroxide. Market demands for high brightness mechanical pulps have prompted consideration of alternative bleaching processes to achieve higher brightness in a cost effective manner. Most commonly, these processes utilize reductive (sodium hydrosulfite [Y], sodium borohydride [R] as ...
