Efficient and Low-Carbon Synthesis of Colorless Transparent Polyimides The widespread use of polyimide varnish in semiconductors, packaging, and flexible displays has created increasing demand for efficient and environmentally friendly preparation. Compared to polyamic acid varnish, polyimide varnish offers enhanced stability and significantly improved process control, as it eliminates the need for chemical reactions during subsequent production steps.

ABSTRACT The purpose of the present study was to explore whether maximum efficacy treatments would be dependent on the time of day at which antidepressants were taken. Databases were searched for randomized experiments or randomized controlled trials involving interventions of any antidepressants taken at a particular time of the day. Out of 10 348 screened articles, 10 studies were included in the meta-analyses.

Innocuous solvent-based, low-temperature curable, and high transparency photosensitive polyimides developed by soluble polyimides containing bio-based magnolol moieties Traditional photosensitive polyimide (PSPI) materials require a high curing temperature and exhibit low transparency, limiting their applications in thermally sensitive optical devices. To overcome this challenge, soluble photosensitive polyimide resins were synthesized based on the structural design of bio-based magnolol monomer.
