Researchers at the Chinese Academy of Sciences (CAS) have developed for the first time in the world a technology, which can produce glycol in ten thousand tons. CAS invited an expert committee
Zeolites have been widely used as catalysts in oil cracking and their structures and physico-chemical properties have been extensively studied. in recent years, many researchers also use zeolite-modified electrodes fo...

In the previous note, it has been shown that imbibitional chilling injury is a rather com mon phenomenon occurring during seed rehydration and may cause decline in seedling emergence or loss in crop yield. Its severit...
Hexamethoxymethylmelamine(HMMM) with polyols such as triethylene glycol (T3EG) can be cross-linked and cured by a special acid catalyzed transetherification, and multiacrylates, such as tetraethylene gl...

Imbibitional chilling injury is defined as a kind of chilling injury that occurs during seed imbibition. This is a prevalent problem associated with early planting in cold and wet soils, culminates in poor germination...
The synthesis and characterization of polysulfone (PSF)-polyester (PE) block copolymers were studied. Polysulfone-polyester block copolymers containing segments of PSF and PE (i.e. PPT, PBT, PHT, PDET, PTET) were synt...
There have been studies on the structure and properties of segmented polyetherurethane (SPEU)based on polytetramethylene glycol (PTMG)/4, 4′-diphenylmethane diisoeyanate (MDI)/1,4-butandiol (BD). It was shown that on...
This note is to report the exciplex formation between an excited state of the chromophore in poly (polytetramethylene ether glycol terephthalate) (PTMGT,
