A two-stage catalytic degradation of polyethylene using amorphous silica−alumina and
HZSM-5 zeolite catalysts in series has been developed for converting the polymer into high-…

Abnormalities of the cornea and conjunctiva occur in association with neurological diseases,
nocturnal lagophthalmos, coma, infection, and mechanical ventilation. We investigated the …

The development of a new large‐scale purification protocol is required for research on the
reliable bioactivity and drug discovery of extracellular vesicles (EVs). To address this issue, …

For chemical recycling of waste plastics, HZSM-5, HY, and H-mordenite zeolites and silica−alumina
were examined as catalysts for the degradation of polyethylene in a fixed-bed flow …

and nine known cucurbitane-type triterpene glycosides, goyaglycosides-b,-c, and-d, and …

The saponin mixture from the seeds of the tea plant was found to exhibit an inhibitory effect
on gastric emptying and an accelerating effect on gastrointestinal transit in mice. …

The saponin fraction from the seeds of the tea plant, Camellia sinensis L. var. assamica
PIERRE cultivated in Sri Lanka, was found to show a potent protective effect on gastric mucosa] …

Photochromism of N-salicylideneanilines and related compounds was studied by measuring
the electronic and vibrational spectra of the transient species. The rise time of the transient …

Metal‐mediated base pairs formed by the coordination of metal ions to natural or artificial
bases impart unique chemical and physical properties to nucleic acids and have attracted …

The photochemical introduction of trifluoromethyl group with CF 3 Br in aromatic and
heteroaromatic rings was investigated for 9 compounds. Naphthalene, anthracene, anisole, N,N-…
