Chitosan is a well-known excellent adsorbent for a number of organics and metal ions, but
its mechanical properties and specific gravity should be enhanced for practical operation. In …

Thermal and pH stabilities of free and immobilized α-amylase, β-amylase, and glucoamylase
were compared, in which immobilization support was prepared by equal weights of …

Equal weights of cuttlebone chitosan and activated clay were mixed and prepared as the
wet (without freeze-drying) and dried (with freeze-drying) beads. The resulting composite …

In order to improve the mechanical property of chitosan beads, the powder of loofah fiber
was added in chitosan/acetic acid slurry to prepare composite beads with and without freeze-…

This study determined antioxidant activity in terms of the 1,1-Diphenyl-2-picrylhydrazyl (DPPH)
scavenging ability and total phenolic content of black tea under different infusion and …

The development of efficient and robust catalysts based on earth‐abundant and nontoxic
materials is critical for the viability of the electrocatalytic conversion of CO 2 into useful …

This study investigated the polyphenol content, antioxidant activity, and inhibition ability of
mushroom tyrosinase and melanogenesis of Dendrobium tosaense (DT) extract. Ground DT …

In this study, the effects of different fruit parts and extraction conditions on the antioxidant
properties of jujube (Ziziphus jujuba Mill.) fruit were investigated. Five in vitro antioxidant …

The dried and wet chitosan–clay composite beads were prepared by mixing equal weights of
cuttlebone chitosan and activated clay and then spraying drop-wise through a syringe, with …

The stability of acid phosphatase immobilized on composite beads was studied. The beads
were prepared from equal weights of cuttlebone chitosan and activated clay and were cross-…
