Bio-composite of nipa palm husk derived activated carbon/poly(butylene succinate): an effective agricultural waste based adsorbent for ammonia removal

Autor: Chaichana PIYAMAWADEE, Viboon SRICHAROENCHAIKUL, Duangdao AHT-ONG

Publikováno v: Journal of Metals, Materials and Minerals. 32:27-40

In this work, activated materials were successfully prepared by pyrolyzing various ratios of Nipa palm husk powder to potassium hydroxide (1:1, 1:2, and 1:3) at predetermined temperatures (500℃, 600℃, and 700℃). The surface area was obtained fr

The Influence of Amount of Succinic Anhydride in Chain Extension Reaction on Increasing Molecular Weight of Poly(lactic acid)

Autor: Duang Dao Aht-Ong, Chaichana Piyamawadee

Publikováno v: Advanced Materials Research. 747:148-152

High molecular weight PLA was successfully synthesized by chain extension reaction of hydroxylated prepolymer using succinic anhydride as a chain extender. Hydroxylated prepolymer was prepared by direct condensation polymerization of L-lactic acid in

Exogenous spermidine alleviates UV-induced growth inhibition of Synechocystis sp. PCC 6803 via reduction of hydrogen peroxide and malonaldehyde levels

Autor: Saowarath Jantaro, Orawan Sodsuay, Chaichana Piyamawadee, Aran Incharoensakdi, Wipawee Baebprasert

Publikováno v: Applied biochemistry and biotechnology. 173(5)

Effects of exogenously added spermidine (Spd) to UV-treated Synechocystis sp. PCC 6803 cultures on their growth, intracellular pigments, hydrogen peroxide (H2O2), malonaldehyde (MDA) contents, and antioxidant enzymes were investigated. Growth inhibit
