Optimisasi Produksi α-Amilase dari Saccharomycopsis fibuligera R64 dengan Response Surface Method-Central Composite Design (RSM-CCD)

Al-Kimia, 2019
α-Amilase (EC 3.2.1.1) is an endoamylase that hydrolyze α-1,4 glycosidic bond in amylose and amylopectin molecules yielding simpler carbohydrate. This enzyme is used to replace starch acid hydrolysis in industrial process. α-Amilase is used in many industrial processes including food, paper, bioethanol, and desizing in textile industries.

Metal‐Metal‐π Interaction: A Pathway to Construct Organic–Inorganic Excited‐State and Supramolecular Assembly

Advanced Optical Materials, EarlyView.
An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...
