Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics
FEBS Open Bio, EarlyView.Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Distributed energy efficient unequal clustering algorithm for wireless sensor networks
Tongxin xuebao, 2009 A distributed energy-efficient unequal clustering （DEEUC） algorithm was proposed for wireless sensor net-works by research current routing algorithms. The core of DEEUC has three parts. Firstly, when tentative clusterheads are selected, an average energy

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms
FEBS Open Bio, EarlyView.We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Countable connected-homogeneous digraphs [PDF]
, 2013 A digraph is connected-homogeneous if every isomorphism between two finite connected induced subdigraphs extends to an automorphism of the whole digraph.
