Synthesis and Application of Conductive Pitch‐Based Porous Carbon for Energy Storage Device as a Supercapacitor

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Eco‐Friendly Aqueous Polymeric Binders for High‐Performance Graphite Anodes: Structure–Property Insights for Lithium‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.

Synthesis and Interfacial Behavior of Mixed Potassium N‐Lauroyl/N‐Myristoyl Glycinate Surfactants With Varying Alkyl Chain Ratios

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biodegradable and low‐irritant amino acid–based surfactants have attracted considerable attention as environmentally friendly alternatives to conventional petroleum‐derived surfactants. In this study, a series of acyl amino acid surfactants with identical amino acid head groups but different alkyl chain lengths were synthesized via a modified ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, EarlyView.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.
