A review of composite polymer-ceramic electrolytes for lithium batteries

open access: yes, 2021
All solid-state lithium batteries are garnering attention in both academia and industry. Lithium-ion conductive polymers and lithium-ion conductive ceramics are the two major classes of solid electrolytes that have prevalently been pursued for many years.

Modelling of cutting fibrous composite materials: current practice [PDF]

open access: yes, 2015
Using fibre reinforced polymers (FRP) is increasing across many industries. Although FRP are laid-up in the near-net shape, several cutting operations are necessary to meet quality and dimensional requirements.

Evolution of composition filters to event composition

open access: yesProceedings of the 27th Annual ACM Symposium on Applied Computing, 2012
Various different aspect-oriented (AO) languages are intro- duced in the literature, and naturally are evolved due to the research activities and the experiences gained in applying them to various domains. Achieving modularity, compos- ability and abstractness in the implementation of crosscut- ting concerns are typical requirements that these ...

A composite Higgs with a heavy composite axion [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We consider the strong dynamics associated with a composite Higgs model that simultaneously produces dynamical axions and solves the strong CP problem. The strong dynamics arises from a new Sp or SU(4) hypercolor gauge group containing QCD colored hyperfermions that confines at a high scale.

Mechanical Properties of Domestic T700 Grade Carbon Fibers/QY9611 BMI Matrix Composites

open access: yesJournal of Aeronautical Materials, 2017
The morphologies,surface energies and surface chemical properties of the domestic T700 grade carbon fiber and the T700S carbon fiber were characterized by using scanning electronic microscopy (SEM), inverse gas chromatography(IGC) and X-ray photoelectron

Preparation of amphiphilic magnetic polyvinyl alcohol targeted drug carrier and drug delivery research

open access: yesDesigned Monomers and Polymers, 2020
Currently, magnetic applications have great potential for development in the field of drug carriers. In this paper, Fe3O4-PVA@SH, an amphiphilic magnetically targeting drug carrier, was prepared by using Fe3O4 and PVA with thiohydrazide ...

Configural and featural information in facial-composite images [PDF]

open access: yes, 2014
Eyewitnesses are often invited to construct a facial composite, an image created of the person they saw commit a crime that is used by law enforcement to locate criminal suspects.

Concave Compositions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
Concave compositions are compositions (i.e. ordered partitions) of a number in which the parts decrease up to the middle summand(s) and increase thereafter. Perhaps the most surprising result is for even length, concave compositions where the generating function turns out to be the quotient of two instances of the pentagonal number theorem with ...

Introduction to composite materials

open access: yes, 1980
The combination of materials to form a new material system with enhanced material properties is a well documented historical fact. For example, the ancient Jewish workers during their tenure under the Pharaohs used chopped straws in bricks as a means of ...

Delamination localisation and length estimation in composite laminate beam by VSHM and pattern recognition methods [PDF]

open access: yes, 2010
The focus of this work is to investigate the delamination damage in laminate composite beams, to fix a Vibration-based structural health monitoring (VSHM) method for the laminate structures.
