The Crystallization Kinetics in Semicrystalline Nanocomposites [PDF]

open access: yes, 2010
Růst krystalů zásadně ovlivňuje morfologii a tím také mechanické vlastnosti semikrystalických polymerů. Tato PhD práce přináší alternativní pohled na popis kinetiky krystalizace v polyolefinech plněných slabě interagujícími částicemi.

Polyethylenes

open access: yesTransactions of The Electrochemical Society, 1946
This paper is a discussion of data which have been obtained on polymers of ethylene over a wide molecular weight range. Following a brief description of the methods used in grading or identifying these polymers, specific properties are discussed. Data are given for a number of mechanical properties and their variations with molecular weight are shown ...

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Tensile mechanical response of polyethylene – clay nanocomposites.

open access: yeseXPRESS Polymer Letters, 2007
In this work we report on the microstructural and the mechanical characteristics of high density polyethylene (HDPE)-clay nanocomposites, with particular attention to the creep behaviour. The samples were prepared through melt compounding, using two high-

Blends of linear-low-density polyethylene and thermoplastic bloodmeal using maleic anhydride grafted polyethylene as compatibilizer [PDF]

open access: yes, 2012
Linear Low-Density Polyethylene (LLDPE) was blended with Novatein Thermoplastic from bloodmeal (NTP.) The compatibilizing effect of maleic anhydride grafted polyethylene (PE-g-MAH) on mechanical, morphology thermal properties and water absorption were ...

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami

open access: yesAdvanced Functional Materials, EarlyView.
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

Effects Of Electron Beam Irradiation On The Mechanical Properties Of Ethylene Octene Copolymer, Polypropylene and Trimethylolpropane Triacrylate Blends [PDF]

open access: yes, 2005
The effect of electron beam irradiation on blends of ethylene-octene copolymer (EOC) and polypropylene (PP) with and without trimethylolpropane triacrylate (TMPTA) at various ratios was studied.

A 3D Biofabricated Disease Model Mimicking the Brain Extracellular Matrix Suitable to Characterize Intrinsic Neuronal Network Alterations in the Presence of a Breast Tumor Disseminated to the Brain

open access: yesAdvanced Functional Materials, EarlyView.
A 3D disease model is developed using customized hyaluronic‐acid‐based hydrogels supplemented with extracellular matrix (ECM) proteins resembling brain ECM properties. Neurons, astrocytes, and tumor cells are used to mimic the native brain surrounding.
