Self Dilution of Model Polystyrene Pom‐Poms and Combs by Unentangled Side Arms

Macromolecular Rapid Communications, EarlyView.
This study uses experimental rheological data of 4 model polystyrene pom‐poms and 2 model polystyrene combs, all with unentangled arms, and constitutive modelling using Enhanced Relaxation of Stretch (ERS) model to show that the elongational rheology of the branched polymers is equivalent to that of polymer melts consisting of long linear chains ...

Material Development and Foam Extrusion Processing of Thermoplastic Starch‐Based Compounds

Polymer Engineering &Science, EarlyView.
Schematic representation of the project: a compound material based on thermoplastic starch and PBAT is developed for further processing in the foam extrusion process to achieve a flexible foam sheet with a low density and fine‐pored foam structure. ABSTRACT An investigation into the properties of starch‐based compounds is conducted to determine their ...

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

Progress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Biodegradability of Low Density Polyethylene (LDPE) and Discovery of LDPE-Degrading Microbes

NIPPON GOMU KYOKAISHI, 2007
Three types of low density polyethylene (LDPE)-degrading microbes were discovered, and unambiguous evidence for biodegradation of LDPE was presented. Pieces of LDPE film, buried and biodegraded, and their surrounding soil were used as the source of microbes.

Optimization of Microfibrillated and Nanofibrillated Cellulose Coating to Improve Performance of Paperboard Intended for Food Packaging Applications

Packaging Technology and Science, EarlyView.
This study aims to optimise the application methods of a biobased suspension of micro/nano cellulose fibrils from agro‐biomass subjected to high‐pressure homogenisation. Two methods were selected, bar coating (BC) and spray coating (SC), and were tested using an LF factorial design with 3 levels and 2 factors.

A Bootstrap Lasso + Partial Ridge Method to Construct Confidence Intervals for Parameters in High-dimensional Sparse Linear Models

, 2020
Constructing confidence intervals for the coefficients of high-dimensional sparse linear models remains a challenge, mainly because of the complicated limiting distributions of the widely used estimators, such as the lasso.
