Impact of E‐Beam Sterilization on Bioglass Composite Shape Memory Scaffolds

open access: yesMacromolecular Materials and Engineering, EarlyView.
Electron beam (E‐beam) sterilization is an attractive alternative to conventional methods (e.g., ethylene oxide) to sterilize medical devices such as scaffolds used to heal bone defects. Herein, the impact of E‐beam sterilization on the properties of “self‐fitting” shape memory polymer (SMP) scaffolds prepared from resorbable polyesters and a bioglass ...

Apply to the Field of Optoelectronics by Examining Structural, Electronic, Optical, Mechanical, and Thermophysical Properties of FrBeX3 (X = Cl and Br) Perovskites

open access: yesNano Select, EarlyView.
FrBeCl3 and FrBeBr3 are semiconductors with suitable band gaps for optoelectronic devices. Bonding analysis shows strong covalent and moderate ionic character. Both compounds are mechanically stable and ductile. FrBeBr3 has a higher dielectric constant, favoring solar use.

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

open access: yesPolymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content

open access: yesPlasma Processes and Polymers, EarlyView.
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...
