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

Macromolecular 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 ...

Cloning Your Gadgets: Complete ROP Attack Immunity with Multi-Variant Execution

IEEE Transactions on Dependable and Secure Computing, 2016
In this paper, we present disjoint code layouts (DCL), a technique that complements multi-variant execution [1] and W$\oplus$ X protection to effectively immunize programs against control flow hijacking exploits such as return oriented programming (ROP) [

Mechanophoric 3‐Arm Star Functional Block Copolymer Based on Rhodamine Derivative

Macromolecular Materials and Engineering, EarlyView.
Mechanoresponsive rhodamine containing linear and star block and random copolymers were synthesized and characterized. All materials transitioned into a “switch‐on” state in the film form, but only the star block copolymer architecture exhibited a complete and precise peak shift upon stretching, providing new insights into the mechanochemical ...

Formulation of Raw Material Inventory Model in The Steel Industry

Jurnal Ilmiah Teknik Industri
Suboptimal inventory management can lead to overstocks that increase storage costs or shortages that hamper production. PT XYZ, a manufacturer of automotive components, faces this challenge, especially in the management of steel raw materials. This study

From Molecule to Material: How Support Changes Heterobimetallic Catalysts in Lactide Polymerization

Macromolecular Rapid Communications, EarlyView.
Silica‐supported heterobimetallic alkoxide complexes were developed as catalysts for lactide ring‐opening polymerization. Grafting iron‐based ate complexes onto SiO2‐700 produced well‐defined active sites, enabling controlled polymerization with predictable molar masses, narrow dispersities, and recyclability.

Poly(sarcosine) Lipid Synthesis From CO2‐Based Sarcosine‐N‐Carboxyanhydride

Macromolecular Rapid Communications, EarlyView.
In this work, we optimize and scale‐up a CO2‐based synthesis of sarcosine‐N‐carboxyanhydride (Sar‐NCA) to the gram scale. The low toxicity and simplicity of the approach make it an attractive alternative to current toxic phosgene‐based approaches. The CO2‐based Sar‐NCA has sufficient purity for controlled polymerization.

Disulfide‐Induced Inhibition of Epoxy Cationic Photopolymerization: A Route to Maskless Patterning

Macromolecular Rapid Communications, EarlyView.
This study investigates the role of disulfide‐containing molecules on the photopolymerization of epoxy monomers through cationic ring‐opening reaction, with the demonstration of the selective inhibition of the polymerization when disulfides are added to the photocurable formulation. This quenching is then exploited as a novel maskless photolithographic
