Coordinative Ring‐Opening Polymerization of Limonene Carbamate towards Phosgene‐ and Isocyanate‐Free Polyurethane

Angewandte Chemie International Edition, Accepted Article.
This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

Repeated chest wall reconstruction after resection of a sternal chondroid chordoma with long-term postoperative infection of the reconstructive material

Monaldi Archives for Chest Disease, 2023
We present the case of a 23-year-old man with a chondroid chordoma of the sternum. The patient underwent chest wall resection, followed by stabilization using a sandwich graft of Prolene mesh and methylmethacrylate, covered with bilateral pedicled M ...

Effects of a high‐fat diet on gut microbiota and possible implications for bone health in male Wistar rats

Lipids, EarlyView.
Abstract Diet plays an important role in the composition of gut microbiota. Emerging research suggests that bone homeostasis can also be influenced by the gut microbiota. The aim of this study was to assess possible alterations in gut microbiota in an experimental obesity model induced by a high‐fat diet (HFD) and the possible effects on parameters of ...

Spinal Fusion with Methylmethacrylate Cage [PDF]

, 2012
A brief history of anterior cervical decompression and fusion (ACDF) surgery is useful. The first reports on ventral approaches to cervical disc pathology appeared in the 1950s. Two most common methods for ACDF were described by Robinson and Smith in 1955 (1) and Cloward in 1958 (2).

Impact of Doping on Charge Transport Properties in Thienothiophene‐Based Organic Porous Polymers

Macromolecular Materials and Engineering, EarlyView.
Thienothiophene‐based organic porous conjugated polymers, possessing triphenylamine (TPA), tetraphenylethylene (TPE), and carbazole (Cbz) as linkers, display a higher charge transport property upon iodine doping. Abstract Organic covalent frameworks (COFs) have played significant roles in achieving high performance as electronic conductive and semi ...

Photonic Crystal Polymeric Thin-Film Dye-Lasers for Attachable Strain Sensors

Sensors, 2021
In this report, using two-dimensional photonic crystals (PhC) and a one-dimensional PhC nano-beam cavity, we realized the development of all-polymeric dye-lasers on a dye-doped, suspended poly-methylmethacrylate film with a wavelength-scale thickness. In

Antifouling Coatings Inspired by Biological Templates

Macromolecular Rapid Communications, EarlyView.
The polymeric coatings developed using biological templates combine antifouling properties of polymers with mechanical properties of micro‐ and nano‐particles yielding contact active, foulant releasable, and stimuli responsive materials with superior antifouling performance and demonstrate several applications in the marine environment, as delivery ...
