Melt electrowriting of poly(ϵ-caprolactone)—poly(ethylene glycol) backbone polymer blend scaffolds with improved hydroph...

Published in Biomedical Materials

Melt electrowriting (MEW) is an additive manufacturing technique that harnesses electro-hydrodynamic phenomena to produce 3D-printed fibres with diameters on the scale of 10s of microns. The ability to print at this small scale provides opportunities to create structures with incredibly fine resolution and highly defined morphology. The current gol...

Parking Lot Occupancy Detection with Improved MobileNetV3.

Published in Sensors (Basel, Switzerland)

In recent years, parking lot management systems have garnered significant research attention, particularly concerning the application of deep learning techniques. Numerous approaches have emerged for tackling parking lot occupancy challenges using deep learning models. This study contributes to the field by addressing a critical aspect of parking l...

Graphene-Based Flexible Strain Sensor Based on PDMS for Strain Detection of Steel Wire Core Conveyor Belt Joints.

Published in Sensors (Basel, Switzerland)

Because of their superior performance, flexible strain sensors are used in a wide range of applications, including medicine and health, human-computer interaction, and precision manufacturing. Flexible strain sensors outperform conventional silicon-based sensors in high-strain environments. However, most current studies report complex flexible sens...

Current Standing on Radical Ring-Opening Polymerizations of Cyclic Ketene Acetals as Homopolymers and Copolymers with on...

Published in Macromolecular rapid communications

Radical Ring-opening polymerization (RROP) of cyclic ketene acetals (CKAs) emerges to be a valuable polymerization technique. In attracting more attention, RROP has seen a new spike in publications, which the authors will put into perspective. This review will hence address the progress made on the number of available CKAs and the synthetic strateg...

Lipase-Catalysed Polymerization of Eutectic Mixtures.

Published in ChemSusChem

Aiming to reduce the toxicity and operational costs often associated to chemical processes, the enzymatic synthesis is applied herein as a sustainable route for producing polyesters. The use of NADES' (Natural Deep Eutectic Solvents) components as a source of monomers for the synthesis of polymers through lipase-catalyzed esterification in an anhyd...

Treatment of gummy smile combining crown lengthening, lip repositioning, and the use of polyester threads.

Published in Clinical advances in periodontics

The case report presents a new possibility of treatment for a gummy smile in a patient with multiple etiologies, such as altered passive eruption and hypermobility upper lip. At first, crown lengthening was not sufficient to achieve the desired aesthetic result, being necessary its combination with lip repositioning. Crown lengthening surgery (CLS)...

Synthesis, characterization, thermal stability, and in vitro and in vivo degradation study of polycaprolactone and polyg...

Published in Journal of biomaterials science. Polymer edition

Biodegradable polymer materials are attractive in various biomedical applications. Herein, we report a block aliphatic copolymer, polycaprolactone-block-polyglycolide (PCL-b-PGA, denoted as PCLGA), and explored the polymer composition effect on the thermal and degradation behaviors. Three copolymers with different PCL/PGA weight ratios were obtaine...

Harnessing the Potential of Fibrous Polyester Composites Meant for Bioactive Medical Devices

Fibrous-based composite polyester mats have gained importance in the biomedical area due to their morphological characteristics and mechanical performance. These materials can be modified by incorporating different inorganic micro- or nano-particles, thus leading to promising potential applications as medical devices with antimicrobial and/or bioac...
