Tungsten Disulfide-Based Materials and Their Conjugates for Cancer Photothermal...

Cancer remains one of the most critical global health issues. Conventional treatments, such as radiotherapy, surgery, or chemotherapy, have limitations, especially concerning side effects, resistance, and recurrence. Consequently, new innovative treatments to overcome these problems are needed. Photothermal therapy (PTT) is a promising alternative that uses photothermal agents that convert near-infrared light (...

Experiment and modelling of the strain-rate-dependent response during in vitro ...

Polylactic acid (PLA) fibres present, in their pristine state, a strain-rate-dependent behaviour. Their mechanical properties evolve during in vitro biodegradation. Tensile tests of PLA fibres are performed at five different strain rates 0.0001, 0.001, 0.01, 0.05 and 0.1/s and at seven degradation stages, 0, 20, 40, 60, 90, 120 and 150 days in a phosphate buffer solution at constant temperature at 37 degrees C....

Fabrication and antimicrobial performance of surfaces integrating graphene-base...

Although graphene-based materials (GBMs) have been thoroughly explored, their use in antimicrobial surfaces is still a developing field. This review overviews the different methods for fabricating GBMs-containing surfaces (free-standing films, coatings or bulk composites) and their antibacterial properties. The difficulty in controlling the broad number of factors affecting interactions between GBMs and bacteri...

Biocompatible reinforcement of poly(Lactic acid) with graphene nanoplatelets

A recently made available form of graphene nanoplatelets (GNP-C) is investigated for the first time as reinforcement filler for PLA. GNP-C, with thickness of about 2 nm and length 1-2 m, was incorporated at different loadings (0.1-0.5 wt%) in poly(lactic acid) (PLA) by melt blending. The effect of varying mixing time and mixing intensity was studied and the best conditions were identified, corresponding to mixi...

Poly(lactic acid) composites containing carbon-based nanomaterials: A review

Poly(lactic acid) (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites. It is also approved by regulatory authorities for several biomedical applications. However, for some uses it is required that some of its properties be improved, namely in terms of thermo-mechanical and electrical performance. Th...

Determination of resin and moisture content in melamine-formaldehyde paper usin...

This paper describes the use of near infrared spectroscopy as a tool for the determination of moisture and resin content on papers impregnated with melamine-formaldehyde resins for high-pressure laminate production. The papers had different colours and grammages. The near infrared analysis range comprised wavelengths between 12,000 cm(-1) and 4000 cm(-1). Several multivariate calibration procedures and pre-proc...

Recent developments on intramedullary nailing: a biomechanical perspective

Combining contributions from engineering and medicine, we highlight the biomechanical turning points in the historical evolution of the intramedullary nailing stabilization technique and discuss the recent innovations concerning increase in bone-implant system stability. Following the earliest attempts, where stabilization of long bone fractures was purely based on intuition, intramedullary nailing evolved from...
