Processing of nanotubes on NiTi-shape memory alloys and their modification with photografted anti-adhesive polymer brushes. Towards smart implant surfaces

open access: yesMaterials & Design, 2019
Implants based on NiTi shape memory alloys may be overgrown with cells which is undesirable in traumatology and stenting. The processing of a self-organized nanotube (NT) layer and its functionalization with a polymer that resists protein and cell ...

Model selection and model averaging on mortality of upper gastrointestinal bleed patients [PDF]

open access: yes, 2018
Model Selection (MS) is known to produce uncertainty into model-building process. Besides that, the process of MS is complex and time consuming. Therefore, Model Averaging (MA) had been proposed as an alternative to overcome the issues.

Challenges and Perspectives on Photocatalytic Membrane Reactors for Volatile Organic Compounds Degradation and Nitrogen Oxides Treatment. [PDF]

open access: yesGlob Chall
Photocatalytic membrane reactors (PMRs) find the synergy of membranes as flexible, stable, permeable hosts to incorporate photocatalytic materials. This combination has strong potential in air purification systems, particularly the decontamination of air via reactive‐species‐induced degradation of volatile organic compounds and nitrogen oxides.

Durability of biodegradable polymers for the conservation of cultural heritage [PDF]

open access: yes, 2019
The use of polymers for conservation of cultural heritage is related to the possibility to slow down or stop natural deterioration which, in many cases, corresponds to stopping the entrance of liquid water and to favor spontaneous water vapor removal ...
