Macro and micro routes to high performance bioplastics: bioplastic biodegradability and mechanical and barrier properties
(MDPI, 2021-06-30)
: On a score sheet for plastics, bioplastics have a medium score for combined mechanical
performance and a high score for biodegradability with respect to counterpart petroleum-based
plastics. Analysis quickly confirms ...
Effect of thermal annealing on a bilayer polyvinyl alcohol/polyacrylic acid electrospun hydrogel nanofibres loaded with doxorubicin and clarithromycin for a synergism effect against osteosarcoma cells
(Elsevier, 2021-08-02)
Polyvinyl alcohol/polyacrylic acid (PVA/PAA) bilayer hydrogel nanofibres were successfully fabricated by
electrospinning and physically crosslinked via heat treatment. The effects of the thermal annealing
process on the ...
Treatment for the amelioration of persistent factors in complex anal fistula
(Springer, 2021-11-19)
Anal fistulae are abnormal hollow connections between the wall of the anal canal and the
perianal skin around the anus that have remained a burden on the medical sector for centuries.
The complexity of this disease is ...
Ti-25Nb-25Ta alloy treated by plasma electrolytic oxidation in phosphoric acid for implant applications
(Rede Latino-Americana de Materiais, 2021)
Among titanium alloys with non-toxic elements, the Ti-25Nb-25Ta alloy has good elastic behavior for applications in osseous implants, biocompatibility, and excellent corrosion resistance. The present study aimed to
better ...
Scratch-resistant and well-adhered nanotube arrays produced via anodizing process on β-titanium alloy
(Elsevier, 2021-03)
Well-adhered nanotube arrays were produced through the anodizing technique on a Ti-25Nb-25Ta alloy and tribo-mechanically evaluated by nanoindentation and nanoscratch tests. Disregarding substrate effects, the hardness of ...
Transfer and optimisation of injection moulding manufacture of medical devices using scientific moulding principles
(MDPI, 2021-10-25)
Scientific moulding, also known as decoupled injection moulding, is a production methodology used to develop and determine robust moulding processes resilient to fluctuations caused by variation in temperature and viscosity. ...
Application of biomaterials for complex anal fistulae
(Taylor & Francis, 2021-11-07)
Complex anal fistulae remain a challenge for the medical sector as conventional treatments put
patients at risk of incontinence. Clinicians and researchers have become interested in the application
of bioresorbable ...
On the possibility of replacement of calcium carbonate by a high-performance, economically viable filler in polyethylene composites
(Sage, 2021-07-14)
Calcium carbonate (CaCO3) is frequently added to polyethylene (PE) as a filler to reduce costs. An alternative to CaCO3, calcium fluoride (CaF2) was proposed in this research. PE/CaCO3 and PE/CaF2 composites in a wide ...
Evaluation of titanium nitride coatings in bandsaw blades for wood splitting by cold plasma
(Taylor & Francis, 2021-11-06)
Due to the advances in surface treatments, it is possible to obtain excellent cutting tools. However, the field for wood cutting tools still needs to be further investigated. In this work, titanium nitride was deposited ...
Digital twin: origin to future
(MDPI, 2021-05-24)
Digital Twin (DT) refers to the virtual copy or model of any physical entity (physical twin)
both of which are interconnected via exchange of data in real time. Conceptually, a DT mimics the
state of its physical twin ...
