Physical properties of shellac material used for hot melt extrusion with potential application in the pharmaceutical industry
(MDPI, 2021-10-28)
Hot melt extrusion offers an efficient way of increasing the solubility of a poorly soluble
drug. Shellac has potential as a pharmaceutical matrix polymer that can be used in this extrusion
process, with further advantages ...
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 ...
Antimicrobial PAA/PAH electrospun fiber containing green synthesized zinc oxide nanoparticles for wound healing
(MDPI, 2021-05-27)
Wound infections are the main complication when treating skin wounds. This work reports a novel antimicrobial material using green synthesized zinc oxide nanoparticles (ZnONPs) incorporated in polymeric fibers for wound ...
Upcycling biodegradable PVA/starch film to a bacterial biopigment and biopolymer
(MDPI, 2021-10-27)
Meeting the challenge of circularity for plastics requires amenability to repurposing post-use, as equivalent or upcycled products. In a compelling advancement, complete circularity for a biodegradable polyvinyl ...
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 ...
An extensible parsing pipeline for unstructured data processing
(IEEE, 2021-03-10)
Network monitoring and diagnostics systems depict the running system's state and generate enormous amounts of unstructured data through log files, print statements, and other reports. It is not feasible to manually analyze ...
