Propolis-Based Nanofiber Patches to Repair Corneal Microbial Keratitis

2021

In this research, polyvinyl-alcohol (PVA)/gelatin (GEL)/propolis (Ps) biocompatible nanofiber patches were fabricated via electrospinning technique. The controlled release of Propolis, surface wettability behaviors, antimicrobial activities against the S. aureus and P. aeruginosa, and biocompatibility properties with the mesenchymal stem cells (MSCs) were investigated in detail. By adding 0.5, 1, and 3 wt.% GEL into the 13 wt.% PVA, the morphological and mechanical results suggested that 13 wt.% PVA/0.5 wt.% GEL patch can be an ideal matrix for 3 and 5 wt.% propolis addition. Morphological results revealed that the diameters of the electrospun nanofiber patches were increased with GEL (from…

Dažādu oglekļa bāzētu materiālu elektrodu pielietojamība mikroorganismu degvielas šūnās

2016

Darba mērķis bija novērtēt grafīta, grafēna un grafēna-PLA kompozīta elektrodu pielietojamību MFC. Darbā konstruētas 8 sendviču tipa šūnas ar agara tiltiņu un 8 šūnas ar Nafion212 membrānu. 8 šūnas darbojās ar ezera dūņām, 8 ar P. aeruginosa tīrkultūru. MFC mērītas polarizācijas līknes un iegūts maksimālais jaudas blīvuma parametrs. Maksimālo MFC jaudas blīvumu uzrādīja 3D printēta grafēna-PLA, Nafiona212 un P. aeruginosa kombinācija – attiecīgi 35,8 mW/m2. Grafēna-PLA elektrodu voltametrija uzrādīja sliktākas elektroķīmiskās īpašības, nekā grafītam. Tomēr MFC šūnās elektrodi strādāja tikpat labi un labāk kā grafīts, kas norāda uz labāku biosaderību. Darbs izstrādāts periodā no 2015. gada d…
