Properties of TFX-A product obtained from calf thymus

Properties of TFX--a product obtained from calf thymus by Pharmaceutical Comp. in Jelenia Góra--are described. The preparate is a mixture of polypeptides and peptides of various molecular weights with various biological activities. Attempts of isolation of active fractions, devoid of balast proteins are described.     

A phenol-formaldehyde resin loaded with in situ synthesised silver nanoparticles

Attempts to obtain stable phenol-formaldehyde resins with silver nanoparticles embedded in their structure were performed in the study. Silver nanoparticles were formed in situ in the process of obtaining resole resins. The conditions of their formation allowed for effectively reducing silver ions and stabilising the creation of nanoparticles. Tannic acid was used as a reducing and stabilising substance and gelatin served as a supporting stabiliser. The possibility of using the obtained product as a wood binder was studied. It was confirmed that their adhesive properties are strong enough to bind blocks of pine wood. Thanks to the presence of silver nanoparticles, the product also exhibited antimicrobial activity which was confirmed against the Saccharomyces cerevisiae strain.
