Exploring the effect of utilising organic acid solutions in ultrasound-assisted extraction of pectin from apple pomace, and its potential for biomedical purposes

“…The tested pectin solutions show G′ and G″ values of few Pa, highlighting the potential of this material to be applied in the field of soft tissue engineering and regenerative medicine as the mechanical properties of several human tissues are in the range from few Pa to kPa [ 54 ].…”

A Brief Review on Selected Applications of Hybrid Materials Based on Functionalized Cage-like Silsesquioxanes

“…The trans isomer of DDSQ can serve as a bisfunctional POSS model. We have reported on a family of methacrylate-substituted DDSQs, which exhibit improved mechanical properties and cell adhesion compared to pure organic methacrylates ( Figure 6 ) [ 51 ]. To enhance the hydrophilicity of the DDSQ-based composites, polyvinyl alcohol (PVA) was used.…”

Exploring Polyol-Functionalized Dendrimers with Silsesquioxane Cores

“…11−13 There are numerous scientific reports on the use of diol derivatives of SQs as comonomers of polyesters or polyurethanes 14−24 and also in the chemistry of biomedical materials. 25 In addition, they have been reported in materials to remove dyes from wastewater or Ag(I) ions from aqueous solutions. 26,27 Within the domain of organosilicon chemistry, one may encounter dendritic architectures characterized as precisely structured three-dimensional macromolecular systems.…”

“…SQs are a family of structures, which could be divided into random resins or defined architectures, i.e., ladder, open- and closed-cage silsesquioxanes and double-decker silsesquioxanes (DDSQ). − The multiplicity of structures and the presence of various reactive groups, e.g., Si–OH, Si–H, Si–HCCH 2 , enable their modification by stoichiometric (condensation, nucleophilic substitution) and catalytic reactions (hydrosilylation, metathesis, Heck or Sonogashira coupling, O -silylation) . As a result, diverse silsesquioxane-based functionalized systems are obtained that may exhibit interesting physicochemical properties that affect their possible application, resulting in the use of, i.e., materials chemistry, OLEDs, catalysis, or medicine. − Within the great variety of functional groups, the SQs possessing hydroxyl-terminated aliphatic substituents may be of special concern. − There are numerous scientific reports on the use of diol derivatives of SQs as comonomers of polyesters or polyurethanes − and also in the chemistry of biomedical materials . In addition, they have been reported in materials to remove dyes from wastewater or Ag­(I) ions from aqueous solutions. , …”
