Numerous companies working in the field of membrane development, production, and separation engineering were present at ACHEMA 2022. Compared to last 2018, there fewer attending only few new topics since development has been blocked partially by pandemic situation subsequent restrictions this years. Nevertheless, some developments have identified concerning process design as well ceramic polyme...

We present a DNA-containing polymeric nanocontainer using the self-assembled superstructure of amphiphilic block copolymers in aqueous solutions. To demonstrate that DNA translocation is possible across a completely synthetic block copolymer membrane, we have used a phage transfection strategy as a DNA-transfer model system. For this purpose the bacterial channel forming protein LamB was recons...

sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of vo2+ in aqueous solutions. the sol-gel and pvcmembrane electrodes exhibited linear response with nernstian slopes of 29.3 and 28.4 mv perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...

In this work, we report a novel method for selective oxidation of benzyl alcohols to benzaldehydes. Neither solvent nor promoters are needed: a polymeric microporous membrane acts as a barrier to “keep in contact” the two phases: the organic phase containing the substrate, benzyl alcohols and the products, benzaldehydes and the aqueous phase with the catalyst and the oxidant, hydrogen peroxide....

This study presents the development of natural rubber-Ca/P blends, as promising candidates for biomedical purposes. The specific objective was the incorporation of Ca/P into a natural rubber polymeric matrix. Ca/P crystalline phases were synthesized by the sol-gel method and the polymeric matrices were produced using natural rubber extracted from latex of the Hevea brasiliensis. The shape and s...
