Continuous Flow Block Copolymer Nanoaggregate Synthesis and Their Flow Dialysis Purification
Chemistry–Methods, EarlyView.This work details the methodology for the synthesis of block copolymer nanoparticles through continuous flow self‐assembly and purification via flow dialysis. Nanoaggregates are formed by mixing block copolymer solutions in THF with water, followed by dialysis to eliminate excess solvent.

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet
Communications on Pure and Applied Mathematics, EarlyView.Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

IET Nanodielectrics, Volume 5, Issue 3-4, Page 132-138, September-December 2022., 2022 In this investigation, we fabricated the PLLA (poly(L–lactic Acid)–based bimorph structures for piezoelectric minimotor applications. The PLLA bimorph minimotor showed the maximum load of 1.2 g and the maximum torque of 0.019 cN·m. Abstract Piezoelectric polymers have been widely used in a variety of applications, including tactile sensors, energy ...

Sustainable Synthesis of 1,2,3‐Triazoles using Cyrene as a Biodegradable Solvent in Click Chemistry
ChemSusChem, EarlyView.Green triazoles: The first successful synthesis of 1,2,3‐triazoles using Cyrene as a biodegradable and non‐toxic solvent in click chemistry has been developed. This sustainable approach allows product isolation by simple precipitation in water, eliminating the need for organic solvent extractions and chromatographic purifications, thus minimizing waste
