Nomenclature and terminology for dendrimers with regular dendrons and for hyperbranched polymers (IUPAC Recommendations 2017)

Influence of trap location on the efficiency of trapping in dendrimers and regular hyperbranched polymers.

The trapping process in polymer systems constitutes a fundamental mechanism for various other dynamical processes taking place in these systems. In this paper, we study the trapping problem in two representative polymer networks, Cayley trees and Vicsek fractals, which separately model dendrimers and regular hyperbranched polymers. Our goal is to explore the impact of trap location on the effic...

Mechanisms of Light Energy Harvesting in Dendrimers and Hyperbranched Polymers

Since their earliest synthesis, much interest has arisen in the use of dendritic and structurally allied forms of polymer for light energy harvesting, especially as organic adjuncts for solar energy devices. With the facility to accommodate a proliferation of antenna chromophores, such materials can capture and channel light energy with a high degree of efficiency, each polymer unit potentially...

در هر برنامه آموزشی، مهم ترین فاکتور موثر بر موفقیت دانش آموزان کتاب درسی است (مک دونو و شاو 2003). در حقیقت ، کتاب قلب آموزش زبان انگلیسی است( شلدن 1988). به دلیل اهمیت والای کتاب به عنوان عنصر ضروری کلاس های آموزش زبان ، کتب باید به دقت ارزیابی و انتخاب شده تا از هرگونه تاثیر منفی بر دانش آموزان جلوگیری شود( لیتز). این تحقیق با طراحی پرسش نامه ارزیابی کتاب که فرصت ارزیابی معتبر را به اساتید د...

Local orientational mobility in regular hyperbranched polymers.

We study the dynamics of local bond orientation in regular hyperbranched polymers modeled by Vicsek fractals. The local dynamics is investigated through the temporal autocorrelation functions of single bonds and the corresponding relaxation forms of the complex dielectric susceptibility. We show that the dynamic behavior of single segments depends on their remoteness from the periphery rather t...
