Impact of Competitive Processes on Controlled Radical Polymerization

the impact of peer review on efl reviewers writing proficiency

امروزه تصحیح همکلاسی در کلاسهای نگارش یکی از اجزاء لاینفک کلاسهای دانش آموز محور است. تاثیرات مفید تصحیح همکلاسی بر زبان آموزان، معلمان را متقاعد کرده است که علیرغم صرف زمان، انرژی و توان بسیار، از این شیوه ی آموزشی در کلاسهای آموزش نگارش بهره بگیرند. تحقیق حاضر بر آن است تا با مقایسه دو گروه از یادگیرندگان زبان انگلیسی، تاثیر تصحیح همکلاسی را بر توانایی نوشتاری آنها نشان دهد. 122 خانم زبان آمو...

the impact of using inspirational quotes on abstract vocabulary recall

the present study is an attempt to investigate the potential impact of inspirational quotes on improving english abstract vocabulary recall. to achieve this goal, a multiple choice language proficiency test of 60 items including vocabulary and grammar component was administered to a sample of 63 second-semester male and female students whose age ranged between 17 to 22 and they were studying en...

Block and Graft Copolymerization by Controlled/Living Radical Polymerization Methods

Impact of Catalyst on the Stability of Initiators on Au Substrate in Atom Transfer Radical Polymerization

Desorption of thiol-based self-assembled monolayers on gold surfaces makes surface-initiated atom transfer radical polymerization (SI-ATRP) challenging and results in reduced density “grafted from” polymer fi lm. In this work, in situ attenuated total refl ectance-Fourier transform infrared (ATR-FTIR) spectroscopy shows that copper-based catalysts typically used in SI-ATRP cause substantial des...

Compression, supramolecular organization and free radical polymerization of ethylene gas

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...
