[ 1 ] - امکان‌سنجی فنی، اقتصادی و زیست‌محیطی جایگزینی گرمایش شهری متعارف با انرژی زمین گرمایی در ایران

زمینه و هدف: بهره‌برداری از انرژی زمین گرمایی برای گرمایش محیطی و منطقه‌ای، یکی از مناسب‌ترین و متداول‌ترین روش‌های استفاده مستقیم از حرارت زمین است که چندین دهه تجربه در مناطق وسیعی از جهان، باعث کسب اطلاعات مفیدی از نحوة اجرای پروژه‌های زمین گرمایی و نتایج حاصل گردیده است. هدف از این تحقیق جایگزینی سوختهای فسیلی در گرمایش و تامین آبگرم مصرفی ساختمان ها با انرژی تجدیدپذیر زمین گرمایی برای کاه...

[ 2 ] - امنیت انسانی و چالش‌های توسعه انرژی‌های تجدیدپذیر در ایران، با تاکید بر امنیت زیست محیطی

زمینه و هدف: امنیت زیست محیطی به عنوان یکی از ابعاد هفتگانه امنیت انسانی با چگونگی استفاده از منابع انرژی‌ رابطۀ تنگاتنگی دارد. مدیریت بخش انرژی با کاهش آلودگیهای زیست محیطی نقش کلیدی در دستیابی به توسعه پایدار ایفا می‌کند و توسعه پایدار بدون تامین امنیت زیست محیطی امری غیر ممکن است. به عبارت بهتر انرژی با امنیت و توسعه ارتباط مستقیمی دارد. متخصصین و برنامه‏ریزان انرژی در دنیا اتفاق نظر دارندک...

[ 3 ] - Et3N as a catalyst for the synthesis of indeno[1,2-b]chromene derivatives via three-component condensation reaction

Functionalized indeno[1,2-b]chromene derivatives have been synthesized via condensation reaction of 1H-indene-1,3(2H)-dione with benzaldehyde and cyclization with 2-hydroxynaphthalene-1,4-dione in the presence of a catalytic amount of triethylamine (Et3N) in EtOH at room temperature. It was observed that benzaldehyde bearing electron donating group gave high yield of product, whereas, benzaldeh...

[ 4 ] - Synthesis and Biological Evaluation of Thiosemicarbazide Derivatives Endowed with High Activity toward Mycobacterium Bovis

Thiosemicarbazides are potent intermediates for the synthesis of pharmaceutical and bioactive materials and thus, they are used extensively in the field of medicinal chemistry. The imine bond (-N=CH-) in these compounds are useful in organic synthesis, in particular for the preparation of heterocycles and non-natural β-aminoacids.In this paper the synthesis of some new thiosemicarbazide derivat...

[ 5 ] - Synthesis of Novel Fluorene Bisamide Derivatives via Ugi Reaction and Evaluation their Biological Activity against Mycobacterium species

A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done to. These compounds were evaluated as anti-bac...

[ 6 ] - Synthesis and Characterization of Biodegradable Semi-Interpenetrating Polymer Networks Based on Star-Shaped Copolymers of ɛ-Caprolactone and Lactide

In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...
