جنس plantago متلق به تیره بارهنگ (plantaginaceae) با بیش از 200 گونه به عنوان یک داروی خام در کشورهای شرق آسیا و ایران مورد استفاده قرار می گیرد و دارای خواص پاد اکسایشی و ضدرادیکالی می باشد. در این مطالعه مشخصات آناتومیکی و میزان محتوای کل فنول و فعالیت ضدرادیکالی عصاره ی اتانولی و متانولی ریشه ، برگ و گل آذین سه گونه گیاه بارهنگ شامل: p.lanceolata ، p. major و p. maritima در استان آذربایجان غ...
All-solid-state lithium battery has become one of the most promising secondary batteries due to their high energy density and excellent safety. However, growth dendrites side reactions between metal solid electrolytes hinder practical application all-solid-state batteries. Herein, a dual-functional layer ZnO LiF is fabricated at interface Li10GeP2S12 electrolyte by magnetic sputtering technique...
The all-inorganic nature of CsPbI3 perovskites allows to enhance stability in perovskite devices. Research efforts have led improved the black phase films; however, these strategies-including strain and doping-are based on organic-ligand-capped perovskites, which prevent from forming close-packed quantum dot (QD) solids necessary achieve high charge thermal transport. We developed an inorganic ...
We numerically analyze a polarization maintaining (PM) supercontinuum generation (SCG) in all-normal dispersion liquid (CS 2 )-core photonic crystal fiber (LC-PCF). The proposed LC-PCF affords high birefringence (10 −3 to 10 xmlns:xlink="http...
The international airport of Heathrow is a major source of nitrogen oxides, but its contribution to the levels of sub-micrometre particles is unknown and is the objective of this study. Two sampling campaigns were carried out during warm and cold seasons at a site close to the airfield (1.2 km). Size spectra were largely dominated by ultrafine particles: nucleation particles (< 30 nm) were foun...
A (100 ? x )Li 2 S· AlI 3 (0 ? 30) positive electrode was prepared by the planetary ball-milling method for application in all-solid-state Li–S batteries.
We report a successful fabrication of long-length RABiTS-based coated conductors (CC) via chemical solution deposition starting from colloidal YBa2Cu3O7-δ (YBCO) solutions containing 5 mol-% preformed BaMO3 (M = Hf, Zr) nanocrystals. Partial optimization the existing continuous reel-to-reel YBCO processing design experiments (DoE) approach allowed us to obtain nanocomposites that retain 80-90% ...
In article number 2003190, Kyung-Wan Nam, Yoon Seok Jung and co-workers develop a new halide solid electrolyte, Fe3+-substituted Li2ZrCl6, that is mechanically sinterable, (electro)chemical-oxidation tolerant, free of rare-earth metals. The outstanding performance the all-solid-state batteries using LiCoO2 LiNi0.88Co0.11Al0.01O2 enabled by use newly developed superionic conductors.
In the light of various studies carried out in various socio-economic areas, scientific and cultural development has been introduced as a prerequisite and fundamental factor for sustainable development of the societies. Obviously, universities, as a "scientific and intellectual command center of the society" have a fundamental and unique role and function. In order to achieve this, the most sig...
