امروزه کنترل آفات انباری بیشتر با استفاده از آفت کشها و ترکیبات شیمیایی گازی صورت می گیرد. استفاده مکرّر از این مواد طی دهه های متوالی باعث از بین رفتن دشمنان طبیعی ، اختلال در کنترل بیولوژیک، اثر روی موجودات غیر هدف، آلودگی محیط زیست، در خطر قرار گرفتن سلامت انسان، طغیان آفات و بروز مقاومت در آفات هدف گردیده است (lee et al., 2001). با توجه به ناگزیر بودن بشر در استفاده از حشره کش ها، حشره کش ها...
Interest in MXenes is quite high because of their potential a wide range applications. Although several have been discovered to date, most studies so far focused mainly on Ti3C2Tz. Given 2D nature and rich surface chemistry, XPS the preferred technique for analyzing compositions. To only four understanding fitting spectra Ti3C2Tx flakes. While there are commonalities between various protocols, ...
Triboelectric nanogenerators (TENGs) have been utilized to harvest various forms of mechanical energy from the environment as a sustainable power supply. However, TENGs usually generate high output voltages but low currents, limiting their potential uses. Hybrid harvesters based on provide promising method effectively use environmental conditions for harvesting by combining two or more working ...

RECENT WORK ON INTERDISCIPLINARITY and knowledge growth has produced a variety of models to capture a process of bewildering complexity. Prominent among these are organic models, which compare knowledge growth to biological processes (e.g., hybridization), and spatial models, based on various suggestive geographical parallels. Part of the background of the dynamic formation, interaction, and di...
