We are investigating different micro- and nano-structure approaches to neutron detection based on inorganic scintillators. Specifically, we have been assessing various converter-scintillator configurations through simulations experiments. One promising scintillator is ZnO due its relatively high light yield [1] , reasonable optical transparency in the visible region [2] low refractive index [3]...

Abstract Recently, many studies have investigated additive manufacturing (AM) of hierarchical surfaces with high surface area/volume (SA/V) ratios, and their performance has been characterized for applications in next-generation functional devices. Despite recent advances, it remains challenging to design manufacture SA/V ratio structures desired functionalities. In this study, we established t...

طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...

Many efforts are currently made to increase the limited capacity of Li-ion batteries using carbonaceous anodes. The way to reach this goal is to move to nano-structured material because the larger surface to volume ratio of particles and the reduction of the electron and Li path length implies a larger specific capacity. Additionally, nano-particles can accommodate such a dilatation/contraction...

A series of novel nano-structured manganese pyranopyrazole Schiff base complex (3a-l) has been synthesized and described. This synthetic complexation involved sequential reactions domino four-component one-pot reaction for the template (1), imination (2) finally completed by with to furnish title compounds (3a-l). The salient this nano-Schiff protocol is that diverse chemical functionalities we...
