A novel, non-covalent polymeric nanosheet has been produced through small molecule self-assembly; the structure has been characterized by solution NMR, solid-state NMR, powder XRD and AFM.

5-Fluorouracil (5-FU) is an anticancer drug. In this work, we have investigated the electronic properties and topological analysis of interaction between 5-FU and carbon nanocone and BN nanocone. The structural stability of isomer complexes of 5-FU with carbon nanocone and BN nanocone have been investigated for two position of interactions. We have found that the most stable complexes are forme...

یکی از مسائل مهم در مدیریت منابع آب، تهیه و توسعه مدل‌های مناسب به منظور پیش‌بینی دقیق‌تر فرآیند جریان رودخانه‌ها می‌-باشد. بدین منظور در مطالعه حاضر برای پیش‌بینی جریان ماهانه رودخانه بختیاری، در دوره آماری 1395-1334، از مدل‌های سری-زمانی خطی (ARMA)، مدل هوشمند شبکه بیزین (BN) و مدل تلفیقی BN-ARMA استفاده شد. عملکرد مدل‌های توسعه یافته براساس شاخص‌های آماری جذر میانگین مربعات خطا (RMSE)، ضریب ...

A novel approach to synthesize graphene nanosheet is explored on the basis of the layer-by-layer (LbL) self-assembly of polyallylamine (PAA) and poly(styrene-sulfonate) (PSS) multi-layer with a metallic dopant.

We report the fabrication technique and optical properties of multilayered two-dimensional (2D) gold nanoparticle sheets ("Au nanosheet"). The 2D crystalline monolayer sheet composed of Au nanoparticles shows an absorption peak originating from a localized surface plasmon resonance (LSPR). It was found that the absorption spectra dramatically change when the monolayers are assembled into the mu...

A novel and facile strategy is developed to fabricate highly nitrogen-doped graphene (N-graphene) based layered, quasi-two-dimensional nanohybrids with ultrathin nanosheet nanocrystals using a low-temperature, solution processing method for high-performance supercapacitor electrodes. High N doping can be achieved together with one of the lowest oxygen content in chemically reduced graphene and ...

Nanostructured MoS2 is very promising as an electrocatalyst for hydrogen evolution due to a greater number of active edge sites. However, a very large resistance between basal planes decreases the overall efficiency of hydrogen evolution, and greatly limits its application in industry. Herein we develop a facile strategy to synergistically increase the number of active edge sites and the conduc...

We report on the nanosheet-thickness effects on the performance of top-gate MoS(2) field-effect transistors (FETs), which is directly related to the MoS(2) dielectric constant. Our top-gate nanosheet FETs with 40 nm thin Al(2)O(3) displayed at least an order of magnitude higher mobility than those of bottom-gate nanosheet FETs with 285 nm thick SiO(2), benefiting from the dielectric screening b...

We here demonstrated a novel square silica/titania mesoporous nanosheet which was prepared with hyperbranched poly(ether amine) nanosheets (hPEA-NSs) as a template. TEM and SEM images reveal that the obtained nanosheets possess a large aspect ratio with the average edge length of 1-2 μm and thickness of ~40 nm, respectively. Various metal nanoparticles such as gold, silver, and platinum can be ...
