Push-pull nitronates in the [3+2] cycloaddition with nitroethylene: Molecular Electron Density Theory study

open access: yesJournal of Molecular Graphics and Modelling, 2020
The structure and the participation of the N-methoxy-N-[bis(methoxycarbonyl)methylene]amine N-oxide as model push-pull nitronate 1 with nitroethylene 2 in [3 + 2] cycloaddition (32CA) reaction have been analyzed within the Molecular Electron Density Theory (MEDT) using Density Functional Theory (DFT) calculations at the B3LYP(PCM)/6-31G(d) level ...

Protein-ligand binding affinities from large-scale quantum mechanical simulations

open access: yes, 2012
The accurate prediction of protein-drug binding affinities is a major aim of computational drug optimisation and development. A quantitative measure of binding affinity is provided by the free energy of binding, and such calculations typically require ...

Relativistic DFT calculations for neutral and singly charged Au2

open access: yesMuthanna Journal of Pure Science
The study explores the use of relativistic Density Functional Theory (DFT) using the Gaussian09 package to analyze the geometry optimization of gold diatoms in various ionic states. The optimization is performed at multiple theoretical levels, including

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

First-Principles Study of Doping in LiMnPO4

open access: yesInternational Journal of Electrochemical Science, 2012
A density function theory (DFT) based first-principles study of doping on LiMnPO4 is attempted. The doped LiMnPO4, such as LiMn0.75Fe0.25PO4, LiMn0.75Al0.25PO4 and LiMnPO3S at the level of electron structure is studied. Highest occupied molecular orbital

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Graph Theory and Molecular Orbitals. XVI. on π-Electron Charge Distribution [PDF]

open access: yes, 1976
An integral formula is derived exhibiting the dependence of the π-electron charge density (in the framework of Huckel theory) on the coefficients of the characteristic polynomial of the molecular graph and one of its subgraphs.
