Theoretical evidence for stereoselective lithiations of 2-alkoxy-1,1-diiodo-1-alkenes. An ab initio study [PDF]

open access: yes, 1997
Ab initio calculations with complete geometry optimization are reported for monomeric Z- and E-2-methoxy-1-iodo-1-lithio-2-phenyl-1-alkenes. All the stationary points are true local minima on the energy surfaces.

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

open access: yesAdvanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Accurate ab initio ro-vibronic spectroscopy of the X2∏ CCN radical using explicitly correlated methods [PDF]

open access: yes, 2011
Explicitly correlated CCSD(T)-F12b calculations have been carried out with systematic sequences of correlation consistent basis sets to determine accurate near-equilibrium potential energy surfaces for the X<sup>2</sup>∏ and a<sup>

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.

The Electronic Structure of Short Carbon Nanotubes: The Effects of Correlation

open access: yesAdvances in Condensed Matter Physics, 2015
This paper presents a tight binding and ab initio study of finite zig-zag nanotubes of various diameters and lengths. The vertical energy spectra of such nanotubes are presented, as well as their spin multiplicities.

Beta Decay in Medium-Mass Nuclei with the In-Medium Similarity Renormalization Group

open access: yesParticles, 2021
We review the status of ab initio calculations of allowed beta decays (both Fermi and Gamow–Teller), within the framework of the valence-space in-medium similarity renormalization group approach.

Correlations between MO Eigenvectors and the Thermochemistry of Simple Organic Molecules, Related to Empirical Bond Additivity Schemes [PDF]

open access: yes, 2008
A bondingness term is further developed to aid in heat of formation (ΔfHº) calculations for C, N, O and S containing molecules. Bondingness originated from qualitative investigations into the antibonding effect in the occupied MOs of ethane.

Fabrication and ab initio study of downscaled graphene nanoelectronic devices [PDF]

open access: yes, 2012
In this paper we first present a new fabrication process of downscaled graphene nanodevices based on direct milling of graphene using an atomic-size helium ion beam. We address the issue of contamination caused by the electron-beam lithography process to

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br

open access: yesAdvanced Functional Materials, EarlyView.
Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.

Modeling the high-temperature phase coexistence region of mixed transition metal oxides from ab initio calculations

open access: yesPhysical Review Research, 2021
Accurate knowledge of phase coexistence regions, i.e., solubility gaps (SGs), is key to the development of mixed transition metal oxides for various applications, such as thermochemical energy storage, or catalysis.
