Density functional theory (DFT) and ab initio methods are used to investigate the interaction of one, two and three hydrogen molecules with Li+-doped benzene, a model for lithium-doped carbon-based and metal organic framework materials. MO5-2X is found to be the best DFT method considered, reproducing MP2 and CCSD(T)H-2 binding energies to Li+-doped benzene. The MO5-2X results also agree with H-2 binding energies previously obtained in an extended model of Li atom-doped MOF-5. These calculations suggest H-2 binding in Li-doped materials is, primarily, a local interaction, implying that model compounds can be used to describe these systems.

Vertical ionization potential benchmarks from Koopmans prediction of Kohn-Sham theory with long-range corrected (LC) functional*

Kimihiko Hirao, Han-Seok Bae, Jong-Won Song, Bun Chan

Summary: In this study, the Kohn-Sham density functional theory with long-range correction was used to estimate the valence ionization potentials of a group of small molecules. The results were compared with other methods, and it was found that the optimized functional performed better in estimating the valence level ionization potentials. The method was also reasonably accurate for outer valence orbitals but less accurate for core ionization energies.

Modeling the Conformational Preference of the Lignocellulose Interface and Its Interaction with Weak Acids

Bun Chan, William Dawson, Takahito Nakajima

Summary: In this study, we investigated the conformational space of the hydrogen-bonded and covalent linkages between the sugar and lignin components in lignocellulose. Through a multistage screening process, we identified a set of lowest-energy isomers and developed a cost-effective screening protocol. All low-energy conformers were characterized by hydrogen bonding between the sugar and lignin moieties. We also examined the interactions of covalently bonded sugar-lignin models with weak acids and found strong interactions with the oxygen of the sugar-O-lignin linkage. Our results suggest that acids like dihydrogen citrate could be attractive alternatives to HSO3- for lignocellulose processing.

The core ionization energies calculated by delta SCF and Slater's transition state theory

Kimihiko Hirao, Takahito Nakajima, Bun Chan, Ho-Jin Lee

Summary: The core ionization energies of second-period and third-period elements are investigated using Lambda SCF and Slater's transition state (STS) theory with Hartree-Fock (HF) and Kohn-Sham (KS) approximations. Electron correlation increases the estimated core ionization energies, while the self-interaction error (SIE) decreases them, especially for the third-period elements. HF predictions of core ionization energies are reasonably accurate due to the lack of SIE, while KS calculations are sensitive to the functional used. Overall, the study highlights the importance of considering electron correlation and SIE when predicting core ionization energies. Rating: 7 out of 10.

Optimal Small Basis Set and Geometric Counterpoise Correction for DFT Computations

Bun Chan

Summary: In this study, the performance of various small basis sets and their geometric counterpoise (gCP) corrections for DFT computations were examined. It was found that a simplified scheme, unity-gCP, using a single scaling parameter, can yield fair results for an arbitrary basis set. The optimal balance between accuracy and computational efficiency was found to be 6-31+G(2d) for medium-sized basis sets. On the other hand, less balanced basis sets, even larger ones, can show significantly worse accuracy, and the inclusion of gCP may lead to overcorrections.

Computational insights into the singlet-triplet energy gaps, ionization energies, and electron affinities for a diverse set of 812 small fullerenes (C20-C50)

Bun Chan, Amir Karton

Summary: In this study, the energy differences between singlet and triplet states of small fullerenes were investigated using density functional theory (DFT), along with the ionization energy (IE) and electron affinity (EA). The DFT methods consistently showed qualitative observations. Among the 812 fullerene isomers, approximately 80-90% had a singlet ground state, while the rest had ground-state triplets. Some of these may enhance the efficiency of singlet-fission materials for light harvesting. The triplet-singlet energy difference correlated well with the IE-EA differences, which serve as indicators for charge-transfer capabilities. Larger fullerenes were surveyed to identify candidates with superior charge-transfer properties, suggesting that optimally shaped medium-sized fullerenes are the most promising.

Efficient Photothermal Energy Conversion Triggered by near-Infrared Light in a Dithiolene-Based Metal-Organic Framework

Qinyi Gu, Zi-Han Zhao, Bun Chan, Tong Yan, Jing-Lin Zuo, Deanna M. D'Alessandro, Cheng-Hui Li

Summary: A new Ni-dithiolene ligand was used to prepare a photothermal metal-organic framework (MOF) that showed efficient conversion of light into heat. The MOF had strong absorption in the near-infrared region due to the radical monoanion of the ligands, and the structure played an important role in the photothermal properties. The photothermal MOF was then doped into a self-healing polymer, enabling the composites to recover from dynamic damage using the heat generated by photostimulus.

Charge transfer in mixed and segregated stacks of tetrathiafulvalene, tetrathianaphthalene and naphthalene diimide: a structural, spectroscopic and computational study

Chanel F. Leong, Bun Chan, Tianfu Liu, Harrison S. Moore, Idan Hod, Marcello B. Solomon, Pavel M. Usov, Joseph T. Hupp, Omar Farha, Deanna M. D'Alessandro

Summary: This article reports novel charge transfer (CT) complexes containing mixed and segregated stack donor-acceptor (D-A) complexes of tetrathiafulvalene (TTF), tetrathianaphthalene (TTN) and naphthalene diimide (NDI). Despite the detection of low charge transfer in the three salts using various spectroscopic techniques, the properties of TTN core are elucidated for the first time through DFT calculations. The article highlights the performance of TTN in a CT complex and demonstrates the importance of a combined approach to characterizing CT in organic D-A complexes.

Keiran N. Rowell, Scott H. Kable, Meredith J. T. Jordan

Summary: Carbonyls are abundant in the atmosphere and play a crucial role in atmospheric photochemistry. Experimental and theoretical studies suggest that concerted triple fragmentation and H-2 loss pathways in saturated aldehydes have direct implications for global H-2 production, while tautomerisation affects the atmospheric production of organic acids.

Complexes of the noble-gas atoms with borazine: Theoretical insights into structure, stability, and bonding character

Stefano Borocci, Armando Camerlingo, Felice Grandinetti, Maria Rutigliano, Nico Sanna

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Investigation of Ce-based buffer layers on electrochemical performance of YSZ-based symmetric solid oxide fuel cells

Chanchan Wang, Quan Yang, Yanzhi Ding, Xiaoyong Lu, Dong Tian

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
