New Benzenoids from the Roots of

open access: yesNatural Product Communications, 2015
Two new benzenoids, linderagatin A and B (1–2) , were isolated from the roots of Lindera aggregata. Their structures were elucidated on the basis of 1D ( 1 H, 13 C) and 2D NMR (COSY, NOESY, HSQC and HMBC) spectra.

Retracing the molecular basis and evolutionary history of the loss of benzaldehyde emission in the genus Capsella [PDF]

open access: yes, 2019
The transition from pollinator‐mediated outbreeding to selfing has occurred many times in angiosperms. This is generally accompanied by a reduction in traits attracting pollinators, including reduced emission of floral scent.

Aroma precursors of Grignolino grapes (Vitis vinifera L.) and their modulation by vintage in a climate change scenario

open access: yesFrontiers in Plant Science, 2023
Current climatic conditions may cause significant changes in grapevine phenology and maturity dynamics linked often with changes to ecoclimatic indicators.

Tight upper bound on the maximum anti-forcing numbers of graphs

open access: yes, 2017
Let $G$ be a simple graph with a perfect matching. Deng and Zhang showed that the maximum anti-forcing number of $G$ is no more than the cyclomatic number.

A Crack‐Based One‐Dimensional Microspheres Array Enables Thermal–Mechanical Decoupled Dual‐Functional Sensing

open access: yesAdvanced Science, EarlyView.
Inspired by Nostoc, a crack‐based one‐dimensional microspheres array (COMA) sensor is developed, which stabilizes crack geometry under isotropic expansion, enabling a predictable, monotonic thermal response from which true strain can be accurately extracted. The COMA sensor exhibits high sensitivity at ultralow deformation (gauge factor up to 89) and a

On distance-based indices of regular dendrimers using automorphism group action

open access: yesMain Group Metal Chemistry, 2023
The various topological indices are helpful in predicting the bioactivity of molecular compounds in quantitative structure–activity relationship/quantitative structure–property relationship study. The Balaban index and Harary index are the distance-based

Uthrene, a radically new molecule? [PDF]

open access: yes, 2015
We have studied uthrene with a large range of quantum chemical models. Uthrene is predicted to be naturally twisted and to possess a triplet ground state, making it the smallest non-planar polycyclic biradical that can be derived from graphene.The ...

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Automated conjecturing VI : domination number of benzenoids [PDF]

open access: yes, 2018
We demonstrate the use of a conjecturing program that can be a tool for researchers investigating bounds of invariants of chemical graphs by investigating upper bounds for the domination number of a benzenoid.

Metric and Fault-Tolerant Metric Dimension of Hollow Coronoid

open access: yesIEEE Access, 2021
Coronoid systems actually arrangements of hexagons into six sides of benzenoids. By nature, it is an organic chemical structure. Hollow coronoids are primitive and catacondensed coronoids. It is also known as polycyclic conjugated hydrocarbons.
