Predi-XY: A Python Program for Automated Generation of NICS-XY-Scans Based on an Additivity Scheme [PDF]

open access: yes, 2020
We detail the development of a new Python-based program for automatic generation of NICS-XY-Scans of cata-condensed polycyclic aromatic systems. The program uses an underlying additivity scheme, which enables generation of the Scans using only smaller ...

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

open access: yesChemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...

Sensitivity study of energy transfer between mesoscale eddies and wind-induced near-inertial oscillations [PDF]

open access: yesOcean Science
Analyses of current observations and numerical simulations at two moorings in the northern South China Sea reveal the transfer of near-inertial energy between the background currents associated with mesoscale eddies and near-inertial currents (NICs).

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

open access: yesChemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Root lodging is a physical stress that changes gene expression from sucrose accumulation to degradation in sorghum

open access: yesBMC Plant Biology, 2018
Background Sorghum (Sorghum bicolor L.) is used as a raw material for biofuels because it accumulates sugars at high levels in the stem. Lodging of sorghum occurs when the soil is wet and very high winds blow across the field.

Trade and Structural Interdependence Between the U.S. and the NICs [PDF]

open access: yes
During the decade since 1973, the U.S. economy has become increasingly interdependent with the newly industrializing countries (NICs) among the developing countries.

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons

open access: yesChemistry – A European Journal, EarlyView.
Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...

A Simple Method for the Assessment of Fusarium Head Blight Resistance in Korean Wheat Seedlings Inoculated with Fusarium graminearum

open access: yesThe Plant Pathology Journal, 2014
Fusarium head blight (FHB; scab) caused mainly by Fusarium graminearum is a devastating disease of wheat and barley around the world. FHB causes yield reductions and contamination of grain with trichothecene mycotoxins such as deoxynivalenol (DON) which ...

The OPEC Surplus and U.S.-LDC Trade [PDF]

open access: yes
This paper explores the connections between the shift of world saving toward OPEC and the changing structure of U.S. trade with the non-oil developing countries. The basic point of the paper is that during the 1970s the U.S.

Hidden in Plain Sight: Aromaticity of Hexagonal Boron Nitride

open access: yesChemistry – A European Journal, EarlyView.
How apt is the nickname “white graphene” for hexagonal boron nitride (hBN)? Although graphene's aromaticity is well established, it is not known if hBN is aromatic. In this work, hBN's aromaticity is probed using magnetic and energetic criteria. Group‐theoretic considerations and magnetically induced current density maps are used to further reveal the ...
