Regioselective C‐H Thio‐ and Selenocyanation of Pyrazolo[1,5‐a]pyrimidines

open access: yesChemistry – An Asian Journal, EarlyView.
A metal‐free, N‐chlorosuccinimide (NCS) mediated, highly efficient, and regioselective C−H thiocyanation and C−H selenocyanation of pyrazolo[1,5‐a]pyrimidines are achieved under mild reaction conditions for the synthesis of a wide variety of 3‐thiocyanato‐ and 3‐selenocyanatopyrazolo[1,5‐a]pyrimidines in good to excellent yield up to 99 %.

Investigation of Aggregation Induced Emission Mechanism of Tetrabenzoheptafulvalene Derivative by Spin‐Flip Time‐Dependent Density Functional Theory (SF‐TDDFT)

open access: yesChemistry – An Asian Journal, EarlyView.
The SF‐TDDFT study of 10,10′,11,11′‐tetrahydro‐5,5′‐bidibenzo[a,d][7]annulenylidene (a tetrabenzoheptafulvalene derivative, abbreviated as THBDBA) in THF solution reveals the cause of its AIE behavior, While in solution intramolecular vibration leads to conical intersection between S0 and S1 states (i.

The presence of superoxide ions and related dioxygen species in zinc oxide—A structural characterization by in situ Raman spectroscopy

open access: yesJournal of Raman Spectroscopy, Volume 53, Issue 12, Page 2137-2146, December 2022., 2022
The Raman spectra of zinc oxide powder and single crystals as well as of ZnO films support the presence of the yellow superoxide ion O2− by the band at ~1140 cm−1. Additionally, the band at ~1560 cm−1 identify the O2‐molecule inside the deposited films and in pressed powders.

Environmental Sustainability and Business Profitability: Profiling Winners and Losers With Machine Learning

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT We utilize a rich dataset of manufacturing firms to investigate the heterogeneous effects of ISO 14001 on the financial performance of certified firms. We employ machine learning techniques, specifically causal tree and causal forest, to uncover these effects. Our findings reveal consistently positive average effects of ISO 14001 certification

Determining the best fitting distribution of annual precipitation data in Serbia using L-moments method [PDF]

open access: yesarXiv, 2014
The monthly precipitation data from 29 meteorological stations for the period 1946--2012 from Serbia were used. To describe the behaviour of precipitation data at a specific location, it is necessary to identify the distribution that best fits the data. For this purpose, three distributions i.e. generalized extreme value (GEV), generalized Pareto (GPD)
