Rapid and Effective Inactivation of SARS-CoV-2 with a Cationic Conjugated Oligomer with Visible Light: Studies of Antiviral Activity in Solutions and on Supports.

This paper presents results of a study of a new cationic oligomer that contains end groups and a chromophore affording inactivation of SARS-CoV-2 by visible light irradiation in solution or as a solid coating on paper wipes and glass fiber filtration substrates. A key finding of this study is that the cationic oligomer with a central thiophene ring and imidazolium charged groups gives outstanding performance in both the killing of bacterial cells and inactivation of the virus at very short times. Our introduction of cationic -methyl imidazolium groups enhances the light activation process for both and SARS-CoV-2 but dampens the killing of the bacteria and eliminates the inactivation of the virus in the dark.

Study on particle radiative properties of lignite, hard coal and biomass fly ashes in the infrared wavelength range.

Fly ash, which is a by-product of combustion in furnaces or boilers, is used in certain materials as an additive for waste recycling. The optical properties of fly ash and the effects on the heat transfer phenomena of materials used in engineering applications differ and depend on the kind of solid fuel and the combustion conditions. The morphological and the radiative properties of fly ash samples of Turkish lignite, biomass, and hard coal that are burned in different thermal power plants were studied herein.

Spectroscopic ellipsometry methods for brevetoxin detection.

The spectroscopic ellipsometry (SE), and attenuated internal reflection spectroscopic ellipsometry (TIRE) are promising methods in label-free biosensing applications.

Does democracy help reduce environmental degradation?

The main purpose of this study is to examine the democracy-environmental degradation nexus in 26 Organization for Economic Cooperation and Development (OECD) countries from 1990 through 2015 by using panel data estimation methods, performing well under cross-sectional dependence. Empirical results are as follows: (i) Tests show that cross-section dependence exists among panel members, and slope coefficients are heterogeneous, respectively, and (ii) long-term coefficient estimation results with Augmented Mean Group estimator show that democracy, non-renewable energy consumption, and real income per capita have statistically significant negative effects on environmental quality, whereas renewable energy consumption has a positive effect. There is also no statistically significant relationship between urbanization and environmental quality.

Psychological inflexibility mediates the relationship between fear of negative evaluation and psychological vulnerability.

College students worldwide and in Turkey face many biopsychosocial spiritual and economic issues, in part due to developmental and contextual factors. Understanding these issues and their relationship with psychological inflexibility, which is the central concept to the Acceptance and Commitment Therapy (ACT), is an unexplored gap in the literature. Therefore, the aim of the present study is to examine the mediating and moderating roles of Psychological Inflexibility (PI) in the relationship between Fear of Negative Evaluation (FNE) and Psychological Vulnerability (PV), and to set an empirical ground for developing evidence-based research and practices based on ACT.
