The Structure of the Free Volume in Poly(styrene-co-acrylonitrile) from Positron Lifetime and Pressure Volume Temperature (PVT) Experiments حسب Dlubek, Gunter

"…The mean hole volume, vh, varies in PS between 105 Å3 (27 °C) and 220 Å3 (190 °C), and shows a systematic decrease with increasing AN content, at Tg from 121 Å3 for PS to 102 (±2) Å3 for SAN50. …"

Food shopping, preparation and consumption practices in times of COVID-19: case of Lebanon حسب Ben Hassen, Tarek

"…Indeed, the study outcomes suggested (1) a move toward healthier diets; (2) a rise in the consumption of domestic products due to food safety concerns; (3) a change in the grocery shopping behaviors (with a rise in online shopping); (4) a surge of food stockpiling; and (5) a decrease in household food wastage. Surprisingly, COVID-19 seems to generate several positive changes toward more sustainable and healthier consumption patterns in Lebanon. …"

Food purchase and eating behavior during the COVID-19 pandemic: A cross-sectional survey of Russian adults حسب Ben Hassen, Tarek

"…Indeed, the survey results suggested (i) a change in the modality of acquiring food, consumers reduced the number of shopping trips and buying more on each trip to minimize store visits; (ii) a surge of stockpiling of non-perishable food items; (iii) a shift toward healthier diets; (iv) an increase in culinary capabilities; (v) a decrease of food waste. The results are expected to inform current emergency plans as well as long-term food-related strategies in Russia.…"

Influence of the heteroatom on the optoelectronic properties and transistor performance of soluble thiophene-, selenophene- and tellurophene-vinylene copolymers حسب Al-Hashimi, Mohammed

"…The optical band gap of the polymers is shown to systematically decrease as the size of the heteroatom is increased, mainly as a result of a stabilization of the LUMO energy, resulting in a small band gap of 1.4 eV for P3TeV. …"

Channel Network Control on Seasonal Lake Area Dynamics in Arctic Deltas حسب Tejedor, Alejandro

"…We find that monthly shrinkage rates have a pronounced structured variability around the channel network with the shrinkage rate systematically decreasing farther away from the channels. This pattern of shrinkage is predominantly attributed to a deeper active layer enhancing near-surface connectivity and storage and greater vegetation density closer to the channels leading to increased evapotranspiration rates. …"
