superior conductivity, some of 2D materials can function as the electrode to realize efficient charge collection [59,60]. Moreover, 2D materials possess excellent chemical and mechanical stability with high compactness, which render them resistant to moisture, oxygen, ion migration, and metal diffusion...

Melatonin decrease - the turning point of human evolution? Explanations of "what makes us human" often include a bridge between culture and biology [51]. Recently, it has been suggested that decreased circulating melatonin levels due to light from campfires extending the day, "changed the timetab...
This is also an important point to keep in mind when space borne remote sensing precipitation products (e.g., GPM IMERG [46]) are used to obtain information about precipitation in areas that lack sufficient ground observations, such as the Tropical Andes. Even though the spatial and temporal ...
between successful and unsuccessful dieters [59]. Three brief questions are used to assess whether respondents find it easy to watch their weight, lose weight, or find it challenging to stay in shape. The items are scored on a 7-point Likert scale, with the last item being reversed coded....
This has become a focal research point, largely because there are other materials that could improve the cell performance but are expensive and usually have a detrimental effect on the parameters of the PEMFC. #5 Anion exchange membrane fuel cell: These areas of research are geared toward ...
(accessed on 29 November 2021)) was used as the initial field of HYSPLIT model, and the main campus of Lanzhou University (103.854°E, 36.047°N) was taken as the end point of the backward trajectory, with initial altitudes of 500 m (lower layer), 1500 m (middle layer), and 3000 m...
0% methanol at 50 °C for 5 min. These optimal conditions were applied to achieve the best extraction of sugars and organic acids (Table 4). The different sugars and organic acids found in aronia were quantitatively determined. It is noteworthy to point out that the content level of these ...
The aim of this research was to design and simulate an efficient and high-capacity dehydrator that optimizes drying process and minimizes energy usage. 2. Materials and Methods The work was conducted at the Universidad Autónoma de Querétaro, Amazcala campus, located in Amazcala, El Marqués, ...
