Quantum-Size Effects in Ultra-Thin Gold Films on Pt(111) Surface
(MDPI, 2023-12-22)
We calculate, within the density-functional theory, the atomic and electronic structure of the clean Pt(111) and Au(111) surfaces and the nML-Au/Pt(111) systems with n varying from one to three. The effect of the spin–orbital ...
A multimodel analysis of post-Glasgow climate targets and feasibility challenges
(Nature Climate Change, 2023-06-01)
The COP26 Glasgow process resulted in many countries strengthening their 2030 emissions reduction targets and announcing net-zero pledges for 2050–2070 but it is not clear how this would impact future warming. Here, we use ...
Indirect interactions between pollinators drive interaction rewiring through space
(Ecosphere, 2023-06-01)
In recent years, an extended body of literature has focused on the importance of either temporal or spatial dynamics in shaping the structure of interacting plant and pollinator communities. This improvement from a previously ...
Disentangling the Role of Forest Structure and Functional Traits in the Thermal Balance of the Mediterranean–Temperate Ecotone
(Journal of Geophysical Research: Biogeosciences, 2023-06-01)
The thermal balance of forests is the result of complex land–atmosphere interactions. Different climate regimes and plant functional types can have contrasting energy budgets, but little is known about the influence of ...
Additive Manufacturing of Fe-Mn-Si-Based Shape Memory Alloys: State of the Art, Challenges and Opportunities
(MDPI, 2023-12-05)
Additive manufacturing (AM) constitutes the new paradigm in materials processing and its use on metals and alloys opens new unforeseen possibilities, but is facing several challenges regarding the design of the microstructure, ...
Altered Red Blood Cell Fatty Acid and Serum Adipokine Profiles in Subjects with Obesity
(MDPI, 2023-12-15)
Background: Adipokines, as well as the fatty acid profile of red blood cell (RBC) membranes, are known to play important roles in the development and progression of metabolic complications induced by obesity. Thus, the ...
4D Printing: The Development of Responsive Materials Using 3D-Printing Technology
(MDPI, 2023-12-07)
Additive manufacturing, widely known as 3D printing, has revolutionized the production of biomaterials. While conventional 3D-printed structures are perceived as static, 4D printing introduces the ability to fabricate ...
Evaluation of the Thermal Performance of Two Passive Facade System Solutions for Sustainable Development
(MDPI, 2023-12-11)
Sustainable development is essential for the future of the planet. Using passive elements, like ventilated facades based on insulation and air chambers, or living walls, which are solutions based on nature, is a powerful ...
Experimental Investigations of Using Aluminum Oxide (Al2O3) and Nano-Graphene Powder in the Electrical Discharge Machining of Titanium Alloy
(MDPI, 2023-12-16)
In the present study, a comprehensive parametric analysis was carried out using the electrical discharge machining of Ti6Al4V, using pulse-on time, current, and pulse-off time as input factors with output measures of surface ...
Flipped Learning in Higher Education for the Development of Intrinsic Motivation: A Systematic Review
(MDPI, 2023-12-11)
Background: Flipped learning (FL) is being considered, in terms of new educational trends, a beneficial pedagogical model in the classroom. In particular, FL and intrinsic motivation (IM) are key components to the model ...
