Ab Initio Theory of Photoemission from Graphene
(MDPI, 2021-05-03)
Angle-resolved photoemission from monolayer and bilayer graphene is studied based on an ab initio one-step theory. The outgoing photoelectron is represented by the time-reversed low energy electron diffraction (LEED) state ...
Engineered Magnetization and Exchange Stiffness in Direct-Write Co-Fe Nanoelements
(American Institute of Physics, 2021-01-11)
Media with engineered magnetization are essential building blocks in magnonics, spintronics, and superconductivity. However, the established thin film and lithographic techniques insufficiently suit the realization of ...
Moireless Correlations in ABCA Graphene
(National Academy of Sciences, 2021-01-26)
Atomically thin van der Waals materials stacked with an interlayer twist have proven to be an excellent platform toward achieving gate-tunable correlated phenomena linked to the formation of flat electronic bands. In this ...
How is silicic acid transported in plants?
(Springer, 2020-11)
Plants accumulate silicon in their tissues as amorphous silica. The form of silicon taken up by plants is silicic acid, a neutral molecule that passes through membrane channels with water. After seminal work on rice ...
Nanostructural Organization of Thin Films Prepared by Sequential Dip-Coating Deposition of Poly(Butylene Succinate), Poly(ε-Caprolactone) and Their Copolyesters (PBS-ran-PCL)
(Elsevier, 2021-06-04)
In this work, we prepare and characterize multiphasic thin films containing poly(epsilon-caprolactone), PCL, poly (butylene succinate), PBS, and a poly (butylene succinate-ran-epsilon-caprolactone) (PBS-ran-PCL) random ...
Kinetics of NH3 Desorption and Diffusion on Pt: Implications for the Ostwald Process.
(American Chemical Society, 2021-10-21)
We report accurate time-resolved measurements of NH3 desorption from Pt(111) and Pt(332) and use these results to determine elementary rate constants for desorption from steps, from (111) terrace sites and for diffusion ...
Slow Folding of a Helical Protein: Large Barriers, Strong Internal Friction, or a Shallow, Bumpy Landscape?
(American Chemical Society, 2020-10-15)
The rate at which a protein molecule folds is determined by opposing energetic and entropic contributions to the free energy that shape the folding landscape. Delineating the extent to which they impact the diffusional ...
Influence of Calcium Ion-Modified Implant Surfaces in Protein Adsorption and Implant Integration
(Springer, 2021-04-21)
Background Calcium (Ca) is a well-known element in bone metabolism and blood coagulation. Here, we investigate the link between the protein adsorption pattern and the in vivo responses of surfaces modified with calcium ...
Structure and Properties of Reactively Extruded Opaque Post-Consumer Recycled PET
(MDPI, 2021-10-14)
The recyclability of opaque PET, which contains TiO2 nanoparticles, has not been as well-studied as that of transparent PET. The objective of this work is to recycle post-consumer opaque PET through reactive extrusion with ...
Printability Study of a Conductive Polyaniline/Acrylic Formulation for 3D Printing
(MDPI, 2021-06-23)
There is need for developing novel conductive polymers for Digital Light Processing (DLP) 3D printing. In this work, photorheology, in combination with Jacobs working curves, efficaciously predict the printability of ...
