Bottom-up Fabrication and Atomic-Scale Characterization of Triply Linked, Laterally π-Extended Porphyrin Nanotapes
(Wiley, 2021-07-12)
Porphyrin nanotapes (Por NTs) are promising structures for their use as molecular wires thanks to a high degree of pi-conjugation, low HOMO-LUMO gaps, and exceptional conductance. Such structures have been prepared in ...
Search for the Dark Photon in B-0 -> A ' A ', A ' -> e(+)e(-), mu(+)mu(-), and pi(+)pi(-) decays at Belle
(Springer, 2021-04-20)
We present a search for the dark photon A in the B-0 -> A ' A ' decays, where A ' subsequently decays to e(+)e(-), mu (+)mu (-), and pi (+)pi (-). The search is performed by analyzing 772 x 10(6)BB<overbar></mml:mover> ...
Environmental Determinants of COVID 19 Transmission Across a Wide Climatic Gradient in Chile
(Nature Publishing Group, 2021-05-10)
Several studies have examined the transmission dynamics of the novel COVID-19 disease in different parts of the world. Some have reported relationships with various environmental variables, suggesting that spread of the ...
Validity and Reliability of the Self-Care Activities Screening Scale (SASS-14) During COVID-19 Lockdown
(BioMed Central, 2021-01-02)
Background In a context where there is no treatment for the current COVID-19 virus, the combination of self-care behaviours together with confinement, are strategies to decrease the risk of contagion and remain healthy. ...
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 ...
Optimizing Laser Powder Bed Fusion Parameters for IN-738LC by Response Surface Method
(MDPI, 2020-10-30)
A method to find the optimum process parameters for manufacturing nickel-based superalloy Inconel 738LC by laser powder bed fusion (LPBF) technology is presented. This material is known to form cracks during its processing ...
Effect of WEDM Process Parameters on Surface Morphology of Nitinol Shape Memory Alloy
(MDPI, 2020-11-03)
Nickel–titanium shape memory alloys (SMAs) have started becoming popular owing to their unique ability to memorize or regain their original shape from the plastically deformed condition by means of heating or magnetic or ...
Structural Characterization of the ICOS/ICOS-L Immune Complex Reveals High Molecular Mimicry by Therapeutic Antibodies
(Nature, 2020-10-08)
The inducible co-stimulator (ICOS) is a member of the CD28/B7 superfamily, and delivers a positive co-stimulatory signal to activated T cells upon binding to its ligand (ICOS-L). Dysregulation of this pathway has been ...
Evaluating the Effect of Different Base Temperatures to Calculate Degree-Days
(Sciendo, 2020-09)
Degree-days are used as a forecasting tool to predict energy demand and for normalizing energy consumption to be able to compare between different properties across different years. The base temperature is the main aspect ...
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 ...
