Thermo-rheological effects on succesful 3D printing of biodegradable polyesters
(Elsevier, 2020-06-23)
Biodegradable polybutylene succinate (PBS) and poly (butylene succinate-ran-adipate) (PBSA) were characterized to find the thermo-rheological bases for 3D printing by Fused Filament Fabrication (FFF). In dynamic viscoelastic ...
Fractionated crystallization in semicrystalline polymers
(Elsevier, 2021-02-16)
The crystallization of heterogeneously nucleated bulk polymers typically occurs in a single exothermic process, within a narrow temperature range, i.e., a single exothermic peak is detected by Differential Scanning Calorimetry ...
Direct Identification of Three Crystalline Phases in PEO-b-PCL-b-PLLA Triblock Terpolymer by In Situ Hot-Stage Atomic Force Microscopy
(Elsevier, 2020-08-04)
In this work, we provide a detailed description of the tri-lamellar nanoscale morphology of a triple crystalline PEO-b-PCL-b-PLLA triblock terpolymer obtained by Hot-Stage Atomic Force microscopy (AFM) imaging and Wide ...
Probing the role of grain boundaries in single Cu nanoparticle oxidation by in situ plasmonic scattering
(American Physical Society, 2022-04-15)
Grain boundaries determine physical properties of bulk materials including ductility, diffusivity, and electrical conductivity. However, the role of grain boundaries in nanostructures and nanoparticles is much less understood, ...
Targeting mTOR as a Therapeutic Approach in Medulloblastoma
(MDPI, 2018-07)
Mechanistic target of rapamycin (mTOR) is a master signaling pathway that regulates organismal growth and homeostasis, because of its implication in protein and lipid synthesis, and in the control of the cell cycle and the ...
Actin- regulated Siglec- 1 nanoclustering influences HIV-1 capture and virus- containing compartment formation in dendritic cells
(eLife Sciences, 2023-03)
The immunoglobulin-like lectin receptor CD169 (Siglec-1) mediates the capture of
HIV- 1 by activated dendritic cells (DCs) through binding to sialylated ligands. These interactions
result in a more efficient virus capture ...
Redox regulation of KV7 channels through EF3 hand of calmodulin
(eLife Sciences, 2023-01)
Neuronal KV7 channels, important regulators of cell excitability, are among the most sensitive proteins to reactive oxygen species. The S2S3 linker of the voltage sensor was reported as a site-mediating redox modulation ...
Fieldwork ‘headaches’. comparing feminist peace and conflict research in Kosovo and the DRC
(Universidad Autónoma de Barcelona, 2022)
This paper aims to reflect upon the principal difficulties, challenges or ‘headaches’
that doing feminist research in conflict and post-conflict contexts can involve.
Each of the authors has conducted a very different ...
Existence and stability results for a coupled system of impulsive fractional differential equations with Hadamard fractional derivatives
(AIMS Press, 2023-01)
The purpose of this study is to give some findings on the existence, uniqueness, and Hyers-Ulam stability of the solution of an implicit coupled system of impulsive fractional differential equations possessing a fractional ...
Fixed point approach to the Mittag-Leffler kernel-related fractional differential equations
(AIMS Press, 2023-02)
The goal of this paper is to present a new class of contraction mappings, so-called -contractions. Also, in the context of partially ordered metric spaces, some coupled fixed-point results for -contraction mappings are ...
