Self-nucleation Effects on Polymer Crystallization
(ACS, 2020-05-28)
The existence of a “memory” of the previous crystalline state, which survives melting and enhances re-crystallization kinetics by a self-nucleation process, is well-known in polymer crystallization studies. Despite being ...
Rheology of Polymer Processing in Spain (1995–2020)
(MDPI, 2021-07-14)
The contribution of Spanish scientists to the rheology involved in polymer processing during the last 25 years is investigated. It is shown that the performed research covers, at different levels, all industrial polymeric ...
A Generic ROS-Based Control Architecture for Pest Inspection and Treatment in Greenhouses Using a Mobile Manipulator
(IEEE, 2021-07-12)
To meet the demands of a rising population greenhouses must face the challenge of producing more in a more efficient and sustainable way. Innovative mobile robotic solutions with flexible navigation and manipulation ...
Unexpected structural properties in the saturation region of the odd-even effects in aliphatic polyethers: Influence of crystallization conditions
(ACS, 2022-01-04)
A series of aliphatic polyethers with different chain lengths (nCH2= 6 to 12, and 16) is
studied employing differential scanning calorimetry and X-rays scattering. The
calorimetric and structural behavior of samples ...
Competition between Chain Extension and Crosslinking in Polyamide 1012 during High Temperature Thermal Treatments as Revealed by SSA Fractionation
(ACS, 2021-08-03)
Self-nucleation and annealing (SSA) is an efficient way to thermally fractionate semi-crystalline polymers. The thermal fractions produced by SSA have distinct melting points that correspond to different average lamellar ...
Experimental and Data Fitting Guidelines for the Determination of Polymer Crystallization Kinetics
(Springer Nature, 2022-05-05)
The crystallization kinetics of semicrystalline polymers is often studied with isothermal experiments and analyzed by fitting the data with analytical expressions of the Avrami and Lauritzen and Hoffman (LH) theories. To ...
Peculiar self-nucleation behavior of a polybutene-1/ethylene random copolymer
(Wiley, 2021-07-31)
The self-nucleation behavior of a polybutene-1/ethylene random copolymer, P(B1-ran-E), which undergoes a complex crystal-crystal transition behavior, has been studied in detail. Similar to PE random copolymers, this material ...
Melt Memory Effects in Poly(butylene succinate) Studied by Differential Fast Scanning Calorimetry
(MDPI, 2020-11-26)
It is widely accepted that melt memory effect on polymer crystallization depends on thermal history of the material, however a systematic study of the different parameters involved in the process has been neglected, so ...
Screening for genetic variants associated with Familial Hypercholesterolemia: unravelling the epigenetic mechanisms leading to statin-induced Type 2 Diabetes Mellitus
(2021-02-26)
La presente Tesis Doctoral tiene como objetivo estudiar como nuevas variantes genéticas de diversos genes inducen el desarrollo de hipercolesterolemia familiar, así como descifrar los mecanismos moleculares detrás de los ...
Aveiroko eta Zamorako zeramika ekoizpenen azterketa arkeometrikoa eta jalkitze-osteko kutsadura-eta eraldaketa-prozesuen identifikazioa
(2022-02-25)
In this Doctoral Thesis a thorough study to deepen in the archaeological knowledge about the Medievaland Post-Medieval pottery activity of the north-west of the Iberian Peninsula is carried out. In this way,the existing ...
