La inversión en renta fija. Una clarificación del riesgo que supone su adquisición
(Area Innovación & Desarrollo, 2021-02)
[Resumen] La renta fija tiende a ser asociada con un activo libre de riesgo y cuya rentabilidad es conocida de antemano. Pese a ello, no debe identificarse a la renta fija con estas cualidades, al igual que tampoco debe ...
Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃]
(The Royal Society of Chemistry, 2012-05)
[Abstract] We report that the hybrid organic–inorganic compound [(CH₃)₂NH₂][Mg(HCOO)₃] shows a marked dielectric transition around Tₜ ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c ...
A Logistic Approach for Kinetics of Isothermal Pyrolysis of Cellulose
(MDPI, 2021-03)
[Abstract] A kinetic model is proposed to fit isothermal thermogravimetric data obtained from cellulose in an inert atmosphere at different temperatures. The method used here to evaluate the model involves two steps: (1) ...
Dynamic rheological comparison of silicones for podiatry applications
(Elsevier, 2018-05-26)
[Abstract]: This work shows an effective methodology to evaluate the dynamic viscoelastic behavior of silicones for application in podiatry. The aim is to characterize, compare their viscoelastic properties according to ...
Crystallization kinetics of a commercial poly(lactic acid) based on characteristic crystallization time and optimal crystallization temperature
(Springer, 2020-07-23)
[Abstract]: A model is proposed to fit differential scanning calorimetry (DSC) isothermal crystallization curves obtained from the molten state at different temperatures. A commercial 3D printing polylactic acid (PLA) ...
The effect of marine ageing on the mechanical properties of a structural adhesive
(Springer, 2023)
[Abstract] The aim of this work is to study the behaviour of a structural adhesive in an aggressive setting such as the marine environment. For this purpose, an ageing procedure is carried out under marine environmental ...
Thermal and rheological comparison of adhesives
(Springer, 2019-10-10)
[Abstract]: In some industrial sectors such as naval construction, the use of adhesives is still limited to some specific applications. However, shipbuilders, academia and classification societies are cooperating to expand ...
Fillers and methods to improve the effective (out-plane) thermal conductivity of polymeric thermal interface materials – A review
(Elsevier, 2024-02-15)
[Abstract]: The internet of things and growing demand for smaller and more advanced devices has created
the problem of high heat production in electronic equipment, which greatly reduces the work
performance and life of ...
Structure and thermal property relationships in the thermomaterial di-n-butylammonium tetrafluoroborate for multipurpose cooling and cold-storage
(Royal Society of Chemistry, 2023-11-07)
[Abstract]: Nowadays around 46% of food production around the world requires refrigeration, which is generally
provided either by active vapour-compression (based on refrigerants with liquid–gas transitions) or
passive ...
El papel de los mercados alternativos como herramientas que favorecen la financiación de las pymes y su sostenibilidad
(Universidad Nacional Abierta y a Distancia UNAD de Colombia, 2021)
[Resumen] Las pequeñas y medianas empresas (pymes) tienen mayores dificultades que las grandes para obtener financiación, lo cual afecta su capacidad de crecimiento y sostenibilidad. En este contexto, surgen los mercados ...
