Influence of chain topology (cyclic versus linear) on the nucleation and isothermal crystallization of poly(L-lactide) and poly(D-lactide)
(American Chemical Society, 2018-02-20)
In this paper, ring closure click chemistry methods have been used to produce cyclic c-PLLA and c-PDLA of a number average molecular weight close to 10 kg/mol. The effects of stereochemistry of the polymer chains and their ...
Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)
Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ...
Mean Stress Effect on the Axial Fatigue Strength of DIN 34CrNiMo6 Quenched and Tempered Steel
(MDPI, 2018-04)
The present study consists of a theoretical and experimental investigation of the effect of axial mean stresses on the high cycle fatigue behaviour of DIN 34CrNiMo6 high strength steel in quenched and tempered conditions. ...
Secure Protocol and IP Core for Configuration of Networking Hardware IPs in the Smart Grid
(MDPI, 2018-03)
Nowadays, the incorporation and constant evolution of communication networks in the electricity sector have given rise to the so-called Smart Grid, which is why it is necessary to have devices that are capable of managing ...
Optimizing Biodiesel Production from Waste Cooking Oil Using Genetic Algorithm-Based Support Vector Machines
(MDPI, 2018-11-01)
The ever increasing fuel demands and the limitations of oil reserves have motivated research of renewable and sustainable energy resources to replace, even partially, fossil fuels, which are having a serious environmental ...
Identification of a panel of serum protein markers in early stage of sepsis and its validation in a cohort of patients
(Elsevier, 2018-08)
Background: Sepsis is a life-threatening illness with a challenging diagnosis. Current serum biomarkers are not sensitive enough for diagnosis. With the aim of finding proteins associated with sepsis, serum protein profile ...
3-Form Cosmology: Phantom Behaviour, Singularities and Interactions
(MDPI, 2018-03-03)
The latest cosmological observations by the Planck collaboration (and combined with others) are compatible with a phantom-like behaviour (w <-1) for the dark energy equation of state that drives the current acceleration ...
Observation of an Excited Omega(-) Baryon
(American Physical Society, 2018-08-02)
Using data recorded with the Belle detector, we observe a new excited hyperon, an Omega*(-) candidate decaying into Xi K-0(-) and Xi K--(S)0 with a mass of 2012.4 +/- 0.7(stat) +/- 0.6(syst) McV/c(2) and a width of Gamma ...
University Social Responsibility towards Engineering Undergraduates: The Effect of Methodology on a Service-Learning Experience
(MDPI, 2018-06)
Service-Learning (SL) experiences enable University Social Responsibility (USR) to be worked on in engineering studies as a core of education for Sustainability. The combined use of such experiences with active student-centered ...
Analysis of the Process Parameter Influence in Laser Cladding of 316L Stainless Steel
(MDPI, 2018-09)
Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to ...
