Measurements and Analysis of Temporal and Spatial Variability of WiFi Exposure Levels in the 2.4 GHz Frequency Band
(Elsevier, 2019-08-22)
[EN] This paper presents an evaluation of the WiFi exposure levels inside the university in the 2.4 GHz frequency band. The selected environment is the typical scenario where WiFi exposure concerns have increased in the ...
Na-Ion Batteries—Approaching Old and New Challenges
(Wiley, 2020-10-11)
The last 10 years established the beginning of a post-lithium era in the field of energy storage, with the renaissance of Na-ion batteries (NIBs) as alternative for Li-based systems. The development of this technology has ...
Effect of different aqueous synthesis parameters on the size of CdSe nanocrystals
(Springer Nature, 2012-06-30)
The variation of CdSe nanoparticle size as a function of synthesis conditions is presented. Cadmium sulphate (CdSO4), cadmium chloride (CdCl2) and sodium selenosulphate (Na2SeSO3) solutions were used as precursors. ...
Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Joint cost of energy under an optimal economic policy of hybrid power systems subject to uncertainty
(Elsevier, 2015-08-01)
Economical optimization of hybrid systems is usually performed by means of LCoE (levelized cost of energy) calculation. Previous works deal with the LCoE calculation of the whole hybrid system disregarding an important ...
Exact Learning: On the Boundary between Horn and CNF
(ACM, 2020-02-11)
A major problem in computational learning theory is whether the class of formulas in conjunctive normal
form (CNF) is efficiently learnable. Although it is known that this class cannot be polynomially learned using either ...
In Vitro Degradation of PLCL/nHA Biodegradable Scaffolds
(Taylor & Francis, 2015-04-01)
We investigated the effect of bioactive nanoparticles on the in-vitro degradation of PLCL and
PLCL/nHA composite scaffolds. The concentration of nanohydroxyapatite significantly
affected the degradation rate. An increase ...
Energy efficiency optimisation in industrial processes: Integral decision support tool
(Elsevier, 2020)
Assessing and improving energy efficiency in manufacturing processes is a crucial issue for companies who wish to become competitive. In addition, there are high margins of technical energy efficiency improvement for ...
Emerging application of a structural and chemical analyzer for the complete characterization of metal-rich particulate matter
(ACS, 2013-07-02)
Clean air is considered to be a basic requirement of human health and well-being. An increasing range of adverse health effects has been linked to air pollution, at ever-lower concentrations. This research shows the newly ...
Energetic viability of a polyolefin pyrolysis plant
(American Chemical Society, 2018-03)
The energetic viability of a polyolefin pyrolysis unit that could be installed in a refinery plant was examined. Thermal pyrolysis at 500 and 700 degrees C, and the catalytic cracking by means of HZSM-5 and HY catalysts ...
