Influence of the support on Ni catalysts performance in the in-line steam reforming of biomass fast pyrolysis derived volatiles
(Elsevier, 2018-02-06)
The influence the support has on the performance of Ni catalysts used in the reforming of biomass fast pyrolysis volatiles has been assessed. Accordingly, five catalysts have been prepared by wet impregnation method, namely ...
Insight into the deactivation and regeneration of HZSM-5 zeolite catalysts in the conversion of dimethyl ether to olefins
(ACS, 2018-09-19)
The impact of different process variables affecting the coking and rejuvenation of HZSM-5 zeolite catalyst has been studied during the conversion of dimethyl ether (DME) to olefins in a fixed bed reactor. Those variables ...
Influence of the rigid amorphous fraction and crystallinity on polylactides transport properties
(ACS, 2018-05-15)
The effect of the crystallinity and polymorphism of PLLA and PDLA-PLLA 50:50 blends on the free volume and transport properties have been studied. In the case of PDLA-PLLA 50:50 the increase on crystallinity promotes a ...
Thermal performance of sawdust and lime-mud concrete masonry units
(Elsevier, 2018-04)
Over the past three decades, growing interest in the properties of thermal envelopes and their enhancement has led to the development of new sustainable materials. Nevertheless, Concrete Masonry Units (CMUs) with negligible ...
Evaluation of chest compression artefact removal based on rhythm assessments made by clinicians
(Elsevier, 2018-01-31)
Aim
To evaluate the performance of a state-of-the-art cardiopulmonary resuscitation (CPR) artefact suppression method by assessing to what extent the filtered electrocardiogram (ECG) can be correctly diagnosed by emergency ...
Optimum Operating Conditions in Ethanol Steam Reforming over a Ni/La2O3-αAl2O3 catalyst in a Fluidized Bed Reactor
(Elsevier, 2018-01-01)
This manuscript analyzes the steam reforming of ethanol (SRE) over a Ni/La2O3-Al2O3 catalyst in a fluidized bed reactor under a wide range of operating conditions (500-650 ºC, space time up to 0.35 gcatalysth/gEtOH, and ...
Tracking the long-term dynamics of plant diversity in Northeast Spain with a network of volunteers and rangers
(Springer, 2018-05-01)
Scientific projects can greatly benefit from the participation of non-professionals in identifying environmental changes at a variety of spatial and temporal scales. In 2010, we launched a long-term project in Northeast ...
Tributyl citrate as an effective plasticizer for biodegradable polymers: effect of the plasticizer on the free volume, transport and mechanical properties
(Society of Chemical Industry. Wiley, 2018-06-16)
The effectiveness of tributyl citrate (TbC) as plasticizer for polylactide (PLLA) and poly(hydroxybutyrate) (PHB) was analyzed in order to improve the ductility of these polymers and make them good candidates for food ...
On the development and evolution of wear flats in microcrystalline sintered alumina grinding wheels.
(Elsevier, 2018-03-26)
Wheel wear is a critical issue for grinding process optimization. This is why it receives so much attentionboth from Academia and industry. The development of new generations of abrasive wheels requiresimproving the ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
