Semiconducting cobalt oxide nanocatalyst obtained through an eco-friendly thermal decomposition
(Elsevier, 2023)
The combination of an intense absorption of visible light and p-type semiconducting nature makes spinel cobalt oxide (Co3O4) a very attractive material for various optoelectronic applications. However, the traditional ...
Lignin based microspheres for effective dyes removal: Design, synthesis and adsorption mechanism supported with theoretical study
(Elsevier, 2023)
Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological ...
Generalized scalar equilibrium problem with applications to best and coupled best approximations
(SPRINGER Basel AG, Basel, 2017)
In this paper, we present a new theorem on the existence of solutions for a three-function scalar equilibrium problem. Compactness is expressed in terms of the existence of feasibility sets of arbitrarily small measures ...
Conditions of regularity in cone metric spaces
(Elsevier Science Inc, New York, 2011)
In this paper we prove some fixed points results on cone metric spaces for maps satisfying general contractive type conditions. Among other things, we extend some results of Nguyen [11] from metric spaces to cone metric ...
Optimization of energy consumption in buildings with hydronic heating systems considering thermal comfort by use of computer-based tools
(Elsevier Science Sa, Lausanne, 2007)
The paper deals with an optimization of parameters, which influence the energy and investment cost as well as the thermal comfort. The parameters considered in this study are: the insulation thickness of the building ...
Numerical Analysis of NOx Control by Combustion Modifications in Pulverized Coal Utility Boiler
(Amer Chemical Soc, Washington, 2012)
Considerable research efforts focus on modeling NOx formation/destruction and predicting NOx emission so that it can be controlled. A motivation for this numerical study was to examine the efficiency of combustion modifications ...
Bucket wheel excavator Integrity assessment of the bucket wheel boom tie-rod welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of ...
Structure and enhanced antimicrobial activity of mechanically activated nano TiO2
(Wiley, Hoboken, 2019)
Titanium dioxide is a photocatalyst, known not only for its ability to oxidize organic contaminants, but also for its antimicrobial properties. In this article, significant enhancement of the antimicrobial activity of TiO2 ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
