Highly efficient eco-friendly corrosion inhibitor for mild steel in 5 M HCl at elevated temperatures: experimental & molecular dynamics study
(
Nature Publishing Group
, 2019 , Article)
Laurhydrazide N?-propan-3-one was used as an eco-friendly inhibitor for the corrosion of mild steel in 5 M HCl at elevated temperatures. Various electrochemical techniques and surface characterization methods were utilized ...
Natural aging of shape stabilized phase change materials based on paraffin wax
(
Elsevier Ltd
, 2017 , Article)
Natural aging of shape-stabilized phase change materials containing linear low density polyethylene (LLDPE), paraffin wax and expanded graphite (EG) in Qatari climate has been studied. It was found that expanded graphite ...
One-pot microwave-assisted green synthesis of amine-functionalized graphene quantum dots for high visible light photocatalytic application
(
Elsevier Masson SAS
, 2019 , Article)
Nowadays, graphene quantum dots (GQDs) have gained a huge interest in the field of visible-range photocatalysts because of their tunable band gap and stable photochemical properties. In this work, amine-functionalized GQDs ...
Electrically conductive electrospun polymeric mats for sensing dispersed vegetable oil impurities inwastewater
(
MDPI AG
, 2019 , Article)
This paper addresses the preparation of electrically conductive electrospun mats on a base of styrene-isoprene-styrene copolymer (SIS) and multiwall carbon nanotubes (CNTs) and their application as active sensing elements ...
The ramsey number for theta graph versus a clique of order three and four
(
University of Zielona Gora
, 2014 , Article)
For any two graphs F1 and F2, the graph Ramsey number r(F1, F2) is
the smallest positive integer N with the property that every graph on at
least N vertices contains F1 or its complement contains F2 as a subgraph.
In ...
TiO2 nanotubes and mesoporous silica as containers in self-healing epoxy coatings
(
Nature Publishing Group
, 2016 , Article)
The potential of inorganic nanomaterials as reservoirs for healing agents is presented here. Mesoporous silica (SBA-15) and TiO2 nanotubes (TNTs) were synthesized. Both epoxy-encapsulated TiO2 nanotubes and amine-immobilized ...
Edge Maximal C2k+1-edge Disjoint Free Graphs
(
University of Zielona Gora
, 2012 , Article)
For two positive integers r and s, G(n;r,s) denotes to the class of graphs on n vertices containing no r of s-edge disjoint cycles and f(n;r,s) = max{E(G):G ∈ G(n;r,s)}. In this paper, for integers r ≥ 2 and k ≥ 1, we ...
Mesoporous TiO2 Mesocrystals: Remarkable Defects-Induced Crystallite-Interface Reactivity and Their in Situ Conversion to Single Crystals
(
American Chemical Society
, 2015 , Article)
Oriented self-assembly between inorganic nanocrystals and surfactants is emerging as a route for obtaining new mesocrystalline semiconductors. However, the actual synthesis of mesoporous semiconductor mesocrystals with ...
On minimum cycle bases of the wreath product of wheels with stars
(
Zenodo
, 2010 , Article)
The length of a cycle basis of a graph is the sum of the lengths of its elements. A minimum cycle basis is a cycle basis with minimum length. In this work, a construction of a minimum cycle basis for the wreath product of ...
Synthesis, characterization, and antimicrobial properties of novel double layer nanocomposite electrospun fibers for wound dressing applications
(
Dove Press
, 2017 , Article)
Herein, novel hybrid nanomaterials were developed for wound dressing applications with antimicrobial properties. Electrospinning was used to fabricate a double layer nanocomposite nanofibrous mat consisting of an upper ...
