Effect of waste wax and chain structure on the mechanical and physical properties of polyethylene
(
Elsevier B.V.
, 2015 , Article)
The influence of adding waste wax, produced as a by-product of the low density polyethylene manufacturing process, on the thermal and mechanical properties of three types of polyethylene (PE), high-density polyethylene ...
Calmodulin Interacts and Regulates Enzyme Activity of the Mammalian Sperm Phospholipase C
(
Elsevier
, 2017 , Article)
Sperm-specific Phospholipase C zeta (PLCζ) is widely considered to be the sole, physiological stimulus responsible for the generation of Ca2+ oscillations that induce egg activation and early embryo development during ...
A case report from Nepalese community pharmacy on levofloxacin induced severe abdominal pain
(
Elsevier
, 2013 , Article)
A 46-year-old female patient developed severe abdominal pain shortly after taking levofloxacin, 1000mg for acute bacterial sinusitis. The pain started after taking the first dose of levofloxacin and became worse after the ...
Bentonite-decorated calix [4] arene: A new, promising hybrid material for heavy-metal removal
(
Elsevier
, 2018 , Article)
There is global concern about the contamination of ground, river, and tap waters as well as soil contamination with heavy metal ions; these chemical species are known to not degrade and to cause severe health problems if ...
Generation of photo charge in poly(ethyleneimine)-TiO2-anthocyanin modified papers conditioned at different humidities.
(
Elsevier
, 2018 , Article)
The article describes the influence of humidity on the surface photodielectric properties of papers prepared from poly(ethyleneimine)-TiO2 nanoparticles-anthocyanin modified cellulose fibres. The anthocyanins were extracted ...
Development of multifunctional nano/ultrafiltration membrane based on a chitosan thin film on alginate electrospun nanofibers.
(
Elsevier
, 2017 , Article)
The aim of this study was to develop a high flux three-tier composite membrane composed of a coating
layer based on chitosan and chitosan with silver nanoparticles, electrospun alginate nanofibres as a
midlayer and ...
Effect of halloysite nano tubes on the thermal degradation behaviour of PCL/PLA microfibrillar composites
(
Elsevier
, 2017 , Article)
This paper reports on the thermal degradation behaviour and kinetics of halloysite nanotubes containing microfibrillated poly(ε-caprolactone) (PCL)/poly(lactic acid) (PLA) blends. It was found that the nanotubes probably ...
Preparation and characterisation of Ce:YAG -polycarbonate composites for white LED.
(
Elsevier
, 2016 , Article)
Ce:YAG-polycarbonate composites were prepared with several amounts of Ce:YAG in the range 0.1
e5 wt.% by using melt compounding. The structure and morphology of the composites were investigated by means of X-ray diffractometry ...
Thermal and mechanical properties of PP/HDPE/wood powder and MAPP/HDPE/wood powder polymer blend composites.
(
Elsevier
, 2017 , Article)
The morphology and properties of blends of PP/HDPE and MAPP/HDPE blends, and their composites with wood
powder, were investigated in this paper. The blends showed two-phase morphologies, and MAPP interacted
better than ...
Shear wave propagation in layered composites with degraded matrices at locations of imperfect bonding.
(
Elsevier
, 2018 , Article)
Biodegradable polymers find an increasing number of applications in different fields of engineering and medicine due to their environmental-friendly degradation. The process of degradation of biodegradable polymer constituents ...
