Synthesis and characterization of Sm3+-doped ZnO nanoparticles via a sol–gel method and their photocatalytic application
(
Springer New York LLC
, 2018 , Article)
Abstract: Spherical ZnO nanoparticles doped by samarium ions were successfully synthesized via a simple sol–gel method. The structures, morphologies, optical properties and surface areas were investigated for all samples ...
Donating Time or Money? The Effects of Religiosity and Social Capital on Civic Engagement in Qatar
(
Springer Netherlands
, 2018 , Article)
Few studies have examined the role of religiosity and social capital on civic engagement in the context of a Muslim country. In this paper, we explore the impact of religiosity and social capital on charitable donations ...
Foamy phase change materials based on linear low-density polyethylene and paraffin wax blends
(
Springer Nature
, 2018 , Article)
Foamy phase-change materials (FPCMs) based on linear low-density polyethylene (LLDPE) blended with 30 wt.% of paraffin wax (W) were successfully prepared for the first time. The advantage of these materials is their double ...
Nanoscale studies of the early stages of scale formation in sour environments
(
one petro
, 2018 , Article)
The corrosion of carbon steel in environments containing hydrogen sulfide (H2S) is a critical issue to the oil and gas industry. Although considerable research efforts have been carried out, there is not yet a complete ...
Watermarking: A review of software and hardware techniques
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Watermarking is a well-known technique traditionally used in banknotes and other documents to discourage counterfeiting. It usually consists of semi-transparent symbols embedded on paper. Similar concepts were applied to ...
Light-controllable viscoelastic properties of a photolabile carboxybetaine ester-based polymer with mucus and cellulose sulfate
(
Springer Nature
, 2018 , Article)
In this study, the interaction of a photoswitchable carboxybetaine ester-based polymer with mucus and cellulose sulfate was elucidated, showing light-controllable viscoelastic properties. This polymer contains photolabile ...

Low-density polyethylene (LDPE) and polystyrene (PS) films with hydrophilic surface were prepared by photochemical grafting of sulfobetaine-based copolymer containing photolabile moiety, and long-term stability of the ...
Effect of Trace 100 vppm H2S on the Corrosion Behaviour of Plain Carbon and Microalloyed Steels in a Predominant Sweet Environment in High Flow Regime
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
We investigate the effects of the presence of trace (100 vppm) H2S on the corrosion behaviour of plain carbon steel and its various micro-alloyed counterparts in a CO2 saturated (sweet) brine (0.5 M NaCl) environment, in ...
