Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Drivers’ estimation of their travelling speed: a study on an expressway and a local road
(
Taylor and Francis Ltd.
, 2019 , Article)
Correctly estimating the travelling speed is essential for safety on the roads to ensure safer interactions with other drivers and to avoid violations of traffic regulations. Therefore, it is important to create understanding ...
Microstructure, wear and corrosion characteristics of Cu matrix reinforced SiC–graphite hybrid composites
(
SAGE Publications Ltd
, 2019 , Article)
The aim of the present study is to investigate the effect of SiC-graphite reinforcement on the properties of pure copper. Copper matrix composites with SiC-graphite reinforcement (0, 2.5,5, 7.5 and 10 wt.%) were prepared ...
Enhancement of CO2 biofixation and lipid production by Chlorella vulgaris using coloured polypropylene film
(
Taylor and Francis Ltd.
, 2019 , Article)
Chlorella vulgaris was cultivated with light at different wavelengths (λmax) and irradiation intensities (I) by applying a coloured tape (CT) as a simple, inexpensive light filter. C. vulgaris was cultivated in a standard ...
Surface Modified Zinc Oxide Nanoparticles as Smart UV Sensors
(
Springer New York LLC
, 2019 , Article)
The present paper examines the synthesis of ZnO nanoparticles and their surface modification via the microwave assisted sonochemical method along with its successful application in designing a smart UV sensor. The structure ...
Translating advances in organ-on-a-chip technology for supporting organs
(
John Wiley and Sons Inc.
, 2019 , Article Review)
Organ‐on‐a‐chip platforms have recently seen tremendous progress. They have found potential applications in the study of physiology and pathology of tissues, drug toxicity, and development of tissue models for replacement ...
2D Ruddlesden–Popper Perovskites for Optoelectronics
(
Wiley-VCH Verlag
, 2018 , Article Review)
Conventional 3D organic–inorganic halide perovskites have recently undergone unprecedented rapid development. Yet, their inherent instabilities over moisture, light, and heat remain a crucial challenge prior to the realization ...
Organic Thin-Film Capacitive and Resistive Humidity Sensors: A Focus Review
(
Wiley-VCH Verlag
, 2018 , Article Review)
In this paper, organic-based capacitive and resistive humidity sensors, starting from the fundamental working principles, designs, and characterization, are reviewed. The prevalent adoptions of recent technology in the ...
Concretizing green growth and sustainable business models in the water sector of Jordan
(
MDPI AG
, 2019 , Article)
The green growth paradigm has gained much attention from various governments worldwide as a guiding strategy for national and sectoral growth strategies. There is, however, little knowledge on how to integrate green growth ...
Novel electrodeposited Ni-B/Y 2 O 3 composite coatings with improved properties
(
MDPI AG
, 2017 , Article)
Ni-B/Y 2 O 3 composite coatings were developed through an electrodeposition process to study the effect of addition of Y 2 O 3 particles on structure, surface, thermal, mechanical, and anticorrosion properties of Ni-B ...
