The Oxford Handbook of International Climate Change Law. Edited by CINNAMON P CARLARNE, KEVIN R GRAY and RICHARD TARASOFSKY
(
Oxford University Press
, 2017 , Article)
The urgency of climate change necessitates considering what types of governance options are available when the existing approaches are failing.1
The United Nations Framework Climate Change Convention (UNFCCC) Secretariat’s ...
Colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films and their optical properties
(
Springer Verlag
, 2017 , Article)
In this article, we investigated the optical properties and colloidal distribution of the PCPDTBT and VOPcPhO in the organic amalgam thin films prepared by spin-coating technique. A very even dispersion of donor and acceptor ...
An efficient eco advanced oxidation process for phenol mineralization using a 2D/3D nanocomposite photocatalyst and visible light irradiations
(
Nature Publishing Group
, 2017 , Article)
Nanocomposites (CNTi) with different mass ratios of carbon nitride (C3N4) and TiO2 nanoparticles were prepared hydrothermally. Different characterization techniques were used including X-ray diffraction (XRD), UV-Vis diffuse ...
Highly efficient photocatalytic z-scheme hydrogen production over oxygen-deficient WO3-x nanorods supported Zn0.3Cd0.7S heterostructure
(
Nature Publishing Group
, 2017 , Article)
The demand for clean renewable energy is increasing due to depleting fossil fuels and environmental concerns. Photocatalytic hydrogen production through water splitting is one such promising route to meet global energy ...
The Practice of Research Ethics in Lebanon and Qatar: Perspectives of Researchers on Informed Consent
(
SAGE Publications Inc.
, 2017 , Article)
Informed consent requirements for conducting research with human participants are set by institutional review boards (IRBs) following established guidelines. Despite this, researchers continue to face challenges in seeking ...
Aggregated Molecular Fluorophores in the Ammonothermal Synthesis of Carbon Dots
(
American Chemical Society
, 2017 , Article)
Recently, molecular fluorophores were shown to be formed in the bottom-up chemical synthesis, contributing to the emission of carbon dots (CDs), derived from a citric acid precursor. We applied an ammonothermal synthesis ...
Influence of Surfactant Structure on the Stability of Water-in-Oil Emulsions under High-Temperature High-Salinity Conditions
(
Hindawi Limited
, 2017 , Article)
Emulsified water-in-oil (W/O) systems are extensively used in the oil industry for water control and acid stimulation. Emulsifiers are commonly utilized to emulsify a water-soluble material to form W/O emulsion. The selection ...
Effect of nanostructured polyhedral oligomeric silsesquioxane on the physical properties of poly(vinyl alcohol)
(
John Wiley and Sons Inc.
, 2017 , Article)
An effective amphiphilic polyhedral oligomeric silsesquioxane (POSS) encapsulated poly(vinyl alcohol) (PVA) nanocomposite was successfully fabricated by solution blending method. Anionic octa(tetramethylammonium) (Octa-TMA) ...
Microton irradiation induced tuning of dielectric properties of nano ZnO-natural rubber disks
(
Springer Verlag
, 2017 , Article)
The effect of electron beam irradiation of dielectric and conductivity properties of nano ZnO-natural rubber (NR) disks was investigated here. It is revealed that electric properties such as AC conductivity, dielectric ...
