Integrated policy assessment and optimisation over multiple sustainable development goals in Eastern Africa
(IOP, 2019-08-20)
Heavy reliance on traditional biomass for household energy in eastern Africa has significant negative health and environmental impacts. The African context for energy access is rather different from historical experiences ...
The Effect of Titanium Dioxide Surface Modification on the Dispersion, Morphology, and Mechanical Properties of Recycled PP/PET/TiO2 PBNANOs
(MDPI, 2019-10-16)
Titanium dioxide (TiO2) nanoparticles have recently appeared in PET waste because of the introduction of opaque PET bottles. We prepare polymer blend nanocomposites (PBNANOs) by adding hydrophilic (hphi), hydrophobic (hpho), ...
Understanding Multicellularity: The Functional Organization of the Intercellular Space
(Frontiers Media, 2019-09-18)
The aim of this paper is to provide a theoretical framework to understand how multicellular systems realize functionally integrated physiological entities by organizing their intercellular space. From a perspective centered ...
Improved Thermal Insulating Properties of Renewable Polyol Based Polyurethane Foams Reinforced with Chicken Feathers
(MDPI, 2019-12-03)
In the present work, sustainable rigid polyurethane foams (RPUF) reinforced with chicken
feathers (CF) were prepared and characterized. The bio-based polyol used to formulate the foams
was obtained from castor oil. This ...
Noncollinearity in dijet fragmentation in electron-positron scattering
(American Physical Society, 2019-08-09)
We study fragmentation in electron-positron annihilation assuming a dijet situation, using variables defined independent of any frame. In a collinear situation some of the variables are centered around zero with the small ...
Real-Time Propagation TDDFT and Density Analysis for Exciton Coupling Calculations in Large Systems
(American Chemical Society, 2019-06)
Photoactive systems are characterized by their capacity to absorb the energy of light and transform it. Usually, more than one chromophore is involved in the light absorption and excitation transport processes in complex ...
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
(Nature, 2019-07-29)
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in ...
The origin of memory effects in the crystallization of polyamides: Role of hydrogen bonding
(Elsevier, 2019-12-23)
The effect of hydrogen bonding stability on the memory effects in the crystallization of long chain polyamides have been investigated by the self-nucleation calorimetric technique. Self-nucleation is characterized by three ...
Association of Maternal Iodine Status With Child IQ: A Meta-Analysis of Individual Participant Data
(Endocrine Society, 2019-03-28)
Context: Although the consequences of severe iodine deficiency are beyond doubt, the effects of mild to moderate iodine deficiency in pregnancy on child neurodevelopment are less well established.
Objective: To study the ...
The influence of the shape of Au nanoparticles on the catalyticcurrent of fructose dehydrogenase
(Springer, 2019-11)
Graphite electrodes were modified with triangular (AuNTrs) or spherical (AuNPs) nanoparticles and further modified with fructose dehydrogenase (FDH). The present study reports the effect of the shape of these nanoparticles ...
