Non-fullerene organic photovoltaics based on thienopyrroledione comprising random copolymers; effect of alkyl chains
(Elsevier, 2021)
Two new random donor-acceptor (D-A) copolymers, signed as P1 and P2, were designed and synthesized. Electrochemical and spectroelectrochemical measurements were performed to investigate absorption, energy levels, electronic ...
Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
(American Institute of Physics Inc., 2021)
Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ...
Numerical study of a swirl gas turbine combustor for turbulent air and oxy-combustion of ammonia/kerosene fuels
(Elsevier, 2021)
Since ammonia has a carbon-free substance and involves hydrogen atoms per volume unit, many scientists think it could be used as an alternative fuel instead of natural gas or kerosene-based fuels in gas turbine combustors. ...
The brominated flame retardants TBECH and DPTE alter prostate growth, histology and gene expression patterns in the mouse
(Elsevier, 2021)
The brominated flame retardants (BFRs), 1,2-dibromo-4-(1,2 dibromoethyl)cyclohexane (TBECH) and 2,3-dibromopropyl-2,4,6-tribromophenyl ether (DPTE) bind to the androgen receptor (AR). in vitro bioassays have shown that ...
Tuning thermoelectric properties of Bi2Ca2Co2Oy through K doping and laser floating zone processing
(Elsevier, 2021)
In the present study, thermoelectric Bi2Ca2-xKxCo2Oy ceramic materials (x = 0.0, 0.05, 0.075, 0.10, and 0.125) in different forms (called bulk, as-grown and annealed fibers) have been manufactured via a classical solid-state ...
Pack-Boriding of Monel 400: Microstructural Characterization and Boriding Kinetics
(Korean Institute of Metals and Materials, 2021)
Monel 400 was pack-borided in the temperature range of 1173-1273 K for exposure times of 2-6 h. The boride layers produced on the surface of the alloy were examined by scanning electron microscopy and phase identification ...
A research on performance appraisal and performance appraisal form development process in hotel enterprises
(Peter Lang AG, 2021)
There is a continued need for overarching and profound approaches to tourism and hospitality. The concept of tourism and hospitality needs to be thoroughly considered so that issues with an ever-increasing complexity and ...
Interval type-2 fuzzy program evaluation and review technique for project management in shipbuilding
(Taylor and Francis Inc., 2021)
Ship production occurs at the end of a complex process and needs effective and efficient Project Management (PM). Uncertainty in project management parameters always exists and is inevitable. The Fuzzy Set Theory is capable ...
A review and research on fuel cell electric vehicles: Topologies, power electronic converters, energy management methods, technical challenges, marketing and future aspects
(Elsevier, 2021)
The implementations of fuel cells (FCs) in the vehicle industry have gained great attention for the last few decades owing to simple utilization, silent operation, high efficiency and modular structure. Technological ...
Age and Growth of Red Sea Goatfish, Parupeneus forsskali from Iskenderun Bay, Northeastern Mediterranean Sea
(Pleiades journals, 2021)
The age composition and growth parameters of Red Sea goatfish, Parupeneus forsskali collected from Iskenderun Bay in the northeastern Mediterranean Sea were investigated. A total of 207 specimens ranging from 113 to 264 ...
