Characterization of stress softening and self-healing in a double network hydrogel
(Elsevier, 2019)
In this paper, a micro-mechanically based constitutive model is presented to describe stress softening and self-healing in alginate-polyacrylamide (PAAm) double network (DN) hydrogels. The stress softening phenomenon in ...
A straightforward approach for the synthesis of nanostructured Y2O3 particles: synthesis, morphology, microstructure and crystal imperfection
(Elsevier, 2020)
A facile and straightforward approach has been implemented for the synthesis of nanostructured Y2O3 particles via sol-gel method from yttrium nitrate solution. The individual effects of calcination temperature, ...
The effect of preceramic soldering on fracture resistance of 4-unit zirconia fixed dental prostheses
(Wiley, 2022)
Purpose Preceramic soldering of zirconia may deliver better fitting restorations. However, there is not sufficient evidence regarding the influence of preceramic soldering of zirconia restorations on mechanical strength. ...
Rapid heating and cooling chamber for a photonics junction measurement system
(IEEE Computer Society, 2020)
Since many industrial applications require heat treatment processes or validation tests under certain ambient temperatures, thermal design is a key issue to be considered in order to ensure fast heating and cooling ...
Wetting behavior of superhydrophobic poly(methyl methacrylate)
(Elsevier, 2018)
Superhydrophobic PMMA surfaces were prepared by spin-coating and doctor blade coating of PMAA/hydrophobic silica (1/10 by weight) dispersions in toluene onto glass substrates. Influence of the number of coating layers ...
Design of fault-tolerant cascaded H-Bridge multilevel inverter with output-side transformers using bidirectional switches
(Institute of Electrical and Electronics Engineers Inc., 2015)
Globally increasing energy demand, running short of fossil fuels and researches for finding environment friendly choices strengthen a solution of local electricity production, especially from renewable energy sources. In ...
Optimal dimensioning of retaining walls using explainable ensemble learning algorithms
(MDPI-Multidisciplinary Digital Publishing Institute, 2022)
This paper develops predictive models for optimal dimensions that minimize the construction cost associated with reinforced concrete retaining walls. Random Forest, Extreme Gradient Boosting (XGBoost), Categorical Gradient ...
LGM Glaciations in the Northeastern Anatolian Mountains: new insights
(MDPI-Multidisciplinary Digital Publishing Institute, 2022)
Barhal Valley belongs to the Coruh Valley System in the Kackar Mountains of northeastern Anatolia. This 13 km long valley is located to the south of the main weather divide and to the east of Mt. Kackar, with the highest ...
An improvement on selective separation by applying ultrasound to rougher and re-cleaner stages of copper flotation
(Mdpi, 2020)
It has been known that the power ultrasound is used as a pretreatment and rarely applied as a simultaneous method to improve grade and recovery during froth flotation processes. This work aimed at investigating the impact ...
Generalized code index modulation and spatial modulation for high rate and energy-efficient MIMO systems on rayleigh block-fading channel
(IEEE, 2021)
In this article, a high data rate and energy-efficient multiple-input multiple-output transmission scheme is considered by combining two popular and rational modulation techniques: spatial modulation (SM) and code index ...
