The WS(2)dependence on the elasticity and optical band gap energies of swollen PAAm composites
(Sage Publications Ltd, 2021)
New generation nano-filler polymer composites have many applications including biomedical, electronic and maritime related applications because of their mechanical, electronic and optical properties. The properties of ...
Elastic Properties of a Swollen PAAm-NIPA Copolymer with Various NIPA Contents
(Taylor & Francis Inc, 2014)
Copolymer based on cross-linked polyacrylamide (PAAm) having N-isopropylacrylamide (NIPA) was prepared and their elastic properties were studied as a function of NIPA contents. NIPA content dependency of the shear modulus, ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific Publ Co Pte Ltd, 2014)
Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N, N'-methylene bis (acrylamide) ...
Antimicrobial cerium ion-chitosan crosslinked alginate biopolymer films: A novel and potential wound dressing
(Elsevier Science Bv, 2017)
Wound dressings require good antiseptic properties, mechanical strength and, more trustably, natural material ingredients. Antimicrobial properties of cerium ions and chitosan are known and alginate based wound dressings ...
Evaluation of the fractal dimension of polyacrylamide during gelation and swelling
(Elsevier, 2021)
The photon scattering method was performed to monitor the free radical crosslinking copolymerization (FCC) of acrylamide (AAm) applied with N,N'-methylenebis (acrylamide) (Bis) in time. FCC experiments were conducted using ...
An improved hybrid feature reduction for increased breast cancer diagnostic performance
(Springer Verlag, 2014)
Methods: A hybrid method is proposed using the independent component analysis (ICA) and the discrete wavelet transform (DWT) to reduce feature vectors of Wisconsin diagnostic breast cancer (WDBC) data set. Two independent ...
Fractal dimension and phase transition of graphene oxide (GO) doped polyacrylamide
(Elsevier Sci Ltd, 2020)
Graphene Oxide (GO)- Polyacrylamide composites prepared between 5 and 50 mu l GO were performed by Fluorescence Spectroscopy. The phase transition performed on the composites was measured by calculating the critical ...
Cohomological dimension and top local cohomology modules
(Rocky Mountain Mathematics Consortium, 2019)
Let R be a Noetherian ring, I an ideal of R and M an R-module. In this paper, we first determine a condition under which a given integer t is a lower bound for the cohomological dimension cd(I,M), and use this to conclude ...
Electrical, optical and mechanical properties of chitosan biocomposites
(Sage Publications Ltd, 2020)
In this work, chitosan/graphene nanoplatelets (CS/GNP) and chitosan/multi-walled carbon nanotube (CS/MWCNT) biocomposite films were prepared using a simple, eco-friendly and low-cost method. The electrical, optical and ...
ECG feature extraction based on the bandwidth properties of variational mode decomposition
(Iop Publishing Ltd, 2016)
It is a difficult process to detect abnormal heart beats, known as arrhythmia, in long-term ECG recording. Thus, computer-aided diagnosis systems have become a supportive tool for helping physicians improve the diagnostic ...
