In polymer matrix composites, the interface between reinforcing phase and bulk is paramount to overall performance of composite as a structural material. This now thought be distinct, three-dimensional surrounding called interphase. The developments atomic force microscope nanoindentation devices have facilitated investigation Previously, modulation microscopy (AFM) were primary methods used determine size interphase its stiffness relative phase. present utilized imaging AFM examine in glass...
Parkinson’s disease (PD) is a neurological disorder affecting the nerve cells. PD gives rise to various conditions, including gradual reduction in movement speed, tremors, limb stiffness, and alterations walking patterns. Identifying its initial phases crucial preserving well-being of those afflicted. However, accurately identifying early intricate due aging population. Therefore, this paper, we harnessed machine learning-based ensemble methodologies focused on premotor stage create precise...
Abstract Nanoindentation was performed on Ti-B-Si-C and SiCN films deposited Si substrates at varying loads depths of penetrations. The intensity chipping got enhanced with an increasing load which represented geometrically. pop-in pop-out events occurring in the unloading were explained as cracking high-pressure phase transformation. interfacial fracture stability adhesion film-substrate system, crucial for N/MEMS devices analyzed respect to frictional coefficient help Finite Element...
Abstract Nanoindentations were performed in the near fiber region of matrix a polymer composite to attempt determine nanomechanical properties interphase. A possible bias effect was observed and this confirmed by performing nanoindentations both presence absence fiber. Changes experimentation using lower loads (40 μN 80 μN) reduced effect. Cutting samples at an angle axis try further reduce The experimental variations considerably Specifically, combination angled cutting use eliminated...
Nanoindentation load-depth (P-h) plots is the basis for determination of mechanical properties samples and especially vital thin coatings deposited on substrates various makeup from amorphous-brittle (borosilicate glass) to Silicon (having different crystallographic texture) ductile like stainless steel as well other aspects indenter tip shape. The elastic-plastic response by simulated P-h per modified empirical relations have been presented. outcomes this computational studies enlighten...
Cu thin films were deposited on Si(111), glass, and quartz substrates by magnetron sputtering. X‐ray diffraction, SEM, photoemission electron microscope studies carried out to characterize the films. An influence of nature substrate 2 O CuO phases formed was observed. Copper silicide formation in case silicon aided rather than unlike glass substrates. Formation nanocrystallites observed SEM diffraction. Copyright © 2016 John Wiley & Sons, Ltd.
Crop stage-specific information on the impacts of projected climate change crop and irrigation water requirements are essential for improving productivity. This study investigated possible implications phenology, effective rainfall (Peff), (CWR) (IWR) maize in eight locations India. CWR, Peff IWR were estimated seven stages viz., emergence, 5th leaf stage, tasseling, silking, milking, dough maturity during baseline (1980–2009) near-century (2022–39) using data derived from a subset 29...
The effect of substrate was studied using nanoindentation on thin films. Soft films hard showed more pile up than usual which attributed to the dislocation at film interface. tip blunting load depth and hardness plots shown. experimental date variation Vickers with thickness loads were fitted new parameters analyzed. delaminated area analyzed geometrical shapes optical view failure region along displacement Indentation fracture Nanoindentation Berkovich indenter has been studied. toughness...
High resolution x-ray diffraction study of the substrate temperature and thickness dependent microstructure reactively sputtered
Nanoindentation is an effective way of finding mechanical properties at nanoscale. They are especially useful for thin films where elimination the substrate effect required. The mechanism based upon depth sensing indentation on Oliver and Pharr modeling. load-depth curves as well time sample were analyzed. Indentation impulse was found to have significant contribution in nature failure zone during indentation. Fracture toughness also related sample.
During the winter season in India, AQI experiences a decrease due to limited dispersion of APs caused by MFs. Therefore, we developed sophisticated green predictive model GAP, which utilizes our designed technique and customized big dataset. This dataset is derived from weather research tailored forecast future levels Indian subcontinent during winter. has been meticulously curated amalgamating samples MFs concentrations, further adjusted reflect yearly activity data across various states....
Copper (Cupric) oxide is a readily synthesized, non-toxic metal with wide range of uses, including the treatment water, manufacture electronic devices, solar cells, cathodes for lithium-ion primary batteries, gas sensors, electrochromic supercapacitors, and field effect transistors. The effects Zn doping in CuO three different concentrations (weights %) were investigated. band gap carrier concentration altered due to formation defect energy states, lattice stresses, ZnO, Cu2O addition CuO....
Stannic oxide (SnO2) synthesized by the sol-gel method showed efficient optoelectronic mobility due to high crystallinity and coagulation involved in morphology.
