The work carried out over the course of a three year period in three different areas is summarized. Experimental techniques for determining the impact mechanical properties of fiber reinforced epoxy laminates are studied. The experimental results obtained from the tensile, compressive and interlaminar shear properties…
This paper presents an electromagnetic inversion algorithm for the design of cascaded metasurfaces that enables the design process to begin from more practical output field specifications such as a desired power pattern or far-field performance criteria. Thus, this method combines the greater field transformation supp…
Metalenses offer the ground-breaking opportunity to realize highly performing low-weight, flat and ultrathin, optical elements which substantially reduce size and complexity of imaging systems. Today, a major challenge in metalenses design is still the realization of achromatic optical elements ideally focussing a bro…
Conducting efficient performance estimations of neural architectures is a major challenge in neural architecture search (NAS). To reduce the architecture training costs in NAS, one-shot estimators (OSEs) amortize the architecture training costs by sharing the parameters of one "supernet" between all architectures. Rec…
Organic reactions are usually assigned to classes grouping reactions with similar reagents and mechanisms. Reaction classes facilitate communication of complex concepts and efficient navigation through chemical reaction space. However, the classification process is a tedious task, requiring the identification of the c…
The swelling behavior of 18Cr10NiTi austenitic stainless steel and its strengthened by Y2O3-ZrO2 nanooxides version irradiated with 1.4 MeV Ar-ions up to dose 30 displacements per atom (dpa) with simultaneously implanted argon to the levels 200 appm at temperatures of 550…650 ºC was investigated. Transmission electron…
The hydrolysis of hydrophobic and unstructured proteins is difficult due to their poor solubility in aqueous solutions. This study demonstrates the ability of ZrIV-substituted Keggin polyoxometalate (Et2NH2)10[Zr(α-PW11O39)2] to promote selective hydrolysis of β-casein, an intrinsically unstructured protein consisting…
Titanate nanotubes (TNTs) fabricated through microwave-assisted synthesis were examined for their ability to catalyze hydrogen production from a 20% v/v methanol solution under UV and visible light irradiation. Herein, TiO2 was used not only as the raw material for TNT synthesis but also as a reference support to comp…
In this study, we offer a numerical platform to detect the locations of high-stress zones in the prosthetic heart valve, in the mitral position, during the closing phase due to existing wrinkles. The intended prosthetic valves in this study have the same shape as the native mitral valve but made of synthetic biomateri…
A series of poly(ethylene oxide)-LiOTf electrolyte films were prepared using a variety of hydrocarbon templates as nanofillers, resulting in observable nanophase separation in the polymer electrolyte. Upon partial extraction of the nanofiller template, an enhanced conductivity over 2 orders of magnitude was measured u…
Abstract Metasurfaces with high-quality (HQ) resonances are always desired for their potential applications in biomedicine and photonic devices. However, the realization of HQ near-infrared metasurfaces with polarization insensitivity has faced problems with metallic loss, large feature size and limited configurations…
A tremendous increase in the entry of drug delivery systems (DDSs) based on nanotechnology has been observed as a result of the ability of pharmaceutical nanotechnology to overcome the various drawbacks related to the first generation DDS. The patent period of these proprietary branded drugs gives its manufacturers so…
A new spider species, Cybaeus daimonji, from Kyoto, western-central Honshu, Japan is described based on both sexes. The shape of epigyne indicates that this new species is close to C. communis Yaginuma, 1972, C. kirigaminensis Komatsu, 1963, C. maculosus Yaginuma, 1972 and C. shinkaii (Komatsu, 1970), which are distri…
Nanomedycyna jest obecnie jedną z najszybciej rozwijających się dziedzin nanotechnologii, znajdującą coraz więcej zastosowań w walce z chorobami nowotworowymi. Nanocząstki złota, ze względu na swoje unikalne właściwości optyczne i chemiczne, cieszą się rosnącym zainteresowaniem naukowców. Do zalet nanocząstek złota na…
We describe a method for measuring the shape of a toroidal magnetic field (such as in a stellarator) to demonstrate the existence and nature of magnetic surfaces. We detect the successive circuits of a pulse of low energy, phase stabilized electrons injected parallel to the field and stored for many thousands of circu…
Abstract Spin ice is an exotic type of magnetism displayed by bulk rare‐earth pyrochlore oxides. We discovered a spin ice‐like magnetic relaxation of [{Mn(saltmen)}4{Mn(CN)6}](ClO4)⋅13 H2O (saltmen2−=N,N′‐(1,1,2,2‐tetramethylethylene)bis(salicylideneiminate)). This magnetic system can be considered as a two‐dimensiona…
The regularities of structural formation of the weld metal and HAZ during multilayer welding, made by the transverse humping method, with short sections of defects on cast steel 15Kh1M1FL with perlite electrodes without heating and heat treatment are considered. It has been established that the structure of all the st…
Due to unsatisfactory results and reported drawbacks of anterior cruciate ligament (ACL) reconstruction new regenerative approaches based on tissue-engineering strategies are currently under invest...
Abstract The main purpose of the present study is to verify the possibility of decarbonizing the surface of heat-resistant ductile iron GJS-XSiMo5-1 to provide a significant difference in carbon content between this material and gray cast iron ENGJL-250. In the future, this will allow to increase the diffusion of elem…
In this research, the solubility, permeability and diffusivity of gas mixtures through glassy polymers were comprehensively studied. The diffusivity of the components in the mixture was assumed to be a function of the concentration of all components in the mixture. Then, the permeability of pure species was expanded t…
