A series of poly (amino acid) with zwitterionic character was prepared for surface coating to avoid protein adsorption, by modifying the poly (aspartic acid) side chain with tertiary amine groups. An interesting and facile procedure is described with starts with polysuccinic acid which is followed by ring-opening with…
Abstract The fracture behavior of medium density polyethylene/calcium carbonate (MDPE/CaCO3) nanocomposites was evaluated using the essential work of fracture (EWF) test. Fracture surfaces and the deformation zone in front of the precrack were studied using different microscopy techniques. Microscopic observations pro…
Custom electrochemical cells are necessary for fundamental in situ characterization experiments and applied transport studies of next-generation batteries. Limited data on the chemical compatibility of nonaqueous battery electrolytes and engineering materials frustrate experimental progress across laboratories. In thi…
Composite materials obtained with natural and sustainable fibers can be used successfully in many areas on their own. In recent years, high-strength fibers such as hemp, sisal, linen, jute, wood sawdust and bamboo are more preferred in composite materials. In this study, the effect of the hornbeam sawdust size on the…
The low-cycle fatigue behavior and damage progression of a SiC fiber reinforced Ti–6Al–2Sn–4Zr–2Mo-0.1Si matrix composite was investigated systematically. The fatigue life increased from 4 to 52388 cycles when the maximum stress decreased from 1500 MPa to 1100 MPa. The modulus calculated from the stress-strain respons…
This work focuses on the development of biodegradable active films packaging using natural compounds by reducing the plastic waste to environment but also as a potential substitute of synthetic preservative in food. Active film packaging was formulated using semi-refined carrageenan (SRC) biopolymer plasticized with g…
Due to its low bandgap and high optical efficiency, tellurium is considered an important material candidate for mid-infrared applications. Taking advantage of its structural anisotropy, we fabricated tellurium nanowire devices and investigated the radiative interaction of charge carriers by the polarization-resolved p…
The effect of Ti substitution on the microwave and magnetostatic properties of nanostructured hexagonal BaFe12−xTixO19 ferrite composites is studied. The microwave permeability is measured in the frequency range of 0.1–22 GHz by a coaxial technique. An analysis of the magnetostatic data is made by the law of approach…
Adding chromium to an iron alloy enables shape recovery over a wide temperature range
Green composites are a special class of composites in which at least one of the components is obtained from natural resources. They are an alternative to traditional composites because of their useful properties such as biodegradability, low cost, easy processability, sound insulation and recycling. Green composites,…
The effective exploitation of the intriguing theranostic features of noble metal nanoparticles for therapeutic applications is far from being a routine practice due to the persistence issue. In this regard, passion fruit-like nano-architectures (NAs), biodegradable and excretable all-in-one, nature-inspired platforms…
Revalorizing organic biowaste is critical to achieve a full circular economy, where waste is transformed into resources. One of the main strategies is to produce activated carbons and use them as functional materials for electrochemical energy storage. In this study, winemaking wastes, bagasse (BAG), and cluster stalk…
Silicon nanoporous membranes provide the fundamental underlying technology for the development of an implantable bio-artificial kidney. These membranes, which are comprised of micromachined slit-pores that are nominally 10 nm wide, allow for high-efficiency blood filtration as well as immunoprotection for encapsulated…
Abstract Introducing fluorocarbon vapor in the air above an aqueous dispersion of clusters of nanodiamonds induces their disaggregation, a prerequisite for most of their biomedical uses. Furthermore, the fluorocarbon gas promotes the adsorption of nanodiamonds at the gas/water interface. As an example of the benefits…
High Resolution Image Download MS PowerPoint Slide To understand the thermal characteristics, nonisothermal kinetic models, and volatile constituents during the energy conversion of bituminous materials at the fraction level, differential scanning calorimetry–mass spectrometry tests were performed on bituminous four f…
Tunable optical phased arrays and metasurfaces play an important role in a diverse range of applications from imaging and remote sensing to communications and displays. However, as the number of tunable elements grows, the required control architecture becomes insurmountably complex. Here, we discuss the concept of pe…
Herein, we investigated the effect of electrospun polycaprolactone fumarate (PCLF) nanofibers on neural stem cell (NSC) behavior in the in vitro setting. Murine NSCs were isolated from adult mice subventricular zone and immunophenotyped by flow cytometry assay and immunofluorescence staining. Cells were cultured on th…
Although smart windows have received wide attention as energy-saving devices, conventional metal-to-insulator materials such as VO 2 hinder their commercial usage because of their high transition temperature and low solar energy modulation. Further development can be achieved by finding a new material system that can…
For many years, chemical pesticides have been performed to control different pests and diseases and this may be due to their broad spectrum of action, easy of application and the relatively low cost. But these chemicals have environmental risks, thus alternative control agents are needed. Chitosan is one of the novel…
The ability to track interfacial dynamics of a single nanoparticle at the solution-solid interface is crucial for understanding physical, chemical, and biological processes, but it remains a challenge. Here, we demonstrated a plasmonic imaging technique that can track unlabeled nanoparticles at the solution-solid inte…
