The structural, magnetic, electrical, and dilatation properties of the rare-earth NdCoO3 and SmCoO3 cobaltites were investigated. Their comparative analysis was carried out and the effect of multiplicity fluctuations on physical properties of the studied cobaltites was considered. Correlations between the spin state c…
Polyesteramide (PEA) based hot melt adhesive (HMA) was successfully designed containing a high content of renewable mass. The PEA HMA was synthesized based on dimer acid (DA), catechol, ethylenediamine (EDA), ricinoleic acid amide (RA amide) which was synthesized by using ricinoleic acid and diethanolamine. RA amide w…
Molecular lanthanoid complexes are highly valuable building blocks for a number of important technological applications, e.g. as contrast agents in magnetic resonance imaging (MRI) or as luminescent probes for bioassays. For the next generation of advanced applications based on molecular species, heterooligonuclear la…
Abstract The production of low dielectric materials that can be used in high temperature environments is the primary aim of this work. A cross‐linked structure is introduced into fluorinated poly(aryl ether) (named as FPAE) with high molecular weight (Mw, 140 000 g mol−1) and linear molecular structure using nucleophi…
This chapter summarizes the progress in the development of hyaluronic acid (HA)-functionalized inorganic nanohybrids as nanocarriers for drug delivery and discusses the promising results of these nanohybrids for cancer therapy. In particular, extensive research has been conducted to develop hyaluronan or HA-functional…
Corrosion performance of graphene oxide (GO) coatings from different sheets sizes in 3.5 wt% NaCl solution was investigated. The GO dispersion was subjected to 5 and 10 hours of ultrasonication before electrophoretically deposited (EPD) onto the copper substrate. It was found that the EPD-GO coating from smaller sheet…
Nanoparticles are an increasingly important tool in chemistry research, but currently there are few opportunities for chemistry students to work with nanoparticles in undergraduate analytical courses. In this exercise, designed for an analytical or instrumental analysis lab course, students have the opportunity to wor…
Cellulose as a renewable material has received enormous interest in recent time with an effort to minimize the environmental load from mining earthborn functional materials as well as reducing carbon footprint. This work demonstrates that high quality cellulose could be produced from empty fruit bunch of oil palm plan…
Abstract Anti‐encrustation additives were mainly investigated in nitric acid solution with zirconium (Zr), molybdenum (Mo), and tellurium (Te) to prevent the encrustation of zirconium molybdate hydrate (ZMH). The ZMH generated by reaction crystallization of Mo and Zr as main fission products has a high adhesion proper…
Abstract In field-effect transistors (FETs), when the thickness of the semiconducting transition metal dichalcogenides (TMDs) channel exceeds the maximum depletion depth, the entire region cannot be completely controlled by a single-gate electric field. The layer-to-layer carrier transitions between the van der Waals…
Fluidized beds have been utilized for various chemical and physical applications including heat transfer such as the gas–solid heat exchanger. It is advantageous to use carbon nanotubes (CNTs) with high thermal conductivity as bed materials for heat transfer enhancement in a direct gas–solid contacting heat exchanger.…
Enhancement of heating of a droplet on a hydrophobic surface is investigated. A vertical metal (column) pin is introduced in the droplet and the fluid heating, due to the column pin, is examined. The droplet heating is initiated at the hydrophobic surface and the column pin located in the droplet. The effect of the fl…
Abstract A series of first-principles calculations using Kohn–Sham density functional theory have been used to study MnPSe 3 /WS 2 heterostructures. The Heyd–Scuseria–Ernzerhof (HSE06) hybrid functional has been chosen as the exchange–correlation potential because it gives energy gaps accurately. Five possible atomic…
Previously, we have described the preparation of a novel fibroin methacrylamide (FbMA), a polymer network with improved functionality, capable of photocrosslinking into Fb hydrogels with elevated stiffness. However, it was unclear how this new functionality affects the structure of the material and its beta-sheet-asso…
The influence of the condition of through-holes on the corrosion of galvanic test assemblies was studied. Holes in coated aluminium alloy 7075-T6 were tested as received, in a worst-case bare condition and with extra protection. Regions away from fastener holes were also tested. Corrosion performance was assessed by e…
The investigations on wear resistance, mechanical properties, and microstructure of three steels with different additions of chromium (Cr) and nickel (Ni) are conducted. Continuous cooling treatment is conducted to obtain martensitic/bainitic dual‐phase microstructure, and wear behavior is analyzed. The results indica…
Abstract Presented here is a novel system that uses an aluminum-based fuel to continuously produce electrical power at the kilowatt scale via a hydrogen fuel cell. This fuel has an energy density of 23.3 kW h/L and can be produced from abundant scrap aluminum via a minimal surface treatment of gallium and indium. Thes…
As a trial to realize kink band strengthening in titanium alloys, slight cold rolling followed by aging heat treatment were applied on Ti–12 mass% Mo alloys for obtaining mille-feuille-like layered hcp (α)/bcc (β) two phase structure. After slight cold rolling at rolling reduction of 5% and subsequent aging heat treat…
Abstract Designing high efficiency microwave absorbers with frequencies in 1 GHz is still a huge challenge in practical applications. We design and present a novel microwave metamaterials absorber at six frequency points of 160, 442, 530, 723, 765 and 965 MHz with absorptances up to 90%, which is insensitive to polari…
Heusler-type magnetic shape memory alloys (MSMAs) exhibit a martensitic transformation (MT) accompanied by a complex magnetic reordering, strongly affected by an intricate martensitic microstructure. The hierarchic twin structure of martensite, formed as a result of minimization of elastic energy down to atomic scale,…
