Alginic acid (Alg-H) was applied as a novel aqueous binder for LiNi1/3Co1/3Mn1/3O2 (NMC) positive electrode for lithium-ion batteries (LIBs). We successfully obtained the pH-controlled aqueous slurry without any corrosion of NMC, which can also prevent a corrosion of an aluminum current collector. Using Alg-H can real…
An integrated mathematical model was developed to study the thermo-mechanical behavior of strips and work-rolls during warm rolling process of steels. A two-dimensional finite element analysis was first employed to solve for the thermo-mechanical response of the rolled strip under steady-state conditions. The calculat…
Purpose – Fibrous porous media have a wide variety of applications in insulation, filtration, acoustics, sensing, and actuation. To design such materials, computational modeling methods are needed to engineer the properties systematically. There is a lack of efficient approaches to build and modify those complex struc…
Two effects that have been observed when metals and metal alloys are vibrated during solidification are a decrease in dendritic spacing, which directly affects density, and faster cooling rates and associated solidification times. Because these two effects happen simultaneously during solidification, it is challenging…
Electrodeposition followed by sulfurization could be a favourable process for the fabrication of the CZTS thin film solar cells. Here we attempt to fabricate CZTS thin films from co-electrodeposited precursors of Cu-Zn-Sn with various compositions from Cu-poor, Zn-rich to Cu-rich, Zn-poor. Different characterization m…
Zeolite Beta‐coated stainless steel supports with gradient porosity are employed as filter‐panels for lipase encapsulation. Enzyme encapsulation on the stainless steel porous discs is achieved via vacuum infiltration. Subsequently, two lipase‐encapsulated zeolite Beta‐coated stainless steel discs are attached using an…
Although layered polysilane (LPS) has a graphitelike structure and a higher electric capacity than Si powder, LPS shows poor cycling performance. Therefore, to improve its cyclability, the synthesis of composite materials of LPS and carbon was attempted. Carbon-coated LPS (C-LPS) was prepared by pulsed laser depositio…
Two reaction pathways for synthesis of high molar mass (M w above 50 000 g/mol) aliphatic-aromatic poly(ester-carbonate)s were elaborated. Simple organic carbonates such as dimethyl carbonate or propylene carbonate were used as carbonate linkage sources and dimethyl terephthalate as the precursor of ester linkages. 1,…
As a large group of persistent organic pollutants, polycyclic aromatic hydrocarbons (PAHs) commonly coexist with chlorinated organic compounds in industrial wastewater. Preferential adsorption of PAHs from wastewater and final effluent is essential in pretreatment processes. In this study, a novel nitrogen-doped mesop…
A strong spin-orbit interaction leads to a Rashba-type splitting of the bulk bands of BiTeCl, which results in toroidal Fermi surfaces with distinct spin structures depending on the chemical potential. Here, we present spin- and angle-resolved photoelectron spectroscopy measurements of the three-dimensional spin-orbit…
The properties of the interface between biomaterials and the host tissue play an important role for the process of successful adaptation of implants. Extensive research has focused on shortening the time of osseointegration by modifying the surface in adding a coating such as hydroxyapatite (HAp). We have developed a…
In this study, modification of aluminium silicon eutectic alloy by grain modifier, strontium was investigated on conventional and slope cast A356 alloy. A356 alloy with addition of 0 to 0.97 wt.% Sr was prepared by conventional and slope casting in melting furnace. The molten metal of A356 alloy was casted into steel…
In this study, we report the kinetics of reduction reactions of single and double chain surfactant cobalt(III) complexes of octahedral geometry, cis-[Co(en)2(4AMP)(DA)](ClO4)3 and cis-[Co(dmp)2(C12H25NH2)2](ClO4)3 (en = ethylenediamine, dmp = 1,3-diaminopropane, 4AMP = 4-aminopropane, C12H25NH2 = dodecylamine) by Fe2+…
The major objective of this work was the development of a reliable model to describe the volumetric properties of metals. In this regard, we have applied the Song and Mason equation of state (SM EOS) for alkaline earth metals, aluminium, Germanium, lead, antimony, Bismuth, chromium, manganese, rhodium, palladium, plat…
Anodic oxidation (AO) is a chemical method which used to produce a bioactive layer (oxide) of titanium (Ti). The aim of this study is to evaluate the effect of anodic oxidation upon Ti foil in acetic acid (C2H4O2). The anodic oxidation was performed by varying the applied voltage (10 – 200 V) and concentration of the…
The objectives of this work were to study the ultrasound- and ultraviolet light-induced inactivation kinetics of polyphenol oxidase extracted from different sources in a model system. The polyphenol oxidase crude extract was obtained from bananas, apples, quince, eggplants, plums, dill, and cultured mushrooms, which e…
The development of thin ceramic shell mould in investment casting process is very crucial as this mould inherited brittle property and highly exposed to the cracking mechanism. The slurry composition produces green (unfired) ceramic shell mould which low in strength and easily crack or fail during wax removal or handl…
Rapid prototyping of photovoltaic (PV) cells requires a method for the simultaneous simulation of the optical and electrical characteristics of the device. The development of nanomaterial-enabled PV cells only increases the complexity of such simulations. Here, we use a commercial technology computer aided design (TCA…
Based on the normal-state electronic band structure, the necessary condition for a metal to become a superconductor is the simultaneous occurrence of flat and steep bands at the Fermi level. The sufficient condition at least for conventional superconductors is a strong enough coupling of the flat band states to the la…
Conflict of interest: the authors declare that they have no conflicts of interest. Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) (e.g. Kathon® CG; Dow Chemical Co., Midland, MI, USA) is a mixture of MCI and MI in a ratio of 3 : 1, currently used as a preservative in cosmetic, industrial and domestic produ…
