Aluminum (Al) alloys are used widely in the automotive and aerospace industries, but their corrosion resistance is insufficient in long-term service, particularly in a high-salinity environment. The incorporation of molybdenum disulfide (MoS2) particles into plasma electrolytic oxidation (PEO) coatings formed on an aluminum alloy was investigated in this work. After oxidation, the coatings were investigated

As one common industrial waste liquid, waste copper (Cu) etchant can seriously pollute the environment if it is unreasonably managed. Herein, tetrahedron-like copper (I) chloride (CuCl) crystals were extracted from waste copper etchant by way of facile electrodeposition, and the effect of the electrodeposition time on the lithium (Li)-storage capacity of the copper (I) chloride crystal was further

Bismuth (III) (Bi3+) and chloride (Cl−) ion co-doped Li3V1·97Bi0·03(PO4)3−x Cl x /carbon (C) compounds (x = 0·03, 0·05, 0·07, 0·09) were prepared by way of a simple sol–gel method. The X-ray diffraction patterns proved that a small amount of bismuth (III) and chloride ion doping does not change the crystal structure of lithium vanadium phosphate (Li3V2(PO4)3). Charge/discharge results showed that bismuth

A tungsten (W)-doped microarc oxidation (MAO) coating on a TC4 titanium (Ti) alloy drill pipe was prepared by adding sodium tungstate (Na2WO4) into electrolytes. The effects of adding different concentrations on the electrical conductivity of the electrolyte and the performance and structure of MAO coatings on the titanium alloy drill pipe were studied. The electrical conductivity of the solution was

In this study, atmospheric plasma spraying was used for the preparation of a CoNiCrAlY bonding layer on a nickel (Ni)-based superalloy with different laser shock times designed for surface modification. In addition, electron-beam physical vapor deposition was used to deposit a ceramic layer to form a new modified coating. When comparing high-temperature oxidation resistance with mechanical properties

In the present work, α-bismuth (III) oxide (α-Bi2O3) photocatalysts with a porous and nanosheet structure were prepared by using the biomimetic-synthesis-assisted hydrothermal method. l-Arginine (C6H14N4O2) was used as the biomimetic template, and the pH value range of the precursor solution was 3–12. The as-obtained samples were characterized by X-ray diffraction, field-emission scanning electron

The aim of this work was to achieve improved dispersibility of hydrophobic dry lubricants in aqueous media through plasma activation. As a result, the use of wet-chemical environmentally questionable substances – for example, certain surfactants – to ensure the dispersibility of such particles can be avoided. These plasma-activated particles can be further embedded in electroless nickel (Ni) coatings

In the present study, phytic acid was used as an environmentally sustainable phosphorus-containing flame retardant (FR) to improve the flammability of cotton fabrics. The facile preparation approach is adequate for offering an intumescent FR system for cotton, as phytic acid and triethanolamine could serve as the acid source and blowing agent, respectively, and a cellulose substrate may function as

A variety of bioinorganic ions have been reported to alter different cellular functions, including the transport of potassium (K+) and calcium (Ca2+) ions, while also modulating signal transduction, energy metabolism and cell proliferation due to the electro-potential change of the cell membrane. It was recently reported that the presence of such bivalent cations in the bone system is beneficial to

Understanding the surface interactions and reactivity of zinc (Zn)-based biomaterials with constituents of physiological fluids such as proteins and ions is essential for an accurate evaluation of biomaterial corrosion initiation and progression. In this paper, the effect of the albumin addition on the corrosion behavior of pure Zn and Zn–4Ag alloy is discussed. The corrosion behavior of Zn-based materials

Ideal hydrogels for tissue engineering applications should mimic the properties of native extracellular matrices and optimize the cell behavior. Silk fibroin (SF) that possesses tunable mechanical strength and low cytotoxicity and elastin protein that stimulates cell viability are complementary for hybrid hydrogels. Here, hydrolyzed elastin peptide (HEP) and reconstituted SF (RSF) are combined to generate

To understand the magnesium (Mg) degradation mechanism in vivo, a variety of in vitro investigations have been conducted. However, there is still a gap between in vitro results and in vivo observations. Herein, the combined effect of proteins and medium-flow conditions on magnesium degradation was studied. Bovine serum albumin (BSA) and fetal bovine serum (FBS) were employed as the commonly used protein

Silver nanoparticles (AgNP) are promising candidates for fighting drug-resistant infections because of their intrinsic antimicrobial effect. The design of high-yield antimicrobial molecules may inadvertently cause variation in host cells' biological responses. While many factors affect AgNPs' efficacy, their surface is exposed to the biological environment and thus plays a critical role in both the

Polyethylene glycol (PEG) coatings have been commonly used in reducing protein adsorption with the intent of improving a biomaterial's biocompatibility. To elucidate the role of PEG surface density in reducing protein adsorption, two types of grafted PEG surface density gradients were evaluated for the adsorption and desorption of albumin and fibrinogen, two blood proteins. PEG density gradients were
