Ammonia is a critical pollutant in biological wastewater and not easily separated mechanically due to similar physical properties (e.g., molecular weight, polarity, etc.) water. Currently, an agent for ammonia removal from using zeolites must be mined, which environmental-friendly. The development of sustainable absorbent ammonia-containing therefore desirable. Since microalgae can grow rapidly by feeding on waste nutrients up-taking carbon dioxide flue gas, it high interest used as...
CdS nanoparticles were successfully synthesized using cadmium acetate and sodium sulfide as Cd S precursors, respectively. The effect of thiosulfate an additional sulfur precursor was also investigated (combined milling). samples characterized by XRD, Raman spectroscopy, XPS, UV-Vis PL DLS, TEM. Photocatalytic activities both compared. photocatalytic activity CdS, which is produced combined milling, superior to that obtained route in the degradation Orange II under visible light irradiation....
Twelve Cu-based ternary (Cu–Me1–S, Me1 = Fe, Sn, or Sb) and quaternary (Cu–Me2–Sn–S, Me2 Zn, V) nanocrystalline sulfides are shown as perspective antibacterial materials here. They were prepared from elemental precursors by a one-step solvent-free mechanochemical synthesis in 100 g batch using scalable eccentric vibratory ball milling. Most of the products have strong activity against Escherichia coli Staphylococcus aureus bacteria. For instance, stannite Cu2FeSnS4 mohite Cu2SnS3 most active...
This work explores ceramic additive manufacturing in combination with liquid metal infiltration for the production of degradable interpenetrating phase magnesium/hydroxyapatite (Mg/HA) composites. Material extrusion was used to produce stoichiometric, and calcium deficient HA preforms a well-controlled open pore network, allowing customization topological relationship composite. Pure Mg two different alloys were infiltrate by means an advanced method inspired spark plasma sintering, using...
This study reports the production of a Mg/15%β-tricalcium phosphate Ca3(PO4)2 composite by combining direct ink writing for β-TCP preform and liquid infiltration technique to obtain continuous metal matrix composite. The influence volume fraction in situ reaction between ceramic on microstructure mechanical properties were investigated detail. was uniformly distributed matrix, forming three-dimensional (3D) network. obtained characterized means relative density (He pycnometry), X-ray...
Abstract Cu 2 SnS 3 (CTS) is a simple and promising material for solar cells. Various physical chemical techniques have been employed synthesis of CTS nanocrystals among which mechanochemical great alternative due to its simplicity, solvent‐free character, reproducibility. We present the analysis vibration properties mechanochemically synthesized nanocrystals. The milling time influence on from elemental precursors Cu, Sn, S was observed. scanning electron microscopy (SEM), X‐ray diffraction...
Tricalcium phosphate (Ca3(PO4)2, TCP) is a ceramic widely used as bone filler material due to its good osteoconductivity. Nevertheless, poor mechanical properties do not allow use for load-bearing applications. Therefore, the option of improving strength and toughness by adding biocompatible metallic component promising alternative overcome this drawback, leading fabrication improved implants. The present work focused on defining thermal stability alpha-TCP (α-TCP) when it sintered together...
In this study, the structure, morphology and composition of synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, its adsorption performance with respect to As(V) Cr(VI) studied. Magnetite (MG) modified 3D printed was obtained by two step procedure: modification 3D_W 3-aminoproylsilane (APTES) followed controlled magnetite deposition obtain 3D_W/M adsorbent. The structure/properties confirmed applying FTIR, XRD, TGD/DTA, SEM analysis. properties hybrid...
The usage of iron alloys for bone fractures treatment has been limited due to its high density and elastic modulus, as compared bone. In contrast, the use tricalcium phosphate (TCP), a ceramic that promotes healing, is mostly by brittle nature. present work fracture mechanism novel iron-TCP interpenetrated composite fabricated spark plasma sintering was studied. Specimens were subjected diametral tensile-strength-test. determined indirect tensile loading conditions using strength test....
The fabrication of a composite material based on magnesium (Mg) and tricalcium phosphate is reported in this work. Rods β-tricalcium (β-TCP) were processed consolidated together with pure Mg powder through spark plasma sintering (SPS). microstructure at the interface, chemical composition transformation components microhardness analysed. shows two zones well-defined continuous interface between them: ceramic zone composed by β-TCP filled metallic constituted rich eutectic.

Abstract The presented study proposes an efficient utilization of a common Thymus serpyllum L. (wild thyme) plant as highly potent biosorbent Cu(II) and Pb(II) ions the interaction copper-laden with two opportunistic bacteria. Apart from biochars that are commonly used for adsorption, here we report direct use native plant, which is potentially interesting also soil remediation. highest adsorption capacity ( q e = 12.66 53.13 mg g −1 , respectively) was achieved after 10 30 min respectively....
