Carbon nanoparticles are a class of materials with extraordinary properties. In the past three decades, four major types of carbon nanoparticles were synthesized and investigated: fullerenes, carbon nanotubes, graphene and carbon quantum dots. One of the main properties of such materials is their hydrophobic nature. A…
It remains challenging to develop new materials exhibiting enzyme-like activities and understand the structure-property correlations and catalytic mechanisms. In this study, the characteristics, mechanisms, and applications of a light-activated mimic oxidase based on semiconducting polymer dots (Pdots) prepared from a…
A novel chiral Ag <sub>18</sub> (μ <sub>8</sub> -S)( <italic>p</italic> -TBBT) <sub>16</sub> (PPh <sub>3</sub> ) <sub>8</sub> nanocluster with a meso-shell (Ag <sub>10</sub> S <sub>16</sub> P <sub>8</sub> motif) and a crown-like core (SAg <sub>8</sub> motif) is reported.
The molecular dynamics of the triphenylene-based discotic liquid crystal HAT6 is investigated by broadband dielectric spectroscopy, advanced dynamical calorimetry and neutron scattering. Differential scanning calorimetry in combination with X-ray scattering reveals that HAT6 has a plastic crystalline phase at low temp…
Phase-pure orthorhombic compositions at a Ln/Mo ratio ∼ 5.2-5.7 (Ln = Gd, Dy, Ho) have been obtained for the first time by prolonged (40-160 h) heat treatment of mechanically activated 5Ln2O3 + 2MoO3 (Ln = Gd, Dy, Ho) oxide mixtures at 1200 °C. Although the starting Ln : Mo ratio was 5 : 1 (Ln10Mo2O21 (Ln = Dy, Ho)),…
Alginate microspheres containing layered double hydroxides intercalated with borate: reduction on boron leaching and increasing boron uptake by plants.
In this paper, a new aging platform combined the high voltage electric field and the hydrothermal environment was built.
We report high-resolution scanning tunneling microscopy (STM) study of nano-sized Pb islands grown on SrTiO 3 , where three distinct types of gaps with different energy scales are revealed. At low temperature, we find that the superconducting gap ( Δ s ) in nano-sized Pb islands is significantly enhanced from the one…
-QD) with good magnetic properties and high fluorescence retention was successfully fabricated from linked magnetic nanoparticles and quantum dots. The resulting material can qualitatively and quantitatively detect four kinds of antibiotics and maintain high recovery rates.
A semiorganic crystal of Boricacid potassium acetate has been grown by low temperature solution growth technique at room temperature using deionized water as a solvent. The crystalline nature of the compound was confirmed by the sharp and well defined peaks observed from the powder X-ray diffraction pattern. By single…
The recycling of polyethylene terephthalate (PET) is the most attractive method for PET waste management because it not only decreases the load on landfill space, but also provides opportunities for reducing the use of raw petrochemical products. Therefore, in this investigation, neopentyl glycol is used for alcoholys…
A novel method is proposed to fabricate polyoxometalate-based metal-organic frameworks (POM@MOFs) by using the ability of POMs to oxidize metals to cations. The morphology-controlled growth of POM@MOFs (NENU-n) is achieved in the absence of any modulators and an effect of polyoxoanion charge number on morphology is ob…
The main purpose of this research is to optimize the process to change useless fish scales to be a hydrogel that can be used as drug-loaded materials. The results of morphological structure of the extracted gelatin powders derived from Tilapia scales using lime juice as natural acid in the extraction process showed ap…
PLLA-modified cellulose nanocrystals (CNC) were produced from commercial CNC by tin-catalyzed polymerization of lactide in presence of CNC. FTIR spectroscopy demonstrated that the result of the reaction produced the grafting of PLLA chains onto CNC surface (CNC-g-PLLA). Films of poly(lactic acid) (PLA) and PLA/CNC nan…
The eco-friendly aqueous electrosynthesis of AgIn <sub>5</sub> Se <sub>8</sub> (AISe) nanocrystals (NCs), and their respective core/shell structure AgIn <sub>5</sub> Se <sub>8</sub> /ZnS NCs (AISe/ZnS), was carried out by using <sc>l</sc> -glutathione (GSH) as a stabilizer.
The corrosion inhibition effect of non-toxic calcium gluconate at 0.75%, 1.25%, 1.75% and 2.25% concentration on mild steel in artificial seawater (3.5% NaCl) was studied by potentiodynamic polarization, coupon measurement, optical microscopy characterization and open circuit potential measurement. Results obtained sh…
In this work, a series of Ga1-xAlxFeO3 (x = 0, 0.1, 0.2, 0.5) nanoparticles was prepared by a modified Pechini method. The influence of Al doping at the Ga site on the structural, magnetic, and magnetodielectric (MD) properties of GaFeO3 nanoparticles was studied. The X-ray diffraction pattern analysis using the Rietv…
Abstract Duplex stainless steels combine excellent mechanical properties with good corrosion resistance. Consequently, they are in frequent use in various highly demanding applications, like Oil & Gas, chemical processing, pulp and paper, and desalination plants. Due to their high alloying contents, super and hype…
Chemoresistance is a common property of tumor-initiating cancer stem-like cells. Overcoming chemoresistance, particularly in cancer stem-like cells, can markedly enhance the efficacy of cancer therapy and prevent cancer recurrence and metastasis. This study demonstrates that temperature-negative expansion nanodrugs co…
Microbial contamination remains a significant issue for many industrial, commercial, and medical applications. For instance, microbial surface contamination is detrimental to numerous aspects of food production, infection transfer, and even marine applications. As such, intense scientific interest has focused on impro…
