A series of acrylate‐based shape‐memory materials are synthesized from bisphenol A diacrylate monomers as crosslinking agents. Networks are synthesized by keeping constant the content of bisphenol A‐based crosslinking agent and systematically varying the content ratio of different monofunctional chain builder monomers…
The collapsing behavior of a bubble generated at the center of the rigid walls and its effect on the wall are investigated experimentally and numerically. The bubble collapse drastically depends on the ratio of the gap width to the maximum bubble radius w *. In case of 2.66 < w * < 1.17, by the decrease in w * to 2.5,…
Cavitation bubble collapse is influenced by nearby surfaces or objects. A bubble near a rigid surface will move towards the surface and collapse with a high speed jet. When a hard particle is suspended near a bubble generated by electric spark, the bubble expands and collapses moving the particle. We found that within…
In this work, a novel multifunctional rubber agent named as samarium lysine dithiocarbamate (Sm-LDC) was synthesized by a nucleophilic addition reaction and coordination reaction.
Low density polyethylene (LDPE), carbon black (CB), and oil palm empty fruit bunch (OPEFB) fiber composites were prepared by melt blending and compression molded into sheets. The effects of incorporated fibers on the electrical conductivity, thermal conductivity, tensile properties, and thermal degradation of the comp…
OBJECTIVES: To prepare a biomineralized nano silk fibroin film seeded with bone marrow stromal cells (BMSCs), and to evaluate its performance in spinal fusion. METHODS: The silk fibroin film was mineralized in a modified, simulated body fluid, seeded with BMSCs, and evaluated in a rat model of posterolateral lumbar fu…
A polyzwitterion is synthesized by regioselective functionalization of cellulose possessing a uniform charge distribution. The positively charged ammonium group is present at position 6, while the negative charge of carboxylate is located at positions 2 and 3 of the repeating unit. The molecular structure of the biopo…
The electronic structure and optical properties of orthorhombic CaTiO<sub>3</sub> have been investigated using the first principle projector-augmented wave (PAW) pseudopotential method. Exchange–correlation effects are treated by the generalized gradient approximation (GGA). The band structure and density of states (D…
Broadband dielectric/electric properties of multiwalled carbon nanotubes (MWCNT) polymethylmetacrylate composites were studied in a wide temperature range (25–400 K). It was established that the percolation threshold is lower in composites with the shortest MWCNT, due to the better distribution of the MWCNT in the pol…
In this paper, a new approach for metal-supported Solid Oxide Fuel Cell (SOFC) fabrication was investigated. Single cell with NiO and Fe 2 O 3 (Ni:Fe = 1:1) oxide support, NiO-Gd 0.1 Ce 0.9 O 1.95 (GDC) anode, GDC electrolyte and La 0.4 Sr 0.6 Co 0.2 Fe 0.7 Nb 0.1 O 3-δ (LSCFN) cathode was prepared through traditional…
The boson peak in deeply cooled water confined in nanopores is studied to examine the liquid-liquid transition (LLT). Below ∼180 K, the boson peaks at pressures P higher than ∼3.5 kbar are evidently distinct from those at low pressures by higher mean frequencies and lower heights. Moreover, the higher-P boson peaks ca…
Sepiolite (SEP) nanofibers have been modified by grafting with poly(pentaerythritol diphosphonate dichloride‐hexamethylendiamine) (PSPHD) and compounded with low density polyethylene (LDPE) to form a nanocomposite. The various modified SEPs were characterized by X‐ray photoelectron spectroscopy, Fourier transform infr…
We have performed structural properties, electronic properties, charge density and potential distribution of CsCaH3 and RbCaH3 using TB-LMTO-ASA approach under local density approximation. Our findings show that both CsCaH3 and RbCaH3 are non-magnetic and then insulators with estimated direct band gaps (M-M) of 3.15 e…
Two inorganic–organic hybrid compounds, (H2dabco-CH2-Cl)[MIICl4] (M = Co, Zn; H2dabco-CH2-Cl = 1-chloromethyl-1,4-diazabicyclo[2.2.2]octan-1,4-diium cation), were synthesized under slow evaporation conditions. DSC measurements indicated that compounds (H2dabco-CH2-Cl)[MIICl4] (M = Co, Zn) underwent reversible phase tr…
Abstract Wir stellen eine neue Methode zur Herstellung sehr kleiner aufwärtskonvertierender Kern/Schale‐Nanokristalle vor, die ohne zusätzliche Kodotierung der Kernpartikel auskommt und Partikel im Gramm‐Maßstab liefert. Durch die Reaktion von Natriumoleat, Seltenerdoleat und Ammoniumfluorid werden zunächst ca. 5 nm g…
Methylglyoxal (MGO) is a toxic, dicarbonyl metabolite in all living cells and its detoxification is regulated by glyoxalase I (GLOI). Herein, we rationally designed a precursor o-phenylenediamine-Phe-Phe-OH (1) which “click” reacts with MGO to yield amphiphilic methylquinoxaline-Phe-Phe-OH (2) to self-assemble into su…
Low-temperature hydrothermal reactions of copper salts with NaN3 and structurally related pyridine-based ligands, 1-(4-pyridyl)pyridinium, 3-chloromethylpyridine, 4-benzylpyridine, and quinoline (L(4)), respectively, led to the formation of four new magnetic complexes, [Cu3(L(1))2(N3)6]n (), [Cu3(L(2))2(N3)6]n (), [Cu…
Abstract We report an effective and universal approach for the preparation of ultrathin single‐ or multiple‐component transition‐metal hydroxide (TMH) nanosheets with thickness below 5 nm. The unique synthesis benefits from the gradual decomposition of the preformed metal–boron (M‐B, M=Fe, Co, Ni, NiCo) composite nano…
A novel aromatic fluorinated diamine monomer, 3,3′-diisopropyl-4,4′-diaminodiphenyl-4′′-trifluoromethyltoluene, was synthesized by coupling of 2-isopropylaniline and 4-(trifluoromethyl)benzaldehyde and its structure was confirmed by Fourier transform infrared spectroscopy, nuclear magnetic resonance, elemental analysi…
5-Fluorouracil (5-FU) is one among the anti-cancer agents in FOLFORINOX treatment along with oxaliplatin and irinotecan for the treatment of colorectal cancer. Despite its potential activity on the tumor cells, it lacks site specificity partly attributed by its biodistribution to healthy cells resulting in toxic effec…
