Green synthesized metal NPs can potentially inhibit the proliferation of MCF-7 cells and trigger apoptosis through Bax/Bcl2 and caspase–cascade mediated mitochondrial dysfunction.
Abstract Thermal-insulation properties of textile materials play a significant role in material engineering of protective clothing. Thermal-insulation properties are very important from the point of view of thermal comfort of the clothing user as well as the protective efficiency against low or high temperature. Therm…
The enhancement of the low absorption cross section and widening of the absorption range of the RE ions in the UV-blue region is still a challenge to develop optical systems with high performance. In this work we synthesized Bi- and Er-codoped Y 2 O 3 nanocrystals by means of Pechini type sol–gel process. X-ray powder…
Environmental responsiveness is an appealing trait of emerging polymeric materials, as shown for a variety of pH-responsive drug delivery systems. The chemical versatility of the conjugation site and conjugate lability to physiologically relevant changes in pH will largely determine their applicability. Herein, we rep…
Copper sulfide (CuS) nanoparticles have been prepared by a facile sonochemical method using copper nitrate and thiourea as precursors. The X-ray diffraction analysis revealed the formation of hexagonal CuS. The Field-emission scanning electron microscope showed the formation of CuS nanoparticles with size in the range…
The number of patients requiring flat bone transplantation continues to increase worldwide. Cell transplantation has been successfully applied clinically; however, it causes another defect site and the time requirements to harvest cells and expand them are considerable. In this study, KLD12/KLD12-SP (KLD12+KLD12-subst…
Nanodiamonds functionalized with different organic moieties carrying terminal amino groups have been synthesized. These include conjugates generated by Diels-Alder reactions of ortho-quinodimethanes formed in situ from pyrazine and 5,6-dihydrocyclobuta[d]pyrimidine derivatives. For the quantification of primary amino…
A facile approach of fabricating a temperature-responsive coating capable of switching reversibly from being superhydrophobic to superhydrophilic is presented. The approach combines micromolding, layer-by-layer assembly of the polymer macroinitiators, and surface-initiated polymerization. Changing between superhydroph…
Using on-wire lithography to synthesize well-defined nanorod dimers and trimers, we report a systematic study of the plasmon coupling properties of such materials. By comparing the dimer/trimer structures to discrete nanorods of the same overall length, we demonstrate many similarities between antibonding coupled mode…
Abstract One of the biggest disadvantages of rigid polyurethane (PU) foams is its low thermal resistance, high flammability and high smoke production. Greatest advantage of this thermal insulation material is its low thermal conductivity (λ), which at 18-28 mW/(m•K) is superior to other materials. To lower the flammab…
Through many years, conventional material developments have emphasized on microstructural refinement and homogeneity. However, “Nano- and Homogeneous” microstructures do not, usually, satisfy the need to be both strong and ductile, due to the plastic instability in the early stage of the deformation. As opposed to suc…
EMI shielding effectiveness values of up to 19 dB are observed in LSMO nanomaterials.
The electric and dielectric properties of La 0.5 Ca 0.5−x Ag x MnO 3 (LCMO–Ag with x = 0 and x = 0.4) were investigated using the impedance spectroscopy technique.
Despite the fact that the outstanding properties of graphene are well known, the electrical performance of the material is limited by the contact resistance at the metal-graphene interface. In this study, we demonstrate the formation of "edge-contacted" graphene through the use of a controlled plasma processing techni…
Molecular hydrides of the rare-earth metals play an important role as homogeneous catalysts and as counterparts of solid-state interstitial hydrides. Structurally well-characterized non-metallocene-type hydride complexes allow the study of elementary reactions that occur at rare-earth-metal centers and of catalytic re…
Polymeric micelles are used as 'smart drug carriers' for targeting certain areas of the body by making them stimuli-sensitive or by attachment of a specific ligand molecule onto their surface. The main aim of using polymeric micelles is to deliver the poorly water soluble drugs. Now-a-days they are used especially in…
Energetics of CO 2 uptake by layered double hydroxides (LDH) of Mg and Al and their corresponding mixed metal oxides (MMO) of two different compositions (Mg/Al = 2:1 and 3:1) were investigated by gas adsorption calorimetry. The initial adsorption enthalpies for all the LDH and MMO are similar and in the range −90 to −…
Hydrogels formed by the self-assembly of peptides are promising biomaterials. Here we demonstrate that the final material properties of a bioactive self assembled peptide system can be determined via control over the assembly conditions.
The nature of Au cluster precursor and activation treatments affect catalyst activity in aerobic benzyl alcohol oxidation.
We demonstrate the tracking of the spin dynamics of ensemble and individual magnetic ferritin proteins from cryogenic up to room temperature using the nitrogen-vacancy color center in diamond as a magnetic sensor. We employ different detection protocols to probe the influence of the ferritin nanomagnets on the longitu…
