We show that dislocations located at the edge of graphene cause different lattice deformations to those located in the bulk lattice. When a dislocation is located near an edge, a decrease in the rippling and increase of the in-plane rotation occurs relative to the dislocations in the bulk. The increased in-plane rotat…
The difference in the dielectric nonlinearity was investigated by contrasting BaTiO3 and (Ba0.925Ca0.075)TiO3 multilayer ceramic capacitors utilizing the first order reversal curve (FORC) distribution based on the Preisach model. Ca incorporation caused a decrease of the dielectric constants in the low field but littl…
Developing compounds regulating amyloid toxic oligomer but not fibril formation should constitute an effective strategy for the treatment of diabetes. Based on the full understanding of the folding mechanism, we designed an orthosteric helix regulator that can promote hIAPP to assemble into large non-cytotoxic oligome…
Alkyl-terminated silicon nanoparticles (SiNPs) were prepared through reactive high-energy ball milling with contamination of iron from the steel milling materials. Iron impurities in the form of iron nanoparticles cause a decrease of photoluminescence intensity and an increase of the UV absorption. The iron impurities…
The rapid growth in the cosmetic industry across the world is mainly due to the application of nanoingredients in cosmetics to enhance their properties and invention of new nanomolecules. Also, the weaker regulations on the application of nanoparticles as cosmetic ingredients and no safety assessment of cosmetics befo…
An original well-defined substitution algorithm on how to construct the icosahedral packings is proposed, simple inflation/deflation rules for icosahedral quasicrystals are described, and natural local matching rules are derived.
Amine-functionalized porous silicas (aminosilicas) are incorporated into latex coatings, and the airborne aldehyde abatement abilities of the dried applied films are examined. The aminosilicas in the resulting dried films are uniformly dispersed inside the latex component, and they are demonstrated to be effective ads…
High-resolution live cell microscopy will soon have a fundamental role in understanding bio-nano interactions, providing material that can be exploited using single particle tracking techniques. The present work uses 3D timelapse images obtained with confocal microscopy, to temporally resolve the co-localization betwe…
The AA′ 3 B 4 O 12 -type quadruple perovskite LaCu 3 Ir 4 O 12 prepared at high pressure (9 GPa) and temperature (1523 K) crystallizes in cubic symmetry ( Im 3̅, a = 7.52418(3) Å) with square planar CuO 4 and octahedral IrO 6 coordination as established from synchrotron powder X-ray diffraction studies. Both crystal s…
Tungsten-modified hydrogenated amorphous carbon coatings (a-C:H:W) were deposited on high speed steel by reactive magnetron sputtering of a tungsten carbide target in an argon-ethine atmosphere. The deposition parameters, sputtering power, bias voltage, argon and ethine flow rate, were varied according to a central co…
Recurrence of invasive breast cancer could arise from the residual cancer cells after comprehensive treatment. It is possible that residual invasive cancer cells are capable of forming highly patterned vasculogenic mimicry (VM) channels, leading to relapse and metastasis. In the present study, a new type of targeting…
Catalyst aging effects are analyzed using X-ray absorption micro-computed tomography in combination with conventional characterization methods on various length scales ranging from nm to μm to gain insight into deactivation mechanisms.
Perovskite oxides have attracted both experimental and theoretical attention due to their high permittivities, with SrTiO 3 used in waveguides, high capacity computer memory cells and dielectric elements in electronic devices. Different growth methods yield various qualities of material, and thin-films growth using or…
A versatile addition-crosslinking route is developed to transfer various hydrophobic nanocrystals into water. By assembling amphiphilic ligands and then crosslinking through 'click chemistry', a monolayer of polymer forms on the nanocrystal surface, leading to excellent stability and limited increase in hydrodynamic d…
Photoexcitation usually drives the LaAlO3/SrTiO3 interface from the insulating state into a totally metallic state, without experiencing any intermediate states. Here, we reported on an illumination-induced transition of the insulating LaAlO3(3uc)/SrTiO3 interface to a series of state between a totally insulating stat…
Photoisomerization of an azobenzene moiety modulates the thermodynamic stability of hairpin ODNs by interfering with stacking interation between azobenzene and neighbouring base pair and dihedral angle of the neighbouring base pair.
Two novel cyclic azobenzenophanes (SC, RC) with functional handles have been synthesized efficiently by a Glaser coupling reaction. Through a Suzuki coupling reaction, alternating ring/linear polymers with rigid (conjugated)/flexible (unconjugated) bridges were obtained from the resultant cyclic azobenzenophanes. The…
The effect of coir surface modification on the compatibility of polypropylene (PP)/coir fiber (CF) composites, in the presence and absence of compatibilizer (maleic anhydride grafted polypropylene, PP‐ g ‐MA) was assessed. Chemical pulping of the fibers was performed with 2, 4, 8, and 12% NaOH solutions for a period o…
Polyurethanes (PUs) are one of the most versatile classes of polymers, and their demand as high-performance industrial materials continues to grow. In this work, new polyurethane acrylates were prepared from diglycidyl ether bisphenol A (DGEBA), substituted acrylic acids, and 4,4′-diphenylmethane diisocyanate using a…
Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic c…
