Low-temperature graphene was synthesized at 400 degrees C with inductively coupled plasma chemical vapor deposition (PECVD) process. The effects of plasma power and flow rate of various carbon containing precursors and hydrogen on graphene properties were investigated with optical emission spectroscopy (OES). Various…
Generation 2 cationic carbosilane dendrimers hold great promise as internalizing agents for gene therapy as they present low toxicity and retain and internalize the genetic material as an oligonucleotide or siRNA. In this work we carried out complete in silico structural and energetical characterization of the interac…
W and W–H complexes on graphene on Ir(111) were studied by means of low temperature scanning tunneling microscopy. H is found to coadsorb at the sample surface during W evaporation. Five different W-related structures on graphene on Ir(111) were found and characterized. They are identified as WH n , with , as shown by…
ABSTRACT A novel hexa‐armed and star‐shaped polymer containing cholesterol end‐capped poly(ε‐caprolactone) arms emanating from a phosphazene core (N 3 P 3 ‐(PCL‐Chol) 6 ) was synthesized by a combination of ring‐opening polymerization and “click” chemistry techniques. For this purpose, the terminal OH groups of the s…
Protein is the functional actor of life. Research on protein damage induced by nanomaterials may give insight into the toxicity mechanisms of nanoparticles. Studying nano silver over the impact of the structure and function of catalase (CAT) at the molecular level, is of great significance for a comprehensive evaluati…
White and full-color displays based on upconversion (UC) processes in multilayered NaLu₁-x-yYbxTmy(WO₄)₂/NaLu₁-x-zYbxHoz(WO₄)₂ films deposited on 20 × 20 mm² Pyrex glass substrates are demonstrated by scanning with a 978 nm focused beam from a diode laser. Moreover, spatially resolved red, green and blue pixels are se…
An innovative composite recipe coupling binary mixtures of ammonium salts of ammonium formate and polar solvents 2-methoxyethanol has been successfully demonstrated as an effective surface-treatment reagent for significantly improving the thermoelectric performance of the baked poly(3,4-ethylenedioxythiophene):poly(st…
ABSTRACT Coaxial poly(ε‐caprolactone) (PCL)/gelatin nanofibers were successfully fabricated by electrospinning, using 2,2,2‐trifluoroethanol (TFE) as a solvent. The morphology of the PCL/gelatin coaxial fibers was evaluated using attenuated total reflectance Fourier transform infrared (FTIR) spectroscope, scanning ele…
In recent decade detonation nanodiamonds (DND), discovered 50 years ago and used in diverse technological processes, have been actively applied in biomedical research as a drug and gene delivery carrier, a contrast agent for bio-imaging and diagnostics and an adsorbent for protein separation and purification. In this…
Inspired by the anisotropy of the rice leaf surface, high‐speed wire electrical discharge machining (HS‐WEDM) technology was used to build submillimetre‐scale structures on the 304 stainless steel surfaces, and fluorination treatment was applied on the resulting surfaces. The wettability and microstructure of the resu…
Chemical vapor deposition (CVD) enables the mass synthesis of high‐quality nanotubes. There is a large number of synthesis process parameters that have an influence on the type and form of the final product. The aim of the paper is the optimization of the synthesis process of multiwalled carbon nanotubes (MWCNTs) with…
Localized Surface Plasmonics Resonance (LSPR) enhanced active photothermal effects of both aluminum nanoparticles (Al NPs) and iron nanoparticles (Fe NPs) are experimentally observed. Photothermally activated motion and ignition by low-energy xenon flash are quantitatively measured. For nanoparticles of comparable siz…
To obtain flexile poly(lactic acid)-based melt-blown nonwoven filtration material, poly(lactic acid)/poly(ϵ-caprolactone) melt-blown nonwoven with various components were melt-spun by melt-blown processing in the Melt-blown Experiment Line. The 3 wt.% tributyl citrate to poly(ϵ-caprolactone) was added in the composite…
The role of nanoclays and TiO2 nanoparticle loadings were investigated on low density polyethylene crystalline structure, in addition to studying packaging film properties such as barrier, thermal and mechanical properties. The polymer crystal study indicated for the orthorhombic crystal phase and about 20% lower degr…
Nanoplasmonic metamaterials are rapidly finding uses in optical devices. Self-assembled soft matter optical nanostructures are straightforward to manufacture and are low cost, self-healing, and tunable. The simplest way to self-assemble such structures is to bring nanoparticles to interfaces where they can build latti…
Fluorite structured nanocrystals of RbGdF4 in cubic symmetry have successfully been synthesized by employing a simple, one-step, and template-free wet chemical method at room temperature. Considering the structural model of cubic KLaF4 in the Fm̅3m space group, the observed powder X-ray diffraction (PXRD) pattern was…
Coronary artery disease is a great threat to human health and is the leading killer worldwide. Percutaneous coronary intervention is the most effective therapy; however, thrombus, and restenosis caused by endothelium injury continue to be problematic after treatment. It is widely accepted that surface biofunctional mo…
Vertically aligned carbon nanotubes (VA-CNTs) were grown on stainless-steel (SS) substrates by RF plasma enhanced chemical vapour deposition (PECVD). Adhesion of the CNTs to the substrate improves after treating the SS substrates with HF acid and adding an Al 2 O 3 layer of 20 nm that is required to support the metal…
This paper demonstrates that we can further eliminate the remaining micro pores by hot isostatic press (HIP) approach. The porosity of Nd:LuAG laser ceramics sharply declined from 7 x 10(-6) to 5.60 x 10(-7) after additional HIP. Annealing is one of the key steps to optimize the quality of vacuum sintered ceramics, su…
The understanding of disorder effects on crystallization is of fundamental and technological importance. It is well established by both theory and experiment that particle-size polydispersity hinders crystallization for isotropically interacting particles. Here, we address the effects of patch variability in a model f…
