Polymeric materials often undergo large inhomogeneous deformations at high rates during their use in various impact-resistant energy-absorbing applications. For better design of such structures, a comprehensive understanding of high-rate deformation under various loading modes is essential. In this study, the behavior…
The aim of this study was to produce biopolymer-based nanocomposites using extrusion as an industrially adaptable manufacturing process, and to study how this production process influenced the structure and properties of the nanocomposites produced. Cellulose nanowhiskers (CNWs) were prepared and used as nanoreinforce…
Abstract Tissue engineering needs a biomaterial as a framework for single cells to build a vital and well functioning tissue. A future challenge is to modify biomaterials used this purpose in a way that they imitate in their composition and/or structure the native and physiological conditions for the tissue specific c…
Wool fabric is one of the fabrics normally suitable for autumn—winter garments. With the popularization of air conditioning, however, it is much hotter outdoors than indoors with a large temperature gradient in summer, under which circumstances the wearer finds it easier to sweat out of doors, and feels cold and clamm…
In engineering and materials science, nanotechnology has provided many advances that effectively reduce oxidative damage generated by free radical production. Despite such advances, there has been little application to biomedical problems. Increased oxidative stress and free radical production are associated with neur…
Abstract Delivery systems generated by reversible hydrazone formation from hydrazine derivatives (see Fig. 1 ) and carbonyl compounds in H 2 O efficiently increase the long‐lastingness of volatile aldehydes and ketones (R 1 R 2 CO) in various perfumery applications. The hydrazones are usually obtained in an ( E ) con…
Intermittent “on” and “off” (blinking) photoluminescence (PL) of single-CdSe/ZnS quantum dots (QDs) is modified when placed on an Ag nanoparticle (NP) film into stochastic fluctuations with nonzero intensity “off” (pseudo off) periods. Also, the PL quantum efficiency (from 0.42 to 0.22) and lifetime (from 5.2 to 1.5 n…
In this work, we present a short summary of the synthesis and characterization of superparamagnetic iron oxide nanoparticles and their behavior in vitro and in vivo. Therefore, we have used various characterization techniques to deduce the physical particle size as well as magnetic properties. It is shown that the par…
Studies involving small iron oxide cationic clusters, Fe m O n + ( m = 1, 2, n = 1−5), and their reactivity in the presence of CO at near thermal energies were conducted by employing a guided ion beam mass spectrometer. Observed reaction channels included CO oxidation and oxygen replacement by CO which are shown to be…
A series of monodispersed fluoroperovskite nanocrystals with the size 20 nm were synthesized and rare earth doped. A series of KMF 3:Yb 3+,Er 3+ (M = Mn, Zn, Cd, or Mg) up-conversion phosphor nanocrystals were synthesized. The emissions can be directly observed using the naked eye. Different red-to-green luminescent r…
It has been possible to induce room temperature ferromagnetism, exhibiting high transition temperature, in tin oxide thin films by introducing manganese in a SnO2 lattice. The observed temperature dependence of the magnetization predicts a Curie temperature exceeding 550 K. A maximum saturation magnetic moment of 0.18…
The kd – βd (dispersion) equations are found for traveling waves on two‐ and three‐dimensional infinite periodic arrays of small lossless acoustic monopoles, electric or magnetic dipoles, and magnetodielectric spheres. Using Floquet mode expansions and then expressions for the rapid summation of Schlömilch series, pro…
In relation to the engineering of compression resistant thermal insulation materials, an unconventional application of hydroentangling technology is introduced in which, lightweight, wool webs are mechanically attached to one side of preformed knitted spacer fabrics to partially occlude the underlying apertures. In co…
PURPOSE: S-CKD602 is a STEALTH liposomal formulation of CKD-602, a camptothecin analogue. The cytotoxicity of camptothecin analogues is related to the duration of exposure in the tumor. STEALTH liposomal formulations contain lipid conjugated to methoxypolyethylene glycol and have been designed to prolong drug circulat…
Electrospinning is an enabling technology that can architecturally (in terms of geometry, morphology or topography) and biochemically fabricate engineered cellular scaffolds that mimic the native extracellular matrix (ECM). This is especially important and forms one of the essential paradigms in the area of tissue eng…
A novel tetrameric cluster, (enH2)3.5H15[{FeIIFeIII12(mu3-OH)12(mu4-PO4)4}(B-alpha-PW9O34)4].83H2O (1; en = ethylenediamine), has been hydrothermally synthesized and characterized by IR, optical diffuse reflectance, thermogravimetric analysis, and single-crystal X-ray diffraction. The skeleton of 1 is composed of four…
The accuracy of the Green–Kubo formulation for computing shear viscosity from equilibrium molecular dynamics simulations depends on the quality of the potential and on how the viscosity computation is carried out. We examine the role of the duration of the simulation, the number of particles used, and how the correlat…
Research on nanocomposite materials aims at developing nanoscale composites with innovative optical, chemical, and magnetic properties, all combined in one single nanostructure. In this scenario, nanostructures which show simultaneously fluorescent and magnetic features are of particular interest for pharmaceutical an…
A new modular concept for the self-assembly of electron donor-acceptor complexes is presented that ensures (i) fine-tuning the strength of the complexation, (ii) controlling the electronic coupling to impact electron and energy transfer processes, and (iii) high solubility of the corresponding hybrid architectures. Th…
