This article reports on preliminary studies of several comparative packaging properties between polyethylene terephthalate (PET) packaging films and biodegradable biopolymers such as polycarpolactone (PCL), polylacticacid (PLA), amorphous PLA (aPLA), and polyhydroxyalcanoates copolymer with 8 mol% valeriate (PHBV) and…
The direct intratumoral (i.t.) injection of anticancer agents has been evaluated extensively in the past few decades. Thus far, however, it has failed to become established as an alternative route of administration in routine clinical practice. In the present report, the impact of i.t. injection on the biodistribution…
Abstract The aim of this paper is to summarise recent progress in the growth of small grain‐sized Chemical Vapor Deposition (CVD) diamond often called nanocrystalline diamond, i.e., diamond with grains typically smaller than 500 nm. Nanocrystalline (NCD) and Ultrananocrystalline diamond (UNCD) films are new materials…
Cellular space charge polymer electrets significantly enlarge the basis of pyro- and piezoelectric as well as ferroic materials. Since the first review of the field has been published in this journal (R. Gerhard-Multhaupt, Less can be more: Holes in polymers lead to a new paradigm of piezoelectric materials for electr…
Two different fucoxanthin-chlorophyll protein complexes (FCP) were purified from the centric diatom Cyclotella meneghiniana and characterized with regard to their polypeptide and pigment composition. Whereas the oligomeric FCPb complex is most probably composed of fcp5 gene products, the trimeric FCPa has subunits enc…
To develop protective clothing for the paraplegic men their clothing related problems were identified by interview as well as observation method. A few paraplegic men encountered problems while wearing and removing upper garments for which help was always obtained. The problems encountered by all the respondents with…
We demonstrate all-optical wavelength conversion in AS2S3chalcogenide glass rib waveguides, with 6 ps pulses over a 10 nm wavelength range near 1550 nm. Frequency resolved optical gating (FROG) measurements show good converted pulse integrity in amplitude and phase in the frequency and time domains.
When two biopolymers are mixed together, they will normally phase separate to give two distinct phases. If the biopolymers are gelled during this phase separation, for instance by reducing the temperature, one phase is trapped in this other one and an emulsion-like composite structure is obtained. In this study, we in…
In this contribution, a brief review is given of the dynamics of emulsions in microconfined shear flow. The interest in confined flow is triggered by the increasing importance of microfluidic applications in the processing industries. In a first part, some important aspects of confinement on single droplet dynamics ar…
In this paper we describe the rheological behaviour of Ca2+-induced cold-set gels of whey protein mixtures. Cold- set gels are important applications for products with a low thermal stability. In previous work [1], we determined the state diagram for whey protein mixtures that were heated for 10 h at pH 2 at 80°C. Und…
The current computer simulation based study aims to elucidate the complex role that the state of aggregation and morphology of the food materials plays in determining their transport behaviour. Using Brownian dynamic simulations, applied to colloidal systems, we simulate the compression of two different dense layers o…
We provide an overview of transient extensional rheometry techniques for wheat flour doughs in which the deformation and material response is well defined. The behavior of a range of model doughs was explored with a Filament Stretching Extensional Rheometer (FISER). The measurements were also compared to data obtained…
We studied crystallization process of isotactic polypropylene (iPP) under shear flow as a function of shear rate using time-resolved wide-angle X-ray scattering (WAXS), small-angle X-ray scattering (SAXS), depolarized light scattering (DPLS), and polarized optical microscopy (POM) to elucidate the formation mechanism…
A facile means for obtaining submicrometer carbon fibers with a nanoporous structure is presented. A mixture of polyacrylonitrile (PAN) and a copolymer of acrylonitrile and methyl methacrylate (poly(AN-co-MMA)) in dimethylformamide was electrospun into submicrometer fibers with a microphase-separated structure. During…
Following the development of the glassy chalcogenide field, new optoelectronic materials based on these materials have been discovered. Several non-oxide glasses have been prepared and investigated in the last several decades, thus widening the groups of chalcogen materials used in various optical electronic and optoe…
This paper presents performance of supercapacitor built from different carbon materials. The general principle of supercapacitor and formula connected with its operation are also described. The role of carbon nanotexture has been underlined selecting carbons prepared by template techniques. It has been demonstrated th…
We investigate geometrically exact generalized continua of micromorphic type in the sense of Eringen. The two-field problem for the macrodeformation φ and the affine microdeformation P ̄ ∈ GL + (3, R) in the quasistatic, conservative load case is investigated in a variational form. Depending on material constants, two…
