Bacterial cellulose (BC) is a biodegradable, non-toxic, natural substance that can be obtained by culturing bacteria. It approached in various ways from physical, chemical, and biological points. BC nanoparticles have been applied as lubricating additives to improve the load capacity, anti-wear, friction. The microcellular foaming process was created using technology based on saturation of poly...

Current methods for screening cell-material interactions typically utilize a two-dimensional (2D) culture format where cells are cultured on flat surfaces. However, there is a need for combinatorial and high-throughput screening methods to systematically screen cell-biomaterial interactions in three-dimensional (3D) tissue scaffolds for tissue engineering. Previously, we developed a two-syringe...

We will construct a morphological scale-space using closings at logarithmically sampled scales. From this, we derive a measure for the pore-size distribution. We will apply this method to images of food products, acquired using confocal microscopy, to demonstrate how it can be used to differentiate the microstructure of these products. The microstructures are responsible for important macroscop...

Abstract The application of light weight particleboard in furniture industry becomes more inevitable because the requirement to facilitate transportation and assembly by customer. Herein, a novel method for fabrication foaming was proposed, which is achieved adding azodicarbonamide (AC) agent into formulation that consist oven-dry poplar ( Populus alba ) particles (with moisture content about 4...

The proximate composition and functional properties of three edible mushroom (Ganoderma spp., Omphalotus olearius (DC.) Sing. and Hebeloma mesophaeum (Pers.) Quél.) flours used in Nasarawa state, Nigaria were investigated using standard analytical techniques. The samples contained crude protein in the range of 18.5% in Omphalotus olearius to 21.5% in Ganoderma spp. Crude fat varied with values ...

In this paper, the effects of limited hydrolysis on functional properties, as well as on protein composition of laboratory-prepared pea protein isolates, were investigated. Pea protein isolates were hydrolyzed for either 15, 30 and 60 min with recombined chymosin (Maxiren). The effect of enzymatic action on solubility, emulsifying and foaming properties at different pH values (3.0; 5.0; 7.0 and...

Polymer foams are difficult to characterise due rapidly evolving physical features from liquid porous solid. Swift changes in volume, porosity and moduli render many techniques challenging for the characterisation of foam curing during a manufacturing process. A technique that employs longitudinal speed sound an ultrasonic signal, informed by thermokinetic model, is proposed as situ, in-line, n...

Optical methods play an important role in process analytical technologies (PAT). Four examples of optical process and quality sensing (OPQS) are presented, which are based on three important experimental techniques: NIR absorption, luminescence quenching, and, as novel method, photon density wave (PDW) spectroscopy. Addressed is the evaluation of four process and quality parameters eminent in t...
