Summary: Pilling may be defined as a surface fabric fault comprising of circular accumulations of entangled fibers that cling to the fabric surface thereby affecting the appearance and handle of the fabric. The formation of pills occurs as a consequence of mechanical action during washing or wear. Pilling of fabric ch…
In the present study, the interaction of chitosan with β-cyclodextrin producing a complex in the solution was carried out by freeze drying method. An apparent stability constant of 370 M -1 and a 1:1 stoichiometric ratio were observed for the complex formed by using the phase solubility method. The complex was charact…
Objective: The aim of this study was to encapsulate vascular endothelial growth factor (VEGF) in poly(lactic-co-glycolic acid) (PLGA) microspheres using a water-in-oil-in-water emulsification method. Particle size distribution and surface morphology of PLGA microspheres and VEGF loaded PLGA microspheres were investiga…
This study presents a practical approach for estimation reflectance spectra by means of scanner. New methods were based on polynomial regression, neural network, neuro-fuzzy and principal component analysis techniques.
A major factor in the economic exploitation of geothermal resources will be the cost-effective selection of materials that have sufficient resistance to corrosion to maintain component integrity during plant operation. Various metals have been tested in laboratory and in-situ weight-loss exposure tests (Soultz-sous-Fo…
Mechanical properties of Al6061 alloys has necessitated the need for the development of newer alloys and metal matrix composites of Al6061 alloy. MMC’s are quiet popular in engineering applications because of low density and high stiffness. Carbon Nano tube to be an excellent reinforcement material for Al6061alloy bas…
A B ST R A C T The aim of the study was to investigate and compare antibacterial and antifungal activity of leaves extract taken from four different plants Quisqualis indica Linn., Calotropis procera Ait., Achyranthes aspera Linn., and Ocimum sanctum Linn. against ten microorganisms comprising of five bacteria ( Bacil…
Aeromonas hydrophila is a heterotrophic, gram negative bacterium which is primary or secondary cause of ulcers, fin rot, tail rot, and hemorrhagic septicaemia in fish. The treatments for this infection are only restricted to some antibiotics. So, novel materials are being searched for combating with bacterial infectio…
Available methods of cryochemical treatment for nanopowders and nanoceramics production were briefly described. The basics and theory of freeze-drying were discussed. Re- cent achievements and efforts in this field have been summarized. The proper choice of cryochemical treatment methods appeared to be the enough easy…
This paper describes a self-healing composite exhibiting high levels of healing efficiency under working conditions typical of aeronautic applications. The self-healing material is composed of a thermosetting epoxy matrix in which a catalyst of Ring Opening Metathesis Polymerization (ROMP) and nanocapsules are dispers…
Hair is an appendage of the skin that plays an important role in the beauty of people's face. Daily averages of 50 to 80 hairs are shed naturally. Various factors are effective in hair loss. In this paper using the eight influence attributes of gender, age, genetic factors, surgery, pregnancy, Zinc deficiency, iron de…
Bioleaching has become a research hotspot, as a simple and effective technology for metal extraction from low-grade ores. During the process of bioleaching, the chemoautotroph organisms play a key role. However, their growth and activity are greatly restrained by the stress brought by over acidic extracellular environ…
The area of technical textile applications is very wide, with one of the most important being medical textiles. Polymer-iodine complexes (i.e. iodophors) are widely used in antiseptic products. Nanofibres with iodine may be used to disinfect skin in medicine, and iodine is also characterised by a fungicidal effect. Th…
A biosensor comprising tyrosinase immobilized on bifunctionalized multiwalled carbon nanotube (MWNT) supports was prepared for the detection of phenolic compounds in drinks such as red wine and juices. The MWNT supports were prepared by radiation‐induced graft polymerization (RIGP) of epoxy‐containing glycidyl methacr…
For bone tissue regeneration, composite scaffolds containing biodegradable polymers and nanosized osteoconductive bioceramics have been regarded as promising biomimetic systems. Polymer blends of poly(hydroxybutyrate‐co‐hydroxyvalerate) (PHBV) and poly(L‐lactic acid) (PLLA) can be used as the polymer matrix to control…
Gliclazide-loaded microparticles made with a polymeric blend were prepared by a solvent evaporation technique. Organic solutions of two polymers, poly (epsilon-caprolactone) (PCL) and Eudragit RS (E RS) or ethyl cellulose (EC), in different weight ratios, and 33.3% of GLZ were prepared and dropped into aqueous solutio…
Being able to predict the visual appearance of a painted steel sheet, given its topography before paint application, is of crucial importance for car makers. Accurate modeling of the industrial painting process is required. The equations describing the leveling of the paint film are complex and their numerical simulat…
Resting stage cells of six diatom species, Actinoptychus senarius, Biddulphia alternans, Lithodesmium variabile, Odontella longicruris, O. mobiliensis, and Detonula pumila were newly identified from bottom sediments of Ago Bay, central Japan. The resting stage cells of A. senarius, B. alternans and L. variabile are ve…
This work discovers that Cu2O nanocrystals with controllable structures can be synthesized on surfaces of nanoporous Cu and amorphous ribbons by free dealloying of Cu‐based amorphous alloys in acidic solutions. Technological parameters, such as the acid, acid concentration, and dealloying time strongly influence the c…
Ni(OH)2 nanoplates grown on Cu substrate were synthesized by a simple hydrothermal method. Au nanoparticles were dropped onto Ni(OH)2 nanoplates according to optimal ratio to get Au NPs–Ni(OH)2–Cu nanocomposites. These were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), transmissi…
