(1) Purulent conjunctivitis affecting newborn babies is not invariably due to the gonococcus but may be caused by streptococci, staphylococci, or even B. coli and B. proteus. (2) Blindness from this cause in England has been reduced from approximately 25 per cent. of all blind children in 1920 to 9 per cent. in 1940. (3) This improvement began when the use of the Crede method of prophylaxis wit...

Advances in friction materials are imposed on developing multiceramic reinforced hybrid nanocomposites with superior tribomechanical properties. The silver-based matrix metals gained significance various applications like bearing, ratchet, and electrical contacts due to their high frictional resistance good thermal chemical stability compared traditional metals. present research is develop cont...

Silver sintering joints and AuGe soldering are promising technologies for high temperature (>200 C ambient) power electronics packaging. This paper presents the implementation of two silver-sintering processes with the one hand micrometer-scale silver particles, and on the other hand nano-meter-scale particles. Two substrates technologies have been investigated: A12O3 DBC and Si3N4 AMB. After t...

Singly charged silver-cluster anions are produced in a laser vaporization source and transferred into a Penning trap. After size selection the clusters are subjected to an electron bath in the trap, which results in the attachment of further electrons. The relative abundance of dianions or trianions as a function of the clusters’ size is analyzed by time-of-flight mass spectrometry. Silver-clus...

"Reconstructed" gill epithelia on filter supports were grown in primary culture from dispersed gill cells of freshwater rainbow trout (Oncorhynchus mykiss). This preparation contains both pavement cells and chloride cells, and after 7-9 days in culture, permits exposure of the apical surface to true freshwater while maintaining blood-like culture media on the basolateral surface, and exhibits a...

Objective(s): Development of a nanobiosystem by using plant essential oils with green synthesized silver nanoparticles that present synergistic antibacterial activity for overcoming antibiotic resistance in pathogenic bacteria. Material and Methods: Essential oils (EOs) of Kelussia odoratissima and Teucrium polium extracted by hydrodistillation were analyzed by gas chromatography-mass spectrome...

We report the direct and self-selective synthesis of Ag nanowires (NWs) on graphene patterns through a modified citrate reduction reaction approach. High-density NWs were selectively formed only on the graphene areas, whereas NWs were not synthesized on the SiO2/Si and glass substrates. The size and density of the Ag NWs gradually increased with increasing reaction time and AgNO3 concentration....

Nanoparticles influence on genome is investigated worldwide. The appearance of somaclonal variation is a cause of great concern for any micropropagation system. Somaclonal variation describes the tissue-culture-induced phenotypic and genotypic variations. This paper shows the results of somaclonal variation in two resistance genes pectin methylesterase and Mlo-like protein in all tissue culture...

The joint research project MikroSol focuses on electrical and microstructural properties of screen printed front side silver contacts. Special attention is given to the contact resistance of the contacts as well as metallizationinduced recombination losses in the space charge region of the solar cell. Differently processed industrial solar cells were characterized by electrical measurements as ...
