Abstract Synthesis of silver nanoparticles was successfully synthesized by a chemical reduction method using nitrate (AgNO 3 ) as precursor and sodium borohydride (NaBH 4 reducing agent. The optical properties were studied based on their surface plasmon resonance (SPR) phenomenon UV-Visible spectrophotometry. absorbance spectra colloidal show the peak at wavelength range 380 nm to 450 nm. Collo...

This work describes the fabrication of silver-patterned polymeric devices via light-based 3D printing methods from a tailored resin. An acrylate resin containing silver nitrate (AgNO3) as precursor is employed to generate nanoparticles (AgNPs) through in situ reduction metallic salt. The silver-based processed customized stereolithography SL-3D fabricate structures with surfaces. SL-printer (em...

Abstract This work demonstrates the development of a highly sensitive and fast infrared photodetector using PbS thin film deposited simple scalable method known as “spray pyrolysis”. An aqueous precursor solution was on glass substrate at 150 °C have cubic phase PbS. Silver electrodes with 1 mm gap are drawn to create photo-detector devices. Low resistive contact between silver electrode is rev...

Abstract Attaining low-temperature sintering and high electrical conductivity is vital in the field of flexible electronics. Inks with silver oxalate as precursor have recently received significant attention this field; however, temperature long time limit commercial applicability. High can shorten but lead to porous uneven film morphology; thus, reducing conductivity. On other hand, low prolon...

Research has been carried out with the aim of studying formation functional groups a composite silver silica (Ag/ SiO2) based on rice husk and nitrate (AgNO 3 ) as precursor using sol-gel method. Variations in concentration AgNO used were 0,3M; 0,5M; 0,7 M thermal temperature 850 °C. The results Fourier transform infrared spectroscopy (FTIR) showed Si-O-Si, Si-O, O-N-O which result residue indi...

BACKGROUND The purpose of this study was to investigate the aging changes of macromolecular synthesis in animal cells. METHODS We studied 10 groups of mice during development aged from fetal day 19 to postnatal month 24. They were injected with 3H-leucine, a precursor for protein synthesis, sacrificed and the pancreatic tissues were taken out, fixed and processed for light and electron micros...

We present results of computational modeling of the formation of uniform spherical silver particles prepared by rapid mixing of ascorbic acid and silver-amine complex solutions in the absence of a dispersing agent. Using an accelerated integration scheme to speed up the calculation of particle size distributions in the latter stages, we find that the recently reported experimental results-some ...

Age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. Methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. The cells had greater affinity for diamine silver compared to methenamin...
