Herein, we attempt to study the synthesis process of 3-mercaptopropionic acid (3-MPA) capped gold nanoparticles (Au-MPA) and optimize preparation colorimetric sensor based on localized surface plasmon (LSP) phenomenon compared citrate stabilized (Au-Citrate). Both Au-Citrate Au-MPA were prepared using reduction method. In our case, product shows red-wine color solution with a plasmonic peak at 527[Formula: see text]nm, while has 519[Formula: text]nm same solution. particles have spherical...
Carrageenan is a generic name for family of natural, water-soluble, sulphated galactans isolated from red seaweeds and exploited commercially. The biopolymer kappa carrageenan has been known to be used as electrolyte in electrochemical device since it shows good ionic conductivity characteristic. In this study, we attempt study the chemical, morphology, electric properties carrageenan. We developed free-standing film with addition ammonium chloride an organic battery prototype. prepared...
Emerging quantum technologies that critically require the integration of emitters on photonic platforms are hindered by control over their position, quantity, and scalability. Herein, we describe a facile strategy to deposit aqueous silica-coated dots (QDs) in template polymethyl methacrylate (PMMA) nanoholes leverages saturated ethanol vapor drop-casting subsequent lift-off template. Ethanol incorporation into water droplets during drying process reduces meniscus contact angle, which...
Gold nanoparticles (AuNP) has been used in a wide range of applications especially medicine and optoelectronic due to its localized surface plasmon resonance (LSPR) effect. LSPR observation AuNP solution shows that the plasmonic peak absorbance spectra lies visible light around 520 nm with deep red-wine color. The optical characteristic is controlled by size shape including functionalization. Our research focused on adsorption study 3-mercaptopropionate (3-MP) (AuMP) synthesized ligand...
Soybean production in Indonesia is very fluctuating and tends to decline. The availability of quality soybean seeds a problem being faced today. Phosphorus nutrient that plays role the formation fruits seeds. Boron involved germination pollen aim this research determine effect phosphate boron fertilizers on yield This was conducted from October 2023 March 2024 at Horticultural Seed Garden Tohudan, Colomadu District, Karanganyar Regency, Plant Production Laboratory, Faculty Agriculture,...
Localized surface plasmon phenomena of metallic nanoparticles could be utilized for sensing applications. As the particles in vicinity results a near-field coupling phenomenon, higher field enhancement factor increases sensitivity. In this research, we propose self-assembled and closely-packed Janus gold nanoparticle (AuNP) structure application molecular sensing. We utilize three-phase interfacial trapping Langmuir-Schaefer method fabrication AuNP layer. our case, dodecylamine (DDA) was...
This research was conducted at SMA Negeri 2 Tangerang Regency to investigate the impact of roleplay on enhancing speaking skills 11th-grade students. The study encompassed a population 72 students from classes 11 MIPA 1 and 2. Employing quantitative approach quasi-experimental method, data collected through classroom observations assessments. results this were analysed using SPSS 22, employing Wilcoxon model. analysis demonstrated that two-tailed test produced statistically significant...
Metallic nanoparticle-based material is currently implemented in many photonics-based applications such as biosensors, imaging, and color filter due to its remarkable properties called localized surface plasmon or LSP. Numerical methods are commonly used calculate the optical responses arising from nanostructure. However, a faster calculation can be provided by analytical methods. In this paper, we an based on dipolar approximation transfer matrix method of stacked-nanoparticles array...
