A minor point[edit]

In the original Swedish version of the text, it seems to suggest that the main character has been smoking marijuana. I didn't include the reference to the drug... but any Swedish speaker could confirm whether or not this is the case. It doesn't seem tooo essential to the plot though ?

Gold & molybdenum nanoparticles,[edit]

Gold and molybdenum nanoparticles represent significant advancements in nanotechnology, offering unique properties that drive innovation across various industries. Gold nanoparticles, synthesized through the reduction of gold salts, exhibit exceptional biocompatibility and electronic properties, making them invaluable in biomedical applications, such as drug delivery and diagnostic imaging, as well as in electronics and catalysis. Molybdenum nanoparticles, produced via methods like chemical vapor deposition, excel in energy storage, lubrication, and environmental remediation. The research, spearheaded by Mr. KR SAM since 2010 and expanded in Canada from 2022, has developed robust processes for creating high-quality nanoparticle suspensions, paving the way for their widespread commercial use in enhancing product performance and sustainability.

Chemistry of Gold and Molybdenum NanoparticlesGold Nanoparticles (AuNPs)Gold nanoparticles are typically synthesized using gold salts and reducing agents in the presence of stabilizers. The chemical reactions involved in their synthesis and stabilization can be summarized as follows:Synthesis Reaction:Reduction of Gold Salts:Common gold salt: Hydrogen tetrachloroaurate (HAuCl₄)Reducing agent: Sodium citrate (Na₃C₆H₅O₇)Stabilizing agent: Sodium citrate (acts as both a reducing agent and stabilizer)The reaction can be represented as: [ \text{HAuCl}_4 + 3 \text{C}_6\text{H}_5\text{O}_7^{3-} \rightarrow \text{Au}^{0} + 3 \text{C}_6\text{H}_5\text{O}_7^{2-} + \text{HCl} ]In this reaction, hydrogen tetrachloroaurate is reduced to elemental gold (Au^0) by sodium citrate, which also stabilizes the formed nanoparticles by preventing agglomeration.Molybdenum Nanoparticles (MoNPs)Molybdenum nanoparticles can be synthesized using various methods, but a common chemical vapor deposition process involves the thermal decomposition of molybdenum hexacarbonyl (Mo(CO)₆).Synthesis Reaction:Thermal Decomposition of Molybdenum Hexacarbonyl:Molybdenum precursor: Molybdenum hexacarbonyl (Mo(CO)₆)The reaction can be represented as: [ \text{Mo(CO)}_6 \rightarrow \text{Mo} + 6 \text{CO} ]In this reaction, molybdenum hexacarbonyl decomposes upon heating to produce molybdenum (Mo) nanoparticles and carbon monoxide (CO) gas.Molybdenum Disulfide (MoS₂) NanoparticlesMolybdenum disulfide (MoS₂) nanoparticles, known for their lubricating properties, can be synthesized by the sulfurization of molybdenum trioxide (MoO₃) with hydrogen sulfide (H₂S).Synthesis Reaction:Sulfurization of Molybdenum Trioxide:Molybdenum precursor: Molybdenum trioxide (MoO₃)Sulfur source: Hydrogen sulfide (H₂S)The reaction can be represented as: [ \text{MoO}_3 + 3 \text{H}_2\text{S} \rightarrow \text{MoS}_2 + 3 \text{H}_2\text{O} ]In this reaction, molybdenum trioxide reacts with hydrogen sulfide to produce molybdenum disulfide nanoparticles and water.Colloidal SuspensionsThe nanoparticles are suspended in liquid mediums to form colloidal suspensions. These suspensions are stabilized by various surfactants or polymers to prevent the particles from aggregating.Gold Nanoparticle Suspension:Stabilizing agents: Polyvinylpyrrolidone (PVP), sodium citrate, or other surfactants.Molybdenum Nanoparticle Suspension:Stabilizing agents: Polyvinyl alcohol (PVA), polyethylene glycol (PEG), or other surfactants.These colloidal suspensions enable the practical application of nanoparticles in various fields, such as coatings, inks, and injectable solutions, ensuring uniform distribution and enhanced functional properties.By precisely controlling the synthesis and stabilization processes, Mr. KR SAM and his team have developed advanced materials with a wide range of industrial and scientific applications.
