This calls into question what the appropriate ‘effective size’ of nanoparticle aggregates is.
The results showed that urea affects both Fe2O3 morphology and particle size.
Results show that the size and morphology of the NiO nano-particles are dependent upon the particles size of compound 1.
The experimental results prove that nano-particle size can be measured reasonably by using the self-mixing effect technique combined with the improved projection algorithm.
We found that AUC yielded equivalent particle size distribution data to other nanoparticle characterization techniques, while also providing important information not probed by techniques such as DLS regarding the relative size of the particle core and shell components and the overall effective particle density.
The model provides the optimum nano-particle size for a specific application, which eliminates the performance loss due to the limited mass transportation.
The correct incorporation of finite size effects is important for distinguishing and quantifying the structural consequences of small particle size in nanomaterials.
An increase of capacity is expected to be reached by further reduction of the particle size and size spread as well as by optimizing the conductive coating of the nano particles.

It seems that the nano-form rather than the bulk form of the chemicals pass the BBB, and that there is an inverse relationship between particle size and the ability to penetrate the BBB.

What is the urea?5 answersUrea is a polar, hygroscopic molecule that is produced by the human body and is essential for maintaining skin hydration. It has been used in dermatology for over a century and is known for its moisturizing and keratolytic properties. Urea is a component of the natural moisturizing factor (NMF) in the epidermis and plays a role in regulating gene expression in keratinocytes, which is important for skin barrier function and antimicrobial defense. It has been used topically to treat various skin conditions such as xerosis, atopic dermatitis, ichthyosis, and psoriasis. Urea-containing formulations are available in different concentrations and have been shown to improve skin hydration, thin hyperkeratosis, and enhance the penetration of topical drugs. Urea-based products are generally well tolerated with mild side effects.
Does urea have an effect on obesity?5 answersUrea does not have a direct effect on obesity. However, there is evidence to suggest that obesity can lead to impairments in vital intracellular organelles such as mitochondria, and chronic inflammation and oxidative stress in obese individuals can further contribute to mitochondrial impairment. Additionally, obesity has been found to increase the risk of urethroplasty failure, with overweight and obese patients being more likely to experience failure compared to those with a normal body mass index. It is important to note that the relationship between obesity and urethroplasty failure is not linear, and severely or morbidly obese patients do not have an increased risk. While urea itself may not directly affect obesity, the normalization of urea clearance using size indicators like V can be influenced by obesity and gender, leading to mathematical distortions in the relationship between urea and creatinine clearances.
What is the effect of nano urea on the grain yield, protein content and nitrogen uptake of barley?5 answersNano-fertilizer application has been found to have a positive effect on the grain yield and its components of barley, including the number of spikelets and grains per spike, heavy grains per spike, 1000-grain weight, and overall grain yield. However, the effect of nano urea specifically on the protein content and nitrogen uptake of barley is not mentioned in the abstracts provided.
What is the particle size of cellulose nanofibers?5 answersCellulose nanofibers have different particle sizes depending on the source material and the extraction method used. Rice straw samples with particle sizes less than 75 μm yielded 27.19 ± 0.99% of cellulose nanofibers (CNF). Gel materials containing cellulose nanofibers have diameters of less than 100nm, less than 50nm, or less than 20nm. Cellulose nanoparticles with average particle diameters ranging from 70 to 365 nm were fabricated from cotton fibers. Porous structured particles composed of TEMPO-oxidized cellulose nanofibers (TOCNF) and magnetic nanoparticles have a high surface area and a highly negative charge. Cellulose-nanofiber-containing cellulose fibers have an average particle diameter of 2,000 nm or larger when dispersed in water.
How do you relate unit cell volume to the estimated crystallite sizes of a nanomaterial?3 answersThe unit cell volume of a nanomaterial can be related to the estimated crystallite sizes through various methods. General formulae have been derived that allow for the estimation of unit cell volume for all Bravais lattices. Additionally, the relationship between the mean crystallite size and the crystalline volume fraction has been studied. It has been observed that larger mean crystallite sizes tend to favor reduced crystalline volume fractions, possibly due to the ability of smaller crystallites to be randomly packed with a greater packing fraction. X-ray studies have also been conducted to obtain information about the microstructural properties of materials, including the size of coherently diffracting domains in crystals (crystallite size). These crystallite size characteristics can be used to ascertain an item's authenticity, study ancient metal treatment methods, and provide time and place correlations in archaeological research.
