Nanoparticle

Nanotechnology is a science and engineering technology conducted at the nanoscale, which is 1 to 100 nanometers, so basically speaking it’s a manipulation or changing in matter. Some people have thought that that this revolutionary science has just been discovered, but it has been discovered ever since the 1950’s , yet the technology had finally called a study of science in the 1980’s paving the way of nanotechnology discoveries and advancements. However, many people are only aware of the…

3.3.9. Encapsulation efficiency of drug loaded NPs The encapsulation efficiency (EE) was determined by weighing the amount of unloaded drug recovered from lyophilization of the supernatant obtained after centrifugation of NPs. The drug encapsulation efficiency was calculated according to the following equation: Encapsulation efficiency (%) = (Winitial/Wfree)/Winitial *100%. Where, Winitial and Wfree are the weight of initial drug and the weight of free drug determined in the supernatant after…

They made use of all the moisture released into the atmosphere. An interesting thing happens when nanoparticles of moisture mix with particles of aluminum, barium oxide, and strontium. It becomes plasma! You might think those materials floating in the atmosphere are industrial pollution. That’s a mistake. The material is intentionally placed for a precise…

1. What was the average score you calculated for the lab? What does this number mean in terms of ergonomically correct workplace? a. The average score we calculated for the lab was approximately 6.9/10, and what this number means in terms of an ergonomically correct workplace is that the room is not very ergonomically correct. This marking scheme is similar to that of a test or assignment, in which 69%, despite it being a passing grade, has a lot more room for improvement. 2. Describe the…

A catalyst layer is usually the slimmest layer in a PEM fuel cell; however this is an extremely complex component because of its porosity, several phases, and reactions (Spiegel 2008). An efficient catalyst layer should provide several functions at the same time; transporting the electron and the proton, supplying oxygen and hydrogen and water management. The structure and composition of the catalyst layer affects all these roles. Optimization of the catalyst layer can provide for all these…

For the synthesis of P2, a mixture of 1 (500 mg, 0.553 mmol), 2 (252 mg, 0.553 mmol), 3 (760 mg, 1.105 mmol), tris(o-tolyl)phosphine (P(o-tol)3) (13 mg, 0.044 mmol), and tris(dibenzylidene acetone)dipalladium(0) (Pd2(dba)3) (10 mg, 0.011 mmol) in anhydrous chlorobenzene (21 mL) was charged in a 100 mL round bottom flask. The resulting reaction mixture was heated at 150 °C under stirring for 3 days. Compound (2) (38 mg, 0.083 mmol) was added and stirred at 150 °C for 1 h. To that…

In this research, mesoporous material KIT-6 silica with high surface area (924.5 m2/g) and pore diameter (9.71 nm) was successfully synthesized using rice husk ash as a silica source. According to the SAXS analysis and TEM micrographs, the silicate structure of as-prepared KIT-was not distrupted by the functionalization and activation treatments with 3-APTES and glutaraldehyde, but showed a significant decrease in pore diameter and total pore volume as the compound was covalently bonded to the…

cross-linked using reagents such as epichlorohydrin, diisocyanate, 1,4-butanediol digycidyl ether and glutaraldehyde [3, 7]. Chitosan can form a number of products from these reactions, including hydrogels, membranes, nanofibers, beads, micro/nanoparticles, scaffolds and sponges [1, 2,…

Cancer is a disease that arises from cells in a part of the body starting to grow out of control. It is one of the most common causes of death, taking nearly 7 million lives each year worldwide. Approximately one-half of men and one-third of women in the world are diagnosed with different cancer types at some point during their lifetimes. More than one-third of deaths occur within five years after a cancer diagnosis. As cancer comes to be a serious life-threatening disease to human, then, what…
