The optical properties of C\Mg, nano-rods produced by the explosion wire technique

The aim of this research is to study the optical properties of carbon-magnesium plasma resulting from arc discharge with explosive wire technique, where the energy gap of each of carbon and magnesium and the carbon-magnesium bond for three values of the wire exploding current (50,75,100 amperes) was studied. It was found that the energy gap for each of carbon and magnesium decreases with increasing the current, the X-ray diffraction of magnesium and the carbon-magnesium suspension was studied, and FTIR of the carbon-magnesium suspended carbon was studied for three values of the exploding current (50, 75, 100 amperes) and the type of bonds for carbon and magnesium was determined. To obtain deeper insight about the morphology and size distribution of the nano rods obtained from the explosion of a magnesium strip in a carbon suspension images obtained from transmission electron microscope (TEM) image analysis confirmed that the formed nanomaterial is rod-shaped.

The Physical Properties and Applications of Gold Nanoparticles (Au NPs): Review

Nanoparticles of gold that for years have been recognized are the concept of an increasingly rising reports number and of promising for electronic, optical, magnetic, biomedical and catalytic applications in century of 21st. Because of Nanoparticles of gold stability, an interest in such research is a reason for performing the current work. There are various types of AuNPs: Zero-dimensional AuNps: quantum dots, spherical nanoparticles. AuNPs as 1-dimensional: nanowires, nano-rods, nano-belts, nanotubes. AuNPs as 2-dimensional: nano-plates of gold, nano-shell and, AuNPs as 3 dimensional: nano tadpoles of gold, nano- dumbbells of gold (AuNDs), AuNPs being spread, for example, nano-dendrites of gold, nano-pods, and nano-stars. Au NPs, in the field of medicine are investigated for several applications include vectors of drug delivery, agents of contrast, and therapy of localized heat, biomarkers of ultra-sensitive and more. AuNPs are very attractive material for biosensor, chemosensory, genosensor and immunosensor production

Sonochemical Synthesis of the Novel 1d Zig-zag Hg(Ii)-iodo Brigdged Metal-organic Coordination Compounds With Thiosemicarbazide Derivative Ligand

In the present research, a novel mercury (II) metal organic coordination compound, [Hg(Q)I2]n (Q = pyridine-4-carbaldehyde thiosemicarbazide) with nano rods shape was prepared applying an ultrasonic manner. The synthesized compound was determined with infrared spectroscopy (IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). In solid state the coordination polymer takes the appearance of a zig-zag 1D polymer. The coordination number of Hg (II) is four by one sulfur atom of organic ligand and three iodine atoms which two of iodine atoms are coordinated to other repeating units, and one of iodine is unattached. The zig-zag 1D chains interact with neighboring chains via poor interactions, making a 3D supramolecular metal organic polymer.

Manganese Sulphide Nano Rods grown inside Acacia Senegal Gum Hydrogels; A Biocompatible Nanofabrication for Enhanced Biological activities

The present work demonstrates the synthesis and biological properties of novel manganese sulphide (MnS) hydrogels using acacia Senegal gum (ASG) as a natural biopolymer and divinyl sulfone (DS) as a cross-linker via in situ reduction method. Acacia Senegal Gum hydrogel p(ASG) and manganese sulphide (MnS) nano-rods fabricated hydrogels p(ASG)-MnS hydrogels were then characterized through various techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-Ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy, and thermogravimetric analysis (TGA). Biomedical investigation of pristine and p(ASG)-MnS was carried out by evaluating their biocompatibility, antioxidant and antidiabetic activities. Both the pristine and hybrid hydrogel shown excellent biocompatibility with 0.759 % hemolysis for p(ASG) and 2.386 % haemolytic activity for p(ASG)-MnS at the highest tested dose of 400 µg/mL. Furthermore, p (ASG)-MnS displayed remarkable antioxidant activities as evaluated by multiple antioxidant assays. The p(ASG)-MnS exhibit better DPPH and ABTS scavenging activities of 66.91±0.22 (%) and 98.40±0.58 (TEAC), respectively. On the other hand, p (ASG) showed 7.5%±0.58 (%) FRSA and 4.40±0.28 (TEAC), activity. Similarly, total antioxidant capacity (TAC) and total reducing power (TRP) values for p (ASG)-MnS were 184.32±2.3 (µg AAE/mg) and 179.83±0.1.2 (µg AAE/mg), respectively thus proving the considerable antioxidant properties of the hybrid hydrogels. The antidiabetic activity of p (ASG) and p(ASG)-MnS hydrogels were examined by determining their alpha-amylase inhibition potential. The p(ASG)-MnS displayed average alpha-amylase with numerical value 16.7±1.4 (%) as compared to p(ASG) with very weak inhibition potential of 4.18±0.98 (%). To conclude, p(ASG)-MnS hydrogel have excellent biocompatibility and antioxidant potential and reasonable antidiabetic activity as compare to pristine p(ASG).
