2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are

titration curve with the pKa values and pI point and molecular weight were either directly or indirectly found through the titration curve. INTRODUCTION Amino acids are also known as the building blocks of proteins. They are constituted of the amine group –NH3‚ the carboxyl group –COOH‚ hydrogen and “R” group which is different for each amino acid. The “R” group gives the amino acid its name. in physiological systems where the pH is near neutrality‚ the amino acid will occur in its net charge

History: More Than 85 Years of Philippine Partnership Caltex gained its foothold in the Philippines in 1917 when Texas Company (as Texaco was then known) began marketing the products in the Philippines through a local distributor‚ Wise and Co. Four years later‚ Texaco (Philippines) was formally established and opened its office in Binondo‚ Manila. Eleven years later‚ its Pandacan warehouse depot was converted into a key distribution terminal to bring products by barge to nearby provinces. By 1936

Giuseppe Martello 1st year medical English of “Vasile Goldis” University Cranial Malformations Cranial defects are some of the most serious birth defects affecting children today‚ due to the potential for these birth defects to cause significant damage to the skull and brain. One of the most common types of cranial defects is a congenital malformation called craniosynostosis. In children born with craniosynostosis‚ the cranial sutures close earlier than normal‚ causing an abnormal growth

The results of the experiments carriedout for the degradation of fabric dyes from aqueous solution using Chara and Chara beads are discussed below.Various analytical techniques like UV-Vis‚ FTIR spectroscopy were used to confirm the decolorization as UV-Vis spectroscopy; FT-IR spectroscopy and toxicity bioassay were truly used [14]. Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]
