The Importance of Phosphate Levels (NaH2PO4) on Proper Arabidopsis thaliana Development Introduction Proper plant development is dependent on nutrient availability (Krouk et al. 2011). In this regard, plants can respond to nutrient availability by changing their root system architecture. In particular, phosphate (NaH2PO4) levels were found to affect the root system architecture in Arabidopsis thaliana (Williamson et al. 2001), which might impact overall plant development. A better understanding of plant nutrient requirements is important for the real world application of sustainable optimization of agricultural production for the human population (Reece et al. 2011). Arabidopsis thaliana has been extensively used as a research model in…

Where did phosphite come from? During WWII, rock phosphate was used as a white phosphorus incendiary and smoke screen. The shortage of rock phosphate concerned ag-officials and they began to look for alternative sources of phosphorus fertilizers. As a result, phosphonates were first considered as fertilizers in Germany and the United States during the 1930s and '40s. Rock phosphate is the beginning of most commercially made phosphorus products in the market today. Without the phosphate, many…

MIMICS OF DIPHOSPHATES Phosphate group: Phosphate is an inorganic salt of phosphoric acid or organophosphate is an ester of phosphoric acid. Organophosphate are important in ecology and biochemistry. Inorganic phosphates are used in industry and agriculture. Phosphates can condense to form pyrophosphates, at elevated temperature in solid state. Structure and chemical properties of phosphate group: The polyatomic phosphate ion consist of one phosphorous atom surrounded by four oxygen atom…

The overall objective of the experiment was to find the concentration of phosphate by using spectroscopy. Dilutions of a phosphate working solution with a known concentration were made and their absorption lengths were found using the spectrometer in order to find the concentration of the unknown phosphate sample. INTRODUCTION The goal of the experiment was to find the concentration of an unknown water sample using several standard phosphate solutions’ absorbencies and Beer’s Law. Knowing the…

Phosphate can be harmful when excessive amount is present in the drinking water system. The U.S. Public Health Service has set the maximum value of phosphate in drinking water at 3.0 mg/L. In this experiment, several samples were diluted and its concentration were analyzed through a spectrophotometer. The results obtained (0.1 mg/L and 2.28mg/L) are within the U.S. Public Health Service’s standards and are deemed to be safe. Introduction It is important that drinking water is monitored regularly…

Meta description: Potassium phosphate is a supplement that is used to treat or prevent hypophosphatemia. Potassium phosphate is an injection supplement used as a preventative in order to remedy low phosphorus in the blood. Overview Potassium phosphate is an intravenous injection used to prevent or treat hypophosphatemia, low phosphorus in the blood, through the use of a concentrated solution mixture of monobasic and dibasic potassium. Phosphorus occurs naturally in every cell in the body and…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

Hull aims to understand how Iron III phosphate (FEPO4) behaves under high temperatures and at which temperature would we start to observe structural transition of Iron III phosphate. As found by the researchers, the temperature where one is able to witness a structural change of Iron III phosphate, a transition from α-β would be at the temperature of 980K. As the researchers have highlighted, there have been substantial high temperatures experiments done on isotopes (AIPO4) and Quartz (SiO4).…

Iron phosphate structure with a symbol of FePo4, has crystal structures of FeO4 and PO4 as its tetrahedral links. There would be changes of this quartz type that can be determined by the neutron poly difraction between 294K and 1073K, according to Z. Kristallogr. While structural parameters of the iron phosphate depends on the temperature, whereby iron phosphate would be a beta-phase from an alpha-phase when temperature increases from low to high. Irregularity would also be affected by the…

The research paper first described the structural evolution of Iron Phosphate, FePO4 from temperature 294K to 1073K, in α phase and in its ß-quartz type. There are both similarities and differences in the crystal chemical relationship between quartz (SiO2) and FePO4. The structural parameters of α-FePO4 at low temperature range skews towards the parameter values for ß-quartz type when it is at high temperatures. Angles between elements Fe, O and P increase whilst tilt angles decrease…
