Photosystem I (PSI) is a membrane protein complex that generates photoinduced electrons and transfers them across the thylakoid membrane during photosynthesis. The PSI complex, separated from spinach leaves, was spread onto the air-water interface as a monolayer and transferred onto a gold electrode surface that was precoated with a self-assembled monolayer (SAM). The electrochemical properties of the transferred PSI monolayer, including cyclic voltammetry and photoinduced chronoamperometry, were measured. The results showed that PSI retained its bioactivity after the manipulation. Its capability of converting photoenergy into electrical potential was demonstrated by its reducing an electron acceptor, dichloroindophenol (DCIP), and by oxidizing an electron donor, sodium ascorbate (ASC). We have shown that the protein has two possible orientations at the water interface. The orientation distribution was determined by comparing the controlled reductive and oxidative photocurrents generated from Langmuir-Blodgett and Langmuir-Schaefer monolayers. © 2012 American Chemical Society.

Many algal extracts/preparations have been used in nutritional supplements and cosmetics for many decades, notably Dunaliella, Spirulina, Chlorella, Haematococcus, and numerous kelp species. However, the road to acceptance and use of preparations from new species is long, and there are many barriers to overcome. This article outlines what is needed to achieve acceptance from the perspective of a large marketer and manufacturer of a wide variety of consumer products. Real-life applications are used to show the required and desired information that must flow between the raw material supplier and the manufacturer to effectively bring a new material to the marketplace. The viewpoints of many different levels of the organization are considered including: product formulators with their focus on efficacy (of special interest are results from human clinical trials), mechanisms of action and performance of the ingredient in their formulations; quality assurance that looks for consistency and reliability of the ingredient; regulatory personnel that require assurance and documentation that an ingredient is acceptable in markets around the world; and procurement that requires adequacy of supply to fulfill market demand along with competitive pricing and reliable customer service. © 2011 Springer Science+Business Media B.V.

A sample digestion technique was developed using a mixture of nitric and hydrochloric acids that when combined form nitrosol chloride (4,5), an oxidative acid mixture commonly known as aqua regia. The zinc oxide samples were weighed into 50-mL digestion tubes containing 10% potassium iodide and 1 N iodine solutions; being careful to avoid sample contact with the sides of the tubes to ensure consistent results. Aqua regia digestion was initiated by first pipetting concentrated hydrochloric acid into the sample solution followed by concentrated nitric acid. The samples were heated for 10 min in a 100°C heat block, and then the digestion tubes were removed and allowed to cool to room temperature. A 30% solution of hydrogen peroxide was slowly added to the cooled sample and the digestion continued for 5 min in a 70°C heat block. The samples were again cooled to room temperature, and the 70°C digestion step was repeated two additional times, adding 2 mL of 30% hydrogen peroxide for the last sample digestion.. The results demonstrate that zinc oxide analysis using an aqua regia digestion method is a more efficient technique and provides equally accurate results compared to the fusion method. Source

A recurring order management system and method for a computer network is disclosed. The system receives a request to suggest a recurring order for one or more products or services. The system generates a profile which stores the suggested products or services, the suggested recurrence for those products or services and the suggested quantities to deliver upon each recurrence. The order then automatically recurs one or more times according to the specified recurrence.
