Abstract A TiC powder is synthesized from a micron-sized mesoporous metatitanic acid-sucrose precursor precursor M by a carbothermal reduction process. Control specimens are also prepared using a nanosized TiO2-sucrose precursor precursor T with a higher cost. The most salient differences of the two specimens are found in the TiC from precursor M demonstrating i a higher crystallinity based on the distinctive doublet peaks in the high-two-theta XRD regime and ii a lower specific surface area

Production of Ethanol by Fermentation and Distillation Reading and Other Preparation to be Done Before Lab Always read the background information and techniques book sections, watch videos of any starred techniques, and prepare your notebook before lab.

Procedure, Background, and Techniques: Sucrose synthesis Handout Techniques online videos: Watch the videos on Simple Distillation videos Watching these will save you a lot of frustration and time. Appropriate physical and hazard data for all of the substances used and produced in the lab including sucrose, calcium hydroxide, and ethanol.

Procedure for Fermentation only parts 1 and 2including a diagram of the fermentation apparatus. You will turn in the pages containing the purpose, reaction equations, and substances at the beginning of this lab period, but will not turn in the pages with the procedure until the end of the following lab period after the distillation.

Second Week - Simple and Fractional Distillation Procedure for distillations and rest of lab parts 3 through 9. Since you will be collected little to no data during the distillations, other than what is in the data table, you may run your procedure across the entire width of the paper. Set up a data table in your notebook at the end of the procedure section to record the volume and temperature during the distillations; do not cram your "table" into the margin of your procedure section.

These don't need to be done before lab, but are useful preparation for the lab test. Lab Notes Here is a link to a photo of the fermentation setup. Please take care with the condensers. They are fragile and expensive! The neck of the mL flask is small and hard to grip relative to its size; please support it with two hands.

Whenever possible use the heating mantle size that matches the flask size. Both mL and mL versions are available in Sci in the cabinets closest to the northeast corner. The setup for the simple distillation is in Figure Make sure your apparatus is stable.

Support your apparatus with utility clamps and Keck clips so that it doesn't come crashing down and cause you to lose your locker card money. Things will work out better if itthe flask is clamped just above the first horizontal bar, as that will provide enough room for the mL graduated cylinder on the other end of the apparatus.

Then add the still head, etc. It doesn't matter tremendously which condenser you use if you have a choice: If they are different lengths, use the longer one. The condenser just needs to be resting on the second utility clamp, or you can also use an iron ring for this pupose. Use Keck clips to secure the condenser to the glass pieces on either end.

Gravity is not your friend here Note that the thermometer adapter consists of two pieces--a glass one that fits in the top of the distilling head and a rubber piece that fits over that. Do this neatly and give it enough room--crammed into the margin is not good enough.

Once you have determined the density of your simple distillate part 5 of Procedure do not throw the distillate away as you will be using it as the starting point for the fractional distillation.

For the fractional distillation, see Figure If you have a fatter one, use that as the fractionating column. Whichever one you use for the fractionating column must be dry on the inside before you start. You may or may not be asked to pack the fractionating column with steel wool or glass beads.Sucrose synthesis in the cytosol and starch synthesis in the chloroplast are the major pathways by which the excess triose phosphate from photosynthesis is “harvested.” Sucrose synthesis releases four Pi molecules from the four triose phosphates required for its production.

In nonphotosynthetic tissue (roots), KO of NTRC decreased redox activation of AGPase and starch synthesis in response to light or external sucrose by almost 90%.

The results provide biochemical and genetic evidence for a role of NTRC in regulating starch synthesis in response to either light or sucrose.

The aim of this work was to evaluate the antibacterial activities and mode of action of sucrose monolaurate (SML) with a desirable purity, synthesized by Lipozyme TL IM-mediated transesterification in the novel ionic liquid, against four pathogenic bacteria including L.

monocytogenes, B. subtilis, S. aureus, and E. coli. The antibacterial activity was determined by minimum inhibitory. Particles is an international conference focused on particle formation, particle characterization, and particle-based materials synthesis.
