Low Molecular Weight Organic Composition of Ethanol Stillage from Sugarcane Molasses, Citrus Waste, and Sweet Whey Abstract Filtered stillage from the distillation of ethanol made by yeast fermentation of sugarcane molasses, citrus waste, and sweet whey was analyzed by gas chromatography/mass spectroscopy and by high-performance liquid chromatography. Nearly all of the major peaks representing low molecular weight organic components were identified. The am jor components in cane stillage were, in decreasing order of concentration, lactic acid, glycerol, ethanol, and acetic acid. In citrus stillage they were lactic acid, glycerol, myo-inositol, acetic acid, chiro-inositol, and proline. -
Conformational Analysis of Molecular Chains Using Nano-Kinematics
Conformational analysis of molecular chains using Nano-Kinematics y z Dinesh Mano cha Yunshan Zhu William Wright Computer Science Department UniversityofNorth Carolina Chap el Hill, NC 27599-317 5 fmano cha,zhu,[email protected] Fax: 919962-179 9 Abstract: We present algorithms for 3-D manipulation and conformational analysis of molecular chains, when b ond length, b ond angles and related dihedral angles remain xed. These algorithms are useful for lo cal deformations of linear molecules, exact ring closure in cyclic molecules and molecular emb edding for short chains. Other p ossible applications include structure prediction, protein folding, conformation energy analysis and 3D molecular matching and do cking. The algo- rithms are applicable to all serial molecular chains and make no asssumptions ab out their geometry. We make use of results on direct and inverse kinematics from rob otics and mechanics literature and show the corresp ondence b etween kinematics and conformational analysis of molecules. In particular, we p ose these problems algebraically and compute all the solutions making use of the structure of these equations and matrix computations. The algorithms have b een implemented and p erform well in practice. In particular, they take tens of milliseconds on currentworkstations for lo cal deformations and chain closures on molecular chains consisting of six or fewer rotatable dihedral angles.

A 1 Case-PR/ }*Rciofft.;Is Report
.A 1 case-PR/ }*rciofft.;is Report (a) This eruption site on Mauna Loa Volcano was the main source of the voluminous lavas that flowed two- thirds of the distance to the town of Hilo (20 km). In the interior of the lava fountains, the white-orange color indicates maximum temperatures of about 1120°C; deeper orange in both the fountains and flows reflects decreasing temperatures (<1100°C) at edges and the surface. (b) High winds swept the exposed ridges, and the filter cannister was changed in the shelter of a p^hoehoc (lava) ridge to protect the sample from gas contamination. (c) Because of the high temperatures and acid gases, special clothing and equipment was necessary to protect the eyes. nose, lungs, and skin. Safety features included military flight suits of nonflammable fabric, fuil-face respirators that are equipped with dual acidic gas filters (purple attachments), hard hats, heavy, thick-soled boots, and protective gloves. We used portable radios to keep in touch with the Hawaii Volcano Observatory, where the area's seismic activity was monitored continuously. (d) Spatter activity in the Pu'u O Vent during the January 1984 eruption of Kilauea Volcano. Magma visible in the circular conduit oscillated in a piston-like fashion; spatter was ejected to heights of 1 to 10 m. During this activity, we sampled gases continuously for 5 hours at the west edge. Cover photo: This aerial view of Kilauea Volcano was taken in April 1984 during overflights to collect gas samples from the plume. The bluish portion of the gas plume contained a far higher density of fine-grained scoria (ash). -
Fine Tuning the Hydrophilic–Hydrophobic Balance in Inositols Through Annulation: an Analysis of the Hydrogen-Bonded Architectures of ‘Annulated Inositols’

Thus, while cyclohexa- annulated myo- and chiro-inositols exhibit a head-to-head bilayer molecular assembly, consisting of dimeric or octameric columnar architectures, cyclopenta-annulated chiro-inositol shows no such aggregation of the hydrophilic and hydrophobic faces, rather preferring to pack in a manner akin to a hydrophilic inositol. The differences in the two packing modes can be attributed to the size of the hydrocarbon ring, fine-tuning the hydrophilic–hydrophobic balance in the annulated inositols. An analysis of the non-polar molecular surface area (a measure of the intermolecular hydrophobic van der Waals interactions) for all the annulated inositols under study further vindicates the conclusion. Introduction alicyclic ring, could serve as a handle to fine tune the hydrophilic–hydrophobic balance in the otherwise polar Cyclohexane-1,2,3,4,5,6-hexol, in all its nine stereoisomeric inositols. This could in principle serve as a means of forms, constitutes a group of biologically important entities, modulating the cell membrane permeability and receptor 1 commonly known as inositols. -

Unit 1 – Atomic Structure and Nuclear Chemistry Introduction to the Atom
Unit 1 – Atomic Structure and Nuclear Chemistry Introduction to the atom Modern Atomic Theory All matter is composed of atoms Atoms cannot be subdivided, created, or destroyed in ordinary chemical reactions. However, these changes CAN occur in nuclear reactions! Every atom has different properties from other atoms Ex: grinding down a gold ring Modern Atomic Theory Wait, it’s “only” a theory? Why are we learning it then? •A theory is a powerful term in science Theory -A set of tested hypotheses that gives an overall explanation of some natural phenomenon. Ex: Cell theory & Evolutionary theory We can now see atoms …sort of In 1981 a STM (Scanning Tunneling Microscope) was created. - We can see them and manipulate them. The Kanji characters for "atom." This image was formed by using the tiny tip of an STM to pick up individual atoms of iron and place them on a copper (111) surface. Nanotechnology is coming Atoms can be moved and molded to make various devices such as molecular motors Structure of the Atom Accessing Prior Knowledge 1. Based on your previous science classes, draw a generic atom and label where you’d find the nucleus, protons, neutrons, & electrons. 2. For a common beryllium atom, what is the: a) # protons? b) # neutrons? c) # electrons? Structure of an Atom Electrons (in electron cloud) 1/2000th the mass of P+ & N Nucleus (protons + neutrons) Particle Charge Mass Location Purpose # Electron -1 0 Electron Behavior of cloud element Proton +1 1 Nucleus Identity of element Neutron 0 1 Nucleus Stability of nucleus Charges in an Atom The atom is generally neutral because: # of negative electrons = # of positive protons The nucleus is positively charged because: Contains positive protons (and neutrons which don’t have a charge). -

The solid acid supported on silica gel and then as an effective catalyst in Friedel-Crafts alkylation of alcohols and aromatic compounds was used. The reaction progress was controlled using thin layer chromatography and the reaction products were analyzed using IR spectroscopy devise. The results show this new catalyst is effective in the friedel crafts alkylation and C-C bond formation was done in short time with very good yields. Keywords: Catalyst, Cellulose sulfuric acid, Friedel-Crafts alkylation, Silica gel. Introduction Catalysts are compounds that can speed up chemical reactions, but they do not participate in it. From Different types of catalysts can be named acidic catalyst that would have used a lot in many chemical reactions. These compounds have many applications in various chemical 1-7 reactions . The acid catalyst that is commonly used, are based on acids such as HF, H2SO4, HCLO4, H3PO4.
