SYNTHESIS AND CHARACTERIZATION OF POLY (METHYL METHACRYLATE-STYRENE) COPOLYMERIC BEADS FOR BONE CEMENTS
Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads,
Synthesis of Hybrid Adsorbents Combining Sol-Gel Processing and Molecular Imprinting Applied to Lead Removal from Aqueous Streams
Two high-capacity thiol functionalized adsorbents are prepared, using sol−gel processing, and applied to the removal of lead(II) from aqueous streams. The first adsorbent (SN) is prepared by
UTILIZATION OF BY-PRODUCTS FROM THE TEQUILA INDUSTRY . PART 10 : CHARACTERIZATION OF DIFFERENT DECOMPOSITION STAGES OF Agave tequilana WEBBER BAGASSE USING FTIR SPECTROSCOPY , THERMOGRAVIMETRIC
Composting evolution of two different agave bagasse provided by two tequila factories was monitored at 0, 28, 56, 84, 112 and 126 days using Fourier transform infrared spectroscopy (FTIR),
Sisal Chemo-Thermomechanical Pulp Paper with a Strongly Hydrophobic Surface Coating Produced by a Pentafluorophenyldimethylsilane Cold Plasma
Fluorinated thin layers were created on CTMP sisal and filter paper surfaces by using pentafluoro- phenyldimethylsilane (PFPDMS) under RF-plasma condi- tions. Surface wettability and water absorption
Solid-state NMR studies of aminocarboxylic salt bridges in L-lysine modified cellulose.
TLDR
Comparison with the 13C and 15N chemical shifts of l-leucine lyophilized at different pH shows that the aminocarboxyl groups of LysCel are indeed zwitterionic, in contrast to the gas phase, where amino acid dimers exhibiting two OHN hydrogen bonds are neutral.
Polymeric hydrogels obtained using a redox initiator: Application in Cu(II) ions removal from aqueous solutions
Poly(acrylic acid-co-acrylamide) hydrogels were prepared via free-radical solution polymerization, crosslinked with ethylene-glycol-dimethacrylate, potassium persulfate/ammonium bisulfite as the
Unusual Hofmann Elimination under Mild Conditions in Polymerizable Cationic Surfactant Systems
Hofmann elimination and nucleophilic substitution reactions have been simultaneously observed at relatively low temperatures in a family of polymerizable alkyltrimethylammonium methacrylate
Phenacetin Isolated from Bursera grandifolia, a Herbal Remedy with Antipyretic Properties
TLDR
From the chloroform extract of leaves of B. grandifolia, a substance was isolated and identified as phenacetin, a well known compound with widely tested analgesic and antipyretic properties.
