Ionic liquid facilitated approach to cellulosic ethanol production: improved biomass digestibility through ionic liquid pretreatment for ethanol production from cotton stalk

Ionic liquid pretreatment allows utilization of high substrate loadings in enzymatic hydrolysis of biomass to produce ethanol from cotton stalks Haykir, Nazife Isik; Bakir, Ufuk (Elsevier BV, 2013-11-01) To enhance the enzymatic conversion of cotton stalks to glucose at high substrate loadings and subsequently to produce ethanol, biomass was subjected to ionic liquid and alkaline pretreatments. Ionic liquid, 1-ethyl-3-methylimidazolium acetate (EMIMAc), which reduced biomass crystallinity, was effective in improving the conversion of cotton stalks to glucose (82-85%) regardless of the substrate loading used during enzymatic hydrolysis. On the other hand, the glucose yield decreased from 67% to 55% with an i...
Ionic conductivity of microporous titanosilicate ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method Galioglu, Sezin; Çam, İbrahim; Akata Kurç, Burcu (2017-09-15) Impedance spectroscopy was used to investigate the long-range ionic conductivity of the microporous, titanosilicate (Na,K)-ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method. To figure out the effect of grain boundary on ionic conduction, as-synthesized (Na,K)-ETS-10 films possessing different thicknesses of columnar grain structure (i.e., films prepared via 4h-, 6h-, 8h-, and 10h-growth) were tested. The conductivities of the films w...
Ionic strength-responsive poly(sulfobetaine methacrylate) microgels for fouling removal during ultrafiltration Çalılı, Fatma; Kaner, Papatya; Aro, Grace; Asatekin, Ayse; Çulfaz Emecen, Pınar Zeynep (2020-11-01) Zwitterionic materials have received a lot of interest in the field of membrane science and water treatment due to their excellent fouling resistance, super-hydrophilicity, and ionic strength response. However, they have typically been utilized for surface functionalization. In this study, we report the synthesis of zwitterionic poly(sulfobetaine methacrylate), p(SBMA), microgels, and demonstrate the effect of their ionic-strength responsive behavior on the extent and reversibility of fouling on ultrafiltra...
Ionic composition of lower tropospheric aerosols at a Northeastern Mediterranean site: implications regarding sources and long-range transport Koçak, Mustafa; Mihalopoulos, N (2004-05-01) Daily bulk aerosol filter samples were collected at Erdemli (36.6degreesN, 34.3degreesE) on the Mediterranean coast of Turkey for a 4-year period between 1996 and 1999. Concentrations of the water-soluble ions (Cl-, Br-, NO3-, SO42-, C2O42- MSA(-), Na+; NH4+, K+, Mg2+ and Ca2+) were measured in a total of 610 samples. In addition, three-dimensional (3-D), 3-day back trajectories of air masses arriving daily at Erdemli were calculated to determine potential aerosol source regions. The results indicated that ...
Electroactive macromonomers based on pyrrole and thiophene: a versatile route to conducting block and graft polymers Yagci, Y; Toppare, Levent Kamil (Wiley, 2003-10-01) The synthesis of block and graft copolymers containing insulating and conducting polypyrrole or polythiophene segments via a two-step procedure is described. Synthetic pathways to prepare pyrrole and thiophene functional macromonomers involving conventional and controlled/living polymerizations such as anionic and cationic ring opening, atom transfer radical polymerization are discussed. The use of these macromonomers in subsequent electrochemical and chemical polymerizations, leading to the formation of co...
