LIQUIDI IONICI E CARBON DOTS UNITI NEI GEL IBRIDI!
La ricerca di materiali sempre più efficienti abbraccia svariati campi della società attuale e
l’unione di due componenti con peculiarità complementari può generare materiali altamente
innovativi. I gel formati da carbon nanodots e liquidi ionici non soltanto preservano le
caratteristiche dei singoli componenti, ma ne migliorano le prestazioni, generando così un
materiale ibrido performante e facilmente modulabile in base alle applicazioni richieste
Growth of central polynomials of algebras with involution
Let A be an associative algebra with involution ∗ over a field of characteristic zero. A central ∗-polynomial of A is a polynomial in non- commutative variables that takes central values in A.
Here we prove the existence of two limits called the central ∗-exponent and the proper central ∗-exponent that give a measure of the growth of the central ∗-polynomials and proper central ∗-polynomials, respectively. Moreover, we compare them with the PI-∗-exponent of the algebra
Oral History Interview, Carla Trujillo (1504)
In this interview, Carla Trujillo discusses her roots, which include being born in New Mexico and growing up in Northern California. Carla received her M.S. and Ph.D. degrees in Educational Psychology from UW-Madison and became an established author.

It will help determine which audio file(s) to download & listen to.Carla Trujillo was born to a working class family in New Mexico and grew up in Northern California. Her extended family and roots are New Mexican (Chicana). She received her B.S. degree in Human Development from UC Davis, and her M.S. and Ph.D. degrees in Educational Psychology from the University of Wisconsin, Madison. Her dissertation focused on assessing differential treatment of underrepresented students in college classrooms. She is the editor of Living Chicana Theory and Chicana Lesbians: The Girls Our Mothers Warned Us About (Third Woman Press), winner of a Lambda Book Award and the Out/Write Vanguard Award. Her first novel, What Night Brings (Curbstone Press 2003), won the Miguel Marmol prize focusing on human rights. What Night Brings also won the Paterson Fiction Prize, the Latino Literary Foundation Latino Book Award, Bronze Medal from Foreword Magazine, Honorable Mention for the Gustavus Meyers Books Award, and was a LAMBDA Book Award finalist. Carla has also written various articles on identity and higher education. Her latest novel, Faith and Fat Chances, was a finalist for the 2012 PEN Bellwether Prize for socially engaged fiction and is forthcoming from Curbstone/Northwestern University Press. Carla works as the Assistant Dean for Graduate Diversity Program at U.C. Berkeley and has focused some of her recent activities on improving the work and classroom climate using Interactive Theater. She has lectured in Ethnic Studies at U.C. Berkeley and Mills College, and in Women’s Studies at S.F. State University. She has also taught fiction for the Sandra Cisneros Macondo Writers Program and the Lambda Literary Foundation’s Emerging Writers Program

The upper triangular matrix algebra and its generalized polynomial identities
Let be the algebra of upper triangular matrices over a field of characteristic zero. Here we study the generalized polynomial identities of , i.e., identical relations holding for regarded as -algebra. We determine a set of two generators of the -ideal of generalized polynomial identities of and compute the exact values of the corresponding sequence of generalized codimensions. Moreover, we give a complete description of the space of multilinear generalized identities in variables in the language of Young diagrams through the representation theory of the symmetric group . Finally, we prove that, unlike in the ordinary case, the generalized variety of -algebras generated by has no almost polynomial growth; nevertheless, we exhibit two distinct generalized varieties of almost polynomial growth.12 page

Activity of a Heterogeneous Catalyst in Deep Eutectic Solvents: The Case of Carbohydrate Conversion into 5‐Hydroxymethylfurfural
Obtaining industrially relevant products from renewable resources and
developing processes under the light of sustainable chemistry is a prominent endeavor of
present-day chemical research. In this context, herein we investigated the dehydration of
fructose and sucrose in deep eutectic solvents promoted by the ion-exchange resin
Amberlyst 15 as heterogeneous catalyst. We optimized the reaction conditions in terms of
temperature, catalyst loading, and initial amount of substrate. Then, we looked at the effect
of structural variations in the solvent components on the reaction outcome. Under the best
experimental conditions, we obtained very good yields of 78% at 60 °C and 69% at 80 °C
for fructose and sucrose, respectively. Our catalytic system could also be reused for at least
five cycles without loss in yield. Finally, this study evidenced what structural features in the
solvent components lead to the highest yields
