Open Access Material from the Blog NanoLeaves

Up to date, I have published papers on the topic of nanocellulose and cellulose nanocrystals. My research interested are more in defining innovative applications, from the technological point of view, for nanocelluloses, rather than working on the nanocellulose extraction and production. Here is a list of open access materials that I have produced so far,Continue reading “Open Access Material from the Blog NanoLeaves”

New paper “Improving 2D-organization of fullerene Langmuir-Schäfer thin films by interaction with cellulose nanocrystals” published on Carbon (Elsevier)

The paper Improving 2D-organization of fullerene Langmuir-Schäfer thin films by interaction with cellulose nanocrystals is the fruit of a collaboration between the Universities of Pisa, Bari, Salento, and Trieste and of the Basque Foundation for Science. The paper is an in-deep investigation on the ability of sulfated CNCs to assist the two-dimensional organization of fulleropyrrolidines atContinue reading “New paper “Improving 2D-organization of fullerene Langmuir-Schäfer thin films by interaction with cellulose nanocrystals” published on Carbon (Elsevier)”

About “Haze” in cellulose nanopaper

The opaqueness of standard paper originates from the presence of empty spaces among fibers: the presence of air and other fillers yields a material with a discontinuous refractive index. This causes scattering of light in the backward direction and is the reason why we cannot look through a sheet of paper. This limit represents, actually,Continue reading “About “Haze” in cellulose nanopaper”

The solarleaf project publishes outcomes on cellulose nanopaper modification on the journal Soft Matter

It was released today as a Just Accepted Manuscript the article “Tailoring water stability of cellulose nanopaper by surface functionalization”. The publication is a study on cellulose nanopaper topochemical functionalization, attained via dipping the nanopaper in an organic solution of acyl chlorides. The surface chemistry of cellulose nanocrystals represents a hot topic in the nanocelluloses research.Continue reading “The solarleaf project publishes outcomes on cellulose nanopaper modification on the journal Soft Matter”

Cellulose nanopaper as potential substrate for printed electronics

An optically transparent paper is appealing for a series of applications and can be attained by processing cellulose nanocrystals by standard paper-making procedures. The nano-dimensioned cellulose crystals produce a thin film with suppression of light scattering, thanks to the reduced dimension of interstices among nanofibers. The nanofibers can be obtained by a top-down approach fromContinue reading “Cellulose nanopaper as potential substrate for printed electronics”

Ashby plots help comparing properties and potentialities of natural materials

Evaluation of materials properties for a selected application necessarily requires a method to compare different material sources. This is particularly true in the case of natural materials, those biocompatible and renewable constituents that can be extracted from biologic tissues. Natural materials often come in the form of composites. Just think, for instance, about a humanContinue reading “Ashby plots help comparing properties and potentialities of natural materials”

About cellulose

Formal discovery of cellulose, the structural material of plants, dates 1838 in the work of Anselme Payen,1 a French chemist also known for the discovery of the enzyme diastase. Cellulose technological importance is mainly connected to paper industry, even if cellulose derivatives, like rayon and cellophane, are part of our life for decades. Additional challengesContinue reading “About cellulose”

Why Nanopaper?

Considering the outmost attention put by the European Community on biodegradable and renewable plastics, the cellulose nanopaper (CNP), consisting of transparent and flexible paper sheets that are completely biodegradable, can find straightworward technological application in packaging, coating and many other applications. Nanopaper is a self-standing transparent film, that can be produced by deposition of nanocellulose crystals or fibers. With regard to chemicalContinue reading “Why Nanopaper?”
