Abstract: The present invention refers to the use and creation of materials based on natural cellulose fibbers, synthetic fibbers, or mixed fibbers as physical support and storing medium or storage inducer of electrical and ionic charges in self-sustaining discrete or complementary field-effect transistors with non-volatile memory by using organic or inorganic active semiconductors for the manufacture of the channel regions that are deposited on the fibbers of the paper material as well as metals or passive semiconductors for manufacturing drain and source allowing the interconnection of fibbers, in addition to the gate electrode contact existing on the other side-face of the paper, p or n type respectively, in monolithic or hybrid forms.

Abstract: The invention illustrates an innovative way to fabricate low cost, efficient, rigid or flexible mesoscopic optoelectronic devices such as photovoltaic (PV) solar cells or photo sensors (b) comprising three-dimensional arrays of semi-conductive micro- or nano-pillars (3b) deposited from suspensions e.g. by inkjet printing. Said pillars additionally increase the surface area of the device composed of an interpenetrating network of semiconductor particles of mesoscopic (2-50 nm) size forming junctions. In the present invention the active surface area is significantly increased when compared to previous flat structures (a, 3a), being fabricated preferably by inkjet patterning. Additionally, the invention allows for production of much more functional devices when compared with conventional mesoscopic PV cells due to smaller structure density what makes the layer more resistive to mechanical failure when bending.

Abstract: This invention refers to a new method for optimizing the composition of cell culture media. This new method comprises two main stages. In the first stage, a functional enviromics map is built through the joint screening of cell functions and medium factors by the execution of a specific cell culture protocol and exometabolome assays protocol. The functional enviromics map consists of a data array of intensity values of elementary cellular functions against medium factors. In the second stage, optimized cell culture medium formulations are developed that either enhance or repress target elementary cellular functions from columns of the functional enviromics map.
