Computers are organized into hardware and software. Using a theoretical approach to identify patterns in gene expression in a variety of species, organs, and cell types, we found that biological systems similarly are comprised of a relatively unchanging hardware-like gene pattern. Orthogonal patterns of software-like transcripts vary greatly, even among tumors of the same type from different individuals. Two distinguishable classes could be identified within the hardware-like component: those transcripts that are highly expressed and stable and an adaptable subset with lower expression that respond to external stimuli. Importantly, we demonstrate that this structure is conserved across organisms. Deletions of transcripts from the highly stable core are predicted to result in cell mortality. The approach provides a conceptual thermodynamic-like framework for the analysis of gene-expression levels and networks and their variations in diseased cells. [less ▲]

Palladium nanostructures are widely used as catalyst of many organic reactions1 and present intriguing and controversial magnetic properties. Since the direct experimental determination of ground state structure for small transition metal clusters is difficult, theory and first-principles calculations, such as density functional theory (DFT), have been used extensively to reveal the interplay between geometric and electronic structure. We present a theoretical study at the DFT/B3LYP level on three selected geometric arrangements for the Pd13 cluster with particular emphasis on the effects of thiolate and phosphine based ligands on their magneto-structural properties. The results point out that the interactions with ligands can change the relative stability of different structures of the metallic core, leading to the stabilization of the more compact icosahedral shape with respect to other bi-layer structures which are more stable in the free standing cluster. Beyond this structural evolution, the interactions with the ligand shell strongly modify also the electronic and magnetic properties of the metal core. In particular, both thiolate and phosphine ligands quench the high spin state that characterized the magnetic ground state of the bare Pd13 cluster, but while the interaction with phosphine quench the magnetic moment completely, the thiol-capped particles retain a permanent magnetic moment even when they are saturated by the ligand molecules. Our study suggests that different ligands can be effectively used to tune electronic and magnetic properties of Pd nanoparticles in view of the design and experimental realization of logic nano devices and intelligent sensors.

Semiconducting nanocrystals with tailored shapes have been widely investigated in the past decades because of their many shape-dependant properties. Anatase, a metastable phase of the titanium dioxyde (TiO2), is one of the most interesting material in many applications, such as photocatalysis, photovoltaics, photo/electrochromics or sensors. [1] In addition to an influence of the nanoparticles size, recent works on the anatase phase demonstrated the effect of the expressed surfaces nature on the nanoparticles photoreactivity. [2] Sol-gel method has been used to obtain a wide range of anatase nanoparticles sizes and morphologies by the control of concentrations, ions in solution, solution acidity and aging parameters. [3] In order to avoid the brookite phase often obtained with the anatase phase, microwave heating was efficiently used. Furthermore, conventional heating method has been compared with hydrothermal and microwave activated synthesis. The precise morphological control has been achieved by selective adsorption of organic molecules during synthesis: different shapes of anatase nanoparticles have been synthesized. [4,5]. The influences of synthesis parameters and the organic molecules nature on the nanoparticles structure and morphology have been analysed with various techniques, such as XRD and HRTEM. [less ▲]
