, 2014 The aim of this thesis was to verify the feasibility of the hydrogen production process with purple non sulfur bacteria both under sunlight irradiation in an up-scaled system and with the use of low cost substrates. Among the products offermentations tested the best results were obtained with a medium derived from vegetable wastes.

A decomposition theorem for immersions of product manifolds [PDF]
arXiv, 2013 We introduce polar metrics on a product manifold, which have product and warped product metrics as special cases. We prove a de Rham-type theorem characterizing Riemannian manifolds that can be locally decomposed as a product manifold endowed with a polar metric.

Aerosol Jet Printing of Superhydrophobic Surfaces
Advanced Materials Technologies, EarlyView.A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Products of abstract polytopes [PDF]
arXiv, 2016 Given two convex polytopes, the join, the cartesian product and the direct sum of them are well understood. In this paper we extend these three kinds of products to abstract polytopes and introduce a new product, called the topological product, which also arises in a natural way. We show that these products have unique prime factorization theorems.

High‐Performance and Ultrafast Single Germanium Nanowire Photodetectors
Advanced Optical Materials, EarlyView.Semiconductor nanowire‐based photodetectors with high sensitivity and fast photoresponse in the near‐infrared wavelength range are crucial for applications in light‐wave communication switches, as well as environmental and atmospheric sensing. Here, the fabrication of an axial p‐n junction along single germanium nanowires and their photoresponse ...

Wreath products of cocommutative Hopf algebras [PDF]
arXiv, 2014 We define wreath products of cocommutative Hopf algebras, and show that they enjoy a universal property of classifying cleft extensions, analogous to the Kaloujnine-Krasner theorem for groups. We show that the group ring of a wreath product of groups is the wreath product of their group rings, and that (with a natural definition of wreath products of

Advanced Synthesis &Catalysis, EarlyView.Abstract Chiral, vicinal diols are of high interest for academic research and industrial applications. For synthesizing chiral diols, enzymes are important catalysts due to their high selectivity and ability to work under tolerable temperature and no pressure.
