- The FP7 Research for SME project IMAGINE - a low cost, high performance monolithic passive mm-wave imager front-end is described in this paper. The main innovation areas for the project are: i) the development of a 94 GHz radiometer chipset and matching circuits suitable for monolithic integration. The chipset consists of a W-band low noise amplifier, fabricated using the commercially available OMMIC D007IH GaAs mHEMT process, and a zero bias resonant interband tunneling diode, fabricated using a patented epi-layer structure that is lattice matched to the same D007IH process; ii) the development of a 94 GHz antenna adapted for low cost manufacturing methods with performance suitable for real-time imaging; iii) the development of a low cost liquid crystal polymer PCB build-up technology with performance suitable for the integration and assembly of a 94 GHz radiometer module; iv) the assembly of technology demonstrator modules. The results achieved in these areas are presented.

- Enzymes active on glycosidic bonds are defined according to the stereochemistry of both substrates and products of the reactions they catalyze. The CAZy classification further assigns these enzymes into sequence-based families sharing a common stereochemistry for substrates (either α- or β-) and products (i.e., inverting or retaining mechanism). Here we describe the N-acetylgalactosaminidases AmGH109A and AmGH109B (i.e., GH109: glycoside hydrolase family 109) from the human gut symbiont Akkermansia muciniphila. Notably, AmGH109A displays α-retaining and β-inverting N-acetylgalactosaminidase activities with comparable efficiencies on natural disaccharides. This dual specificity could provide an advantage in targeting a broader range of host-derived glycans. We rationalize this discovery through bioinformatics, structural, mutational, and computational studies, unveiling a histidine residing in a conserved GGHGG motif as the elusive catalytic acid-base of the GH109 family.

Tidskriftsartikel (refereegranskat)abstract
- Considerable progress has been made over the last decades in thermal spray technologies, practices and applications. However, like other technologies, they have to continuously evolve to meet new problems and market requirements. This article aims to identify the current challenges limiting the evolution of these technologies and to propose research directions and priorities to meet these challenges. It was prepared on the basis of a collection of short articles written by experts in thermal spray who were asked to present a snapshot of the current state of their specific field, give their views on current challenges faced by the field and provide some guidance as to the R&D required to meet these challenges. The article is divided in three sections that deal with the emerging thermal spray processes, coating properties and function, and biomedical, electronic, aerospace and energy generation applications. © 2016, ASM International.
