- In this study we designed and tested a methodology to minimize the variation of soil matric potential due to changes in soil water content, thus achieving a close control over the water regime in a microcosm, used to study the biocontrol of Pythium sp. infection of seeds by antagonistic bacteria. The variation of volumetric water content and matric potential were monitored at different depths during an average experimental period of 14 days in soil, contained in replicate 1 315 cm(3) microcosms, each sown with 16 sugar beet (Beta vulgaris) seeds and placed in a phytotron. Several experiments with target soil matric potentials of -10, -100 and -300 kPa were performed. It was found possible to maintain a matric potential of about -10 kPa in soil with minimum water content gradients between different parts of the microcosm by watering uniformly at each depth. With all appropriate watering and sampling procedure it was also possible to control psi(m) between -150 and -50 kPa, with a target value around -100 kPa; and to control psi(m) the range between -250 and -375 kPa for a target value of -300 kPa. In all experiments spatial and temporal variability of matric potential was larger at the top than in the Middle and in the bottom of microcosms. Variability in matric potential between replicate microcosms within each experiments was attributed to slight variation in packing, soil texture and drying rate, initial VWC.

Patent management: The prominent role of strategy and organization

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this article is twofold; to verify the existence of different profiles of firms based on the level of sophistication of their patent management core processes, and to test the impact of the interplay between two patent management supporting dimensions, namely patent strategy and organization for patenting, on the level of sophistication of patent management core processes. The method consists of a survey study, collecting data from a set of European patent management professionals. This data is analyzed with factor analysis, cluster analysis, and regression analysis to test a number of hypotheses. The results show that patent strategy positively and significantly impacts patent management sophistication, and that the patent organization positively moderates this relationship. In other words, a patent strategy, supported by a well-developed patent organization and culture, will positively influence the processes of managing a firm’s patent portfolio. This study is, to our knowledge, the first one to provide quantitative evidence that supports the notion that it is important to take a strategic and organizational perspective of patent management.

What is Patent Management? The Purification and Validation of an Integrated Measurement Scale

- Academics and practitioners have since decades been interested in the organizational and managerial aspects of patent management. However, little attention has been devoted to validating and testing a measurement scale of patent management. With this background, the current article aims to empirically assess the factor structure of a patent management measurement scale, purify the scale, and validate it. The methodology follows the widely recognized procedure for scale validation and focuses on two steps: scale purification through an exploratory factor analysis on survey data and scale finalization through a confirmatory factor analysis performed on another set of data. The article yields that patent management has five core processes, namely generation, freedom to operate, portfolio management, exploitation and enforcement, and intelligence, as well as two supporting dimensions, namely strategy and organization for patenting. For each of these core processes and supporting dimensions, we outline the formative subconstructs as well as how these subconstructs are reflected in observable and measurable items. With the validity analysis, we show the significant impact of patent management on radical innovation performance.

- The implementation of high potential materials as positive electrodes in high energy Li-ion batteries requires to develop scalable and smart synthetic routes. In the case of the LiNi0.5Mn1.5O4 (LNMO) spinel material, a successful preparation strategy must drive the phase formation in order to obtain structural, morphological and surface properties capable to boost performances in lithium cells and minimize the electrolyte degradation. Here we discuss a novel simple and easily scalable mechanochemical synthetic route, followed by a high temperature annealing in air, to prepare LMNO materials starting from oxides. A synergic doping with chromium and iron has been incorporated, resulting in the spontaneous segregation of a CrOx-rich surface layer. The effect of the annealing temperature on the physico-chemical properties of the LMNO material has been investigated as well as the effect on the performances in Licells.

- Lithium–sulfur (Li/S) batteries suffer from “shuttle” reactions in which soluble polysulfide species continuously migrate to and from the Li metal anode. As a consequence, the loss of active material and reactions at the surface of Li limit the practical applications of Li/S batteries. LiNO3 has been proposed as an electrolyte additive to reduce the shuttle reactions by aiding the formation of a stable solid electrolyte interphase (SEI) at the Li metal, limiting polysulfide shuttling. However, LiNO3 is continuously consumed during cycling, especially at low current rates. Therefore, the Li/S battery cycle life is limited by the LiNO3 concentration in the electrolyte. In this work, an ionic liquid (IL) [N-methyl-(n-butyl)pyrrolidinium bis(trifluoromethylsulfonyl)imide] was used as an additive to enable longer cycle life of Li/S batteries. By tuning the IL concentration, an enhanced stability of the SEI and lower flammability of the solutions were demonstrated, that is, higher safety of the battery. The Li/S cell built with a high sulfur mass loading (4 mg cm−2) and containing the IL-based electrolyte demonstrated a stable capacity of 600 mAh g−1 for more than double the number of cycles of a cell containing LiNO3 additive.

- The understanding of extreme geomagnetic storms is one of the key issues in space weather. Such phenomena have been receiving increasing attention, especially with the aim of forecasting strong geomagnetic storms generated by high-energy solar events since they can severely perturb the near-Earth space environment. Here, the disturbance storm time index Dst, a crucial geomagnetic activity proxy for Sun-Earth interactions, is analyzed as a function of the energy carried by different solar wind streams. To determine the solar cycle activity influence on Dst, a 12-year dataset was split into sub-periods of maximum and minimum solar activity. Solar wind energy and geomagnetic activity were closely correlated for both periods of activity. Slow wind streams had negligible effects on Earth regardless of their energy, while high-speed streams may induce severe geomagnetic storming depending on the energy (kinetic or magnetic) carried by the flow. The difference between the two periods may be related to the higher rate of geo-effective events during the maximum activity, where coronal mass ejections represent the most energetic and geo-effective driver. During the minimum period, despite a lower rate of high energetic events, a moderate disturbance in the Dst index can be induced.

"pop-On and Pop-Off" Surface Chemistry of Alanine on Ni{111} under Elevated Hydrogen Pressures

- The coadsorption of hydrogen with a simple chiral modifier, alanine, on Ni{111} was studied using density functional theory in combination with ambient-pressure X-ray photoelectron spectroscopy and X-ray absorption spectroscopy at temperatures of 300 K and above, which are representative of chiral hydrogenation reactions. Depending on the hydrogen pressure, the surface enables protons to "pop-on and -off" the modifier molecules, thus significantly altering the adsorption geometry and chemical nature of alanine from anionic tridentate in ultrahigh vacuum to predominantly zwitterionic bidentate at hydrogen pressures above 0.1 Torr. This hydrogen-stabilized modifier geometry allows alternative mechanisms for proton transfer and the creation of enatioselective reaction environments.
