We are increasingly confronted with severe social and economic impacts of environmental degradation all over the world. From a valuation perspective, problems conflicts originate from trade-offs between values. The urgency importance to integrate nature's diverse values in decisions actions stand out more than ever. Valuation, its broad sense 'assigning importance', is inherently part most on natural resource land use. Scholars different traditions -while moving heuristic interdisciplinary...

Nature-based solutions (NBS) find increasing attention as actions to address societal challenges through harnessing ecological processes, yet knowledge gaps exist regarding approaches landscape planning with NBS. This paper aims provide suggestions of how NBS can be conceptualized and applied in practice. We develop a framework for by merging insights from literature case study the Lahn river landscape, Germany. Our relates three key criteria that define NBS, consists six steps planning:...

Growing demand of resources increases pressure on ecosystem services (ES) and biodiversity. Monetary valuation ES is frequently seen as a decision-support tool by providing explicit values for unconsidered, non-market goods services. Here we present global value transfer functions using meta-analytic framework the synthesis 194 case studies capturing 839 monetary ES. For 12 variance could be explained with subset 93 study- site-specific variables utilizing boosted regression trees. This...

Abstract The suitability of a commercial and industrially applied Cu‐based catalyst for the synthesis methanol by CO 2 hydrogenation was investigated. Unexpectedly, this system showed high stability well‐performance under conditions that may be relevant chemical energy conversion using hydrogen from renewable technologies. This demonstrated excellent dynamical process operation essential effective compensation volatility sources.

A user-friendly, portable, low-cost readout system for the on-site or point-of-care characterization of chemo- and biosensors based on an electrolyte–insulator–semiconductor capacitor (EISCAP) has been developed using a thumb-drive-sized commercial impedance analyzer. The is controlled by custom Python script allows to characterize EISCAP sensors with different methods (impedance spectra, capacitance-voltage, constant-capacitance modes), which are selected in user interface. performance...

Noble-metal-free perovskite oxides are promising and well-known catalysts for high-temperature gas-phase oxidation reactions, but their application in selective reactions the liquid phase has rarely been studied. We report liquid-phase of cinnamyl alcohol over spray-flame synthesized LaCo1-x Fex O3 nanoparticles with tert-butyl hydroperoxide (TBHP) as oxidizing agent under mild reaction conditions. The were characterized by XRD, BET, EDS elemental analysis. LaCo0.8 Fe0.2 showed best...

NaNbO3 enriched with oxygen vacancies by Ni doping was successfully synthesized via a polymerized complex method and applied as photocatalyst in the oxidation of cinnamyl alcohol (CA) to cinnamaldehyde air. Reaction rates high 45 μmol h–1 were achieved under visible light apparent quantum efficiency 67.2% excellent chemoselectivity larger than 99%. UV–vis, electron paramagnetic resonance, attenuated total reflectance infrared spectroscopy results indicate that CA molecules preferentially...

Abstract Highly selective one‐step hydrogenation of phenol to cyclohexanone, an important intermediate in the production nylon 6 and 66, is desirable but remains a challenge. Pd nanoparticles supported on nitrogen‐ oxygen‐functionalized carbon nanotubes (NCNTs, OCNTs) were prepared, characterized, applied cyclohexanone study effect N‐doping. Almost full conversion with high selectivity was achieved over Pd/NCNT under mild reaction conditions using either H 2 or formic acid (FA) as hydrogen...

Abstract Ecosystem service research has gained attraction, and the topic is also high on policy agenda. Projects such as TEEB have generalized results of individual case studies to provide guidelines for makers stakeholders. Seppelt et al. (2011) raised critical questions about four facets that characterize holistic ideal ecosystem services research: (i) biophysical realism data models; (ii) consideration trade-offs between services; (iii) recognition off-site effects; (iv) comprehensive but...

Abstract Cu‐Co‐based catalysts provide promising systems for higher alcohol synthesis (HAS) due to a synergistic dual‐site mechanism. Bimetallic Cu‐Co (alloy) nanoparticles are assumed be the active sites, but cobalt carbide (Co 2 C) forming under reaction conditions also seems influence formation of C 2+ OH. Na‐doped Co‐modified Cu/ZnO/Al O 3 is applied as benchmark catalyst within Carbon2Chem® subproject L4 providing suitable performance in terms CO conversion and OH selectivity. However,...
