Various experimental approaches of transformative research in real-world settings have emerged. Yet, similarities, differences, and specific contributions remain unclear. A characteristic-based comparison reveals complementarities provides orientation.Real-world laboratories (RwLs, German Reallabore ) belong to a family increasingly popular transdisciplinary at the science-society interface. As these general, RwLs particular, often lack clear definitions key characteristics their...
The transformative research approach of Real-World Laboratories (RWL) has recently attracted attention in German sustainability science. Some definitions and understandings have been published, but guidelines procedural quality criteria for establishing running a RWL are still missing. To address this gap, article two aims. First, it aims to derive key components RWLs from the current discourse on similar, more elaborated approaches. Second, transfer these into comprehensive practice. This...
In order to grasp the transformative potential of real-world laboratories, it is essential understand them as a large-scale research infrastructure. Unlike single transdisciplinary projects and processes, labs are not only about temporary interventions or knowledge integration. They also establishing long-lasting spaces for transformation reflexive learning.
Valence tautomerism involving coupled Cu+/2+ and quinone−\./2− redox systems has been observed for the first time outside an enzymatic situation (amine oxidases) with chelates L as CuI CuII affine coligands. Even slight variations of quinone substitution pattern suffice to shift valence tautomer equilibrium completely. [(L)CuII(Q−II)] ⇌ [(L)CuI(Q−I)]
The interface of phase-separated $^{3}\mathrm{He}$-$^{4}\mathrm{He}$ mixtures, when charged with negative ions, shows a pronounced softening its ripplon spectrum at wave vectors around the inverse capillary length. As electrical field perpendicular to is increased beyond value ${E}_{c}$ where frequency soft vanishes, phase transition spontaneous deformation in form an ordered array dimples observed.
Coating systems used for anticorrosion protection usually consist of a primer, intermediate layers, and topcoats. Zinc-rich primers, which serve as cathodic barrier protection, are widely the corrosion steel structures. Due to fact that functioning above-mentioned coatings is related conduction galvanic current, these types highly pigmented with zinc (up 80 wt% in dry coating). This may result not only deterioration performance coating system but also have negative impact on environment....
The g factor components of [(NC)5M(NO)]3- were calculated by relativistic density functional calculations, including spin−orbit coupling. values are in good agreement with previous (M = Fe) and new experimental results Ru, Os). Spin−orbit coupling effects particularly strong for the osmium system. Whereas MII−NO• is most appropriate formulation describing spin distribution, there substantial contribution (ca. 25%) from metal to singly occupied MO each case.
No need for a solid template: Hollow gold spheres (see TEM image) have been realized through microemulsion approach. The wall thickness of 2–6 nm and an inner diameter 20–40 nm.
Abstract The redox properties of organometallic nickel complexes the type [(α‐diimine)Ni(Mes)Br], [(α‐diimine)Ni(Mes) 2 ] and trans ‐[(PPh 3 ) Ni(Mes)Br] Ni(Fmes)Br] [Mes = mesityl (2,4,6‐trimethylphenyl); Fmes tris(2,4,6‐trifluoromethyl)phenyl] have been studied in detail by various electrochemical spectroelectrochemical (UV/Vis/NIR EPR) methods. Upon reduction, bromido derivatives undergo cleavage bromide ligand. resulting reactive species their products from follow‐up reactions are...
In real-world laboratories (RwLs), researchers do more than conventional research. They slip into different roles. Why they “change faces”? Based on comparisons of three urban RwLs, we analyse the process steps and conditions influencing choices made by to adopt certain roles.Real-world (RwLs) often put in highly demanding research contexts regarding their roles self-conceptions. Helpful have been described but still little is known about factors adoption Using data from parallel RwLs...
The dinuclear radical anion complexes [(mu-L)[Re(CO)(3)Cl](2)](*)(-), L = 2,2'-azobispyridine (abpy) and 2,2'-azobis(5-chloropyrimidine) (abcp), were investigated by EPR at 9.5, 94, 230, 285 GHz (abpy complex) 9.5 (abcp complex). Whereas the X-band measurements yielded only isotropic metal hyperfine coupling of (185,187)Re isotopes, high-frequency experiments in glassy frozen CH(2)Cl(2)/toluene solution revealed g components. Both a((185,187)Re) value anisotropy, g(1) - g(3), are larger for...
The mobilities of positive and negative ions have been measured in the normal phase a $^{3}\mathrm{He}$-$^{4}\mathrm{He}$ mixture near tricritical point. Whereas for nearly same weak temperature dependence observed as pure $^{3}\mathrm{He}$, mobility drops sharply by almost factor 2 when separation is approached. This attributed to condensation $^{4}\mathrm{He}$ onto positive-ion surface.

To address the evaluation of societal impact real-world labs, we present a framework developed for analysis structure-agency dynamics: structuration theory. Using this tool on neighbourhood level, assess outcomes six projects co-productive city-making.Ways evaluating labs as transdisciplinary and transformative research format are under discussion. We an approach rooted in theory, with focus dynamics at science-society interface. applied theory its four modalities (interpretation schemes,...
Real-world labs are witnessing continued growth and institutionalization in the field of transformation-oriented sustainability research, as well adjacent disciplines. With their experimental research agendas, these aim at transformations, however, there is still a need to improve understanding impacts. Drawing from this Special Issue’s contributions, we offer broad overview impacts achieved by various real-world labs, highlight diverse areas forms impact, elucidate strategies mechanisms for...
