Disodium calcium dinickel(II) bis[diphosphate(V)] decahydrate

open access: yesActa Crystallographica Section E, 2011
In the title compound, Na2CaNi2(P2O7)2(H2O)10, there are two distinct P-atom sites, each tetrahedrally coordinated by four O atoms. The resulting phosphate tetrahedra link through a common O atom, forming a [P2O7]4− diphosphate unit. The Ni&

After the Hype: Resilience Seeking in Emerging Technology Ecosystems

open access: yesJournal of Product Innovation Management, Volume 43, Issue 5, Page 793-826, September 2026.
ABSTRACT Academic Summary Hype often helps emerging technology ecosystems gain early support for their innovative value propositions, but the initial excitement around the technology typically vanishes at some point. This decrease in excitement and support may lead some ecosystems to fail while others are resilient and recover.

Onset of collectivity in neutron deficient Po196,198 [PDF]

open access: yes, 1995
We have studied via in-beam -ray spectroscopy Po196 and Po198, which are the first neutron-deficient Po isotopes to exhibit a collective low-lying structure.

High resolution measurement of the 208Pb(p,γ) capture reaction up to Eγ=19 MeV [PDF]

open access: yes, 2004
High-energy γ rays produced by the 208Pb(p,γ) reaction were measured with the AFRODITE germanium detector array. The use of Ge instead of NaI detectors improved the energy resolution by more than a factor of 10 in the γ-ray energy range between 10 and 19

Silver europium(III) polyphosphate

open access: yesActa Crystallographica Section E, 2009
Europium(III) silver polyphosphate, AgEu(PO3)4, was prepared by the flux method. The atomic arrangement is built up by infinite (PO3)n chains (periodicity of 4) extending along the c axis. These chains are joined to each other by EuO8 dodecahedra. The Ag+

Synthesis and Insecticidal Activity of Mesoionic Pyrido[1,2-α]pyrimidinone Derivatives Containing a Neonicotinoid Moiety

open access: yes, 2018
Mesoionic pyrido[1,2-α]pyrimidinone derivatives containing a neonicotinoid moiety were designed, synthesized, and evaluated for their insecticidal activity.

SAS Macros for Analysis of Unreplicated 2^k and 2^(k-p) Designs with a Possible Outlier

open access: yesJournal of Statistical Software, 2008
Many techniques have been proposed for judging the significance of effects in unreplicated 2^k and 2^(k-p) designs. However, relatively few methods have been proposed for analyzing unreplicated designs with possible outliers.

g factors of the 9- and 12+ isomeric states in 200Pb

open access: yes, 1975
The g factors of the 9- state (2.236 MeV, t=694 nsec) and the 12+ state (~3.1 MeV, t=228 nsec) in 200Pb have been measured as g(9-)=-0.030(3) and g(12+)=-0.157(6) by a time-differential perturbed-angular-distribution technique.
