- Design discipline has been relatively slow to recognize the existence and impacts of postmodernism as compared to sociology, political science, marketing and management disciplines, however, recently postmodernist implications have begun to be explored by design scholars. Yet our review of the literature led us to conclude that the relationship between postmodernism and design thinking has received little, if any attention from design management scholars. The objective of this paper, then, is to expand the discussion on the relationship between postmodern organization and design thinking, to suggest strategic implications for design managers and research opportunities for management scholars. Keywords: design, design thinking, management, postmodernism, postmodernity

- The elements hydrogen, carbon, and nitrogen are among the most abundant in the solar system. Still, little is known about the ternary compounds these elements can form under the high-pressure and high-temperature conditions found in the outer planets' interiors. These materials are also of significant research interest since they are predicted to feature many desirable properties such as high thermal conductivity and hardness due to strong covalent bonding networks. In this study, the high-pressure high-temperature reaction behavior of malononitrile H2C(CN)(2), dicyandiamide (H2N)(2)C=NCN, and melamine (C3N3)(NH2)(3) was investigated in laser-heated diamond anvil cells. Two previously unknown compounds, namely alpha-C(NH)(2) and beta-C(NH)(2), have been synthesized and found to have fully sp(3)-hybridized carbon atoms. alpha-C(NH)(2) crystallizes in a distorted beta-cristobalite structure, while beta-C(NH)(2) is built from previously unknown imide-bridged 2,4,6,8,9,10-hexaazaadamantane units, which form two independent interpenetrating diamond-like networks. Their stability domains and compressibility were studied, for which supporting density functional theory calculations were performed.

- Transition metal nitrides, particularly those of 5d metals, are known for their outstanding properties, often relevant for industrial applications. Among these metal elements, tungsten is especially attractive given its low cost. In this high-pressure investigation of the W-N system, two novel ultra-incompressible tungsten nitride superconductors, namely W2N3 and W3N5, are successfully synthesized at 35 and 56 GPa, respectively, through a direct reaction between N2 and W in laser-heated diamond anvil cells. Their crystal structure is determined using synchrotron single-crystal X-ray diffraction. While the W2N3 solid's sole constituting nitrogen species are N3- units, W3N5 features both discrete N3- as well as N24- pernitride anions. The bulk modulus of W2N3 and W3N5 is experimentally determined to be 380(3) and 406(7) GPa, and their ultra-incompressible behavior is rationalized by their constituting WN7 polyhedra and their linkages. Importantly, both W2N3 and W3N5 are recoverable to ambient conditions and stable in air. Density functional theory calculations reveal W2N3 and W3N5 to have a Vickers hardness of 30 and 34 GPa, and superconducting transition temperatures at ambient pressure (50 GPa) of 11.6 K (9.8 K) and 9.4 K (7.2 K), respectively. Additionally, transport measurements performed at 50 GPa on W2N3 corroborate with the calculations. Two recoverable tungsten nitrides, namely W2N3 and W3N5, are synthesized using laser-heated diamond anvil cells. Both compounds exhibit a high bulk modulus, hardness, and superconducting transition temperature. image
