Zr2PTe2 decomposes under release of Te2(g) + P4(g) forming the homogeneity range Zr2+δPTe2. The growth of single crystals of Zr2+δPTe2 succeeded by chemical vapour transport using iodine as transport agent from 830 °C in direction of higher temperatures up to 900 °C. Zr2+δPTe2 crystallizes in the rhombohedral space group R-3m (no. 166) with lattice parameters a = 383(1)…386(1) pm and c = 2935(4)…2970(4) pm for δ = 0…1, respectively. Single crystal data have been determined for Zr2.40(2)PTe2 with lattice parameters a = 385.24(4) pm and c = 2967.8(4) pm. The electronic structure and chemical bonding in Zr2+δPTe2 was investigated by the linear muffin–tin orbital (LMTO) method. Both Zr2PTe2 and Zr3PTe2 show non-vanishing DOS values at the Fermi level (EF) indicating metallic character. According to COHP bonding analyses, mainly the heteroatomic Zr–P and Zr–Te bonds are responsible for the structural stability of Zr3PTe2. The new Zr2–Te bond, which is not present in Zr2PTe2, is stronger than Zr1–Te and is thought to be responsible for the stability of phases having Zr in excess.

Therein, the relative energetical stability (En) of target compounds and possible decomposition are determined from quantum chemical DFT calculations. Phase formation and transition (Pha) is probed by a gas balance method, developed as high temperature gas balance concept. It helped to study the synthesis and stability range of several compounds experimentally. Applications of the concept and synthesis principles (Syn) of non-equilibrium phases are presented for allotropes of P, As, P1-xAsx, as well as binary and ternary compounds including the Zintl and Laves like phases IrPTe, NiP2, CoSbS, NiBiSe, Li0.2CdP2, Cu3CdCuP10, and Cd4Cu7As.

The previously known bismuth telluride iodides, BiTeI and Bi₂TeI, offer physical properties relevant for spintronics. Herewith a new cousin, Bi₃TeI (sp.gr. R3m, a = 440.12(2) pm, c = 3223.1(2) pm), joins the ranks and expands this structural family. Bi₃TeI = [Bi₂][BiTeI] represents a stack with strictly alternating building blocks. Conditions for reproducible synthesis and crystal-growth of Bi₂TeI and Bi₃TeI are ascertained, thus yielding platelet-like crystals on the millimeter size scale and enabling direct measurements. The crystal structures of Bi₂TeI and Bi₃TeI are examined by X-ray diffraction and electron microscopy. DFT calculations predict metallic properties of Bi₃TeI and an unconventional surface state residing on various surface terminations. This state emerges as a result of complex hybridization of atomic states due to their strong intermixing. Our study does not support the existence of new stacking variants BiₓTeI with x > 3; instead, it indicates a possible homogeneity range of Bi₃TeI. The series BiTeI–Bi₂TeI–Bi₃TeI illustrates the influence of structural modifications on topological properties.

With its regional location as hub in Southeast Asia, its airport, harbour and the intersection of main roads, the metropolis is well connected within the domestic as well as the most important international markets. Located downstream of the Saigon-Dong Nai River with a relatively flat terrain, the city traditionally has a strong relationship to water. It is located at the north-eastern fringe of the Mekong Delta and its southern part is connected to the east sea. Major parts of the city are situated on low-lying marshy lands that are crossed by a complex network of canals and rivers. These topographic and geographic conditions make the city extremely sensitive to various flood sources.

Rapidly developing Asian megacities, like Ho Chi Minh City (HCMC) in Vietnam, need to become more resilient and less vulnerable to climate change. Our contribution takes spatial planning as the starting point. It highlights opportunities and challenges for spatially-explicit adaptation strategies in HCMC and shows how adaptation to climate change can be used to influence land-use planning and future urban development. Special attention is given to urban water management issues. Here the focus lies on risk management and non-structural protection measures to lessen climate-related urban risks. For rapidly developing mega-urban regions the need for focused support and guidance in formulating and embedding suitable adaptation policies and spatially explicit zoning regulations is apparent. Within its multi-stakeholder environment borne out of conflicting interests, land use planning requires more than ever science-based information to formulate spatially explicit and integrated urban climate adaptation policies.

An important prerequisite for establishing much needed efficient and proactive, as well as rapid, adaptation planning strategies is the spatial and rational characterisation of the current urban fabric according to vulnerability relevant features. In our work an understanding of urban settlement patterns and urban structures allowed for the capturing of the highly dynamic spatiotemporal social and structural changes associated with rapid urbanisation processes. The aim was an integrated assessment of the underlying the inherent urban resilience based on coherent and credible indicator sets. The approach provides a common spatial framework at the resolution of the urban block for data integration various thematic and scientific disciplines at the same spatial scale. The scale provides a clear instrument to generate portfolios of block-specific core indicators, move across scales, run scenarios and aggregate to larger planning horizons, ultimately useful to determine hotspots for administrative interventions and to assist prioritising in spatial planning decision-making.
