Pseudotetrahedral Organotin-Capped Chalcogenidometalate Supermolecules with Optical Limiting Performance.

The rational design of crystalline clusters with adjustable compositions and dimensions is highly sought after but quite challenging as it is important to understand their structural evolution processes and to systematically establish structure-property relationships. Herein, a family of organotin-based sulfidometalate supertetrahedral clusters has been prepared via mixed metal and organotin strategies at low temperatures (60-120 °C). By engineering the metal composition, we can effectively control the size of the clusters, which ranges from 8 to 35, accompanied by variable configurations: P1-[(RSn)MS], T3-[(RSn)InMS] (R = butyl-Bu and phenyl-Ph; M = Cd, Zn, and Mn), T4-[(BuSn)InCuS], truncated P2, viz.

Four isomorphic P2 chalcogenide clusters named [SnInCuS]·11(HDBU) (1) (DBU = 1,8-diazabicyclo[5.4.0] undec-7-ene), [SnInCuSe]·6(HDMAPA)·2(DMAPA)·9EG (2) (DMAPA = 3-dimethylaminopropylamine, EG = ethylene glycol), [SnInCuSO]·6[HPMDETA]·10EG (3) (PMDETA = pentamethyldiethylenetriamine), [SnGaCuSO]·6(HDMAPA)·7EG (4) have been isolated organotin precursor and mixed-metal strategy.

Improvement Path for Resource-Constrained Cities Identified Using an Environmental Co-Governance Assessment Framework Based on BWM-mV Model.

Global warming and extreme weather have increased most people's awareness of the problem of environmental destruction. In the domain of sustainable development, environmental governance has received considerable scholarly attention. However, protecting and improving the environment requires not only substantial capital investment but also cooperation among stakeholders.

Understanding the Efficiency and Selectivity of Two-Electron Production of Metalloporphyrin-Embedded Zirconium-Pyrogallol Scaffolds in Electrochemical CO Reduction.

Because of the high efficiency and mild reaction conditions, electrocatalytic CO reduction (ECR) has attracted significant attention in recent years. However, the specific mechanism of the formation of the two-electron production (CO or HCOOH) in this reaction is still unclear. Herein, with density functional theory calculation and experimental manipulation, the specific mechanism of the selective two-electron reduction of CO has been systematically investigated, employing the polyphenolate-substituted metalloporphyrinic frameworks, ZrPP-1-M (M = Fe, Co, Ni, Cu, and Zn), as model catalysts.

Photochemical In Situ Exfoliation of Metal-Organic Frameworks for Enhanced Visible-Light-Driven CO Reduction.

Two novel two-dimensional metal-organic frameworks (2D MOFs), 2D-M TCPE (M=Co or Ni, TCPE=1,1,2,2-tetra(4-carboxylphenyl)ethylene), which are composed of staggered (4,4)-grid layers based on paddlewheel-shaped dimers, serve as heterogeneous photocatalysts for efficient reduction of CO to CO. During the visible-light-driven catalysis, these structures undergo in situ exfoliation to form nanosheets, which exhibit excellent stability and improved catalytic activity. The exfoliated 2D-M TCPE nanosheets display a high CO evolution rate of 4174 μmol g  h and high selectivity of 97.

Tin-oxychalcogenide supertetrahedral clusters maintained in a MTN zeolite-analog arrangement by coulombic interactions.

Two crystalline salts, T3-SnOX-MTN (X = S/Se, MTN denotes a defined zeotype), both spatially assembled in an MTN net, have been fabricated. This was achieved by interlinking the isolated tin-oxychalcogenide tetrahedrally shaped clusters of T3-[Sn10O8X16]8- (X = S/Se) through coulombic interactions with protonated organic amine templates. T3-SnOX-MTN (X = S/Se), with 74.

Developing a Sustainable Long-Term Ageing Health Care System Using the DANP-mV Model: Empirical Case of Taiwan.

Most of the baby boomers born after the Second World War (WWII) have passed the age of 65, meaning they have gradually lost their social functions and positions, and are facing the need for care. In Taiwan, the lack of a long-term care mechanism is having a certain degree of impact on society as a whole, and thus, it is important to have a mechanism to take care of the elderly. In order to make this system sustainable, sufficient funds and continuous improvement are important factors.

Dual-cubic-cage based lanthanide sulfate-carboxylpyrazolate frameworks with high hydrolytic stability and remarkable proton conduction.

Use of a Modified DANP-mV Model to Improve Quality of Life in Rural Residents: The Empirical Case of Xingshisi Village, China.

Climate change-related anomalies have increased public concern regarding environmental protection. This has opened newer rural development avenues. In this regard, livability of villages is crucial; it can be evaluated based on the villagers' quality of life (QoL).

Using the D-DANP-mV Model to Explore the Continuous System Improvement Strategy for Sustainable Development of Creative Communities.

With globalization, the notion of "creative city" has become a core concept of many cities in the world development policies, with real properties being upgraded or used to change, renewal is being conducted, and creative industries are emerging. This trend has reached its peak in the past decade, with different forms and scales gathering global development momentum among the creative communities to promote the development of creative economies. In recent years, however, there was still skepticism about the sustainability of the current creative communities.
