[Introduction:] Urban fragmentation resulting from Tunja’s Bicentennial Project (Colombia) raises socio-environmental and psychological effects that Latin-American scholarship has only partially addressed. [Objective:] To analyse how this fragmentation affects residents’ psychological health and urban sustainability, while providing a framework that other intermediate Latin-American cities can replicate. [Methodology:] A mixed-methods design was used: 120 stratified surveys and 12 semi-structured interviews with residents and shopkeepers; GIS mapping in QGIS to detect physical barriers and changes in accessibility; and quantitative–qualitative triangulation to validate findings (α = 0.84). [Results:] Seventy-five per cent of participants report negative impacts on daily activities. Geospatial indicators show a 32 % drop in inter-neighborhood connectivity and a 4 m² per-capita shortfall in public-space provision. These conditions correlate with a 28 % rise in perceived insecurity and 62 % overall urban dissatisfaction. [Discussion:] Comparing these findings with spatial-justice theory and case studies from Santiago, Mexico City and Recife reveals that interventions lacking an ecosystemic lens deepen socio-spatial inequality in intermediate Latin-American cities. [Conclusions:] As implemented, the works reinforce fragmentation and generate adverse psychological externalities. Three action lines are proposed: (1) green corridors to restore ecological connectivity and serve as a model for community-based coastal restoration elsewhere in the region; (2) mandatory psycho-environmental indicators in building permits; and (3) participatory governance to redirect future urban projects. These contributions offer a transferable framework for cities facing uncontrolled expansion and environmental degradation.

Degradation of cellulose-based wet wipes marketed as 'biodegradable' in their receiving urban rivers.

Polyhydroxyalkanoates (PHAs) hold significant potential as sustainable alternatives to fossil-based plastics because of their bio-based origin and inherent biodegradability. Poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) is a well-known commercial member of the PHA family characterized by good mechanical resistance and thermal behavior similar to that of some conventional polymers, such as polypropylene. However, its high crystallinity and fragility limit its application. Poly3-hydroxybutyrate-co-4-hydroxybutyrate (P(3HB-co-4HB)) is a new commercial copolymer containing a 4-hydroxybutyrate (4HB) segment that provides increased flexibility because of its amorphous phase. In this study, PHBV and P(3HB-co-4HB) were blended by extrusion, varying the percentage of P(3HB-co-4HB) to improve the PHBV properties without losing the PHA assets and potentializing the insertion of this biopolymer in the market. The results indicate that the impact energy required for fracture was increased in the polymer blends. These blends exhibited greater thermal stability than pure PHBV, with no significant changes observed in the melting and crystallization temperatures. Furthermore, blending was found to reduce shrinkage in injection-molded samples. The degradation in the soil increased with the highest P(3HB-co-4HB) content. Through 3D printing, it was observed that the blends led to an increase in the melt flow index and a reduction in warpage in the printed objects, thereby facilitating the processing of these materials. Consequently, incorporating P(3HB-co-4HB) into PHBV has emerged as a promising strategy to address the inherent limitations of PHBV. This approach not only enhances the mechanical properties and thermal stability but also improves the overall processability, thereby expanding the potential applications of this biopolymer blend.

The impact of skewed income distribution on environmental degradation: a nonlinear analysis of India

High-nickel cobalt-free cathode materials are regarded as some of the promising candidates for high-energy-density lithium-ion batteries due to their excellent attributes of high capacity and cost-effectiveness. However, increasing the nickel content and removing cobalt lead to degradation of the electrode-electrolyte interfacial environment and other bulk-phase layered structure issues, which significantly compromise the battery's cycle life. In this work, a W-doped LiNi0.90Mn0.07Al0.03O2 cathode material was synthesized by introducing a small amount (2 mol%) of tungsten (W) during the lithiation procedure. The W-doping enhanced the cyclic stability of the LiNi0.90Mn0.07Al0.03O2 cathode (capacity retention after 100 cycles: 90.82% vs. 88.99% for the pristine material at 4.3 V) remarkably. These improvements are attributed to the high-valence W6+ passivating the cathode material surface activity, thereby stabilizing the bulk structure and electrode-electrolyte interface. These findings provide valuable strategic insights for developing high-nickel, cobalt-free cathode materials in lithium-ion batteries.

Sustainability is getting preference now-a-days in most of the countries in the world. This implies industrial and other developments for economic growth, and of course civilization, but certainly not at the cost of environmental degradation. Environmental conservation is a must. One of the major components of industrial sectors is their electrical energy inputs through electrical substation. Numerous research addresses the issue of energy pollution, cantering on fossil fuel. A very few research can be found which address the issue of pollution generated from electrical energy. This research addresses this issue, with special attention to electrical substations. In the last two or three decades, several electrical equipment manufacturers have started producing this equipment in Bangladesh, which were previously import-oriented. This equipment use various types of oils, acids, zinc and other metals, which are all environmentally hazardous. Thus, any industrial company, buying such equipment from substation manufacturers, should consider green aspects. As such, now it is of prime importance to select green suppliers of substation equipment. Since selection of right or green supplier involves multi-criteria evaluation, Multi-criteria Decision Making (MCDM) technique is essential. Additionally, both qualitative and quantitative criteria require fuzzy analysis to make it more precise and realistic. This research addressed the issue of environmental pollution, its sources, nature and severity, and their mitigation through selecting green suppliers.

The global community currently faces significant challenges in meeting the rising demand for energy production. The development of clean energy technologies has gained substantial attention due to increasing energy shortages and worsening environmental degradation. Addressing these challenges requires the development of new materials. This study investigates the structural, electronic, and optical properties of Ti3XC2 (X = Ge, Pb, or Bi) MXenes, focusing on deintercalation and intercalation stages. The structural analysis demonstrates that the insertion and removal of Ge, Pb, and Bi within Ti3XC2 MXene significantly affect cell volume, with the second deintercalation stage exhibiting greater structural stability compared to the first. These MXenes exhibit metallic conductivity confirmed by density of states (DOS) calculations which reveal a zero band gap even with GGA corrections. The optical properties, including reflectivity, dielectric function and energy loss highlight distinct behavior among the intercalated structures, particularly for Ti3GeC2 which shows higher energy loss peaks in the 14-16 eV range. These findings provide valuable insights into the electronics and structural behavior of Ti3XC2 MXenes, making them promising candidates for advanced energy storage and electronic applications.
