Abstract Rapid urbanization and increasing climate risks pose serious challenges for cities in the Global South, where vulnerable populations often face exclusion from planning processes. Few studies have explicitly combined resilience components and urban planning approaches to resilience. This research aims to develop a conceptual framework for inclusive climate change–resilient urban planning by integrating resilience dimensions with equity and participation in urban governance. This is based on a qualitative analysis of available literature, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and is applied to the case of Dhaka, Bangladesh, a city marked by climate vulnerability and institutional complexity. The proposed framework identifies three core dimensions of resilience—physical, socioeconomic, and institutional—and links them to inclusive planning tools. Findings reveal that although inclusive principles are recognized in Dhaka’s planning policies, implementation is constrained by fragmented governance and limited community engagement. The framework offers practical guidance to urban planners and policymakers for advancing equitable and participatory climate resilience planning. It can be adapted to other cities across the Global South facing similar environmental, social, and governance challenges.
Pristine biochar (PBC) and phosphoric acid-activated biochar (PAC) derived from pomegranate peel powder were produced and evaluated for the adsorption of tetracycline (TC) from aqueous solution. Physicochemical characterization using BET, FESEM and FTIR complements the development of microporous network alongside mesoporous architecture in PAC and the presence of functional groups for TC interaction. PAC exhibited high specific surface area of 1882 m2/g compared to PBC with specific surface area of 195 m2/g. Batch adsorption experiments were performed at pH 4, initial TC solution concentration of 10–150 mg/L, adsorbent dosage of 5–15 mg, contact time of 300 min and temperature range between 298 and 318 K. The adsorption kinetics was found to follow pseudo second-order model, while the Langmuir model provided the best correlation with maximum adsorption capacities of 436 mg/g and 596 mg/g at 25 °C and 45 °C, respectively. Regeneration studies shows that PAC biohar mainitained TC removal efficiency > 89% over five cycles of adsorption-desorption test. The results demonstrate the efficacy of phosphoric acid-activated pomegranate peel carbon as a sustainable adsorbent for removing pharmaceutical contaminants from water.
Transition-metal (TM)-doped MXenes stand out as highly promising earth-abundant electrocatalysts for the hydrogen evolution reaction (HER), paving the way for cost-effective and sustainable green hydrogen generation. This review surveys the latest developments in TM-doped MXene systems for HER, emphasizing how diverse fabrication routes, including in situ incorporation during MAX-phase synthesis and post-etching modifications via atomic layer deposition (ALD), plasma-enhanced chemical vapor deposition (PECVD), and electrochemical deposition, shape their electronic properties and catalytic efficiency. Insights from d-band center theory, operando spectroscopic techniques, and deliberate active-site tuning are integrated to illustrate pathways toward optimal hydrogen binding energetics (ΔGH* ≈ 0 eV). Benchmark comparisons reveal that carefully engineered TM-doped MXenes frequently deliver overpotentials, Tafel slopes, mass activities, and other metrics that approach or outperform conventional noble-metal catalysts. The review also critically evaluates ongoing limitations, such as susceptibility to oxidation, dopant instability, and nanosheet restacking, while exploring architectural innovations and protective modifications as effective countermeasures. Looking ahead, the discussion highlights transformative opportunities in machine-learning-guided discovery, exploitation of quantum phenomena, and nature-inspired fabrication routes to bridge the gap toward practical, large-scale implementation.
During the acidizing process of petroleum oil wells aimed at increasing oil production, a 15% HCl solution is introduced into the oil well via N80 steel (NS) tubing. This study examines the effectiveness of two pyrrolederived compounds, N2,N4-bis(4-(4-methoxyphenyl)thiazol-2-yl)-3,5-dimethyl-1H-pyrrole-2,4-dicarboxamide (MPTP) and N2,N4-bis(4-(4-chlorophenyl)thiazol-2-yl)-3,5-dimethyl-1H-pyrrole-2,4-dicarboxamide (CPTP), in inhibiting corrosion on NS in a 15% HCl solution through methods such as weight loss, electrochemical analysis, surface examination, contact angle measurement and computational methods. The investigated pyrrole derivatives (MPTP and CPTP) were synthesized using green chemistry principles, minimizing the use of harmful solvents and reagents. Both inhibitors offer higher inhibition efficiency as compared to most of the similar type of inhibitors reported in literature. MPTP and CPTP offered maximum inhibition efficiencies of 98.1% and 96.4 %, respectively, at 303 K with a dosage of 250 ppm, while retaining significant performance at 333 K (83.02% and 74.3%, respectively). Both MPTP and CPTP demonstrated mixed inhibitory behavior, exhibiting both anodic and cathodic characteristics, and adsorbed onto NS through a mixed adsorption process that follows the Langmuir isotherm. The analyses conducted using FESEM, AFM, and XPS indicated the presence of a protective film formed by the inhibitors, which is responsible for the corrosion inhibition observed on the NS surface. Molecular modeling (DFT, Fukui and Monte Carlo simulation) studies supported the experimental results. Thus investigated inhibitors may find application in petroleum production industry.
