Carbon Nanotubes Enhanced TiO2/g-C3N4 as a Potential Nanocomposite Material for Impedance-Type Humidity Sensors
No full textHybrid Mesoporous Mn2O3/Carbon as Electrode Materials for Supercapacitors
No full textA new α-Mn2O3/carbon (Mn2O3/C) nanocomposite was synthesised via ultrasonication-assisted co-precipitation, calcination, and freeze-drying. The method involved forming a stable Mn–citrate precursor, which, upon calcination, yielded crystalline α-Mn2O3 embedded in a carbonaceous matrix. Structural investigations using FT-IR, XRD, and FE-SEM validated the development of a porous nanosheet morphology, with well-dispersed Mn2O3 nanocrystals closely integrated within a carbon matrix. The hierarchical porosity and graphitic domains improved ionic accessibility and charge transfer at the oxide-carbon interface. Electrochemical investigations revealed significant pseudocapacitive characteristics accompanied by Mn redox shifts. The Mn2O3/C electrode achieved a specific capacitance of 1700 F g− 1 at 0.5 A g− 1 in a 6 M KOH electrolyte. It maintains 94% of its efficiency after 5000 cycles, indicating high recyclability. The synergistic integration of Mn2O3 and Carbon in Mn2O3/C, along with its structural integrity and effective ion/electron transport, renders the material promising for supercapacitors
The Impact of Sustaining The Agility of Attitude Transformation on Credibility Matrix: The Mediation Effect of Social Media Advertisements Insights From The Touristic Hospitality Context In Egypt
No full textThis paper examines the effects of sustaining the agility of attitude transformation on credibility matrix with respect to the mediation effect of social media advertisements. Under the Umbrella of New Public management, the Agility of attitude transformation entails the vision of a new policy approach as it is facing a volatile environment of risks and challenges. The group of factors in this study includes the agility of attitude transformation as an independent variable measured by (process- attitudes, process-competence, and process-resource), while the credibility matrix is determined by (customers’ trust and customer experience) as dependent factors. It’s important to note that there is no sufficient data regarding the effect of sustaining the agility of attitude transformation on credibility matrix inside the tourism/hospitality context in Egypt. Therefore, the utility of this research can contribute to a deeper understanding of the paper variables. The current research is based on quantitative data derived from an online survey which will be distributed among hotel visitors in Egypt. On the academic side, the research allows underlining significant issues and formulating vital findings in relevance to cover the gaps in data scarcity about the agility policy of attitude transformation. Moreover, on the practical side it relates to highlight customer experience and trust which are two main components of the credibility matrix within the mediation effect of advertising campaigns helping to develop a credible branded sector as tourism in the eyes of its users
A Global Mutirão in the Classroom: A National Curriculum Policy for Bangladesh to Build Youth Capacity for Green Jobs in Alignment with the SAA and ACE
No full textTransnational Corporations\u27 Accountability Within the Context of Climate Governance
No full textAs we approach COP30, it becomes more urgent to confront corporate impunity in climate governance more. The contribution of Transnational Corporations (TNCs) in global greenhouse gases emissions is increasing everyday, yet both local institutional structures and legislations -including Investor-State Dispute Settlement (ISDS) systems tend to shield them from accountability for the violations of climate-related human rights and ecocide. The conference plays a great role in such crucial moments by offering negotiators the opportunity to address climate-related crimes committed by TNCs, to align global economic governance with human rights, climate justice, and environment protection by establishing enforceable legal frameworks through multilateral consensuses (‘COP30 Presidency and Bloomberg Philanthropies Announce the COP30 Local Leaders Forum in Rio de Janeiro to Elevate Local Climate Action’, 2025). This policy paper examines the urgency of establishing a binding international mechanism to hold industrial actors accountable, grounded in the ethical and just vision emphasized by this year’s COP Presidency. Observing different cases from the oil extraction industry –Chevron and Shell in Ecuador and Nigeria- and arms and weapons manufacturing industry – Ukrainian and Palestinian wars-, the paper highlights the devastating and long-lasting consequences of weak rule of law and lack of corporate accountability. The paper explores the gaps in international law to deliver justice, and institutional failure in addressing environmental crimes. The paper also discusses the role of technology in evidence-building and compliance with climate monitoring, climate legislations literacy, etc. And finally, this paper concludes from the key findings recommendations on the local and international levels to move towards a better ecological future

Phasing out Fossil Fuels and Accelerating Renewable Energy Resources
No full textThis paper examines the challenges and opportunities in reducing greenhouse gas emissions through the phase out of fossil fuels and acceleration of renewable energy. The 3 areas of interest discussed are: fossil fuel subsidies, electric grid infrastructure and decarbonisation challenges in industrial and transport sectors. The two policy recommendations include development of a national just transition framework and integration of energy storage systems in grids. This paper is directly aimed at governments and policy makers
Empowering Healthcare Providers with AI-Based Climate Health Risk Training
No full textClimate Change (CC) is an emerging threat to human health and livelihood, increasing the burden of health-related illnesses, vector-borne diseases, and non-communicable diseases (NCDs). Due to the gaps in capacity building and education, limited curricula, and time constraints, Health professionals (HCPs) and healthcare students are unprepared to address the climate-health nexus. The urgency for a climate-health training and research in applying ACE principles with digital tools, particularly AI and mobile platforms, in order to reach health care resilient systems. Using global evidence and a real-world case study such as WHO-reported Early Warning and Response System (EWARS), which is piloted in Ethiopia. Demonstrating how AI-based technologies can get health care providers personalized and time efficient training. Recommendations align with the Sharm El-Sheikh Adaptation Agenda and ACE principles to promote accessible, inclusive, and prepared health care systems
