The growing interest in renewable energy sources has led to a significant focus on artificial photosynthesis as means of converting solar into lucrative and energy-dense carbonaceous fuels. First-row transition metals have thus been brought light the search for efficient high-performance homogenous molecule catalysts that can accelerate transformation reduce overpotentials during catalytic process. Their dinuclear complexes opportunities enhance efficiency stability these molecular catalysts, primarily hydrogen evolution reaction (HER) water oxidation (WOR). Recently, our group improved activity, efficiencies, particularly toward HER. Although one complex tested WOR, it demonstrated activity precatalysts. are great option sustainable catalysis because they readily available, reasonably priced, multifaceted coordination chemistry. Examples cobalt, copper, manganese. structure-catalytic performance relationships this first-row metal-based noteworthily interpreted account, providing avenues optimizing their advancing development effective conversion technologies.

Modernizing public transportation is crucial, given the ongoing call for sustainable mobility. Growing concerns about climate change and increasingly stringent emissions standards have compelled transport operators to embrace alternative propulsion vehicles on a broader scale. For past years, Battery Electric Buses (BEBs) been vehicle of choice transportation. However, an emerging contender in this sector Fuel Cell Bus (FCEB). This paper aims evaluate way one such would perform terms energy efficiency while being exploited urban scenario generated from collected data.

Drilling muds play the essential role drilling process as they perform many functions, such removing of drill cuttings and controlling well pressure. Water-based muds, through use more environmentally friendly additives, can meet increased environmental requirements. Many researchers have studied effects different natural materials on mud to find effective materials. The popularity using waste is mainly due their cost favourable impact. Performed literature review showed that rheological filtration characteristics water-based are enhanced with addition leaves various plants trees. This article presents investigations clay-free birch aspen leaf powder. relevant in autumn period, since fallen solid municipal should be disposed by removal landfills. obtained data indicate possibility powder composition. Addition base increases gel strength plastic viscosity mud. In an extent reduces yield point index. Rheological parameters increase 10-30% index decreases up 15-17%.

Analysis of the energy sector from micro perspective that relates to individual companies is much rarer than a macroeconomic analysis concerns power industry as whole and its impact on functioning economy. However, directly implement government’s policies innovation strategies. Thus, this article attempts answer question concerning relationships in three large operating Poland (1) between use renewable resources for production innovative nature company, (2) sources standing stock exchange profitability. This study used multiple case studies, financial indicators, time series analysis, an interdependence analysis. covers 2011–2022 allows consideration long-term changes domestic policy. Our findings suggest there relationship company’s investment activity sources. Unfortunately, scope RESs these small (from ca. 1% 15%, which demonstrates low progress green transformation) has negative correlations with investors’ assessment In relation innovation, ratio intangible assets total was highest Tauron SA, increasing 1.96% 5.16%.

The second place belongs Enea SA increased 0.72% 1.69%. lowest PGE 0.37% 1.47%. results analyzed are strongly affected by policy amendments, including improved status coal re-oriented (prioritizing solar over wind). As result, companies, despite twelve-year period implementation transformation European Union, have achieved little path sustainable energy. Therefore, achieving goal zero-emission economy seems unlikely, since mix still very slight not diversified. Changes conducive sectoral economic innovation.
