Abstract Geodiversity and geoheritage studies are multidisciplinary, drawing from all sides of geosciences and extending them into the humanities, geoarchaeology, spatial planning, territorial and risk management, economics, tourism, or culture using integrated and interdisciplinary research approaches. During the last three decades, geodiversity and geoheritage research experienced a considerable growth that confirms both scientific and public relevance of these topics. In this introductory text, a brief review of current literature is presented and the importance of geodiversity and geoheritage for sustainable development, geohazard resilience and associated themes is discussed. Last, but not least, the aims and structure of this volume are outlined.

In the past decade, metal halide perovskites grew from a mere scientific sensation to a tangible photovoltaic technology, being on the brink of commercial entrance. Certified efficiency value reported for these devices exceeded 25%. However, there still remains a large scope for further advancement, particularly in better understanding of the formation process of polycrystalline thin films of these materials. Insight into the interplay between colloidal precursor solution and nucleation of perovskite crystallites is highly desirable to obtain well‐controlled crystallization process, essential for reproducible manufacturing at large scale. Herein, a novel synthetic route of methylammonium iodide (CH3NH3I, MAI) is reported, which produces ultrapure material with a cheap and simple method. MAI prepared this way obtains better control over the perovskite precursor colloidal solution. Furthermore, MAPbI3 perovskite layers processed from solutions are formulated with different MAI powders, and these films are applied into a simple planar heterojunction solar cell stack. Through photovoltaic performance characterization and multiple spectroscopic measurements, superior optoelectronic properties of samples made with an optimized solution are demonstrated. The influence of a precursor solution and its colloidal distribution on the final film properties is reported. The reported synthetic protocol is also applicable to other alkylammonium iodides.

Glony mogą być wykorzystywane do produkcji różnych rodzajów biopaliw. Należą do nich biogaz produkowany w wyniku beztlenowego rozkładu biomasy glonów, a także biodiesel oraz bioetanol powstający z oleju pozyskiwanego z alg. W pracy dokonano przeglądu literatury dotyczącej metod hodowli glonów oraz możliwości produkcji z ich biomasy biopaliw płynnych i gazowych.

In terms of energy efficiency and the quality of the indoor and outdoor environment, heritage buildings are facing sustainability challenges. This study assessed the feasibility of using renewable energy sources based on air-to-water heat pumps with regard to preserving the historic values of the buildings and their ability to coexist with current energy efficiency and decarbonization requirements, and to prevent their neglect and degradation. A new approach is the use of Building Information Modelling to accurately determine energy demand and select a heating system based on renewable energy sources in such an unusual case as a heritage building. The analysis covers a selection of feasible scenario of the modernization of the over 300 years old building. A particular focus of the study is to compare the use different heat pumps systems. One is a reversible gas absorption air-to-water heat pump and the other is an electricity-powered compressor air-to-water heat pump. The building is currently supplied with a fixed-temperature boiler up to 550 kW with an open combustion chamber fed with coal. It was proven that the proposed retrofit scenario reduces final energy demand by 72.9%, while improving thermal comfort, cutting annual emissions by 121.1 Mg CO2 and 1.0 Mg PM10.

Climate change has been posing an increasing threat to the planet at the environmental and economic levels, and the rise of clean energy (CE) is ever more fundamental for ensuring a qualified alternative for the energy mix, attracting the financial interest of different investment entities. In this respect, the significance of corporate venture capitalists (CVCs) has been on a steady rise for every sector, even for CE, since the 1990 s, and it is shaping up to become a major force behind the worldwide innovation. The aim of this research is to investigate the essential profiles about the phenomenon regarding CVCs that are active in CE, with a focus on the Asia-Pacific (APAC) region, to understand how they act in pursuing their strategic intention. The specific contribution of this study, which adopts a quantitative approach to operate a descriptive analysis on the dynamics operating in the context under investigation by combining relating data from several institutional databases, is to provide a scenario analysis with explorative intention that may define the main characteristics, roles in innovation, and growing participation of CVCs in the CE sector, especially in the APAC area.
