Determinants of emissions pathways in the coupled climate-social system

Frances C. Moore et al.

Summary: The ambition and effectiveness of climate policies play a crucial role in determining greenhouse gas emissions and the scale of climate change impacts. However, most climate change models treat the socio-politico-technical processes that determine climate policy and emissions trajectories as external factors. This study identifies relevant feedback processes and connects them in a stylized model of the climate-social system. The analysis of the model reveals potential nonlinearities and tipping points in the connections across different scales, which can significantly influence policy and emissions outcomes. Public perceptions of climate change, the future cost and effectiveness of mitigation technologies, and the responsiveness of political institutions emerge as important factors in explaining variations in emissions pathways and constraints on warming.

Revealing an elusive metastable wurtzite CuFeS2 and the phase switching between wurtzite and chalcopyrite for thermoelectric thin films

Hong Pang et al.

Summary: In this study, a rarely reported metastable wurtzite-type phase of CuFeS2 thin film was successfully obtained and a phase transition between the metastable wurtzite and the chalcopyrite phase was observed. The phase change significantly affected the thermoelectric properties. It was found that the wurtzite phase could be recovered and stabilized between room temperature and 473 K. Additionally, the reduced thermal conductivity of the thin film compared with bulk was demonstrated, which was correlated with the polycrystal sizes.

A Comprehensive Review on Current Performance, Challenges and Progress in Thin-Film Solar Cells

Santhosh Sivaraj et al.

Summary: Due to the increased demand for silicon, thin-film photovoltaic modules have the potential for significant market penetration. Compared to rigid solar cells, thin-film PV technologies have the flexibility to adapt to any curvature. Stability issues, reflection losses, and advancements in electrode and dopant materials pose challenges to the development of solar materials for improved efficiency. Solar cells have evolved into first, second, and third generation based on the photoactive materials used over time. In this review, the working mechanisms, materials used, drawbacks, and stability issues of different solar cells are extensively discussed. Thin film solar cells can absorb certain elastic deformations due to their flexible nature. Multi-junctional solar cells exhibit enhanced efficiency. Among third-generation solar cells, the perovskite/Si tandem architecture achieves a maximum efficiency of approximately 29%.

Summary: The study shows that publications on green energy and environmental technologies have grown exponentially, with China, the USA, and Italy being the most active countries, but global cooperation is not closely knit at present. The research frontier identification results indicate that categories such as energy, wastewater, and performance are stable, while catalyst and CO2 emission categories show a clear shift, suggesting that catalytic production of clean energy, strategies to reduce greenhouse gas emissions, and related studies are the research frontiers to address global energy crisis and environmental problems.

Iron-Content-Dependent, Quasi-Static Dielectric Resonances and Oxidative Transitions in Bornite and Chalcopyrite Copper Iron Sulfide Nanocrystals

Soohyung Lee et al.

Summary: By manipulating the iron content of bornite-phase copper iron sulfide nanocrystals, tunable optical characteristics from visible to near-infrared can be achieved, attributed to two different types of resonant excitations. Decreasing the iron content in the nanocrystals leads to a reduction in the intensity of quasi-static dielectric resonance and an increase in hole-induced localized surface plasmon resonance in the near-infrared.

Summary: The phase diagram of the Fe-Sb-S system predicts phase separation below 540 degrees C, but incorporating Fe into the Sb2S3 host lattice using a molecular precursor approach may lead to the production of new magnetic materials. Single-source precursors were used to prepare Sb2(1-x)Fe2xS3 powders, and the morphology, composition, and optoelectronic properties varied with the mole fraction of the iron precursor.

The role of new energy in carbon neutral

Zou Caineng et al.

Summary: Carbon dioxide is an important component in the global carbon cycle, with dual properties of converting organic matter in ecosystems and contributing to the greenhouse effect. Achieving carbon neutrality is a consensus, but faces challenges in politics, resources, technology, market, and energy structures. Carbon replacement, emission reduction, sequestration, and cycling are key approaches, with carbon replacement as a crucial aspect. New energy sources like solar, wind, hydro, nuclear, and hydrogen power play a major role in achieving low carbon emissions, with green hydrogen serving as a reserve force. Artificial carbon conversion technology acts as a bridge between new and fossil energy sources to reduce emissions effectively. China is predicted to reach peak carbon dioxide emissions of 110x10(8) t in 2030, but could potentially decrease to 22x10(8) t, 33x10(8) t, and 44x10(8) t by 2060 under various scenarios. To achieve carbon neutrality, implementing a new energy structure and promoting energy independence strategy are essential in China.
