Land use and land cover (LULC) analysis has become increasingly significant in environmental studies due to its direct impact on the environment. Changes in LULC affect the ecological and climatic balance, in addition to increase the terrain’s susceptibility to hazardous phenomena. However, one of the key challenges in analyzing LULC time series is the presence of classification errors, which can result in invalid transitions. Invalid transitions, which represent unlikely or impossible land cover changes in a given period, can lead to misinterpretations of causes or consequences of hazard events, especially in highly susceptible areas, such as mountainous regions. 

In a paper published in Science Bulletin, Researchers employed a self-assembled monolayer of 4-(9H-carbazol-9-yl)phenylboronic acid (4PBA) as hole-selective contact providing a chemically stable buried interface for Sn-Pb perovskite solar cell. 4PBA can formed a robust and low-corrosive anchoring on the FTO and reduced the energy level mismatch between the perovskite and the substrate through its substantial dipole moment, providing a rapid extraction pathway for hole. Additionally, 4PBA enhanced the interfacial contact between the perovskite and the substrate, improving the crystallization quality of the perovskite, and prevented acid-induced degradation of Tin-Lead perovskite caused by PEDOT:PSS, further minimizing defects in the perovskite device. This strategy offered insights into developing high-efficiency, stable Tin-Lead perovskite solar cells with energy band alignment and interfacial chemical stability.

A study published in the Journal of Medical Internet Research has found that open-world video games can significantly improve relaxation and mental well-being among postgraduate students.

In a paper published in SCIENCE CHINA Chemistry, based on the design of a composite lithium metal anode (Li-10% ZnF₂), the effect of hybrid SEI (LiCl/LiF/LiZn) on the interface between lithium metal anode and sulfide electrolyte was studied. The research results showed that hybrid SEI can effectively induce uniform deposition of lithium ions, inhibit the growth of lithium dendrites, and achieve a more stable anode/electrolyte interface.

In a paper published in SCIENCE CHINA Chemistry, a bifunctional electrocatalytic sulfur matrix that simultaneously accelerates sulfur reduction and ZnS oxidation is proposed to realize a highly efficient Zn-S cell. It is revealed that the N-heteroatom hotspots are more favorable for facilitating the conversion of S to ZnS while the CoO nanocrystal substantially lowers the ZnS activation energy barrier thereby suppressing the formation of disproportionation species (e.g., SO₄²⁻) and accumulation of inactive ZnS.

Standing detonation engines have emerged as the prime power source for highspeed vehicles. While current detonation flow field designs have demonstrated their effectiveness, several hurdles still remain. These include the limited geometric utilization of the combustion chamber and the lack of seamless integration with existing highspeed aerodynamic designs. Selecting the right basic detonation flow field is paramount to enhancing the performance and refining the geometric design of standing detonation vehicles.

Dr. Jwa Eunjin and her research team at the Korea Institute of Energy Research (KIER) have achieved a significant breakthrough in clean energy technology.
