A China-Finland research team underscores the complexities of energy fluxes and the role of cold fronts in lake energy exchange by analyzing Lake Vanajavesi in southern Finland, based on eddy covariance measurements.

New research published in the journal Atmospheric and Oceanic Science Letters reports significant progress in studying the relationship between meteorological conditions and atmospheric fine-particle (PM_2.5) concentrations. In this new study, meteorological fields were obtained using two sets of data to analyze the differences in the simulated PM_2.5 concentration. Results showed that the meteorological field had a strong influence on the concentration levels and spatial distribution of the simulated pollution. Also, one of the data sources resulted in relatively smaller simulation errors, allowing more accurate modeling of PM_2.5 concentrations.

A new study attempts to motivate solar engineers and energy meteorologists alike to push forward with studying and assessing the environmental impacts of large-scale solar farms.

A study led by Dr. DU Xuemin, published in *The Innovation*, has reported a novelphotopyroelectric tweezer that combine the advantages of light and electric fields. Using a rationally designed photopyroelectric substrate with efficient and durable photo-induced surface charge-generation, it enables versatile manipulation in various working scenarios.
