A photocatalytic process was developed for intermolecular reductive coupling of aliphatic ketones with alkynes/alkenes to furnish tertiary alcohols. Mechanistic studies support that boron carbonitrides(BCN) promote the single electron reduction of unactivated aliphatic ketones to generate ketyl radicals with visible light irradiation, which then react with alkynes and alkenes to afford the allylic and aliphatic alcohols, respectively. The heterogeneous photocatalytic system is compatible with diverse substrates including pharmaceutical-related molecules(43 examples) with reusability and scale-up experiments, verifying the complementary synthetic utility of this method to the homogeneous catalysts.

针对原有同态滤波算法在处理亮度低、细节部分区别不明显的矿井监控视频图像时,容易造成图像整体处于偏暗状态,且会丢失部分暗区域细节信息这一问题,提出一种适用于矿井监控视频图像增强的改进同态滤波算法。首先使用引入的改进同态高通滤波与所提出的同态低通滤波对煤矿井下监控设备得到的图像进行处理,然后加权融合;为修正此时图像的亮度并减少后续处理图像的时间,选择将得到的图像转换到HSV空间下,在保持色调分量H不变的情况下,对亮度分量V采用CLAHE进行校正。由于亮度的变化会对饱和度分量S造成影响,因此对饱和度分量S进行自适应非线性增强;最后将得到的图像反转回RGB空间下完成矿井监控视频图像的增强。实验结果显示:在保证图像不失真且不改变图像原有色彩结构的情况下,对比其他3种算法,该算法能更好地提升图像整体亮度和对比度,同时能避免光晕现象的产生,且保真性良好,增强一幅图像只需1.1 s左右。

Historical forest and grassland cover changes not only are critical indicators for quantifying ecological and environmental change processes but also serve as fundamental data for long-term climate change simulations and terrestrial ecosystem carbon emission assessments. However, because of limitations in historical data, quantitative estimations and spatially gridded reconstructions of these changes remain challenging, necessitating further methodological exploration. This study focused on China's present-day land area over the past millennium, objectively capturing the characteristics and drivers of forest and grassland cover changes. On this basis, using the forest transition theory and the space-for-time substitution method, we depicted the historical deforestation process as an inverted “S” curve and developed a model to reconstruct historical forest area changes based on the functional relationship between the forest area and population size dynamics. Subsequently, a gridded forest allocation model was established on the basis of deforestation tendencies. For the grassland cover, we implemented regionspecific methods, such as the cropland area deduction method and the habitat constraint method, to quantitatively reconstruct historical changes. Consequently, we obtained provincial forest and grassland area changes over the past millennium and mapped 10-km-resolution gridded data of forest and grassland cover. The results indicated the following.(1) The methods developed using population data as a proxy objectively reproduced the spatiotemporal evolution of forest and grassland cover in China over the past millennium. These feasible methods offer a novel pathway for the quantitative reconstruction of historical forest and grassland cover changes.(2) The data indicated that China's forest area generally decreased over the past millennium, characterized by a “decrease-then-increase” pattern. The forest area experienced three distinct phases: a slow decline(AD 1000
