Some of the heavy metals in coal and wastes vaporize during combustion, concentrate in fine particulates, and emit with the flue gas into the atmosphere, to produce adverse effect on environment and health. This study first investigates the fate of the heavy metal species, especially Pb, Cd and Cr, known as semi-volatile, in various flue gases, especially in the presence of HCI and SO2, by chemical equilibrium calculation, in which, Si and Ca were proposed as base sorbent materials to capture Pb, Cd and Cr. Then Si- and Ca-based compounds as well as waste materials used as sorbents were optimized to capture the heavy metals. Finally, the optimal sorbent was tested in actual burning of dried sewage sludge as solid fuel, to evaluate the effectiveness of the sorbent. Calculated results show that Cl increases the volatility of most heavy metals, while SO2 enhances formation of condensed phases. Among the sorbents tested, kaolin appears most efficient to capture Pb and Cd. For sludge combustion with kaolin addition, both Pb and Cd were shifted from sub-micron to macro-sized particles, and accompanied by considerable decrease of 0.1 μm particles.

Diffraction casting

Advanced Photonics 2024年第5期6卷 85-98页

作者： Ryosuke Mashiko Makoto naruse Ryoichi Horisaki The University of Tokyo Graduate School of Information Science and Technology Department of Information Physics and Computing

Optical computing is considered a promising solution for the growing demand for parallel computing in various cutting-edge fields that require high integration and high-speed computational capacity. We propose an optical computation architecture called diffraction casting(DC) for flexible and scalable parallel logic operations. In DC, a diffractive neural network is designed for single instruction, multiple data(SIMD)operations. This approach allows for the alteration of logic operations simply by changing the illumination patterns. Furthermore, it eliminates the need for encoding and decoding of the input and output,respectively, by introducing a buffer around the input area, facilitating end-to-end all-optical computing. We numerically demonstrate DC by performing all 16 logic operations on two arbitrary 256-bit parallel binary inputs. Additionally, we showcase several distinctive attributes inherent in DC, such as the benefit of cohesively designing the diffractive elements for SIMD logic operations that assure high scalability and high integration capability. Our study offers a design architecture for optical computers and paves the way for a next-generation optical computing paradigm.

The orbital phase refers to the relationship between orbitals that originates from their wave character. We show here that the orbital phase essentially determines the diastereoselectivity of the following three organic reactions. 1) Torquoselectivity of the electrocyclicring-opening reaction of 3-substituted cyclobutenes;2) Contradictory torquoselectivity of the retro-Nazarov reaction;3) Diastereoselectivity in electrophilic addition to substituted ethylenes.

胰管细胞HCO_3^-分泌：囊性纤维化跨膜电导调节体和SLC26转运体(英文)

胰管细胞以至少6倍浓度差逆向分泌HCO_3^-(人体浓度约140 mmol/L)。HCO_3^-跨顶膜转运的可能机制包括SLC26阴离子转运体的Cl^--HCO_3^-交换和囊性纤维化跨膜电导调节体(cystic fibrosis transmembrane conductance regulator,CFTR)对HCO_3^-的传导扩散。SLC26家族成员介导上皮顶膜Cl^--HCO_3^-交换,胰管中检测到SLC26A6和SLC26A3。共表达研究揭示,鼠类slc26a6和slc26a3通过slc26的STAS结构域与CFTR的R结构域相互作用,导致活性互相增强。研究显示这些交换体是产电的:slc26a6介导ICl^--2HCO_3^-交换,slc26a3介导2Cl^--1HCO_3^-交换。近期slc26a6-/-小鼠离体胰管研究显示,slc26a6介导大部分Cl^-依赖的HCO_3^-跨顶膜分泌,与slc26a6的产电性一致。然而,因为人体能分泌非常高浓度的HCO3^-,SLC26A6在胰管HCO_3^-分泌中的作用并不十分清楚。SLC26A6的作用只能在与人类似能分泌约140 mmol/L HCO_3^-的物种,如豚鼠中研究。现有的豚鼠研究数据显示,像slc26a6介导的ICl^--2HCO_3^-交换不可能完成这种高浓度差的HCO_3^-分泌。另一方面,CFTR的HCO_3^-电导性可以在理论上支持HCO_3^-逆向分泌。所以,在豚鼠和人胰腺HCO_3^-的分泌中,CFTR可能比SLC26A6发挥更大作用。
