[目的]选取亚热带地区10年生杉木人工林,探究其叶片性状对土壤P添加的响应以及叶片磷组分随P添加的分配模式变化,为提高杉木人工林生产力提供一定的科学依据。[方法]选定3块样地,在每块样地设置6个处理,每个处理随机施P量分别为0(CK)、60(P1)、120(P2)、180(P3)、240(P4)、300(P5)kg·hm^(−2)·a^(−1),进行为期3年的模拟P沉降控制实验。研究了比叶面积(SLA)、叶干物质含量(LDMC)、叶氮(N)、叶磷(P)、N/P、叶片最大净光合速率(A_(max))、光合氮磷利用效率(PNUE、PPUE)和核酸磷(nucleic acids)、脂质磷(phospholipids)、代谢磷(metabolic)、残渣磷(residual)、无机磷(Pi)的响应及其相关性。[结果]与CK相比较,P2、P3处理下SLA增加了37.9%、25.7%,LDMC减少了9.4%、12.5%;不同梯度土壤P添加下叶N含量无显著差异,但叶P含量比CK增加29.4%~49.4%,N/P相对CK减少18.2%~27.3%;P3处理下PNUE、PPUE和A_(max)均达到最大值,相对CK分别增加174.9%、116.4%、125.9%;除P2、P3处理外,叶片磷组分更倾向于增加核酸磷比例,P3处理主要偏向于增加代谢磷分配,而且代谢磷和PNUE呈现正相关也表明其是叶片净光合速率提高的重要因素。[结论]P3处理下的A_(max)最高,显著提高了PNUE和PPUE,可以有效缓解杉木的P限制状况,促进了杉木的生长发育。

New perspectives in free nitrous acid (FNA) uses for sustainable wastewater management

The biocidal effects of free nitrous acid (FNA) have found applications in multiple units in an urban wastewater system, including sewer networks, wastewater treatment processes, and sludge treatment processes. However, these applications are associated with chemical costs as both nitrite and acid are needed to produce FNA at the required levels. The recent discovery of novel acid-tolerant ammonia oxidizers offers the possibility to produce FNA from domestic wastewater, enabling the development of next-generation FNA-based technologies capable of achieving self-sustaining FNA production. In this study, we focus on the concept of in situ FNA generation facilitated by acid-tolerant ammonia oxidizers and highlight the multiple benefits it creates, after a brief review of the historical development of FNA-based technologies. We will discuss how wastewater systems can be made more energy-efficient and sustainable by leveraging the potential of acid-tolerant ammonia oxidizers.

The Potential Game-Changer:A Concept-to-Proof Study on D:A Heterojunction-Free Organic Photovoltaics

Chinese Journal of Chemistry 2024年第3期42卷 252-258页

作者： Lijian zuo Sae Byeok Jo Xueliang shi Francis Lin Alex Jen State Key Laboratory of Silicon and Advanced Semiconductor Materials MOE Key Laboratory of Macromolecular Synthesis and FunctionalizationDepartment of Polymer Science and EngineeringZhejiang UniversityHangzhouZhejiang310058 China Department of Materials Science and Engineering University of WashingtonSeattleWAUSA School of Chemical Engineering Sungkyunkwan University (SKKU)Suwon16419 Republic of Korea School of Chemistry and Molecular Engineering East China Normal UniversityShanghai200062 China Department of Materials Science and Engineering City University of Hong KongKowloonHong KongChina Department of Chemistry City University of Hong KongKowloonHong KongChina Hong Kong Institute for Clean Energy Hong KongChina

Since 1986,the donor-acceptor (D:A) heterojunction has been regarded a necessity for high-efficiency organic photovoltaics (OPVs),due to its unique advantage in compensating the intrinsic limitations of organic semiconductors,such as high exciton binding energy and poor ambipolar charge mobility. While this adversely causes tremendous non-radiative charge recombination and instability issues,which currently become the most critical limits for commercialization of OPVs. Here,we present a concept-to-proof study on the potential of D:A heterojunction free OPV by taking advantage of recent progress of non-fullerene acceptors. First,we demonstrate that the “free carriers” can be spontaneously generated upon illumination in an NFA,i.e.,the 6TIC-4F single layer. Second,the 6TIC-4F layer also exhibits good ambipolar charge transporting property. These exceptional characteristics distinguish it from the traditional organic semiconductors,and relieve it from the reliance of D:A heterojunction to independently work as active layer. As a result,the subsequent OPV by simply sandwiching the 6TIC-4F layer between the cathode and anode yields a considerably high power conversion efficiency ~1%. Moreover,we find the D:A heterojunction free device exhibits two order of magnitude higher electroluminescence quantum efficiency and significantly reduced VOC loss by 0.16 eV compared to those of the D:A BHJ structure,validating its promise for higher efficiency in the future. Therefore,our work demonstrates the possibility of using D:A heterojunction-free device structure for high performance,that can potentially become the next game changer of OPV.
