1. Photoelectric effect accelerated electrochemical corrosion and nanoimprint processes on gallium arsenide wafers

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC01978B



Scientists at Xiamen University report that corrosion can be accelerated by the photoelectric effect, which could be useful for nanoimprint lithography. The team find that charge transfer is enhanced when GaAs wafers are illuminated by a xenon light source. In the presence of electrolyte solution, this accelerates anodic corrosion of the GaAs at a phase boundary. This could lead to efficient, low-cost nanoimprinting in the semiconductor industry.


厦门大学的研究人员发现光电效应可以加速腐蚀,这可能可以用于纳米压印光刻技术。该团队发现GaAs晶片在被氙光源照射时,电荷转移增强。在电解质溶液中,这会加速相界处GaAs的阳极腐蚀。该发现有助于开发半导体工业中有效且低成本的纳米压印技术。

2. Catalase-like metal–organic framework nanoparticles to enhance radiotherapy in hypoxic cancer and prevent cancer recurrence

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC00747D



A team of researchers from China have developed enzyme-like MOF nanoparticles that effectively inhibit melanoma growth and prevent tumor postoperative recurrence with only one X-ray irradiation after intravenous injection. The MOF contains hafnium and an enzyme-like ligand, which can absorb X-ray energy, convert O2 and H2O into reactive oxygen species to induce cell apoptosis and catalytically decompose endogenous H2O2 into O2 for enhancing radiotherapy in hypoxic tumors.


山东师范大学的研究人员开发了一种类酶MOF纳米颗粒,经静脉注射后只需一次X射线照射,即可有效抑制黑色素瘤的生长并预防肿瘤术后复发。该MOF材料中含有铪和一种类酶配体,能够吸收X射线能量,将O2H2O转化为活性氧从而诱导细胞凋亡,并将内源性H2O2催化分解为O2,促进缺氧肿瘤的放射治疗。

1. Progress in air-processed perovskite solar cells: from crystallization to photovoltaic performance

Mater. Horiz., 2019, Advance Article

DOI: 10.1039/c9mh00325h



This review article summarizes the recent progress made in air-processed organometallic halide perovskite (OHP) solar cells. Specifically, we focus on (1) the microscopic understanding of the impact of the ambient environment on the crystallization process of OHP composites, (2) the approaches to control the crystallization and morphology of OHP in ambient air, and (3) the fabrication processes to achieve highly efficient air-processed OHP solar cells. Finally, we will discuss the challenges and pathways toward commercialization of low-cost air-processed OHP solar cells.

2. Constructing metal–organic framework nanodots as bio-inspired artificial superoxide dismutase for alleviating endotoxemia

Mater. Horiz., 2019, Advance Article

DOI: 10.1039/c9mh00339h



Herein, for the first time, bio-inspired Cu-TCPP MOF dots (CTMDs) were fabricated via a facile liquid exfoliation strategy; they could functionally and structurally mimic the antioxidant superoxide diamutase for alleviating endotoxemia with the ability of renal enrichment and clearance. Both in vitro and in vivo results demonstrated that the CTMDs could efficiently remove reactive oxygen radicals, protect cell components and reduce the systemic inflammation and mortality in lipopolysaccharide-induced acute kidney injury during the endotoxemia model.


本文首次通过简便的液体剥离策略制备了仿生Cu-TCPP MOF点(CTMD),它们可以从功能和结构上模拟抗氧化剂超氧化物歧化酶以缓解内毒素血症,同时具有肾脏富集和清除的能力。体外和体内实验结果均表明,在内毒素血症模型中,CTMD能够有效去除活性氧自由基,保护细胞组分并减少脂多糖诱导的急性肾损伤的全身炎症和死亡率。

3. Novel small-molecule electron donor for solution-processed ternary exciplex with 24% external quantum efficiency in organic light-emitting diode

Mater. Horiz., 2019, Advance Article

DOI: 10.1039/c9mh00373h



Herein, we designed and synthesized a novel small-molecule electron-donor with good solubility and film-forming ability. Further, by utilizing the strategy of ternary exciplexes to improve the reverse intersystem crossing efficiency, a solution-processed exciplex OLED was achieved with a high external quantum efficiency of 24%. The outstanding feature presented in this work can provide a good reference for the future development of high-efficiency exciplex OLEDs.

Polymer Chemistry (IF: 4.927)



1. Fluorescent electronic tongue based on soluble conjugated polymeric nanoparticles for the discrimination of heavy metal ions in aqueous solution

Polym. Chem., 2019, 10, 2256-2262

DOI: 10.1039/C9PY00033J



Authors created an ‘electronic tongue’ for rapid heavy metal ion sensing in aqueous solutions. They arranged fluorescent soluble polymeric nanoparticles in an array. When in the presence of positively charged heavy metal ions photoinduced electron transfer (PET) occurred and the fluorescence was quenched. As the array had a range of different conjugated polymers in it and each metal ion had distinct quenching behaviour (influenced by the size and charge of the ion) the results were analysed to create an 18 dimensional vector unique to each metal ion.


作者创造了一种在水溶液中进行快速重金属离子传感的“电子舌”。他们将荧光可溶性聚合物纳米颗粒排成阵列,当正电荷重金属离子存在时,发生光诱导的电子转移(PET)以及荧光猝灭。由于该阵列具有一系列不同的共轭聚合物,并且每种金属离子具有不同的猝灭行为(受离子的尺寸和电荷影响),因此分析结果之后即可得到与每一种金属离子都能够对应的18维向量(6种传感器 × 3个RGB值)。
