Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.

癌症形成于促炎症状态的微环境之中,遵循着"变异-选择-适应"的达尔文进化规律。这一过程的遗传学基础是体细胞突变的产生与积累。目前,大量体细胞突变的产生机制以及环境压力下变异细胞的自然选择过程尚不明确。载脂蛋白B mRNA编辑酶催化多肽(apolioprotein B mRNA-editing enzyme catalytic polypeptide,APOBEC)家族是一类高效的胞苷脱氨酶,其转录可被促炎症细胞因子和趋化因子激活,并在人体的固有和获得性免疫机制中发挥重要作用。APOBECs家族在抑制病毒复制的同时,也驱使有促癌作用的病毒突变体形成;其基因编码功能还可以诱发有促癌作用的驱动突变产生。作为在炎-癌转化中发挥桥梁作用的标志性酶,APOBECs家族对癌症的进化发育至关重要。

为探明使用替代饲料麦蛾Sitotroga cerealella卵饲养的东亚小花蝽Orius sauteri在释放前是否有必要针对其主要防治对象——蓟马、蚜虫、叶螨进行短期食物驯化,以及进行短期食物驯化对其捕食能力的影响。本试验以西花蓟马Frankliniella occidentalis、玉米蚜Rhopalosiphum maidis、二斑叶螨Tetranych usurticae为猎物,全程饲喂麦蛾卵的东亚小花蝽雌成虫为处理A,提前2 d饲喂猎物的东亚小花蝽雌成虫为处理B,研究了2种处理的东亚小花蝽在不同猎物密度(5、15、30、50头)下的捕食功能反应。结果发现,无论是否经过短期食物驯化,东亚小花蝽对3种猎物在不同猎物密度捕食功能反应均符合HollingⅡ型反应模型。处理A对3种猎物的平均时间均低于处理B,东亚小花蝽雌成虫处理每头西花蓟马的时间Th分别为0.024 d和0.031 d,玉米蚜分别为0.081 d和0.103 d,二斑叶螨为0.078 d和0.090 d。由此可知,以麦蛾卵作为替代饲料人工饲养的东亚小花蝽,在释放前不需要针对猎物进行短期食物驯化;在东亚小花蝽规模化生产中,麦蛾卵是一种优良的替代饲料。

我国中小学体育学习评价的发展相对滞后,现阶段中小学体育学习评价中仍然存在着评价主体单一、评价内容陈旧、缺乏人文关怀等问题。积极心理学是20世纪末在西方兴起的一股重要的心理学力量,更是心理学界兴起的一个新的研究思路。本文运用文献资料法、逻辑分析法等方法从积极心理学的研究内容入手,分析积极心理学对中小学体育学习评价产生的影响,获得推动中小学体育学习评价改革发展的启示。中小学体育学习评价应从单一主体向多元主体转变,关注学生的情绪体验;摒弃机械化的评价内容,促使学生形成积极的个人品质;实现体育学习评价的多样功能,培养学生健康的心理素质;选用多种体育学习评价方法,形成积极的班级人际环境。
