The overall photocatalytic CO_(2) reduction reaction(OPCRR)that can directly convert CO_(2) and H_(2)O into fuels represents a promising renewable energy conversion *** a typical redox reaction,the OPCRR involves two half-reactions:the CO_(2) reduction half-reaction(CRHR)and the water oxidation half-reaction(WOHR).Generally,both half-reactions can be promoted by adjusting the wettability of ***,there is a contradiction in wettability requirements for the two ***,CRHR prefers a hydrophobic surface that can accumulate more CO_(2) molecules on the active sites,ensuring the appropriate ratio of gas-phase(CO_(2))to liquid-phase(H_(2)O)***,the WOHR prefers a hydrophilic surface that can promote the departure of the gaseous product(O_(2))from the catalyst surface,preventing isolation between active sites and the reactant(H_(2)O).Here,we successfully reconciled the contradictory wettability requirements for the CRHR and WOHR by creating an alternately hydrophobic *** was achieved through a selectively hydrophobic modification method and a charge-transfer-control ***,the collaboratively promoted CRHR and WOHR led to a significantly enhanced OPCRR with a solar-to-fuel conversion efficiency of 0.186%.Notably,in ethanol production,the catalyst exhibited a 10.64-fold increase in generation rate(271.44μmol g^(-1)h~(-1))and a 4-fold increase in selectivity(55.77%)compared to the benchmark *** innovative approach holds great potential for application in universal overall reactions involving gas participation.

The efficiency of photocatalytic CO_(2) reduction reaction(PCRR)is restricted by the low solubility and mobility of CO_(2) in water,poor CO_(2) adsorption capacity of catalyst,and competition with hydrogen evolution reaction(HER).Recently,hydrophobic modification of the catalyst surface has been proposed as a potential solution to induce the formation of triple-phase contact points(TPCPs)of CO_(2)(gas phase),H_(2) O(liquid phase),and catalysts(solid phase)near the surface of the catalyst,enabling direct delivery of highly concentrated CO_(2) molecules to the active reaction sites,resulting in higher CO_(2) and lower H+surface *** TPCPs thus act as the ideal reaction points with enhanced PCRR and suppressed ***,the initial synthesis of triple-phase photocatalysts tends to possess a lower bulk density of TPCPs due to the simple structure leading to limited active points and CO_(2) adsorption ***,based on constructing a hydrophobic hierarchical porous TiO_(2)(o-HPT)with interconnected macropores and mesopores structure,we have significantly increased the density of TPCPs in a unit volume of the *** with hydrophobic macroporous TiO_(2)(o-MacPT)or mesoporous TiO_(2)(o-MesPT),the o-HPT with increased TPCP density leads to enhanced photoactivity,enabling a high methanol production rate with 1111.5μmol g^(−1) h^(−1) from *** results emphasize the significance of high-density TPCPs design and propose a potential path for developing efficient PCRR systems.

平菇（Pleurotus spp.）是全球最广泛栽培的蘑菇品种之一。本研究旨在探讨合生元对Pleurotus ostreatus和Pleurotus pulmonarius生长和品质的影响。通过每日对蘑菇样品喷洒不同浓度的合生元，测量其生长参数、产量、生物效率、近似成分、矿物质含量、总酚含量和二苯基-1-三硝基苯肼（DPPH）自由基清除活性。结果表明，使用喷洒菊粉和干酪乳杆菌的合生元，平菇的产量最高（56.92克），生物效率也最高（12.65%）。菊粉和干酪乳杆菌的组合最为高效，可以同时提高两种样品蘑菇的生长性能和营养成分。此外在白平菇（***）中，菊粉和干酪乳杆菌组合的合生元可产生最高的总酚含量（20.550 mg GAE/g DE），而在灰蘑菇（P. pulmonarius）中产生最高总酚含量的是干酪乳杆菌（1.098 mg GAE/g DE），其次是菊粉和干酪乳杆菌（1.079 mg GAE/g DE）。DPPH结果表明，平菇可以作为一种有效的抗氧化剂。综上，合生元可通过增加酚类化合物的含量来提高蘑菇的抗氧化能力，并通过增加矿物质元素的含量来提供更好的健康益处，从而提高了蘑菇的品质。上述研究证明了合生元作为一种生物肥料用于蘑菇栽培的应用潜力，是帮助蘑菇种植者解决质量不稳定的一个有效方案。

当前，以数据驱动为基础的自适应学习技术在教育领域展现出了巨大的潜力，然而其不透明的“黑箱”属性引发了教育研究者和实践者的普遍担忧。可解释性人工智能被认为有潜力在自适应学习情境中帮助学习者理解干预决策，从而提升学习成效，但其在教育应用中的实践效果存在争议。为此，文章采用元分析方法，对29项实证研究的66个效应量进行分析，发现可解释性人工智能对自适应学习的学习效果的提升为中等程度，其中对学习者认知和元认知维度的影响更大；可解释性人工智能的促进作用因受到解释设计、呈现设计、实验设计的影响而存在差异。基于研究结果，文章提出未来的自适应学习干预应坚持以学习者为中心，注重学习干预解释的互动性、可读性和边界性等启示，以促进可解释性人工智能在教育领域的深度应用。

在确保NaOH对小麦秸秆预处理效果的前提下,通过适当延长预处理时间可减少NaOH用量,进而降低二次污染风险,为小麦秸秆的户用沼气生产提供理论依据。采用自行设计的厌氧发酵装置,研究不同NaOH预处理质量分数和预处理时间对小麦秸秆常温(20℃)厌氧发酵效率的影响。结果显示,在小麦秸秆常温厌氧发酵时,NaOH质量分数为3%时的预处理效果优于质量分数为0和6%的预处理效果;在预处理7~28 d时,纤维素、半纤维素和木质素的脱除率分别为3.66%~8.07%、43.08%~46.43%和47.88%~51.44%;发酵时的初始pH值为8.36~8.47,108~113 d发酵基本完成,累积产甲烷1 565.80~1 833.16 mL,干物质累积产甲烷体积为97.86~114.57 mL/g,产甲烷速率为13.86~16.97 mL/d,甲烷体积分数为50%~58%的持续时间为57~72 d。通过响应面模型试验得到最优预处理条件为:NaOH质量分数为4.36%,预处理时间为12.44 d。该条件下干物质甲烷产量的实测值为113.76 mL/g,与预测值接近,相对误差小于5%,表明模型有效。综合判断,在小麦秸秆常温(20℃)厌氧发酵时,利用质量分数为4.36%(以秸秆干重计)的NaOH对秸秆进行预处理切实可行。

2023年,传播学与符号学多维度融合的趋势正在进一步深化。本文从基础理论、焦点话题、话语体系、方法论四个维度对这一年国内外传播符号学进展提供一个不完全观察。在理论基础方面,“传播之真”等经典论题在新语境下的信息论与意义论的对话中得到拓展。这一年的新媒介焦点话题是AI——以Chat GPT为代表的大语言模型在媒介平台中的应用引发的传播符号学分析,正在催生出“准主体性”以及“后叙事性”等一系列新理论。文化向来是传播符号学的重点研究领域。基于中华文化的“符号考古”与国际学术界关注的“中国叙事”有成为中国传播学自主知识体系建设的新突破的趋势。此外,作为方法论的“传播符号学”正在为包括艺术在内的多媒介、跨体裁文本提供新的话语阐释方法。符号学正在成为传播学不可分割的一个整体,而作为整体的“传播符号学”作为传播学的人文学典型范式在新的理论语境下展现其理论生命力。
