We consider the surface pressure of a colloid-laden liquid interface. As micron-sized particles of suitable wettability can be irreversibly bound to the liquid interface on experimental timescales, we use the canonical ensemble to derive an expression for the surface pressure of a colloid-laden interface. We use this…
Non-luminescent crystals of [(C <sub>6</sub> H <sub>11</sub> NC) <sub>2</sub> Au](AsF <sub>6</sub> )·C <sub>6</sub> H <sub>6</sub> readily lose benzene to form the green-luminescent polymorph of [(C <sub>6</sub> H <sub>11</sub> NC) <sub>2</sub> Au](AsF <sub>6</sub> ) rather than the blue-luminescent polymorph.
聚集诱导发光（aggregation-induced emission，AIE）化合物因在生物和化学传感、发光材料、显示等领域具有重要价值而备受关注.作为一类重要的功能分子，有机氟化合物在化学和材料等领域被广泛研究.汇总了具有聚集诱导发光性质的有机氟化合物，并进行了分类讨论.AIE有机氟化合物包括氟代的四苯基乙烯（TPE）衍生物、二苯乙烯基蒽（DSA）衍生物、氰基二苯基乙烯衍生物和二苯乙烯基苯衍生物等常见的AIE化合物，也包括聚合物、碳硼烷簇合物和室温磷光化合物，还有其它一些含氟结构.AIE化合物氟代后，稳定性一般会提高，氟原子参与分子间相互作用，导致聚集态的结构发生改变，从而导致发光性质的改变，如发光增强、发光波长红移（蓝移）或…
A lutetium( <sc>iii</sc> )-porphyrin was designed as a phosphorescent photosensitizer to balance phosphorescence and fluorescence emissions for ratiometric O <sub>2</sub> sensing.

金属纳米结构由于其独特的局域表面等离激元共振现象而倍受关注，对催化、传感、纳米医学以及光学器件等具有重要意义.电荷转移等离激元共振强烈依赖于纳米单元间的导电结点，可产生频率连续可调的共振光吸收和光散射，为获得高度局域化的增强光磁场和光热效应提供了可能.然而，受制于已有构筑手段和有限的结构种类，相关研究仍处于初级阶段.针对此，本工作发展了一种十分简单、有效的Au/Cu纳米异质结点调控策略，利用廉价易得的天然DNA分子在金纳米粒子“种子”表面发生非特异性吸附，有效控制铜在金表面发生异相成核时的相间接触面积，得到导电结点宽度连续可调的电荷转移纳米粒子二聚体.实验光谱和理论模拟显示，结点宽度、铜和金纳米粒子的尺寸是决定电荷转移等离激元性质…
A hierarchical porous PG/CoFe <sub>2</sub> O <sub>4</sub> composite was designed with excellent microwave absorption performance.
In the present work, ZnGa2O4 was incorporated with g-C3N4 nanosheets to synthesize ZnGa2O4/g-C3N4 nanocomposites through the hydrothermal method. The morphologies of nanocomposites were characterized by TEM, XRD, and spectral and electrochemical methods, respectively. The nanocomposites exhibited greatly enhanced fluo…
A new nano-hybrid sheet material using palladium and BSA protein (Pd_NP@BSA <sub>sheet</sub> ) was developed as a sustainable catalyst for C–C coupling reactions in water, as an oxidase enzyme mimic and for the detection of dopamine in buffer, human serum and urine.
Concerns about the environmental impacts due to the end of life for engineered nanomaterials (ENM) are growing.
Recent advances in the practical applications of metallophthalocyanines (MPcs) in different technological fields have stimulated us to design and synthesize a new asymmetric AB3-type trimeric zinc(ii)-phthalocyanine (1). This bulky and high molecular weight compound was characterized by elemental analysis, 1H, 13C DEP…
Polyurethane@activated carbon derived from waste compact disc sponge demonstrated comparable or even better sorption capacity contrasted with other polyurethane-based composites.
Based on the example of the p-type LaAlO <sub>3</sub> /SrTiO <sub>3</sub> interface, we discuss charge-transfer phenomena that tailor the ionic conductivity along oxide heterointerfaces, by providing a confined space-charge layer as channel for oxygen ion conduction.
A modified pulse isotopic exchange technique is proposed to quantitatively evaluate the dissociative adsorption rate of Co-based oxides at high temperature. Their catalytic activity is significantly enhanced by the formation of Co-ion clusters.
Mg(B3H8)2 is a crucial reaction intermediate in the thermal decomposition of the hydrogen storage material Mg(BH4)2 and is discussed as a potential solid-state Mg-ion conductor. We successfully synthesized unsolvated Mg(B3H8)2 and highlight that Mg(B3H8)2 exists mainly as a low-dimensional solid. In addition, the Mg2+…
Composites outdo their basic materials because they combine the best properties offered by each one separately. They have proven their usefulness in many technical applications especially in the production of prostheses for amputees and disabled persons. The purpose of this study is to characterize the structure and m…
Various organelles (e.g., mitochondria and chloroplasts) have a multicompartment structure, providing superior function of material transformation, selective segregation and energy conversion. Enlightened by the elegant evolution of nature, intended isolation of the biochemical process by cooperative multicompartments…
In this paper, we report a one-pot chemical synthesis technique for the preparation of iron and iron-carbide nanoparticles. Mössbauer spectroscopy, X-ray diffraction and magnetometry were used as the main tools to identify the different phases of Fe-C present. The influence of experimental parameters on the structural…
