Benyuan Ma1,2, Haitao Zhao1, Tingshuai Li1, Qian Liu1, Yongsong Luo1, Chengbo Li1, Siyu Lu3, Abdullah M. Asiri4, Dongwei Ma5 (✉), and Xuping Sun1 (✉)

Iron-group (Fe, Co, Ni and Cu) materials are earth-abundant, promising their large-scale applications. This review summarizes recent advances in the design and development of iron-group nitrogen reduction reaction (NRR) electrocatalysts for ambient N2-to-NH3 conversion in aqueous media.

Carbon-based nanozymes for biomedical applications

Hui Ding1, Bing Hu1, Bin Zhang1, Han Zhang3, Xiyun Yan4 (✉), Guohui Nie1 (✉), and Minmin Liang2 (✉)

Carbon nanozymes not only exhibit the physicochemical characteristics of carbon nanomaterials including size, shape, chemical composition, unique optical properties, and large surface area, but also possess enzymatic properties such as peroxidase-like property, catalase-like property, oxidase-like property and superoxide dismutase-like property. Applications of carbon nanomaterials have been greatly expanded by their enzymatic activity, leading to new biomedical applications. This review summarizes the development of chemical modifications and bioconjugate reactions of carbon-based nanozymes, a field of research that holds enormous potential and attracts significant interest in biomedical applications.

Two-dimensional MX Dirac materials and quantum spin Hall insulators with tunable electronic and topological properties

Yan-Fang Zhang1,2,§, Jinbo Pan2,†,§, Huta Banjade2, Jie Yu2, Hsin Lin3, Arun Bansil4, Shixuan Du1 (✉), and Qimin Yan2 (✉)

A novel class of two-dimensional (2D) MX (M = Be, Mg, Zn and Cd, X = Cl, Br and I) compounds with an unbalanced chemical formula was proposed by using data-driven approaches method and first principles calculations. These compounds harbor Dirac states with ultra-high carrier mobilities that are emerged from the interplay of incomplete charge transfer and hexagonal bipartite lattice. Intrinsically being quantum spin Hall insulators, some members of this family could potential host superconductivity in a highly tunable topological matrix.

A new viewpoint and model of neural signal generation and transmission: Signal transmission on unmyelinated neurons

Zuoxian Xiang1,2, Chuanxiang Tang2, Chao Chang1 (✉), and Guozhi Liu2 (✉)

We study the generation and transmission of neural signals at different space and time scales based on quantum optics, electrodynamics and other theories. Through theoretical calculations, there are two types of electromagnetic field signals with different time scales in neurons.

Effect of Zn atom in Fe-N-C catalysts for electro-catalytic reactions: theoretical considerations

Yongcheng Li1, Riming Hu1, Zhibin Chen1, Xin Wan1, Jia-Xiang Shang1 (✉), Fu-He Wang2, and Jianglan Shui1 (✉)

The active sites around Fe and Zn atoms in Fe-Zn-N6(III) show the lowest oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) overpotentials of 0.38 and 0.43 V, respectively. And the bridge site of Fe-Zn in Fe-Zn-N5 shows the lowest ηHER of −0.26 V. The existence of Zn element in the Fe-N-C catalysts plays a key role in reducing the ORR activation energy barrier.

Adaptive ordering and filament polymerization of cell cytoskeleton by tunable nanoarrays

Jing Dai and Yuan Yao (✉)

In this research, we take advantage of nanoarray as matrix to reveal adaptive ordering and filament change of cytoskeleton, such as chemical polymerization, spatiotemporal distribution, and networking entanglements. And this finding also provides an insight on interplay between cytoskeleton reordering and cancer pathophysiology.

Stability enhancement of PbS quantum dots by site-selective surface passivation for near-infrared LED application

Xinsu Zhang1,§, Yujuan Chen1,§, Linyuan Lian2, Zizhen Zhang1, Yixuan Liu1, Li Song1, Chong Geng1 (✉), Jianbing Zhang2, and Shu Xu1 (✉)

A trioctylphosphine-mediated surface passivation approach is developed to improve the air- and photo-stability of PbS quantum dots (QDs). The prepared PbS QDs possess a lead mono-carboxylate capping motif, which effectively passivates the surface S and renders the QDs stable in air, polymer matrices and light irradiation. Infrared LEDs based on the modified PbS QDs display a slight degradation of only 1.47% after continuous operation in air for 250 h.

Flexible synthesis of high-purity plasmonic assemblies

Laurent Lermusiaux†, Anum Nisar, and Alison M. Funston (✉)

Surface functionalisation using deoxyribonucleic acid (DNA) and alkyl-polyethylene glycol (PEG) enables transformation of nanoparticles of different sizes, shapes and materials into readily usable plasmonic building blocks for self-assembly. Assemblies across many different classes in high purity incorporating the different building blocks are formed using electrophoresis purification by manipulation of DNA coverage.
