Controlled modification of surfaces is one of the key pursuits of the nanoscience and nanotechnology fields. In article number 1903184, Kostya (Ken) Ostrikov and co‐workers from the Queensland University of Technology propose a concept which can enhance the capacity for the control of surfaces: plasma‐assisted nucleation and self‐assembly at atomic to nanoscales, scalable at atmospheric pressure....
A type of heavy‐metal‐free metal‐semiconductor Au‐ZnSe hybrid nanorod is reported by Shaobin Wang, Yunguo Li, Guohua Jia, and co‐workers in article number 1902231. Au particles grow nonepitaxially on the end facets of wurtzite ZnSe nanorods producing Au‐tipped ZnSe hybrid nanorods, which can be used as non‐toxic and eco‐friendly catalysts for hydrogen production through water splitting.
In article number 1903572, In Young Kim, Ajayan Vinu, and co‐workers discover thermodynamically stable C3N7 composed of tetrazine, triazole and guanidine moieties. Its structure is buckled due to electrostatic repulsion between nitrogen atoms. This study proves that nitrogen atoms in the tetrazine moiety of C3N7 are very effective in the adsorption of O2 species for the oxygen reduction reaction....
Mesoporous noble metals and their patterning techniques for obtaining unique patterned structures are highly attractive for electrocatalysis, photocatalysis, and optoelectronics device applications owing to their expedient properties such as high level of exposed active locations, cascade electrocatalytic sites, and large surface area. However, patterning techniques for mesoporous substrates are still...
An efficient way to improve the electrocatalyst and Li–O2 battery performances of metal oxide is developed by an exquisite synergistic control over structural disorder and surface bonding nature. The effects of amorphous nature and surface chemical environment on the functionalities of metal oxide are systematically investigated with well‐crystalline and amorphous MnO2 nanocrystals with/without surface...
Introducing ferromagnetism in transition metal dichalcogenides has attracted lots of attention due to the possible applications in spintronics devices. Generally, single magnetic element doping is used to introduce magnetism. However, mostly, weak ferromagnetism is observed. In this work, codoping of two kinds of transition metals (Nb and Co) into WSe2 is used to study its magnetic properties. In...
Compositional interplay of two different cobalt phosphates (Co(H2PO4)2; Co‐DP and Co(PO3)2; Co‐MP) loaded on morphologically engineered high surface area nanocarbon leads to an increased electrocatalytic efficiency for oxygen evolution reaction (OER) in near neutral conditions. This is reflected as significant reduction in the onset overpotential (301 mV) and enhanced current density (30 mA cm−2 @...
Conductive films that are highly transparent and flexible are extremely attractive for emerging optoelectronic applications. Currently, indium‐doped tin oxide films are the most widely used transparent conductive films and much research effort is devoted to developing alternative transparent conductive materials to overcome their drawbacks. In this work, a novel and facile approach for fabricating...
Design and development of efficient photocatalysts for H2 production from water and sunlight have gained significant attention as the solar assisted approach is considered to be a promising approach for the generation of clean fuel. However, the poor charge carrier separation and light harvesting ability of existing photocatalysts limits the efficiency of photoconversion of water. In this work, the...
Complete blood count with leukocyte (white blood cell, WBC) differential is one of the most frequently ordered clinical test for disease diagnosis. Herein, multifunctional fluorescent carbon dots derived from biomolecules (biodots) for rapid lysis‐free whole blood analysis are developed. Specifically, two types of biodots are molecularly engineered through hydrothermal synthesis for differential blood...
Transparent conducting oxides (TCO) have integral and emerging roles in photovoltaic, thermoelectric energy conversion, and more recently, photocatalytic systems. The functional properties of TCOs, and thus their role in these applications, are often mediated by the bulk electronic band structure but are also strongly influenced by the electronic structure of the native surface 2D electron gas (2DEG),...
Controlled modification of surfaces is one of the key pursuits of the nanoscience and nanotechnology fields, allowing for the fabrication of bespoke materials with targeted functionalities. However, many surface modifications currently require painstakingly precise and/or energy intensive processing to implement, and are thus limited in scope and scale. Here, a concept which can enhance the capacity...
A reactive oxygen species (ROS)‐sensitive degradable polymer would be a promising material in designing a disease‐responsive system or accelerating degradation of polymers with slow hydrolysis kinetics. Here, a thermogelling poly(ethylene glycol)–polycaprolactone–poly(ethylene glycol) (PEG–PCL–PEG or EG12–CL20–EG12) triblock copolymer with an oxalate group at the middle of the polymer is reported...
Carbon nitrides with a high N/C atomic ratio (>2) are expected to offer superior basicity and unique electronic properties. However, the synthesis of these nanostructures is highly challenging since many parts of the CN frameworks in the carbon nitride should be replaced with thermodynamically less stable NN frameworks as the nitrogen content increases. Thermodynamically stable C3N7 and C3N6...
In article number 1903265, Yong‐Mook Kang, Seong‐Ju Hwang, and co‐workers develop an efficient way to improve the electrocatalyst and Li–O2 battery performances of metal oxide via synergistic control of structural disorder and surface bonding nature. The amorphization and iodate anchoring are quite effective in improving electrocatalyst/electrode functionalities of δ‐MnO2 via the alteration of surface...
Liquid metals are emerging as fluidic inorganic materials in various research fields. Micro‐ and nanoparticles of Ga and its alloys have received particular attention in the last decade due to their non toxicity and accessibility in ambient conditions as well as their interesting chemical, physical, mechanical, and electrical properties. Unique features such as a fluidic nature and self‐passivating...
Developing a highly active, stable, and efficient non‐noble metal‐free functional electrocatalyst to supplant the benchmark Pt/C‐based catalysts in practical fuel cell applications remains a stupendous challenge. A rational strategy is developed to directly anchor highly active and dispersed copper (Cu) nanospecies on mesoporous fullerenes (referred to as Cu‐MFC60) toward enhancing oxygen reduction...
An unprecedented microwave‐based strategy is developed to facilitate solid‐phase, instantaneous delamination and decomposition of graphite fluoride (GF) into few‐layer, partially fluorinated graphene. The shock reaction occurs (and completes in few seconds) under microwave irradiation upon exposing GF to either “microwave‐induced plasma” generated in vacuum or “catalyst effect” caused by intense sparking...
Controlled self‐assembly of biomolecules on graphene offers a pathway for realizing its full potential in biological applications. Microscopy has revealed the self‐assembly of amino acid adlayers into dimer rows on nonreactive substrates. However, neither the spontaneous formation of these patterns, nor the influence of amino acid termination state on the formation of patterns has been directly resolved...
