Abstract

Hierarchically ZnIn2S4 nanosheet-constructed microwire arrays (NCMAs) on a zinc substrate have been synthesized for the first time through a one-step solvothermal method without using any template or surfactant. The as-synthesized ZnIn2S4 microwires are constructed by vertical nanosheets preferentially exposing (006) facets, which are about 1-5 μm in diameters and larger than 10 μm in average length. Experimental results demonstrate that the hierarchically ZnIn2S4 NCMAs are converted from intermediate components of single crystalline indium nanowires, which are generated along the direction of (101) planes by a displacement reaction between Zn and In3+ during the initial synthesis process. This conversion of indium nanowires to hierarchically ZnIn2S4 NCMAs has been explained by a novel corrosion-exchange-self-assembly mechanism, which might indicate a novel strategy for preparing other ternary sulphide nano-microwire arrays. The prepared ZnIn2S4 NCMAs are used as photocatalysts, demonstrating effective photocatalytic degradation activity for diverse organic pollutants including different dyes, tetracycline and 2,4,6-tribromophenol (2,4,6-TBP). This efficient photocatalytic activity is ascribed to the strong absorption of ZnIn2S...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
