Artif Cells Nanomed Biotechnol 2021 Dec;49(1):381-389

Department of Bioengineering, Faculty of Chemical and Metallurgical Engineering, Yıldız Technical University, Esenler-Istanbul, Turkey.

Many of the bioactive substances used in pharmaceutical industry are easily affected by temperature, light and oxygen, and are easily degraded during storage and processing, and exhibit poor adsorption properties during digestion, which limits their direct use. Microalgae are rich in oils which have antimicrobial properties and antioxidants that attract attention in both food and pharmaceutical sectors in recent years. Studies to encapsulate bioactive compound-rich microalgae oils with nanotechnological approaches to improve the physical and chemical stability are relatively new, and it is promising to apply these approaches for pharmaceutical purposes.

Photocatalytic Surface Restructuring in Individual Silver Nanoparticles.

ACS Catal 2021 Mar 3;11(6):3478-3486. Epub 2021 Mar 3.

DIFFER-Dutch Institute for Fundamental Energy Research, De Zaale 20, 5612 AJ Eindhoven, The Netherlands.

Light absorption and scattering by metal nanoparticles can drive catalytic reactions at their surface via the generation of hot charge carriers, elevated temperatures, and focused electromagnetic fields. These photoinduced processes can substantially alter the shape, surface structure, and oxidation state of surface atoms of the nanoparticles and therefore significantly modify their catalytic properties. Information on such local structural and chemical change in plasmonic nanoparticles is however blurred in ensemble experiments, due to the typical large heterogeneity in sample size and shape distributions.

Nanotechnology 2021 Apr 15. Epub 2021 Apr 15.

Beihang University, Beijing, CHINA.

Tin oxide (SnO2) was considered as a promising alternative to commonly used graphite anode in energy storage devices thanks to its superior specific capacity. However, its electrochemical property was severely limited due to the inherent poor conductivity and drastic volume variation during charging/discharging process. To overcome this disadvantage, we grew Sn-MOF directly on graphene oxide (GO) layers to synthesize a double carbon conductive network-encapsulated SnOnanoparticles (SnO/C/rGO) via a facile solvothermal method.

Underlying Mechanisms for the Modulation of Self-Assembly and the Intrinsic Fluorescent Properties of Amino Acid-Functionalized Gold Nanoparticles.

Langmuir 2021 Apr 15. Epub 2021 Apr 15.

Discipline of Chemistry, Indian Institute of Technology Indore, Indore 452020, Madhya Pradesh, India.

The origin of the blue fluorescence of proteins and peptides in the visible region has been a subject of intense debate despite several efforts. Although aromatic amino acids, namely tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) are responsible for the intrinsic luminescence of proteins and peptides, the underlying mechanism and contributions of these amino acids to the unusual blue fluorescence are still not well resolved. In the present endeavor, we show that the clusterization of both aromatic and aliphatic amino acids on the surface of the gold nanoparticles (Au NPs) leads to clusteroluminescence, which could be linked to the unusual fluorescence properties of the proteins and peptides and have been ignored in the past.

A Review on Recent Progression of Modifications on Titania Morphology and its Photocatalytic Performance.

Acta Chim Slov 2020 Jun;67(2):361-374

Titanium dioxide (TiO2) has been broadly used as a photocatalyst because it has good stability and performance for degradation of pollutants. On the other hand, its efficiency as photocatalyst is limited since it can only be excited under UV-light radiation and has a rapid electron-hole recombination that occurs during the photodegradation. There are many studies focusing on adjusting the synthesis methods, addition of dopants and modifying the TiO2 structure to enhance its photocatalytic performance. Read More

Interwoven MOF-Coated Janus Cells as a Novel Carrier of Toxic Proteins.

ACS Appl Mater Interfaces 2021 Apr 14. Epub 2021 Apr 14.

A Center for Intelligent Microprocess of Pharmaceutical Synthesis Department of Chemical Engineering, Pohang University of Science and Technology (POSTECH), Pohang 37673, Republic of Korea.

Two major issues in cell-mediated drug delivery systems (c-DDS) are the availability of free cell surfaces for the binding of the cells to the target or to their microenvironment and internalization of the cytotoxic drug. In this study, the Janus structure, MOF nanoparticles, and tannic acid (TA) are utilized to address these issues. Janus carrier cells coated with metal-organic frameworks (MOFs) are produced by asymmetrically immobilizing the nanoparticles of a MOF based on zinc with cytotoxic enzymes that are internally encapsulated on the surface of carrier cells.

Zeolite-Encapsulated Ultrasmall Cu/ZnO Nanoparticles for the Hydrogenation of CO to Methanol.

ACS Appl Mater Interfaces 2021 Apr 14. Epub 2021 Apr 14.

School of Materials Science and Engineering, Tianjin Key Laboratory of Metal and Molecule-Based Material Chemistry, National Institute for Advanced Materials, Nankai University, Tianjin 300350, China.

Selective hydrogenation of CO to methanol is a "two birds, one stone" technology to mitigate the greenhouse effect and solve the energy demand-supply deficit. Cu-based catalysts can effectively catalyze this reaction but suffer from low catalytic stability caused by the sintering of Cu species. Here, we report a series of zeolite-fixed catalysts Cu/ZnO()@Na-ZSM-5 ( is the mass ratios of Cu/Zn in the catalysts) with core-shell structures to overcome this issue and strengthen the transformation.

Université de Strasbourg, Université de Haute Alsace, Institut de Science des Matériaux, IS2M-CNRS-UMR 7361, 15 Rue Jean Starcky, 68057, Mulhouse, France.

In the present study, five NPs (containing ZnO, Au-ZnO, Cu-ZnO, TiO, and Au-TiO) were characterized using dynamic light scattering and transmission electron microscopy, in order to observe their behavior under environmental change. The applicability of NPs for degradation of three polycyclic aromatic hydrocarbons (PAHs), including benzo(a)pyrene, fluoranthene, and benzanthracene, using UV irradiation showed the high photocatalytic efficiency of doped NPs for the removal of the study pollutants. To predict the environmental impact and interaction between NPs and PAHs on marine organisms, Mytilus galloprovincialis mussels were exposed to concentrations of each chemical (50 and 100 μg/L) for 14 days.

Both multilayered (ML) and few-layered (FL) TiCT nanosheets have been prepared through a typical etching and delaminating procedure. Various characterizations confirm that the dominant terminal groups on ML-TiCT and FL-TiCT are different, which have been assigned to O-related and hydroxyl groups, respectively. Such deviation of the dominant terminals results in the different physical and chemical performance and eventually makes the nanosheets have different potential applications. Read More
