Osteochondral tissue has a complex layered structure that is not self-repairing after a cartilage defect. Therefore, constructing a biomimetic gradient scaffold that meets the specific structural requirements of osteochondral tissue is a major challenge in the field of cartilage tissue engineering. In this study, chitosan/Sodium beta-glycerophospha...

A procedure was developed for in vitro propagation of Rosa genotypes along with an efficient de novo shoot organogenesis (DNSO) method. We tested, on one genotype (hybrid of Rosa wichurana), the effects of MS basal medium complemented with two growth regulators to achieve either shoot elongation or shoot multiplication of plants. These media were c...
A discussion of current issues on the environmental safety of spent tires and the existing possibilities of their further processing and utilization, as well as a modern solution to the environmental problem.
In this study, composite scaffolds with different multi-walled carbon nanotubes (MWCNTs) content were prepared by freeze-drying. These scaffolds were characterized by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), porosity, hydrophilicity, mechanical strength, and degradatio...

The production of lithium-ion battery is around 9100 million sets in 2016 and is believed to further increase consecutively. This fact triggers the generation of spent cathode materials which contain metals of both valuable and hazardous. Their recycling corresponding to life cycle sustainability of lithium-ion battery has attracted significant att...

A V2O5-WO3/TiO2-coated type of honeycomb catalyst was tested in a pilot-scale plant for DeNO(x) of the flue gas from a coal-fired glass kiln at temperatures of 250-310 degrees C for a cumulative period of 2500 h. The catalyst exhibited a two-stage deactivation feature: a gradual activity reduction in the first 1100 h followed by an accelerated deac...
