Eucalyptus globules belonging to the Myrtaceae family was explored for the synthesis of zinc oxide nanoparticles and for biological applications. The aqueous extract of the synthesized zinc nanoparticles (ZnNPs) was characterized using UV-visible spectrophotometer, FTIR, SEM and TEM. The aqueous broth was observed to be an efficient reducing agent, leading to the rapid formation of ZnNPs of varied shapes with sizes ranging between 52–70 nm. In addition, antifungal activity of the biosynthesized ZnNPs was evaluated against major phytopathogens of apple orchards. At 100 ppm of ZnNPs, the fungal growth inhibition rate was found to be 76.7% for Alternaria mali, followed by 65.4 and 55.2% inhibition rate for Botryosphaeria dothidea and Diplodia seriata, respectively. The microscopic observations of the treated fungal plates revealed that ZnNPs damages the topography of the fungal hyphal layers leading to a reduced contraction of hyphae. This considerable fungicidal property of ZnNPs against phytopathogenic fungi can have a tremendous impact on exploitation of ZnNPs for fungal pest management and ensure protection in fruit crops.

“…In the following, we shall deliberate on the efficacy of cryomilling on the synthesis of some of the nanocrystalline oxides. Fabián et al [215] have reported the synthesis of nanocrystalline ZnO using reactive cryomilling. Pure Zn was cryomilled in the presence of oxygen (air) until the coarse Zn was transformed into nanocrystalline ZnO.…”

The milling of materials at cryogenic temperature has gained importance both in academic as well as the industrial community in the last two decades, primarily because of significant advantages this technique as compared to milling at room temperature; environmental friendly nature, cost-effectiveness, rapid grain refinement, less contamination, and large scale production capability of various nanomaterials. Scientifically, milling at cryo-temperature exhibits several distinct material related phenomena; suppression of recovery and recrystallization, predominant fractures over cold welding, significantly low oxidation, and contamination, leading to rapid grain refinement. Cryomilling has extensively been used to obtain finer scale powder of spices for the preservation of aroma, medicines for effective dissolution, or amorphization. It has been considered an environmentally friendly process as it utilizes benign liquid nitrogen or argon without discharging any toxic entity to the environment, making the process attractive and sustainable. The present review is intended to provide various scientific as well as technological aspects of cryomilling, environmental impact, and future direction.

“…Generally, MA process leads to the formation of many advanced materials that are difficult or impossible to be prepared by the traditional methods. [16][17][18][19] Recently, some researchers developed the science of milling under cryogenic temperatures. In this process termed cryomilling, nano-crystalline materials can be synthesized by mechanical milling using liquid nitrogen as the milling medium.…”

In this research, the effect of heating on the mechanical alloying process for synthesizing of titanium carbide was investigated. Raw materials containing pure titanium and graphite powders were milled in different times and temperature. In order to detect phases and properties of synthesized materials X-ray diffraction was applied. Physical properties including density and specific surface area along with microstructure were studied. Results showed that heating can accelerate the mechanical alloying process. By increasing the temperature during milling, production mechanism of titanium carbide changed from self-propagating high-temperature synthesis to gradual model. Changes of density confirmed this phenomenon too. Increasing the milling time leads to particle size and crystal of synthesized titanium carbides became finer down to nanometer scale. Because of higher effective time span of produced titanium carbide, increasing the temperature produces finer particle sizes of powders in similar milling time.
