Transmission electron microscopy (TEM) has a profound impact on knowledge and understanding of bacteria and other microbial populations. The 1000-fold improvement in resolution provided by TEM has allowed visualization of bacterial cells. Of all the types... see more

Te precipitates in CdZnTe (CZT) crystals grown by the traveling heater method (THM) are investigated using high-resolution transmission electron microscopy (HRTEM). The results show that in THM-grown CZT crystals, Te precipitates are less than 10 nm in si... see more

AbstractSperm morphological features play an important role in semen evaluation. Exposure to a variety of chemical compounds, especially environmental endocrine disrupters, elicit abnormalities in sperm of certain species. Baseline data on ultrastructure ... see more

AbstractSperm must remain motile in order to reach and penetrate the ovum and defects in the ultrastructure of the tail can have an adverse influence on motility. Live spermatozoa were collected from the cauda epididymis of 64 impala rams in the Kruger Na... see more

The histological study of lungs in Bidri goat (Capra hircus) and Deccani sheep (Ovis aries) wascarried out to know the structural differences in lungs of these animals. Lungs of both the specieshad respiratory bronchioles, alveolar duct, alveolar sac and ... see more

Physical properties of the polymer can be altered by mixing one or more polymers together also known as polymer blending. The miscibility of polymers is a key parameter in determining the properties of polymer blend. Conventional transmission electron mic... see more

AbstractSince knowledge of sperm morphology can play an important role in semen evaluation and fertilisation, baseline data are required. Live spermatozoa were collected from the cauda epididymis of 64 impala rams in the Kruger National Park and studied b... see more

We present a novel method to determine the projected atomic potential of a specimen directly from transmission electron microscopy coherent electron nano-diffraction patterns, overcoming common limitations encountered so far due to the dynamical nature of... see more

Friction and wear take place on two solid surfaces in sliding contact as a result of the mechanical, thermal, and chemical interactions with the participation of environmental species. These interactions lead to the formation of a tribo-layer or tribofilm... see more
