26 06 2019There are no published reports on the surface morphology of face masks and the effect of washing and stretching on pore size of the masks In this work we report on the detail study on surface characterization (pore size shape clearance and pore distribution) of commonly available cloth face masks purchased from local market of Kathmandu Nepal and compared with surgical face masks


MORPHOLOGICAL CHARACTERIZATION Knowing the morphology and dimensioning of parts surface layers paints or grains is critical for controlling an industrial process It is therefore important to know or control these parameters in order to validate the methods used in their production • Microscopic observations of the morphology of powders or materials • Macroscopic and microscopic

Morphology and Dislocation Studies 5 1 Introduction A careful study of the surface features of a crystal can reveal the history of its growth The faces of the crystal reflect the characteristics of the growth process Morphology of the crystals depends on the growth rates of the different crystallographic faces In the direction of fastest growth face will be absent the dominant faces are

Surface morphology and optical properties of porphyrin/Au and Au/porphyrin/Au systems Yevgeniya Kalachyova1 Oleksiy Lyutakov1* Andrey Solovyev2 Petr Slepička1 and Vaclav Švorčk1 Abstract Porphyrin/Au and Au/porphyrin/Au systems were prepared by vacuum evaporation and vacuum sputtering onto glass substrate The surface morphology of as-prepared systems and those

This paper describes how a small molecular structure modification can enhance the microscopic and macroscopic properties of chromophore A new chromophore WJ10 is synthesized by applying bromine-termination to the remote donor of WJ6 an existing donor–π–acceptor chromophore This small molecular change can signifi

A Spectral Optical Microscopic Study Synthesis and Characterization of PVC Films Containing Schiff Base Complexes energy gap and surface morphology The optical data recorded that the band gap values are influenced by the type of metals All modified films have a red shift in optical properties in the ultraviolet region The PVC-L-Co(II) was the lowest value of the optical band gap 3 1

While both instruments help characterise microscopic samples they do so in very different ways Optical Microscopy Optical microscopes are the 'traditional' type of microscope in that they use a lens to produce a magnified image For scientific uses optical microscopes can be quite complex however the underlying principle remains the same

induced morphology close to the surface was analyzed by transmission electron microscope polarizing optical microscope and Fourier transform IR spectroscopy Breakup and coalescence of EBR particles scarcely occurred during the injection process The EBR particles near the surface were observed as continuous fibers and were gradually changing to the ellipsoidal shape in the depth direction

We also introduced another nonlinear optical two-photon microscopic technique to image the same coral polyps across the entire thickness of the coral tissues This overcomes the limitations imposed by SBFI in terms of decalcification and the possibility of changes in tissue morphology and volume (shrinking) that may be induced by sample preparation (dehydration) and processing protocols

The surface morphology evaluation of warm laser shock peening was investigated systematically in this work the GH4169 nickel-base super-alloy is selected as the material with which to conduct experiments of laser shock peening and warm laser shock peening It can be found that there are a lot of surface ripples appearing after the treatment of warm laser shock peening which is different from

The optical microscope also referred to as a light microscope is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century Basic optical microscopes can be very simple although many complex

Secondly we quantitatively characterized surface morphology by using atomic force microscopy (AFM) and surface chemical characteristics by performing X-ray photoelectron spectroscopy (XPS) contact angle and surface energy measurements Then we measured the amount of adsorbed proteins on the different nanostructured samples in order to study how surface morphology and surface chemistry
