Abstract:
This study aims to examine pollen morphologically via studies of 16 plant taxa from Turkish flora. The pollen structures of the taxa examined, and their microscopic relevance, was discussed and studied with the help of microscopic visualization using scanning and transmission microscopies. Pollen grains were first acetolyzed, and then quantitative and qualitative pollen features were used to evaluate the species. The pollen grains were prolate, spherical, elliptic, tricolporate, 3-colpate, and hexacolpate. Sculpturing patterns of surfaces vary from reticulate, micro-reticulate, and striate regulate. As the findings reveal, palynological data can aid in the taxonomic classification of Turkish floral species. Microscopic implications can be made via micromorphological examination to correctly identify the species. While the pollen morphology of 16 taxa collected from the study area was studied for the first time from this region, the palynological research of some taxa was introduced to the literature for the first time with this study. Pollen morphology and photographic and statistical data of the taxa in our study were determined. This study contributed to bee plant research, melisapalinological studies, and systematic botanical flora studies.

Abstract:
A study on the microscopic morphology of real-world polymer blends and its mechanism of change showed that the microscopic morphology of equiproportional mixtures gradually changed from a dense body structure to a network structure with the addition of the total polymer concentration up to 20%; the microscopic morphology of mixtures with different proportions was characterized by the most uniform network structure of equiproportional mixtures when the total polymer concentration was 20%. The polymer acts as a defoamer in the mixed system. In this paper, the relationship between the microscopic morphology of each mixture and the physicochemical behavior of the two polymer chains in the mixed system was investigated on the basis of the Aifantis strain gradient theory. Molecular polymer microscopic interface and multiscale failure analysis are proposed. It is shown that for the dihedral angle distribution of four consecutive coarse-grained particles, the peaks obtained from all atomic-scale simulation data are reproduced in the coarse-grained model simulations. The deviation is within 2.5% in most places, except for the local area where the deviation exceeds 5%. Therefore, we have achieved good results for large-scale failures.

Full text
Abstract:
Biofouling refers to the unfavourable attachment and accumulation of marine sessile organisms (e.g. barnacles, mussels and tubeworms) on the solid surfaces immerged in ocean. The enormous economic loss caused by biofouling in combination with the severe environmental impacts induced by the current antifouling approaches entails the development of novel antifouling strategies with least environmental impact. Inspired by the superior antifouling performance of the leaves of mangrove tree Sonneratia apetala , here we propose to combat biofouling by using a surface with microscopic ridge-like morphology. Settlement tests with tubeworm larvae on polymeric replicas of S. apetala leaves confirm that the microscopic ridge-like surface morphology can effectively prevent biofouling. A contact mechanics-based model is then established to quantify the dependence of tubeworm settlement on the structural features of the microscopic ridge-like morphology, giving rise to theoretical guidelines to optimize the morphology for better antifouling performance. Under the direction of the obtained guidelines, a synthetic surface with microscopic ridge-like morphology is developed, exhibiting antifouling performance comparable to that of the S. apetala replica. Our results not only reveal the underlying mechanism accounting for the superior antifouling property of the S. apetala leaves, but also provide applicable guidance for the development of synthetic antifouling surfaces.

Abstract:
Light- and electron-microscopic studies were performed on cardiac muscle from rats flown on COS-MOS 2044 and from four control groups. Average cross-sectional area of myofibers was measured by video analysis of the light-microscopic images of papillary and ventricular muscle samples from all animals. This cross-sectional area was significantly decreased in flight rats (P = 0.03) compared with synchronous controls. Additional findings at the electron-microscopic level consistent with this atrophy were obtained by stereological analysis and optical diffraction analysis of papillary muscle samples. Slightly higher mitochondrial volume density values and mitochondria-to-myofibril ratios as well as normal A-band spacings (d1,0) and Z-band spacings of myofibrils were observed in the tail-suspension and flight groups. General morphological features similar to those in ventricular samples from the previous COSMOS 1887 flight were observed.

We describe the synthesis and characterization of aligned carbon nanotubes deposited on quartz substrates by pyrolysis of a xylene–ferrocene mixture at 700 °C at atmospheric pressure. For microscopic characterization of the pyrolyzed products, scanning and transmission electron microscopies and scanning tunneling microcopy were used, and properties of bulk samples were characterized by Raman spectroscopy and x-ray powder diffraction methods. The nanotubes have topological defects and many contain metal particles. Scanning tunneling spectroscopy proved that the nanotubes had a metallic electrical conductivity with resonant states near the Fermi energy. The states are ascribed to the dangling bonds originating from the defects.

Full text
Abstract:
To obtain an understanding of the relationships of the basidiomycetes, especially those with horizontally partitioned metabasidia, and of the evolution of structural characters, members of nine orders and an additional four genera of simple-septate fungi (Auriculariales sensu lato) were studied using cladistic analysis of light microscopic and ultrastructural characters. Comparisons were made with the nucleotide sequence from the 5′ end of the nuclear large subunit ribosomal RNA gene analyzed with several algorithms, including parsimony and maximum likelihood. Analyses of both morphological and molecular characters support similar phylogenetic conclusions, but polarization of some morphological characters was difficult without guidance from molecular data. The Uredinales are shown to be an advanced taxon arising from the simple-septate Auriculariales sensu lato, and some characters that they share with the ascomycetes result from convergent evolution. The simple-septate Auriculariales consists of more than one clade, and the related gasteroid Pachnocybe ferruginea possesses numerous derived light microscopic characters, including holobasidia. Key words: basidiomycetes, character evolution, cladistics, molecular evolution, phylogeny.

Abstract:
Crystallization represents a kind of phase transition, which can be regarded as a process related to bond formation and breaking. According to the chemical bonding characteristics of constituent atoms, the ideal morphology of LiNbO 3 crystals has been successfully predicted by using the chemical bonding theory, which consists well with our experimental results. Some observations concerning the morphology evolution of KH 2 PO 4 (KDP), NH 4 H 2 PO 4 (ADP) and ZnO crystals can also be kinetically simulated by the present theory. The obtained results indicate that the microscopic constituent chemical bonds can help us to comprehensively understand the crystallization mechanism on the basis of quantitative calculations of growth rate in different crystal faces. The chemical bonding theory builds up a link between the crystallographic structure, growth morphology and microscopic chemical bonds of crystal materials, which provides us a useful microscopic tool to quantitatively understand single crystal growth behaviors.

Abstract:
Spherical sponge iron (SSI) with high activity and intension possesses potential characteristics to be utilized as wastewater treatment material, such as higher iron content, uniform particle size, higher compressive strength, etc. Observation on apparent morphology of exterior and microscopic morphology of SSI reduced by hydrogen under different temperature was carried on with SEM. When the reductive temperature was relatively lower than T4, the quantities of iron grain in exterior and interior of SSI increased with the increasing of temperature. When the temperature was elevated to T5, the particle size of iron grain was increased, and lots of macro-holes formed, especially in the interior section of SSI. When the temperature was T4, the SSI possesses more favorable ability to remove pollutant from wastewater. Moreover, the iron content in SSI was mostly reach to the summit under this temperature. In summarization, the reduction temperature should be controlled under T4 temperature if the sponge iron was utilized in wastewater treatment.

Full text
Abstract:
Nuclear speckles are compartments enriched in splicing factors present in the nucleoplasm of eucaryote cells. Speckles have been studied in mammalian culture and tissue cells, as well as in some non-mammalian vertebrate cells and invertebrate oocytes. In mammals, their morphology is linked to the transcriptional and splicing activities of the cell through a recruitment mechanism. In rats, speckle morphology depends on the hormonal cycle. In the present work, we explore whether a similar situation is also present in non-mammalian cells during the reproductive cycle. We studied the speckled pattern in several tissues of a viviparous reptile, the lizard Sceloporus torquatus, during two different stages of reproduction. We used immunofluorescence staining against splicing factors in hepatocytes and oviduct epithelium cells and fluorescence and confocal microscopy, as well as ultrastructural immunolocalization and EDTA contrast in Transmission Electron Microscopy. The distribution of splicing factors in the nucleoplasm of oviductal cells and hepatocytes coincides with the nuclear-speckled pattern described in mammals. Ultrastructurally, those cell types display Interchromatin Granule Clusters and Perichromatin Fibers. In addition, the morphology of speckles varies in oviduct cells at the two stages of the reproductive cycle analyzed, paralleling the phenomenon observed in the rat. The results show that the morphology of speckles in reptile cells depends upon the reproductive stage as it occurs in mammals.

The authors point out that in this regard, a special place is occupied by the microscopic analysis of refractory materials, because the use of various radiation and various designs of microscopes from optical to electronic requires various special preparation of objects and special methods for deciphering the observed images. Moreover, the use of these methods in relation to the fire-resistant compositions obtained during the experiments, consisting of kaolin, wollastonite, soda water glass, silica, finely dispersed thermovermiculite, silicon dioxide, dolomite, etc., demonstrates their microrelief morphology, which gives rise to other experiments related to increasing the quality of fire resistance of the objects under study.

Full text
Abstract:
Apple pomace pectins, extracted using various methods (water, cellulase, arabinase, and arabinase with mannanase), and commercial apple pectin were studied, analyzing their morphology and chemical structure. The microscopic analysis revealed morphological differences, with a log-normal particle size distribution observed in most samples, except for those extracted with water. Cellulase-extracted pectin exhibited the most spherical morphology, while enzymatically extracted pectins displayed uneven surfaces. The FT-IR analysis indicated structural changes, shifts in O-H bands, and the degree of methoxylation (DM) ranged from 30.25% to 58%, with all the pectins classified as high-methoxy pectins. The NMR (1H and 13C) analysis confirmed the presence of arabinans, galactans, galacturonans, and rhamnose, and the calculated DM and acetylation (DAc) values were consistent with the results obtained using conventional methods. These results provide insight into the influence of extraction methods on pectin properties, which is relevant to the pharmaceutical and food industries, and confirm the structural similarity between enzymatically extracted pectins and commercial pectin.

Abstract:
Pollen is appropriately referred by some as Golden dust extremely valuable on account of their tremendous applications in science, industries and public health. No other plant part even though extremely tiny in size is packed with so much information and power. Similar to other plant parts, pollen characters are so varied that the classification system of plants can be built up entirely on the basis of pollen morphology.Palynology is the distinct branch of biology that deals with the dispersed microscopic tiny living and fossil entities including pollen grains, spores, algal and fungal fragments and others. An important aspect of Palynology is the Pollen morphology. The importance of Palynology in taxonomic and phylogenetic consideration of plants is well known. The changes occurring through hybridization and years of cultivation are reflected in pollen morphology. The scope and interest in the study of pollen morphology have widened with the advent of Scanning Electron Microscopy (SEM) and with regards to unipalynous taxa particularly the understanding of finer morphology is of fundamental importance. SEM gives a correct understanding of exine surface as the electron photographs of the surface replica of the exine provides the exact picture of the ornamentation pattern. The variation in the pollen morphological characters helps in the classification of plant taxa and their assessment of their phylogenetic relationship. In the present investigation, the pollen morphological studies were carried out of some ethnomedicinal plants like Catharanthus roseus, Allamanda cathartica, Datura metel, Brassica juncea, Raphanus sativus and Cleome viscosa pollen grains by Scanning electron microscopy. All that they possess anticancer characteristics in common.

Full text
Abstract:
Environmental scanning electron microscopic observations of Postia placenta grown on a defined medium and on red spruce wood allowed for the examination of the hydrated sheath of P. placenta. In the wood environment, mature hyphae that were not adhering to the substrate were observed to have a mycofibrillar morphology whereas hyphal tips and branch points had a smooth sheath morphology. A mycofibrillar adhesive matrix was observed on the hyphae growing on glass slides in the defined medium. These morphologies for hyphal sheaths in P. placenta are similar to those previously described by investigators from other laboratories who have used traditional electron microscopic preparative protocols that include dehydration steps. The potential future usefulness of environmental scanning electron microscopic technology in the study of the fine details of extracellular matrices is briefly discussed.Key words: mycofibrils, hyphal sheath, environmental scanning electron microscopy, extracellular matrix.

Abstract:
Freezing is an effective technology with which to maintain food quality. However, the formation of ice crystals during this process can cause damage to the cellular structure, leading to food deterioration. A good understanding of the relationship between food microstructure and ice morphology, as well as the ability to effectively measure and control ice crystals, is very useful to achieve high-quality frozen foods. Hence, a brief discussion is presented on the fundamentals/principles of optical microscopic techniques (light microscopy), electronic microscopic techniques (transmission electron microscopy (TEM) and scanning electron microscopy (SEM)), as well as other non-invasive techniques (X-rays, spectroscopy, and magnetic resonance) and their application to measuring ice formation rates and characterizing ice crystals, providing insight into the freezing mechanisms as well as direct monitoring of the entire process. And, in addition, this review compares (the negative and positive aspects of) the use of simple and cheap but destructive technologies (optical microscopy) with detailed microscopic technologies at the micro/nanometer scale but with pretreatments that alter the original sample (SEM and TEM), and non-destructive technologies that do not require sample preparation but which have high acquisition and operational costs. Also included are images and examples which demonstrate how useful an analysis using these techniques can be.

Abstract:
The stomach of fish provides the first stages of food digestion, as well as adaptation to specific ecosystems and food resources, which is important for the ecology and protection of fish biodiversity. studying the structure of the stomach at the macro- and microscopic level is one of the urgent problems of ichthyomorphology, veterinary and Fisheries practice. However, modern studies on the morphology of the stomach of fish are mainly devoted to pathological changes in infectious and invasive diseases, the impact of adverse environmental factors, conditions of detention, and anthropogenic load. The aim of the work is to conduct a scientific review on the study of the morphology of the stomach of normal fish. Electronic search for publications has been conducted in the web of Science, Scopus, PubMed and Google Scholar databases, mainly over the past 20 years. The principles of objectivity and a comprehensive attitude to the study of the chosen problem are used. The authors of the review article review the current scientific literature and summarize current knowledge on the morphology of the stomach of fish of various classes and species. The anatomical structure of the fish stomach is described taking into account its anatomical areas. The classification of fish stomachs depending on their shape is presented. According to the description of the microscopic structure of the fish stomach, the structural components of its membranes are characterized. The microscopic structure of the surface and glandular epithelium of the mucous membrane is presented, the types of gastric glands and their localization are indicated, and the micromorphology of the layers of the muscle membrane is described. Information from the histochemical study of the stomach of fish of various species is considered. In general, the described anatomical features of the stomach of fish are relevant both for the comparative anatomy of fish of different classes. Data on the microscopic structure of the structural components of the gastric membranes of fish are of practical importance for assessing the morphofunctional state of fish of a certain species and age, which is important for the scientific substantiation of technologies for their cultivation and mastering the mechanisms of development of diseases of the digestive system. Histochemical characteristics of the stomach of fish can serve as a theoretical basis for the development of a normal stomach test system for detecting functional changes under the influence of environmental factors.

Abstract:
Objectives: To clarify the morphology of the tongue papillae formation and the metabolic characteristics along the papillae distribution in rats. Methods: The experiment was designed as a cross-sectional study and included; a scanning electron and light microscopic examination, connective tissue core analysis, and an enzyme activity test on rat tongue samples of the embryonic (n = 60) and postnatal (n = 12) periods. Results: The primordium of fungiform papillae (FuP) was already formed on embryonic day 15 (E15), and filiform papillae (FiP) was formed on E17. In the postnatal period, the middle and posterior parts of the tongue quickly developed toward the anterior part of the oral cavity. Three types of FiP were found: round, conical and branched. According to the enzyme activity test, all energy, lipid, protein and sugar metabolic enzymes showed significant differences along the tongue parts. Conclusion: No positional difference was found in the morphology of rat tongue papillae during the embryonic period. During the postnatal period, the morphology and enzyme activities of the tongue mucosa displayed differences expressing tongue development and its functional characteristics among the described tongue parts—listed above.

Abstract:
The evolution of the morphology/structure and the nonlinear viscoelasticity of rubber blends under large amounts of strain are key scientific issues for the design and manufacture of rubber blends. The rheological responses of natural rubber/styrene-butadiene rubber (NR/SBR) blends are traced over a wide range of blend compositions to gain an insight into the effect of blend morphology on their nonlinear viscoelasticity. We also prepare NR + SBR physical blends without melt mixing to distinguish the contributions of composition and blend morphology to the viscoelastic response. The microscopic heterogeneous gel-like structure of NR/SBR blends may remarkably weaken their strain softening and improve their modulus hysteretic recovery under large strain, which may be attributed to the heterogeneous microscopic deformation for the NR and SBR phases. Furthermore, additional elastic contribution resulted from the increasing interfacial energy of domain deformation. This may provide some new insights into the effect of blend morphology on the Payne effect of rubber blends.

Abstract:
Bacterial morphology is critical in determining how these ubiquitous organisms function and behave. This study delved into the intriguing world of bacterial morphologies, offering thorough research regarding microorganisms' variable shapes and structures. It sheds light on the distinct traits and functions associated with their morphologies. Initially, the study highlighted the most common bacterial morphologies, ranging from the traditional rod and cocci to more complex patterns, including spirals, helices, and flat-wave structures. Each morphology revealed the structural traits that separate one from another. Moreover, a particular focus was placed on emerging advancements in the field, from conventional to recent advances in microscopic technologies that provided unique insights into microbial architecture. Furthermore, the review emphasized the importance of bacterial surface appendages, including flagella and pili, influencing microbial behavior and interactions. For instance, the corkscrew-like motion of helical bacteria is investigated in motility, emphasizing its importance in the survival and adaptability of specific species. Furthermore, in the realm of microscopic technologies, various options exist. However, recent literature revealed that scanning electron microscopy (SEM), field-emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) stand out as the most advanced microscopic techniques. Specifically, advancements such as super-resolution microscopy techniques, including structured illumination microscopy (SIM) and stochastic optical reconstruction microscopy (STORM), have revolutionized our understanding of pathogenesis and drug delivery. In conclusion, this review strengthens our understanding of bacterial morphologies while emphasizing the importance of taking a more diverse approach to investigating microbial structures. The combination of traditional knowledge and cutting-edge microscopy opens up new possibilities for discovery, promising a better understanding of bacterial shape and its consequences in scientific and medical fields.
