Three new species of the genus Craspedomerus from China are described and illustrated: C. giganteus Li & Zhou sp. n. from Sichuan, C. gongshanus Li & Zhou sp. n. from Yunnan and C. zhangi Li & Zhou sp. n. from Tibet. Four species are reported for the first time from China: C. sinetuber (Coiffait, 1977a) from Tibet, C. cyanipennis Scheerpeltz, 1976b, C. ganeshensis Coiffait, 1983 and C. glenoides (Schubert, 1908) from Yunnan. These four and two additional species previously recorded from China (C. beckeri Bernhauer, 1934 and C. violaceipennis Cameron, 1928 are redescribed and illustrated. Sensory peg setae located on the underside of the paramere of the aedeagus of all nine Chinese species are compared using scanning electron microscopy (SEM) and the result shows that this character is useful for species identification. A key to the Chinese species of Craspedomerus is presented and geographical distribution of all sixteen species of Craspedomerus is mapped.

Study of type and other material using scanning electron microscopy has permitted the recognition of three new species and one new genus of Arctic and boreal calloporid anascans. Originally described from the Gulf of St Lawrence, Callopora whiteavesi is reassigned to Flustrellaria, a calloporid genus not previously reported extant. Material from north-east Greenland misidentified as C. whiteavesi is described as C. weslawski sp. nov. The new genus Septentriopora is introduced for calloporids lacking pore chambers, with a distolateral pair of small interzooidal avicularia that face proximally or proximolaterally, and a reduced ovicell. The type species of Septentriopora, Tegella nigrans, has frequently been misidentified. Many of the supposed records of this species belong to two other species, described here as Septentriopora karasi sp. nov. and S. denisenkoae sp. nov. The apparent ovicell in S. karasi is particularly unusual, being vestigial and kenozooid-like in morphology.

Portanus adenomari sp. nov. from the Brazilian states of Minas Gerais, Paraná, and Maranhão is described and illustrated. It can be easily distinguished by the aedeagus with a pair of apical, slender curved processes, crossing each other medially. The previously unknown females of Portanus restingalis Felix & Mejdalani, 2016 and Metacephalus facetus (Kramer, 1961), as well as the female terminalia of Metacephalus sakakibarai Souza, Takiya & Felix, 2017, are also described in detail. Scanning electron microscopy (SEM) images of the ovipositor valvulae of P. restingalis are given. Comparative notes on the morphology of the female terminalia in the tribe Portanini are provided. Specimens of P. restingalis were observed feeding and resting on Bromeliaceae leaves; this is the first record of host plants for the Portanini. Metacephalus marica (Felix & Mejdalani, 2016) is regarded as a junior synonym of Metacephalus longicornis (Osborn, 1923).

Three new species of Ulnaria from the Wuling Mountains Area, China, have been studied by light and scanning electron microscopy. All possess at least six closed girdle bands. The pattern of valve striation is not uniform as some do not have a corresponding opposite structure. The cells of Ulnaria sinensis sp. nov. are linked and form colonies with frustules connected by interlocking linking spines. U. sinensis has very long valves (296–512 µm) and uniseriate striae. Both Ulnaria ulnabiseriata sp. nov. and Ulnaria gaowangjiensis sp. nov. have biseriate striae. U. ulnabiseriata differs from U. gaowangjiensis in LM by its more lanceolate valve shape as the valves of U. ulnabiseriata taper towards the pole from one third of the length of the valve, whist U. gaowangjiensis tapers towards the pole from two thirds of the length of the valve, and by its larger valve length (105–229 µm vs 61–108 µm). The three new species are all epilithic and were found in freshwater streams in or near nature reserves.

A new species of Cribraria, described herein as C. bicolor, appeared in moist chamber cultures on samples of the bark of Eucalyptus sp. collected at two localities in Australia. The morphology of representative specimens was examined by light and scanning electron microscopy, and micrographs of relevant morphological details of sporocarps and spores are provided. The species has a number of distinct and unique morphological features, including a glossy bright-violet globose sporotheca and a two-colored long stalk which is bright-red over the lower one-third and light yellow or lemon-yellow over the upper two-thirds. The combination of these characteristics as well as a shallow calyculus which is dark-violet when viewed under a dissecting microscope and bright red in transmitted light when mounted in lactophenol makes C. bicolor a well-defined morphospecies when compared to all other species of Cribraria. The stability of the taxonomic characters of the species was confirmed by an examination of a number of specimens.

Several imaging methodologies have been used in biofilm studies, contributing to deepening the knowledge on their structure. This review illustrates the most widely used microscopy techniques in biofilm investigations, focusing on traditional and innovative scanning electron microscopy techniques such as scanning electron microscopy (SEM), variable pressure SEM (VP-SEM), environmental SEM (ESEM), and the more recent ambiental SEM (ASEM), ending with the cutting edge Cryo-SEM and focused ion beam SEM (FIB SEM), highlighting the pros and cons of several methods with particular emphasis on conventional SEM and VP-SEM. As each technique has its own advantages and disadvantages, the choice of the most appropriate method must be done carefully, based on the specific aim of the study. The evaluation of the drug effects on biofilm requires imaging methods that show the most detailed ultrastructural features of the biofilm. In this kind of research, the use of scanning electron microscopy with customized protocols such as osmium tetroxide (OsO4), ruthenium red (RR), tannic acid (TA) staining, and ionic liquid (IL) treatment is unrivalled for its image quality, magnification, resolution, minimal sample loss, and actual sample structure preservation. The combined use of innovative SEM protocols and 3-D image analysis software will allow for quantitative data from SEM images to be extracted; in this way, data from images of samples that have undergone different antibiofilm treatments can be compared.

A new species, Encyonema oblonga Liu & Xie, is collected during a survey of the freshwater diatom flora of Manghe River, Shanxi, China. The valves of this new species are oblong with rounded apices and have the features typical of Encyonema, including complex areolae. We compare the new species with the most similar taxa, E. leei, E. leei var. sinensis and E. appalachianum and consider that  E. leei var. sinensis is the valid name.  The morphology of E. oblonga is documented with light and scanning electron microscopy.

A novel fabrication process is presented to create ultra thick ferromagnetic structures in silicon. The structures are fabricated by electroforming NiFe into silicon templates patterned with deep reactive ion etching (DRIE). Thin films are deposited into photoresist molds for characterization of an electroplating cell. Results show that electroplated films with a saturation magnetization above 1.6 tesla and compositions of approximately 50/50 NiFe can be obtained through agitation of the electrolyte. Scanning electron microscopy (SEM) images show that NiFe structures embedded in a 500 μm thick silicon wafer are realized and the roughening of the mold sidewalls during the DRIE aids in adhesion of the NiFe to the silicon.
