Horodyskia has been found at a single Tasmanian locality, in the Cassiterite Creek Quartzite (ca. 13-8 Ma), part of a thick Proterozoic, mildly deformed, low greenschist facies, marine shelfal siliciclastic succession known as the Rocky Cape Group. The rock hosting the fossils is thinly interbedded and interlaminated dark grey slaty shale and quartzose siltstone. The sharp-based, graded siltstone layers are interpreted as distal storm surge deposits on an outer marine shelf. The 'strings of beads' are mostly preserved at the base of the siltstone layers, in concave hyporelief (external moulds) on the soles of the event beds, and as convex.

Horodyskia williamsii new species, a Mesoproterozoic macrofossil from Western Australia
A new species of abundant macrofossil, previously described informally as a 'string of beads', is here assigned to the genus Horodyskia Yochelson and Fedonkin 2, and formally named Horodyskia williamsii. It is known from Mesoproterozoic siliciclastic rocks that are older than 17 Ma and younger th...


An enigmatic non-marine thalloid organism from the Triassic of East Antarctica
An enigmatic thallophyte (Litothallus ganovex gen. et sp. nov.) occurs in the form of compressions with cellular preservation and associated sheets of complete cells in non-marine Triassic deposits in the Transantarctic Mountains, Antarctica. A combination of microscopic techniques (i.e. bright f...
Coaxial Electrospinning of Self-Healing Coatings
Self-healing polymer coatings are formed by electrospinning bead-on-string healing agent filled capsules onto a substrate followed by infilling of a polymer matrix. Upon damage to the self-healing coating, liquid healing agents are released from the ruptured beads passivating the damaged region, ...


Preparation of microcellular polypropylene/polystyrene blend foams with tunable cell structure
By using supercritical carbon dioxide (sc-CO2) as the physical foaming agent, microcellular foaming was carried out in a batch process from a wide range of immiscible polypropylene/polystyrene (PP/PS) blends with 1-7 wt% PS. The blends were prepared via melt processing in a twin-screw extruder. T...

Fossil bacteria from the Permotriassic Trappean strata of Siberia
The strata of the Permotriassic Trappean Complex of Siberia (Ilimpeya River and Kapchan locality) are studied. The water-lava and water-tuff boundaries are shown to be promising for bacterial paleontological studies. The analysis of fossilized microbial communities shows that they vary depending ...

The siliciclastic basal Gulcheru Formation (∼1.8Ga old) of the Proterozoic Cuddapah basin preserves a plethora of mat-induced sedimentary structures like Old Elephant Skin, Wrinkle structure, Kinneyia ripples, Palimpsest ripples etc. in the vicinity of Pullivendla town (Kottalu village), And...
Electrospinning and Characterization of Highly Sulfonated Polystyrene Fibers
Nanofibers of highly sulfonated (IEC ~ 4.5 meq/g) polystyrene (SPS) were successfully electrospun. To accomplish this, the process of electrospinning this difficult-to-spin material was studied in detail. Fiber quality was optimized by manipulating the process and solution variables to fabricate ...
