Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Enhanced Surface Properties of Biochar Using Activation Strategies for Sustainable Dye Removal: A Review

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water pollution due to hazardous dyes is a severe issue that requires investigation through sustainable and cost‐effective approaches. In the current scenario, biochar, a carbon‐rich material derived from biomass, has found significant importance as an alternative to traditional adsorbents like activated carbon.

Evaluation of the Influence of Antifoam Formulations on Asphaltene Aggregates Using AFM and SEM‐EDS

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Asphaltenes, naturally occurring surfactants in crude oil play a pivotal role in stabilizing oily foams during primary oil processing. Accordingly, understanding how antifoam formulations influence asphaltene aggregation is essential. This study investigates the effect of polydimethylsiloxane (PDMS) with varying molar masses on asphaltene ...

Impact of Limonene Dioxide Incorporation Into DGEBA Epoxy Resins: Effect on Thermal, Rheological, Mechanical, and Dynamic Mechanical Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Scheme illustrating the evolution of mechanical, thermal, and rheological properties from the 100% LDO sample to the 100% DGEBA resin sample across six studied compositions with varying LDO:DGEBA ratios. ABSTRACT This study investigates the incorporation of limonene dioxide (LDO), a bio‐based epoxide, into bisphenol A diglycidyl ether (DGEBA) epoxy ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

open access: yesThe Anatomical Record, EarlyView.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.
