Modification of the Surface Topography and Composition of Ultrafine and Coarse Grained Titanium by Chemical Etching

open access: yesNanomaterials, 2017
In this study, we present the detailed investigation of the influence of the etching medium (acidic or basic Piranha solutions) and the etching time on the morphology and surface relief of ultrafine grained (UFG) and coarse grained (CG) titanium.

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

open access: yesAI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Development of Polysulfone Hollow Fiber Porous Supports for High Flux Composite Membranes: Air Plasma and Piranha Etching

open access: yesFibers, 2017
For the development of high efficiency porous supports for composite membrane preparation, polysulfone (PSf) hollow fiber membranes (outer diameter 1.57 mm, inner diameter 1.12 mm) were modified by air plasma using the low temperature plasma treatment ...

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

open access: yesAdvanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

open access: yesAngewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Pearl's causality for integrating ecological datasets: A case study on Myricaria germanica in northern Italy

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

open access: yesThe Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
