Microplastics have polluted our environment, particularly mangrove ecosystems, the barriers between land and sea that trap sediments and pollutants. The abundance of microplastics has increased in microplastic deposition and is expected to rise in the ...

Surface-chemical and -morphological gradients [PDF]
Surface gradients of chemistry or morphology represent powerful tools for the high-throughput investigation of interfacial phenomena in the areas of physics, chemistry, materials science and biology. A wide variety of methods for the fabrication of such gradients has been developed in recent years, relying on principles ranging from diffusion to time ...

Evidence of coastal landforms and age determination related to the sealevel change at Nakhon Si Thammarat province in southern Thailand [PDF]
We present evidence of sea-level changes over the past 15,000 years from dating sandy beach sediments in Nakhon Si Thammarat province. First, we classified various types of coastal landforms from satellite images.

Evidence for intermolecular forces involved in ladybird beetle tarsal setae adhesion
Why can beetles such as the ladybird beetle Coccinella septempunctata walk vertically or upside-down on a smooth glass plane? Intermolecular and/or capillary forces mediated by a secretion fluid on the hairy footpads have commonly been considered the ...

Mini Review: Comparison of Bio-Inspired Adhesive Feet of Climbing Robots on Smooth Vertical Surfaces
Developing climbing robots for smooth vertical surfaces (e.g., glass) is one of the most challenging problems in robotics. Here, the adequate functioning of an adhesive foot is an essential factor for successful locomotion performance.

Morphology and surface reconstructions of GaN(11̄00) surfaces [PDF]
GaN is grown by plasma-assisted molecular-beam epitaxy on ZnO(11̄00) substrates. Well-oriented (11̄00) GaN surfaces are obtained, and (11̄01) oriented facets are also observed. On the GaN(11̄00) surfaces under Ga-rich conditions, a surface reconstruction with approximate symmetry of “4×5” is found.

Impact of Calcium Phosphate Particle Morphology on Osteoconduction: an in vivo study [PDF]
Apatite/β−TCP particles exhibiting non-conventional urchin-like morphology were prepared by hydrothermal synthesis. Their implantation in the rat calvarium was followed during 60 days.

Surface Morphology of GaN: Flat versus Vicinal Surfaces [PDF]
The surface morphology of GaN films grown by molecular beam epitaxy (MBE) is investigated by scanning tunneling microscopy (STM). A comparison is made between flat and vicinal surfaces. The wurtzite structure of GaN leads to special morphological features such as step pairing and triangularly shaped islands.

Surface Morphology Changes of Bleached Dental Ceramics
Tooth whitening is one of the most conservative procedures for increasing the aesthetics of patients, but the effect of bleaching on ceramic restorations has not been extensively studied.

Anisotropic Drop Morphologies on Corrugated Surfaces [PDF]
The spreading of liquid drops on surfaces corrugated with micron-scale parallel grooves is studied both experimentally and numerically. Because of the surface patterning, the typical final drop shape is no longer spherical. The elongation direction can be either parallel or perpendicular to the direction of the grooves, depending on the initial drop ...
