SCALe‐invariant Integral Surfaces [PDF]

Computer Graphics Forum, 2013
AbstractExtraction of skeletons from solid shapes has attracted quite a lot of attention, but less attention was paid so far to the reverse operation: generating smooth surfaces from skeletons and local radius information. Convolution surfaces, i.e. implicit surfaces generated by integrating a smoothing kernel along a skeleton, were developed to do so.

Surface oxygen vacancy trigger chlorite activation with BiOI for sulfamethoxazole degradation

Journal of Industrial Safety
A UV-induced modification method was employed to introduce photoexcited oxygen vacancies (OV-BiOI) into BiOI, creating a multiphase catalyst that effectively catalyzes chlorite to yield chlorine dioxide (ClO2), the primary reactive oxygen species (ROS ...

A Machine Learning Perspective to the Investigation of Surface Integrity of Al/SiC/Gr Composite on EDM

Journal of Manufacturing and Materials Processing, 2023
Conventional mechanical machining of composite is a challenging task, and thus, electric discharge machining (EDM) was used for the processing of the developed material.

Nano-scale analysis of titanium dioxide fingerprint-development powders [PDF]

, 2008
Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide is suspended in a surfactant and used in the form of a small particle reagent ...

Construction and regulation of high active sites in montmorillonite composite catalyst for the removal of ofloxacin via persulfate activation

Heliyon
In this study, ionic liquids (ILs) were used as organic modifiers by introducing montmorillonite nanolayers containing potential C and N active sites between the montmorillonite nanolayers.

Characterisation of the relationship between surface texture and surface integrity of superalloy components machined by grinding [PDF]

, 2013
The surface texture of a machined component is influenced largely by the processing parameters used during machining and hence, there is a relationship between both the formation of the surface texture and surface integrity of the machined component.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
