Unsupervised quality monitoring of metal additive manufacturing using Bayesian adaptive resonance.

Metal additive manufacturing is a recent breakthrough technology that promises automated production of complex geometric shapes at low operating costs. However, its potential is not yet fully exploited due to the low reproducibility of quality in mass production. The monitoring of parts quality directly during manufacturing promises to solve this problem, while machine learning showed efficient performance correlating versatile manufacturing measurements with different quality grades.

New genera and new species of Catenulaceae (Bacillariophyta) from Coral Reef habitat of two Indonesia islands-Bawean and Sulawesi-A morphological approach.

Indonesia is listed as a region with high marine biodiversity, especially when considering the three large tropical ecosystems: seagrass beds, mangroves and coral reefs. It is likely that the biodiversity of diatoms in this area is also high. Samples for this research were taken from the remote area of Bawean Island and Tomini Gulf in Central Sulawesi.

Application of TiO Supported on Nickel Foam for Limitation of NO in the Air via Photocatalytic Processes.

TiO was loaded on the porous nickel foam from the suspended ethanol solution and used for the photocatalytic removal of NO. Such prepared material was heat-treated at various temperatures (400-600 °C) to increase the adhesion of TiO with the support. Obtained TiO/nickel foam samples were characterized by XRD, UV-Vis/DR, FTIR, XPS, AFM, SEM, and nitrogen adsorption at 77 K.

The Impact of N/O-Functional Groups on the Sorption Capabilities of Activated Carbons Derived from Furfuryl Alcohol.

This work describes the effect of nitrogen and oxygen functional groups on the sorption properties of activated carbons produced from furfuryl alcohol. The poly(furfuryl) alcohol underwent carbonization in nitrogen, ammonia, and ammonia and air (in a 3:2 proportion) atmospheres at 600 °C for 4 h. The resulting materials were subsequently activated in a carbon dioxide atmosphere for 1 h at temperatures of 700 °C, 800 °C, 900 °C, and 1000 °C.

The Superiority of TiO Supported on Nickel Foam over Ni-Doped TiO in the Photothermal Decomposition of Acetaldehyde.

Acetaldehyde decomposition was performed under heating at a temperature range of 25-125 °C and UV irradiation on TiO doped by metallic Ni powder and TiO supported on nickel foam. The process was carried out in a high-temperature reaction chamber, "The Praying Mantis", with simultaneous in situ FTIR measurements and UV irradiation. Ni powder was added to TiO in the quantity of 0.
