Journal ArticleDOI
Carbon Aerogel from Winter Melon for Highly Efficient and Recyclable Oils and Organic Solvents Absorption
TL;DR: In this paper, three-dimensional carbon aerogels were fabricated via a hydrothermal and post-pyrolysis process using winter melon as the only raw materials and showed a low density of 0.048 g/cm3, excellent hydrophobicity with a water contact angle of 135° and selective absorption for organic solvents and oils.
Journal ArticleDOI
Thermal and chemical stability of hexagonal boron nitride (h-BN) nanoplatelets
TL;DR: In this paper, high-temperature properties of boron nitride platelets were systematically evaluated through TGA in combination with differential scanning calorimetry (DSC) X-Ray Diffraction (XRD) studies confirmed the hexagonal graphitic-like structure of the material, while Fourier-Transform Infrared Spectroscopy (FT-IR) indicated the active vibration modes related to the B-N bond.
Journal ArticleDOI
From biomass to high performance solar–thermal and electric–thermal energy conversion and storage materials
TL;DR: In this article, the authors demonstrate that lightweight, highly electrically conductive, and three-dimensional (3D) carbon aerogels (CAs) can be produced via a hydrothermal carbonization and post pyrolysis process using various melons as raw materials.
Journal ArticleDOI
Adaptive VN/Ag nanocomposite coatings with lubricious behavior from 25 to 1000 °C
Samir Aouadi,Dinesh Pratap Singh,D. S. Stone,Kyriaki Polychronopoulou,Farwah Nahif,Claus Rebholz,Claus Rebholz,Christopher Muratore,Andrey A. Voevodin +8 more
TL;DR: In this paper, a two-phase nanocomposite coating that consists of inclusions of silver in a vanadium nitride matrix (VN/Ag) was investigated as a potential adaptive coating with a reduced friction coefficient from 25 to 1000°C.
Journal ArticleDOI
Chalcogenide Aerogels as Sorbents for Radioactive Iodine
Kota S. Subrahmanyam,Debajit Sarma,Christos D. Malliakas,Kyriaki Polychronopoulou,Brian J. Riley,David A. Pierce,Jaehun Chun,Mercouri G. Kanatzidis +7 more
TL;DR: In this article, several sulfidic chalcogels were explored as iodine sorbents including NiMoS4, CoMoS 4, Sb4Sn3S12, Zn2Sn2S6, and K0.16CoSx.
