Phase Topology Stability of an Optical Vortex via an Electrically Controlled Twist‐Planar Oriented Liquid Crystal Fresnel Lens

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Carbothermic reduction of Electric Arc Furnace Dust via thermogravimetry

REM: International Engineering Journal
Electric Arc Furnace Dust (EAFD) is a solid waste originated from electric steelmaking furnaces. Currently, according to some authors, there is an estimated generation of 15 to 25 kg of dust per ton of steel produced. The formation of the dust is related

Biomimetic Adaptive Hydrothermal Balance Fabric‐Based Dual‐Interface Solar Evaporator for Efficient and Stable Desalination

Advanced Science, Volume 13, Issue 10, 18 February 2026.
This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...

Coupled Experimental Study and Thermodynamic Modeling of GeO2 and GeO2–CaO and GeO2–SiO2 Binary Systems

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...

Review of Flash Joule Heating for the Synthesis of Graphene and Other Functional Carbon Materials

Carbon Energy, Volume 8, Issue 1, January 2026.
ABSTRACT Flash Joule heating (FJH), as a high‐efficiency and low‐energy consumption technology for advanced materials synthesis, has shown significant potential in the synthesis of graphene and other functional carbon materials. Based on the Joule effect, the solid carbon sources can be rapidly heated to ultra‐high temperatures (> 3000 K) through ...
