This study predicts the thermoelectric figure of merit (ZT) for defective gamma-graphyne nanoribbons (γ-GYNRs) using binary coding, convolutional neural networks (CNN), long short-term memory networks (LSTM), and multi-scale feature fusion. The approach accurately predicts ZT values with only 500 initial structures (3% of 16,512 candidates), achieving an R above 0.91 and a mean absolute error (MAE) of 0.

However, only a few 2D anion-rich "sandwich" materials have been experimentally discovered and fabricated, as they are vastly limited by their conventional stoichiometric ratios and structural stability under ambient conditions. Here, we report a 2D anion-rich NaCl crystal with sandwiched structure confined within graphene oxide membranes with positive surface potential.

This study aimed to map transition readiness assessment tools for adolescents with inflammatory bowel disease and determine their suitability.
Methods: A literature review following the Arksey and O'Malley scoping review methodology was conducted.
A Tm(III)-rich silicotungstate Na{Tm(HO)[Tm(HO)(SiWO)]}·35HO () based on the open Wells-Dawson-type [SiWO] building unit was synthesized by the reaction of Na[α-SiWO]·18HO, itaconic acid, and TmCl in a HAc/NaAc buffer solution. Five kinds of Tm(III) ions were found in this compound and further linked the {TmSiW} subunit to form an interesting wavy 1D chain structure, which achieved the introduction of more lanthanide (Ln) ions into the [SiWO] unit for the first time. contains multiple exposed Tm-metal active sites, making it an efficient catalyst for the acetalization of 2-aminobenzamides/2-aminobenzenesulphonamides with aldehydes.
View Article and Find Full Text PDFFrequency-modulated continuous-wave (FMCW) radar is used to extract range and velocity information from the beat signal. However, the traditional joint range-velocity estimation algorithms often experience significant performances degradation under low signal-to-noise ratio (SNR) conditions. To address this issue, this paper proposes a novel approach utilizing the complementary ensemble empirical mode decomposition (CEEMD) combined with singular value decomposition (SVD) to reconstruct the beat signal prior to applying the FFT-Root-MUSIC algorithm for joint range and velocity estimation.
