Text Sentiment Analysis of Douban Film Short Comments Based on BERT-CNN-BiLSTM-Att Model

IEEE Access
To solve the problems of polysemy and feature extraction in the text sentiment analysis process, a BERT-CNN-BiLSTM-Att hybrid model has been proposed for text sentiment analysis. The BERT pre-training model was established to break up the text input into

Complementary Logic Driven by Dielectrophoretic Assembly of 2D Semiconductors

Advanced Functional Materials, EarlyView.
Scalable, parallel fabrication of complementary logic gates is demonstrated using electric‐field‐driven deterministic assembly of electrochemically exfoliated 2D n‐type MoS2 and p‐type WSe2 nanosheets. This strategy yields MoS2 and WSe2 transistors featuring average mobilities of 4.3 and 3.0 cm2 V−1 s−1, respectively, and on/off ratios of > 104 ...

Spatially Resolved Click Patterning of Dyes on Graphene for 2D Hybrids with Regiotunable Fluorescence

Advanced Functional Materials, EarlyView.
Well‐structured graphene hybrid architectures featuring spatially resolved fluorescent properties represent a promising but so‐far elusive synthetic target. A robust and straightforward method for fabricating well‐organized graphene‐dye hybrid nanoassemblies through a combination of reductive patterning and conventional click chemistry is presented ...

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Single Solid‐State Ion Channels as Potentiometric Nanosensors

Advanced Functional Materials, EarlyView.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

Optimizing Aspect-Based Sentiment Analysis Using BERT for Comprehensive Analysis of Indonesian Student Feedback

Applied Sciences
Evaluating the learning process requires a platform for students to express feedback and suggestions openly through online reviews. Sentiment analysis is often used to analyze review texts but typically captures only overall sentiment without identifying

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

Advanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...
