A Universal van der Waals Tunneling Injector for Monolayer CMOS

Advanced Materials, EarlyView.
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Carbon dioxide gas sensor based on self-assembled WGM microbottle resonator coated with polymethyl methacrylate [PDF]

In this study, researchers looked into how coating MBRs with polymethyl methacrylate (PMMA) affected their performance as a carbon dioxide gas sensor. Using a "soften-and-compress" technique, SMF28 produced the MBR shape, which was then coated in a PMMA ...

Surface Adherence of Candida albicans to Different Polymethyl Methacrylate Resin Denture Base Materials

, 2011
Over the years researchers have reported on the frequency and distribution of yeast in the oropharynx of apparently normal individuals and those with systemic or mycotic diseases wearing dentures. Few workers have taken into consideration the role played

A Single‐Solvent Acetone Strategy for Surface Enhancement and Robust Bonding in PMMA Microfluidic Devices

Advanced Materials Interfaces, EarlyView.
A single‐solvent acetone strategy simultaneously restores laser‐ablated PMMA surfaces and enables high‐strength bonding for microfluidic device fabrication. The process produces smooth, optically clear channels, achieves bonding strengths up to 27.3 MPa, and forms leak‐free devices within 25 min, providing a rapid and accessible route to robust PMMA ...

A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

Electrically Reconfigurable Optical Initialization of Spin Valley Polarization in Monolayer WS2 Enabled by Switchable Dual‐Mode Liquid Crystal Lasers

Advanced Optical Materials, EarlyView.
This work presents an electrically controllable approach to spin–valley polarization in monolayer WS2 by integrating it with a dual‐mode liquid crystal laser. Applying an external field triggers phase transitions that switch the laser emission between helicity‐defined band‐edge lasing and unpolarized random lasing.
