Mesoporous silica exhibits a diverse range of applications owing to its pore structure and inter-pore correlation. Consequently, quantitative characterization of its mesoscopic structure is extremely crucial to reciprocate its potential applications. In this work, we utilized the chemical and aerosol routes to successfully synthesize granular, porous silica with an average pore size in the range of ∼5-10 nm and different degrees of structural correlation among its pores.

This study reports on the development of a highly sensitive non-enzymatic electrochemical sensor based on a two-dimensional TiCT/MWCNT-OH nanocomposite for the detection of paraoxon-based pesticide. The synergistic effect between the TiCT nanosheet and the functionalized multi-walled carbon nanotubes enhanced the sensor's conductivity and catalytic activity. The nanocomposite demonstrates superior electrochemical and electroanalytical performance compared to the pristine TiCT and MWCNT-OH in detecting paraoxon-ethyl in fruit samples (green and red grapes), with a linear response range from 0.

Department of Special Education, Central China Normal University, Wuhan.
Purpose: This cross-sectional study explored how the speechreading ability of adults with hearing impairment (HI) in China would affect their perception of the four Mandarin Chinese lexical tones: high (Tone 1), rising (Tone 2), falling-rising (Tone 3), and falling (Tone 4). We predicted that higher speechreading ability would result in better tone performance and that accuracy would vary among individual tones.
Method: A total of 136 young adults with HI (ages 18-25 years) in China participated in the study and completed Chinese speechreading and tone awareness tests.
Quantifying Tinnitus Perception Improvement: Deriving the Minimal Clinically Important Difference of the Minimum Masking Level.
J Speech Lang Hear Res

Division of Speech Pathology and Audiology, Research Institute of Audiology and Speech Pathology, College of Natural Sciences, Hallym University, Chuncheon, South Korea.
Purpose: Tools that can reliably measure changes in the perception of tinnitus following interventions are lacking. The minimum masking level, defined as the lowest level at which tinnitus is completely masked, is a candidate for quantifying changes in tinnitus perception. In this study, we aimed to determine minimal clinically important differences for minimum masking level.

Micro- and nanomorphological modification and roughening of titanium implant surfaces can enhance osseointegration; however, the optimal morphology remains unclear. Laser processing of implant surfaces has demonstrated significant potential due to its precision, controllability, and environmental friendliness. Femtosecond lasers, through precise optimization of processing parameters, can modify the surface of any solid material to generate micro- and nanomorphologies of varying scales and roughness.
