Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Identification of yeasts present in artisanal yoghurt and traditionally fermented milks consumed in the northern part of Cameroon [PDF]

open access: yes, 2019
Bacteria generally ferment milk but, sometimes, yeasts are found in fermented milks. The presence of these yeasts in the microbial community of some fermented milks could be intentional or accidental.

Rational Design of Weakly‐Solvating Molecules for Salt‐In‐Pre‐Ionic‐Liquid Electrolytes for Li Metal Batteries

open access: yesAdvanced Science, EarlyView.
The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Challenges and enablers in fluidization technology

open access: yesAIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Research of total-focusing-imaging based on phase coherence and dB amplitude enhancement

open access: yesAIP Advances
To address the issue of weak defect visualization in the ultrasonic total-focusing method (TFM) after denoising, this paper integrates Phase Coherence Imaging (PCI) and dB amplitude enhancement (dB) with the TFM.

Design of a low profile array transducer in d15 mode for high angled shear wave generation [PDF]

open access: yes, 2016
Shear wave inspection is generated from mode conversion of longitudinal waves, using a selected, angled wedge positioned between the transducer and the test specimen.

Effect of aesthetic crown lengthening on life quality and self‐esteem: 2‐year study

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background A gummy smile can result from several factors, often leading to a disharmonious appearance and causing physical and psychological discomfort for the patient. This study aimed to evaluate changes in self‐esteem and quality of life for patients, as well as the recidivism rate, following aesthetic crown lengthening (ACL) surgery ...

Sparse-TFM Imaging of Lamb Waves for the Near-Distance Defects in Plate-Like Structures

open access: yesMetals, 2019
The ultrasonic phased array total focusing method (TFM) has the advantages of high imaging resolution and high sensitivity to small defects. However, it has a long imaging time and cannot realize near-distance defect imaging, which limits its application
