Influence of mode of breathing on pharyngeal airway space and dento facial parameters in children: a short clinical study

open access: yesBulletin of the National Research Centre, 2022
Background Mouth breathing is considered as a mode of breathing modality that presents as a replacement to normal nasal breathing. This persistent pattern of mouth breathing have considerable influence on the development of dentofacial structures.

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Portable Breathing Monitoring With Phase‐Resolved Airflow Dynamics Enabled by a Dual‐Response Flexible PZT Sensor

open access: yesAdvanced Healthcare Materials, EarlyView.
A portable respiratory monitoring device based on a flexible PZT sensor captures pressure‐ and temperature‐related airflow responses in a single waveform. Polarity‐opposed piezoelectric and pyroelectric components generate a narrow transient spike and a broad quasi‐steady peak during both inhalation and exhalation. This dual‐component structure enables
