CESSATION OF RESPIRATORY EXCHANGE

open access: yesAnnals of Surgery, 1941
In observing the artificial state of disturbed function known as anesthesia, the anesthetist has almost constant occasion to study respiratory problems, which in other branches of medicine are encountered so infrequently as to prevent familiarity. It therefore seems to be within the anesthetist's province to offer his views on this subject.

Ultrasound in Women's Health: Mechanisms, Applications, and Emerging Opportunities

open access: yesAdvanced Materials, EarlyView.
As healthcare moves toward decentralization, ultrasound technologies are evolving from strictly imaging tools in clinical settings into versatile diagnostic and therapeutic platforms, with growing roles addressing women's health needs. This review highlights how ultrasound's underlying physical mechanisms can be harnessed to reduce disparities in women'

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Formation of Laser‐Induced Periodic Surface Structures on Titanium Alloy Using a Picosecond Laser: Dependence on Fluence and Number of Laser Pulses

open access: yesAdvanced Materials Interfaces, EarlyView.
Laser treatment of materials is a versatile technique for generating ordered surface structures. Nevertheless, such structures are the result of laser parameters such as laser pulse fluence. We demonstrate that homogeneous low special frequency laser‐induced periodic surface structures are contingent on both single and effective fluence dose and can be

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

open access: yesAdvanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Prevalence And Pattern of Tobacco Use in Rural Community of Jaipur, Rajasthan (India): A Cross Sectional Study

open access: yesNational Journal of Community Medicine, 2015
Introduction: Tobacco use is one of the important preventable causes of death and a leading public health problem all over the world. Tobacco users who die prematurely deprive their families’ from income, education and health care. Now it is appropriate

Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

open access: yesAdvanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.
