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

Advanced 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

RELATIONSHIP BETWEEN ROLLING AND SLIP RESISTANCE IN ROLLING BEARINGS

Science and Transport Progress, 2016
Purpose. About one of the causes of slip rolling is known from the second half of the 19th century, it was believed that the slip resistance appears at the place of contact due to different speeds on the arc of contact. Only in the mid-20th century it was proved that this resistance is negligible in rolling resistance. However (for some unknown reason)

An All‐Textile, Mechano‐Capacitive Subtle Movement Sensor

Advanced Functional Materials, EarlyView.
A robust all‐textile capacitive sensor is introduced for measuring subtle body movements without long‐term degradation. By separating mechanical deformation from electrical sensing elements, accuracy, responsiveness, and durability are improved. Simple fabrication methods are presented, electrode effects are analyzed, and performance is validated ...

Lubrication life of cylindrical roller bearings for traction motors of railway vehicles (Effects of bearing temperature, vibration acceleration, and grease mass)

Nihon Kikai Gakkai ronbunshu
In general, the life of a rolling bearing is calculated as the total number of rotations until rolling fatigue occurs on the raceway. However, when rolling bearings are used under light loads and high rotational speeds, they are damaged not by rolling ...

Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging

Advanced Functional Materials, EarlyView.
Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...
