DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption
Advanced Functional Materials, EarlyView.The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Face-seal lubrication. 2: Theory of response to angular misalignement [PDF]
A theoretical analysis was made of a hypothetical seal operating mode. The hypothetical seal model provides for three degrees of primary ring motion and includes the force and moments induced by primary ring response to seat angular misalignment.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Thermal stress analysis of ceramic gas-path seal components for aircraft turbines [PDF]
Stress and temperature distributions were evaluated numerically for a blade-tip seal system proposed for gas turbine applications. The seal consists of an abradable ceramic layer on metallic backing with intermediate layers between the ceramic layer and ...

Modified face seal for positive film stiffness [PDF]
, 1981 The film stiffness of a face seal is improved without increasing the sealing and dam area by using an apparatus which includes a primary seal ring in the form of a nose piece. A spring forces a sealing surface on the seal ring into sealing contact with a

Nature‐Inspired Sustainable Cooling for Photovoltaics with Enhanced Temperature‐Salinity Dynamics
Advanced Functional Materials, EarlyView.Addressing solar panel overheating, a nature‐inspired cooling system mimicking ocean currents is developed. A moisture‐absorbing solution layer uses sunlight, radiative cooling, and moisture processes to create temperature/salinity gradients, accelerating circulation. The prototype cools panels by up to 18.2 °C under sunlight, sustains cooling, rapidly

Self-acting geometry for noncontact seals [PDF]
Performance ot two self acting seal designs for a liquid oxygen (LOX) turbopump was predicted over ranges of pressure differential and speed. Predictions were compared with test results. Performance of a radial face seal for LOX was predicted up to 448 N/
