The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

The Past and Future of Occupational Exposure Limits [PDF]

Journal of Occupational and Environmental Hygiene, 2015
The development of Occupational Exposure Limits (OELs) is thought to have begun with reports published in 1883 by Max Gruber, a German scientist who studied the effects of carbon monoxide at varying air concentrations by exposing both himself and laboratory animals.( 1 , 2 ) His conclusions reflected the relative imprecision of then available ...

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

Advanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Changes in hygiene standards for lead in the context of indoor shooting range workers exposure

Medycyna Pracy
A significant increase in the number of indoor shooting ranges for many years in Poland and most European countries is connected with a raising number of people potentially exposed to lead (both employees and users).

Enhanced Scintillation with Uncorrelated TL and OSL Signals in LiCaAlF6:Eu Nanoparticles Enables Unprecedented Multimodal Radiation Dosimetry

Advanced Optical Materials, EarlyView.
The graphical abstract illustrates the coexistence of independent OSL and TL signals, demonstrating that the material preserves TL information even after complete OSL zeroing, enabling a dual dosimetric readout within the same material. Abstract The development of multimodal dosimeters capable of preserving independent luminescent signals is a ...

Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...
