Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Nanomaterials‐Decorated Biomass‐Derived Carbon for Overall Water Splitting: Interfacial Engineering, Mechanistic Insights, and Device Translation

The Chemical Record, EarlyView.
Biomass‐derived carbon provides a sustainable, porous, and conductive scaffold that stabilizes nanomaterials for bifunctional hydrogen evolution reaction/oxygen evolution reaction catalysis. This review summarizes design strategies (defects, heteroatom doping, heterostructures, single atoms), mechanistic/density functional theory insights, degradation ...

Geopolymers as a Sustainable Chemical Platform: From Building Materials to Advanced Functional Applications

The Chemical Record, EarlyView.
Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

[Energy requirements of miners engaged in open-pit coal mining].

Voprosy pitaniia, 1988
It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

Wildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Mineral Oil‐Induced Ageing Characteristics of Aluminium Nitride‐Doped Silicone Rubber Nanocomposites

High Voltage, EarlyView.
ABSTRACT Room temperature vulcanised (RTV) silicone rubber, commonly used as an external insulating coating on ceramic bushings of oil‐immersed transformers, undergoes significant degradation when exposed to mineral oil under harsh environmental conditions.
