Here, we present an optimized methodology for producing mycelium-based composites (MBCs) from petrochemicals and polluting materials for thermal insulation applications. To become carbon-neutral and sustainable, biobased and compostable materials like mycelium bio-composite could be the solution. To determine if they meet the construction standards, several experiments were conducted.

Determination of Moisture Content in Soil

Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Bradley Schmitz Soils normally contain a finite amount of water, which can be expressed as the “soil moisture content.” This moisture exists within the pore spaces in between soil aggregates (inter-aggregate pore space) and within soil aggregates (intra-aggregate pore space) (Figure 1). Normally this pore space is occupied by air and/or water. If all the pores are occupied by air, the...

Moisture Content and Bulking of Aggregate

The moisture content of aggregates is a crucial factor in construction, particularly in concrete mixing, as it influences the total water required in the mix. Moisture content represents the water coated on the exterior surface of the aggregate existing in a saturated and surface-dry condition. The total water content of a moist aggregate is the sum of its moisture content and water absorption. When aggregates are exposed to rain or sit in stockpiles, they absorb moisture, which must be...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Wood is a ubiquitous material that has been used in construction from the earliest times. Wood is a renewable, sustainable material with great aesthetic value. Today, there are probably more buildings constructed with wood than any other structural material. Many of these buildings are singlefamily residences, but many larger apartment buildings, as well as commercial and industrial buildings,...
FAQs
The oxygen portion of Oxygen Moisture Testing distinguishes measurement methods by signal generation: electrochemical approaches monitor oxygen reduction, whereas optical approaches use oxygen-dependent quenching. These mechanisms provide different analytical routes for the same target and can be applied to gases, liquids, materials, or sealed packages. The choice therefore depends on the sample context and the measurement approach available.
Moisture measurement can rely on chemically specific water reactions, exemplified by Karl Fischer titration, or on changes in mass and sensor response. These approaches do not represent the same measurement principle: one uses a water-specific reaction, while the others infer moisture from a physical or instrumental response. That distinction helps align the method with the material being examined.
The two analytes can influence chemical stability through different pathways. Oxygen is relevant to oxidation, while water is associated with hydrolysis; both also contribute to concerns such as corrosion, contamination, storage conditions, and shelf life. Considering them together can provide a more complete basis for judging product quality than focusing on only one component.
Results can reveal contamination, indicate whether storage conditions have been maintained, and help assess product quality. In a sealed package, measurements can also support packaging evaluation by showing the conditions surrounding a sensitive material. The analytical result is therefore useful not only as a number, but as evidence for stability and performance decisions.
A practical workflow begins by identifying whether the sample is a material, gas, liquid, or sealed package, then selecting an oxygen or moisture approach suited to that target. Oxygen may be assessed through electrochemical reduction or optical quenching, while moisture may be evaluated by Karl Fischer titration, mass change, or sensor response. Results are then interpreted for quality and stability.
It supports quality control and packaging evaluation when oxygen or water could affect a product. The same measurements are relevant to pharmaceutical and food testing, where contamination, storage conditions, chemical stability, and shelf life matter. They can also guide efforts to improve the stability and performance of sensitive materials.
In chemistry, combined oxygen and moisture measurements help connect analytical observations with processes such as oxidation, hydrolysis, and corrosion. They can support studies of why materials lose stability or performance over time and help evaluate whether packaging or storage conditions contribute. This makes the measurements useful in both applied testing and investigations of chemical behavior.
