The preparing and processing of dried blood spots (DBS) for their final analysis are still poorly standardized for most diagnostic applications. To overcome this shortcoming, a comprehensive step-by-step protocol is suggested and subsequently evaluated with regard to its effectiveness for detecting markers of viral infections.

An integrated system for targeted next-generation sequencing of oncology specimens is described. This cross-platform system is optimized for low-quality and low-quantity tumor biopsies, accommodates low DNA inputs, includes well-characterized multi-variant controls, and features a novel variant caller that is informed by quantitative pre-analytical quality control measures.

Dry Friction

2023
Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible. To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...

Drying Shrinkage

2024
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage. A portion of this drying shrinkage can be reversed; if the concrete is...
FAQs
These mechanisms alter materials through different forms of input: heating changes a material by thermal energy, mechanical action applies physical force, pressure changes the processing environment, and gas-phase reactions enable treatment without an aqueous medium. Engineers select among them according to the desired material change and the form of material being handled.
Removing liquids can reduce several downstream requirements. A process that does not create a wet material stream may need less drying, consume fewer solvents, generate less wastewater, and involve fewer processing steps. These changes can improve process efficiency and resource conservation, especially when production systems must limit liquid handling and associated treatment.
Compared with approaches that rely on liquid solvents or aqueous media, dry processing shifts the central engineering challenge toward heat, force, pressure, gas-phase chemistry, or powder control. The comparison is therefore not simply about substituting one material; it concerns how the desired treatment or separation is achieved and how many subsequent steps are required.
The first decision is the desired change: treatment, manufacturing, or separation. Engineers can then match that objective with heating, mechanical action, pressure, a gas-phase reaction, or controlled handling of powders and other dry materials. This alignment helps define the processing route while avoiding liquid-based steps that may add drying or wastewater requirements.
Its application range includes powder processing, materials fabrication, surface treatment, and semiconductor manufacturing. In each setting, the value of the approach depends on using an appropriate dry mechanism to produce the required material change. These examples show that dry processing is relevant across material operations and advanced manufacturing systems.
Engineers can assess more than whether the target material change occurs. They can also consider solvent consumption, wastewater generation, drying requirements, and the number of processing steps. These measures connect technical performance with resource conservation and production efficiency, helping explain why dry methods remain important in the development of advanced manufacturing systems.
