Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms. Hand washing...

This article describes a simple method to fabricate vertically aligned carbon nanotube arrays by CVD and to subsequently tune their wetting properties by exposing them to vacuum annealing or dry oxidation treatment.
FAQs
Thorough wetting allows liquid resin to contact the surfaces of successive reinforcement layers. This contact supports formation of a fiber-reinforced structure rather than leaving dry regions within the laminate. Operators therefore use brushes or rollers while positioning each layer, and the quality of this impregnation depends on consistent handling and resin-to-fiber distribution.
Consolidation compresses the laminate during fabrication to remove trapped air and encourage resin to spread through the reinforcement. This step matters because incomplete air removal or uneven impregnation can undermine consistency across the finished structure. Careful consolidation is therefore a central process-control concern in engineering production.
Quality depends strongly on operator skill, resin-to-fiber distribution, layer positioning, and the effectiveness of consolidation. These variables influence whether the reinforcement is thoroughly impregnated and whether the laminate remains consistent from one area to another. Consequently, repeatable handling and controlled application are important when product quality must be reliable.
Fabrication begins by placing dry reinforcement fabrics in a mold. Operators then position successive layers and apply liquid resin with brushes or rollers. They consolidate the laminate to remove trapped air and promote thorough wetting, after which the resin cures into the completed fiber-reinforced structure.
The method can use glass, carbon, or natural fibers as reinforcement materials, together with liquid resin and a mold. Brushes or rollers support manual resin application and consolidation, so specialized automated equipment is not required. This equipment profile supports prototypes, custom components, repairs, and low-volume structures.
Wet hand lay-up is particularly useful for prototypes, custom components, repairs, and low-volume structures. It allows engineers to produce parts without specialized automated equipment, which suits applications where manual fabrication and adaptable part production are acceptable. However, quality can vary with operator skill and process control, so consistent resin-to-fiber distribution remains important.
