Imprinting

2019
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting. Survival Mother sheep imprint onto the scent of their lambs within...

Genomic Imprinting and Inheritance

2020
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes. The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

We present a unique platform for characterizing electrode surfaces in solid oxide fuel cells (SOFCs) that allows simultaneous performance of multiple characterization techniques (e.g. in situ Raman spectroscopy and scanning probe microscopy alongside electrochemical measurements). Complementary information from these analyses may help to advance toward a more profound understanding of electrode reaction and degradation mechanisms, providing insights into rational design of better materials for...

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds. To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
FAQs
Pressure brings the patterned mold or stamp into contact with the silicon, while temperature helps control how the surface responds during imprinting. These conditions determine whether channels, cavities, and other features reproduce the mold geometry consistently. Careful control is therefore important for achieving the intended microscale or nanoscale dimensions and for maintaining repeatability across fabricated structures.
Imprinting transfers surface features, but selective etching or material removal further defines the desired silicon geometry. This follow-up step can clarify channels, cavities, or other recessed structures according to the transferred pattern. The combination of mechanical pattern transfer and controlled removal gives engineers greater control over the final shape, which directly influences device performance and reliability.
Solid Silicon Mac-imprint forms patterns by pressing a structured mold or stamp into bulk silicon and then using selective material removal, rather than relying entirely on conventional lithographic patterning. This can reduce dependence on lithographic steps while preserving high-resolution feature formation. Its repeatable pattern transfer also supports engineering goals involving scalable fabrication of microsystems and semiconductor structures.
The method can create repeatable channels, cavities, and other high-resolution surface features in solid silicon. These geometries are not merely decorative: their dimensions and arrangement determine how components function in sensors, microelectronics, microsystems, and optical devices. Selecting a suitable mold pattern allows the fabrication approach to be adapted to the structural requirements of a particular device.
A typical workflow begins with a patterned mold or stamp positioned against bulk silicon. Controlled pressure and temperature transfer the surface pattern into the material, after which selective etching or another material-removal step defines the intended structures. The resulting silicon geometry can then serve as the functional or structural basis for a microscale or nanoscale engineered component.
Engineers may choose Solid Silicon Mac-imprint when a design requires repeatable microscale or nanoscale silicon geometry and reduced reliance on conventional lithographic patterning. It is relevant to microelectromechanical systems, semiconductor devices, optical components, and integrated sensors. The approach is especially valuable when channels, cavities, or other precisely defined features affect performance, reliability, or manufacturing scalability.
