We use an aberration-corrected scanning transmission electron microscope to define single-digit nanometer patterns in two widely-used electron-beam resists: poly (methyl methacrylate) and hydrogen silsesquioxane. Resist patterns can be replicated in target materials of choice with single-digit nanometer fidelity using liftoff, plasma etching, and resist infiltration by organometallics.

A method is described whereby quantum dot (QD) nanoparticles can be used for correlative immunocytochemical studies of epoxy embedded human pathology tissue. We employ commercial antibody fragment conjugated QDs that are visualized by widefield fluorescence light microscopy and transmission electron microscopy.

Electron Affinity

The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion). This process can be either endothermic or exothermic, depending on the element. Many of these elements have negative values of EA, which means that energy is released when the gaseous atom accepts an electron. However, for some elements, energy is required for the atom to become negatively charged, and the value of their EA is positive. Just as with ionization energy,...

Electron Carriers

2019
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons. Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
FAQs
Its tilt sensors respond to the direction of gravitational acceleration rather than relying on a visual bubble position. Onboard electronics interpret that sensor signal and calculate a numerical relationship between the instrument and gravity. The result can be presented as an angle, slope percentage, or height difference, allowing engineers to select the measurement form most useful for a particular alignment or inspection task.
Digital calibration helps establish a consistent measurement reference before readings are used for engineering decisions. Visual indicators provide an immediate numerical or graphical result, while audible indicators can help users recognize a condition without continuously watching the display. Together, these features support repeatable checking of alignment and make it easier to identify whether a surface meets an intended tolerance.
A traditional bubble level mainly shows whether a surface approaches level through the position of a bubble. An Electronic Digital Level adds quantitative output, such as an angle, slope percentage, or height difference. That numerical information supports more precise comparisons, recording, and quality-control decisions, especially when an engineering task requires documented measurements rather than a simple visual judgment.
Place the instrument on the surface or component being evaluated, allow its sensor reading to be displayed, and interpret the result in the unit most appropriate for the task. The user can then compare the value with the required alignment or tolerance and document the measurement. This workflow applies to construction alignment, machinery installation, and inspection activities.
The instrument supports several measurement and verification tasks across engineering practice. Construction teams can check alignment, surveyors can evaluate slope or height-related conditions, and inspectors can assess structural alignment. It also assists with machinery installation and quality control, where numerical readings help confirm that components or surfaces satisfy project requirements and provide a record for later review.
During structural inspection, measured inclination or slope can help engineers evaluate whether a surface or component aligns with the expected condition. In quality control, numerical readings provide evidence that a manufactured, installed, or constructed element falls within the required tolerance. Because results can be documented, the instrument supports both immediate verification and traceable review in field or laboratory work.
