Source: Andrew Duffy, PhD, Department of Physics, Boston University, Boston, MA This experiment duplicates J.J. Thomson's famous experiment at the end of the 19th century, in which he measured the charge-to-mass ratio of the electron. In combination with Robert A. Millikan's oil-drop experiment a few years later that produced a value for the charge of the electron, the experiments enabled scientists to find, for the first time, both the mass and the charge of the electron, which are key...

The advent of site-specific recombinase (SSR) technology and the Cre/lox system has led to numerous advances in molecular biology, and has proven itself as a valuable tool for assessing gene function in transgenic animals. This interview discusses the mechanism of site specific recombination by Cyclization recombinase (Cre) and how the use of this enzyme has led to the development of conditional mutagenesis, which has significant advantages over traditional knock out strategies.
FAQs
Electrical resistance in the conductive die rapidly raises the processing temperature, while mechanical pressure brings powder particles into closer contact. This combined action promotes particle rearrangement, contact formation, and diffusion. Because heat and pressure act together, the material can densify efficiently within shorter dwell times and at temperatures that may be lower than those used in conventional sintering.
The accelerated heating and shortened dwell period reduce the time available for grains to grow during consolidation. At the same time, pressure supports densification and particle bonding. This combination can produce dense materials while limiting excessive grain growth, which helps researchers develop components with controlled microstructures rather than relying only on prolonged high-temperature exposure.
Electrical current, resistance heating, applied pressure, processing temperature, and dwell time all influence the final result. Current and die conductivity govern rapid heat generation, while pressure affects particle rearrangement and contact formation. Temperature and dwell time control how far diffusion and densification proceed, so their combination must be managed to obtain the intended density and microstructure.
A typical workflow places the selected powder into a conductive die, applies mechanical pressure, and passes electrical current through the tooling to generate rapid resistance heating. The temperature and pressure are then maintained for a controlled dwell period so particles can rearrange, form contacts, and diffuse. This sequence produces a consolidated body, often in a near-net-shape form.
The process supports consolidation of ceramics, metals, composites, and other advanced materials. Its ability to produce dense bodies with controlled microstructures and near-net-shape forms makes it relevant to engineering development in energy, aerospace, and electronics. It can also support broader advanced-material manufacturing where rapid processing and tailored consolidation are important.
Engineers can assess density, microstructural control, grain growth, and the degree to which the part approaches its intended shape. The method is particularly valuable when rapid consolidation, reduced thermal exposure, or near-net-shape manufacturing is desirable. These outcomes help determine whether a material is suitable for demanding components in energy, aerospace, electronics, or other engineering systems.
