Probe Tips or Probe Needles come in a variety of materials, lengths, shapes and tip diameter or radii (Everbeing are stated in tip diameter). They provide direct electrical contact to the circuit under test. Probe tips are specified to suit each individual application. Considerations should be made regarding the material to be probed, temperature, bond pad size and bond pad...

Achieving atomic-resolution microscopy of Al-Cu thin films on electron-transparent silicon nitride TEM grids is hindered by the limitations of conventional preparation techniques. Dimpling, grinding, and standard ion milling are incompatible with the grid's fragile and stressed silicon nitride window. Additionally, the focused ion beam (FIB) lift-out technique risks rupturing the stressed windows, which can cause specimen loss. Ga contamination during FIB...

Sample preparation techniques for large-area data acquisition Large-area transmission Kikuchi diffraction (TKD) analysis of nanostructured nickel. Inverse pole figure (IPF) color-coded orientation maps with 8 nm twin boundaries are shown. Data was collected from defect-free, ultrathin ~40 nm samples with a maximum of three grain layers. TKD analyses condition: 30 kV acceleration voltage and 1.6 nA beam current. To achieve optimal...

Continuous monitoring of tissue microphysiology is a key enabling feature of the organ-on-chip (OoC) approach for drug screening and disease modeling. Sensing charged species in OoC tissue microenvironments is thereby essential. However, the inherently small (i.e., cm) size of OoC devices poses the challenging requirement to integrate miniaturized and highly sensitive in situ charge sensing components to maximize signal extraction...

The ability to tune the localised surface plasmon resonance (LSPR) behaviour of metal nanostructures has great importance for many optical sensor applications such as metal (plasmon) enhanced fluorescence spectroscopy and surface-enhanced Raman scattering (SERS). In this paper, we used Aerosol Direct Writing (ADW) to selectively deposit fine gold nanoparticles (AuNPs) patterns. A low-temperature thermal post-treatment (below 200 °C) provides enough...

The growing diversity in the used materials in semiconductor packaging provides challenges for achieving good interconnection. Particularly the very soft substrates, such as paper and polymers, and very hard, such as silicon carbide, offer unique challenges to wire-bonding or formation of vertical interconnects. Complementary technologies are therefore needed. Here, a method to direct-write metal tracks on the top and sides...

Poly(3,4-ethylenedioxy thiophene):poly(styrenesulfonate) (PEDOT:PSS) exhibits valuable characteristics concerning stability, green-processing, flexibility, high electrical conductivity, and ease of property modulation, qualifying it as one of the most promising p-type organic conductors for thermoelectric (TE) applications. While blending with inorganic counterparts is considered a good strategy to further improve polymeric TE properties, only a few attempts succeed so far due to inhomogeneous embedding...

Some fundamental concepts of catalysis are not fully explained but are of paramount importance for the development of improved catalysts. An example is the concept of structure-insensitive reactions, where surface-normalized activity does not change with catalyst metal particle size. Here we explore this concept and its relation to surface reconstruction on a set of silica-supported Ni metal nanoparticles (mean particle...
