Controlling Sub–100-nm Particulate and Ultrathin Residue Defects Most people don’t think it is possible to chemically identify molecules at the nanoscale. However, IR PiFM from Molecular Vista, Inc. has the sensitivity and spatial resolution required to name the compound of sub–100-nm defects and directly visualize monolayers based on their molecular vibrations.

Do you have tools that will allow you to chemically identify a 15 nm organic particle on a Silicon wafer or mask without touching it? Join Molecular Vista's webinar tomorrow to learn how it's done using Photo induced Force Microscopy (PiFM).

How pure should a High Purity Germanium Crystal be ? The purity of High Purity Germanium (HPGe) crystals typically needs to be on the order of 13N purity, which means 99.99999999999% pure, with impurity levels less than 1 part per trillion (ppt). This extreme purity is essential for reducing free charge carriers in the crystal, allowing it to function effectively as a semiconductor in applications like gamma-ray and X-ray detectors. The higher the purity, the better the crystal's performance in terms of energy resolution and signal-to-noise ratio, making it suitable for detecting even very low levels of radiation with high precision.

600 MHz that is the size (and has the helium evaporation rate) of a 400 MHz! Check out the new EVO lineup!

Here are compared CoFeB etch profiles using different frequencies in TEM. Check out the results in the image (a) for 13.56 MHz and (b) for 400 kHz. Interestingly, the CoFeB etched with 400 kHz showed a wider bottom gap between features compared to 13.56 MHz. Isn't the frequency dependent etch result interesting? #nanotechnology #research #TEM #materials #semiconductor #CoFeB #etching #technology #RF Source: https://lnkd.in/gDCXUa87

Delighted to share our work on the Regioselective Metalation entitled as "Towards New Coordination Modes of 1,2,3-Triazolylidene: Controlled by the Nature of 1st Metalation in a Heteroditopic Bis-NHC Ligand" in online linkedin #RSCPoster 2024 conference. #RSCInorg #RSCPosterPitch Kindly Check the publication https://lnkd.in/gQ-nyZXC An unusual effect of the nature of first metal coordination of a heteroditopic N-heterocyclic carbene ligand towards the coordination behavior of 1,2,3-tzNHC is explored. The first metal coordination at the ImNHC site (complexes 3 and 4) was noted to substantially influence the electronics of the 1,2,3-triazolium moiety leading to an unprecedented chemistry of this MIC donor. Along this line, the RhIII/IrIII-orthometalation in complexes makes the triazolium C4-H more downfield shifted than C5-H, whereas a reverse trend, although to a lesser extent, is observed in case of the non-chelated PdII-coordination. This difference in behavior assisted us to achieve the selective activation of triazole C4/C5 positions, not observed before, as supported by the isolation of the homo- and hetero-bimetallic complexes, via C5- and C4-metalation, respectively. Further, the %Vbur calculation eliminates any considerable steric influence and the DFT studies strongly support the selectivity observed during bimetalation.

Scientists have created a smart optical material, DACSM, by combining diacetylene and cyanostilbene, enabling multiple molecular states with a single dye. Through photochemical reactions and topochemical polymerization, DACSM can change its molecular state. Thermal and photochemical stimuli further tune its conformation, leading to optical multi-states. These properties enable the creation of switchable optical patterns and smart secret codes.
