Protochips Launches In Situ AX– Machine Vision Powered Solutions for your TEM Applications |
|
|
Protochips is excited to launch In Situ AX, a family of machine-vision powered solutions that addresses the end-to-end challenges of in situ TEM, from sample prep all the way to publication. |
|
|
The latest evolution of AXON Synchronicity and AXON Studio support this approach with powerful new features that greatly improve your experience on the TEM. A new session Notes tab lets your record any relevant information in Studio and tie it to your data. An Attachments tab lets you insert papers, notes, data files or images where it will be the most useful to all users who share the data. Also added is the ability to graph any two pieces of metadata against one another for instant visualizations that help us illuminate and understand correlations. |

Also included in the launch is the new Standard Reference Electrode, which provides a true external reference potential, for results far more comparable to standard bulk chemistry measurements. This new design is incredibly easy to set up and offers flexible electrode material selection and long-term stable potentials. |

Tuesday Publication Update! 📖 In this awesome publication, Joanna Korpanty shows how to use the #PoseidonSelect for liquid cell transmission electron microscopy (LCTEM) to study polymeric nanomaterials in organic solvents. The assembly of poly(styrene)-b-poly(4-vinylpyridine) was followed in N,N-dimethylformamide and methanol. The worm-to-micelle transformation in poly(styrene)-b-poly(4-vinylpyridine) was triggered via organic solvent mixing during LCTEM, enabling an experiment not possible through a cryogenic TEM time series. This work provides a pathway for an expanded examination of nanomaterials in organic solvents via LCTEM, a neglected research area despite the obvious prevalence of such materials across chemistry and materials science.Interested and want to learn more?https://lnkd.in/gWSKM3gFIf you want to see more from Joanna, please watch her Flash Talk on our YouTube account!https://lnkd.in/gMkMP8KJ |

New Tuesday publication! 📖 In this publication featured in Nature, our #PoseidonSelect was used to look at crystals grown from high-energy precursors. Most of the time, these adopt metastable structures depending on the initial conditions, such as temperature, pressure or crystal size. With the unique environment created in the liquid cell, the formation of a hcp phase could be observed in Pd precursor solutions. Using this insight may provide a new route for designing and synthesizing novel energy storage materials.Have you become interested?Read the full publication here:https://lnkd.in/gjGXu6Fq |

Tuesday publication update! 📖 The shape of any nanoparticle also influence their reactivity by exposing different crystal facets. This is why having control over the shape and size is of importance. In this newest publication, the changes of individual surface-exposed facets during diverse shape transformations of Au nanocrystals using liquid phase TEM in various chemical potentials and kinetic Monte Carlo simulations were investigated using our #PoseidonSelect system. The results show that diffusion of surface atoms heavily contribute to the final structure in Au nanocrystal transformation which can in turn help gain control over the synthesis of the size and shape of the particles.Have you become curious?

Additional Friday publication! 📖 The direct observations of nanomaterials growth led by self-propelled droplet transport has not been researched often. This leaves many questions unanswered that can be answered using in-situ microscopy. In this research an indium droplet was observed to migrate on a silicon nitride membrane coated by a layer of hydrogenated amorphous silicon (a-Si:H). This results in the production of a crystalline Si nanowire in its trail. This work directly unveils rich transport mechanism of catalytic droplets, which are expected to be a new platform for producing diverse low-dimensional nanomaterials and promote their potential applications in nanoscience and technologies.Want to read more?https://lnkd.in/dXHaaZSC |

New Tuesday publication update! 📖 Vacancies are defects which are of utmost importance in the thermophysical and structural properties of materials. Higher vacancy concentrations at elevated temperatures lead to an expansion in the sample volume, however, it is not straightforward to experimentally measure their concentration or to visualize them directly. In this newest publication in from the University of Berkeley, the authors have looked at gold films and demonstrate a state-of-the-art nanoscale point defect mapping technique. They used 4D-STEM which provided the ability to measure heterogeneous vacancy or interstitial concentrations.Have you become curious to this work?Read it here!https://lnkd.in/gXYr8fAX |

Tuesday publication update! 📖 Carbon dioxide electroreduction facilitates the sustainable synthesis of fuels and chemicals. To understand more about carbon dioxide reduction, identifying active sites of high-performance Cu nanocatalysts is necessary. In this publication, @Yao Yang, from the university of Berkeley, uses the #PoseidonSelect and 4D-STEM to show the electrochemical reaction with Cu nanoparticles. The correlation of multimodal operando techniques serves as a powerful platform to advance our fundamental understanding of the complex structural evolution of nanocatalysts under electrochemical conditions. The monodisperse Cu NPs undergo structural transformations where the surface oxide is reduced, followed by aggregation.Interested in the paper?Read it here!https://lnkd.in/d5BarD5Y |

Tuesday publication update! 📖 Congratulations to Vesna Srot from the Max Planck Institute on publishing this nice work showing a new methodology for the preparation of focussed ion beam (FIB) lamella for in-situ microscopy. Additionally, they investigated what the influence of the beam was on the electrical and electro-thermal measurements. Furthermore, thinning of the whole lamella or parts of the lamella, as well as forming/cutting different slits into the lamella might influence the electrical characteristics as determined in this new publication, and needs to be carefully considered for each specific case.Curious?https://lnkd.in/g2rc9x67 |

Additional Friday publication update! 📖 In this article, both the #Atmosphere and the #FusionSelect were used to look at catalyst pyrolysis! High temperature treatment in inert atmosphere (pyrolysis) is the essential, most common method for the synthesis of metal-nitrogen-carbon (M-N-C) catalysts and critical to achieve high electrocatalytic activity and electronic conductivity. The multi-analytical technique observations conducted in this paper, provide a base for rational design and optimization of M-N-C electrocatalysts via pyrolysis.Want to read the full publication?https://lnkd.in/gXbvPfUD |

Tuesday publication update! 📖 Dendrite formation during the charging process of zinc-air batteries remains a major problem! In this published work, the authors are looking into the plating and dissolution of zinc dendrites. In situ TEM observations of the zinc deposition and dissolution indicated that dissolution after dendrite growth proceeds from the parts near the root to the tips of the dendrite. It seems that this all has to do with concentration gradients between the electrode surface and the surrounding environment during the initial process of dendrite formation.Interested?
