AI Article Synopsis
- Interfacial interactions between active cathode materials and solid electrolytes are crucial for the performance of solid-state batteries.
- (S)TEM imaging helps analyze the atomic structure and composition at these interfaces, but preparing TEM specimens from loosely bound composites using traditional methods leads to difficulties like breakage.
- The authors introduce a new technique that uses a protective frame created by the FIB's gas injection system to prevent sample damage, which can also benefit other research areas involving loosely bound materials.
Article Abstract
Interfacial phenomena between active cathode materials and solid electrolytes play an important role in the function of solid-state batteries. (S)TEM imaging can give valuable insight into the atomic structure and composition at the various interfaces, yet the preparation of TEM specimen by FIB (focused ion beam) is challenging for loosely bound samples like composites, as they easily break apart during conventional preparation routines. We propose a novel preparation method that uses a frame made of deposition layers from the FIB's gas injection system to prevent the sample from breaking apart. This technique can of course be also applied to other loosely bound samples, not only those in the field of batteries.

Quality deterioration mechanism of freeze-thawed sweet potato oat dough: In terms of ice crystals and protein changes.
J Food Sci
January 2025
College of Tourism and Culinary Science, Yangzhou University, Yangzhou, China.
Sweet potato-oat composite dough is a nutritious, functional dough with promising market potential. This study investigates its quality changes during freeze-thaw cycles from the perspectives of ice crystals and protein alterations to provide theoretical support for its processing and production. After freeze-thaw cycles, both the storage modulus and loss modulus of the dough decrease, resulting in increased hardness, reduced resilience and chewiness, lower sensory scores, decreased specific volume, and darker color.

This study investigates the interaction of amino-modified starch nanoparticles (NH-SNPs) and unmodified SNPs with pepsin and trypsin and the influence of the formation of protein coronas on the release of polyphenols. We discovered that NH-SNPs bound loosely to pepsin, while they bound tightly to trypsin, by quartz crystal microbalance with dissipation monitoring and zeta potential measurement. SNPs did not easily bind to the two digestive enzymes.

Macauba fruit pulp (Acrocomia aculeata) is an emerging oil source. After de-oiling, the macauba pulp meal (MPM) offers a dietary fiber content of 40-50 %, which mainly comprises cell wall polysaccharides (CWP). The present work aimed to assess the potential of MPM as an innovative source of sustainable food polysaccharides.

Phosphorus in crucial for all living organisms. In vertebrate, cellular phosphate homeostasis is partly controlled by XPR1, a poorly characterized inositol pyrophosphate-dependent phosphate exporter. Here, we report the cryo-EM structure of human XPR1, which forms a loose dimer with 10 transmembrane helices (TM) in each protomer.

Copper is an essential nutrient for sustaining vital cellular processes spanning respiration, metabolism, and proliferation. However, loss of copper homeostasis, particularly misregulation of loosely bound copper ions which are defined as the labile copper pool, occurs in major diseases such as cancer, where tumor growth and metastasis have a heightened requirement for this metal. To help decipher the role of copper in the etiology of cancer, we report a histochemical activity-based sensing approach that enables systematic, high-throughput profiling of labile copper status across many cell lines in parallel.
