From Snapshots to Development: Identifying the Gaps in the Development of Stem Cell‐based Embryo Models along the Embryonic Timeline

open access: yesAdvanced Science, Volume 8, Issue 8, April 21, 2021., 2021
This progress report aims to highlight some of the potential gaps in the developmental timeline of synthetic stem cell‐based embryo models relative to natural embryogenesis and provides innovative bioengineering solutions to understand and eventually improve the modeling of mammalian embryo development in the future. Abstract In recent years, stem cell‐

Trophoblast lineage specification in the mammalian preimplantation embryo

open access: yesReproductive Medicine and Biology, Volume 19, Issue 3, Page 209-221, July 2020., 2020
Early blastomere which starts differentiation toward the TE cell fate still have has plasticity and can change its fate to ICM lineages depending on their positional changes. Abstract Background The establishment of the trophectoderm (TE) and the inner cell mass (ICM) is the first cell lineage segregation that occurs in mammalian preimplantation ...

Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.

Reliability improvement in BaTiO3‐based multilayer ceramic capacitors by incorporating alloying of nickel internal electrodes

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract The mechanism of the reliability improvement by alloying Ni internal electrodes of BaTiO3‐based multilayer ceramic capacitors (MLCCs) was studied from two perspectives: electric barrier formation at the electrode‐dielectric interface and diffusion of alloying elements into the bulk dielectric layer.
