RF Magnetron Sputtered Tungsten Disulfide Films: Influence of Target Preparation, Deposition Parameters, and Storage Conditions on Thin Film Stoichiometry

open access: yesAdvanced Materials Interfaces, EarlyView.
Sputtered WS2 films were investigated in terms of their S‐ and O‐concentration depending on deposition power and pre‐sputter time. Chemical and structural investigations were done using EDS, TEM, SEM, AFM, XRD. In general, 20 W films exhibit a wide variation in stoichiometry and structure whereas 80 W films demonstrate a higher S/W ratio than 20 W ...

Ductility Tuning via Cluster Network Characteristics of Porous Components

open access: yesAdvanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Scalable Task Planning via Large Language Models and Structured World Representations

open access: yesAdvanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

open access: yesAdvanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Learned Conformational Space and Pharmacophore Into Molecular Foundational Model

open access: yesAdvanced Science, EarlyView.
The Ouroboros model introduces two orthogonal modules within a unified framework that independently learn molecular representations and generate chemical structures. This design enables flexible optimization strategies for each module and faithful structure reconstruction without prompts or noise.

Atomic‐Scale Insights into Yttrium‐Induced Grain Boundary Structure Modification in Al2O3

open access: yesAdvanced Science, EarlyView.
Using advanced STEM characterization combined with NNP‐based MCMD calculations, it is revealed that Y segregation at ∑13 Al2O3 GB involves not only simple substitution of Y for Al atoms but also structural adaptation with a change in GB atomic density, leading to minimized excess volume and lowest GB energy.

Application of a modified Monte Carlo method for the simulation of heat conduction in a rectangular slab [PDF]

open access: yesMaejo International Journal of Science and Technology, 2008
Monte Carlo method has been used to study heat conduction problems. It is grid-free inimplementation, unlike the conventional Finite Element and Finite Difference Method.

A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging

open access: yesAdvanced Science, EarlyView.
Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

Clock factorized quantum Monte Carlo method for long-range interacting systems

open access: yesSciPost Physics Core
Simulating long-range interacting systems is a challenging task due to its computational complexity that the computational effort for each local update is of order $\mathcal{O}(N)$, where $N$ is the size of the system.

Direct Growth of Transparent Boron Nitride Neutron Shielding Layer for Space Window

open access: yesAdvanced Science, EarlyView.
Direct growth of sp2‐sp3 hybridized BN (HBN) on quartz, enabled by an h‐BN buffer, produces transparent and stable films up to 80 µm thick with high transmittance and strong neutron shielding, making HBN a promising candidate for space windows in long‐term lunar missions.
