Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

ReaxFF reactive molecular dynamics on silicon pentaerythritol tetranitrate crystal validates the mechanism for the colossal sensitivity [PDF]

open access: yes, 2014
Recently quantum mechanical (QM) calculations on a single Si-PETN (silicon-pentaerythritol tetranitrate) molecule were used to explain its colossal sensitivity observed experimentally in terms of a unique Liu carbon-silyl nitro-ester rearrangement (R_3Si–

Pentaerythritol trinitrate succinate: a hapten for pentaerythritol tetranitrate

open access: yesActa Crystallographica Section E Structure Reports Online, 2006
The title compound, C10H15N3O13, is a derivative of the energetic compound penta­erythritol tetra­nitrate (PETN). It is a hapten (a small mol­ecule which can elicit an immune response only when coupled to a large carrier such as a protein) for PETN and was designed to be more stable and useful in immunochemistry.

Flexible 3D Multi‐Material Printing beyond Layer‐by‐Layer Constraints via Sequential Multi‐Printer Fabrication

open access: yesAdvanced Materials Technologies, EarlyView.
We developed a flexible multi‐material printing strategy that employs sequential printing with different printers. This combined use of printers expands the accessible material scope. Moreover, incorporating Xolography as a sequential step enables support‐free, contactless printing, thereby enhancing structural design flexibility beyond conventional ...

Explanation of the colossal detonation sensitivity of silicon pentaerythritol tetranitrate (Si-PETN) explosive [PDF]

open access: yes, 2009
DFT calculations have identified the novel rearrangement shown here for decomposition of the Si derivative of the PETN explosive [pentaerythritol tetranitrate (PETN), C(CH_2ONO_2)_4] that explains the very dramatic increase in sensitivity observed ...

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.
