Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Synthesis and Reactivity of New 1-Pentafluorophenyl-1Hpyrrole Derivatives

open access: yesMolecules, 2003
We present 1-pentafluorophenyl-1H-pyrrole and some of its electrophilic substitution reactions: formylation and acetylations. The 2-substituted products formed in these reactions are selectively and in high yield converted into 3-substituted products by ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Synthesis of Non-Aromatic Pyrroles Based on the Reaction of Carbonyl Derivatives of Acetylene with 3,3-Diaminoacrylonitriles

open access: yesMolecules, 2023
The reaction of 3,3-diaminoacrylonitriles with DMAD and 1,2-dibenzoylacetylene was studied. It is shown that the direction of the reaction depends on the structure both of acetylene and of diaminoacrylonitrile. In the reaction of DMAD with acrylonitriles

A facile route to pyrroles, isoindoles and hetero fused analogues

open access: yes, 2002
Enamino acids derived from 1,2-dimethylaminomethylene- or 1,2-hydroxymethylene-carbonyl compounds and amino acids undergo a decarboxylative cyclisation to pyrroles, isoindoles and other fused pyrroles. A two atom ring expansion occurs preferentially with
