Modular Molecular Design and Self‐Assembled Nanostructures of Saccharide‑Appended Cyclic Dipeptides for Glycosidase‑Responsive Supramolecular Hydrogels

open access: yesSmall, EarlyView.
Saccharide‐appended cyclic dipeptides are designed and developed as building blocks for glycosidase‐responsive supramolecular hydrogels. Their aqueous self‐assembly enables β‐galactosidase‐triggered gel‐to‐sol and neuraminidase‐triggered sol‐to‐gel transition systems, highlighting their potential as glycosidase‐responsive soft materials for biomedical ...

La importancia de contar con estrategias eficientes de aprendizaje que ayuden a fortalecer y retener los conocimientos ya aprendidos a los estudiantes universitarios.

open access: yes, 2018
La investigación bibliográfica ha llevado al descubrimiento que el problema de no contar con estrategias de aprendizaje en los estudiantes universitarios, no es exclusivo de un solo Programa Académico, sino que se presenta en distintos ámbitos desde lo ...

Large‐Scale Structural Dynamics in the Tail Fiber Modulate the Infective Transition of the T7 Bacteriophage

open access: yesSmall, EarlyView.
During host recognition, the fibers of T7 bacteriophages transition from a capsid bound state to an extended conformation, which requires some level of fiber flexibility. By using high‐speed atomic force microscopy, we show that the fibers have an internal molecular hinge and a torsionally compliant coiled‐coil region.

Hot Injection Synthesis of Ultrathin Bi2Se3 Nanosheets With Controllable Dimensions

open access: yesSmall Methods, EarlyView.
Graphic of hot‐injection method for synthesizing Bi2Se3${\rm Bi}_2{\rm Se}_3$ nanoplatelets of controlled shape, thickness, and lateral size. The ultra‐thin regime is achievable, which is interesting for studying topological phase transitions. ABSTRACT In this work, a synthesis method for colloidal nanoplatelets (NPLs) of the topological insulator ...

Phase‐Controllable Synthesis and Property Modulation of Two‐Dimensional PAs3S3 Crystal

open access: yesSusMat, EarlyView.
For the first time, phase‐controllable synthesis of 2D inorganic molecular crystals PAs3S3 are successfully realized by kinetics‐controlled vertical microspacing sublimation method. Due to the different arrangements of molecules, the two phases exhibit distinct SHG property, intermolecular forces, and Young's modulus of the R3m phase (21.31 GPa) is 69%
