Management of grossly destroyed endodontically treated teeth with lock and key custom modified cast post and core design: A case series

open access: goldContemporary Clinical Dentistry, 2015
The purpose of this paper is to demonstrate a more retentive custom modified lock and key design of metal cast post and core for the restoration of grossly destroyed endodontically treated molar tooth.

The Development of a Portable Hard Disk Encryption/Decryption System with a MEMS Coded Lock [PDF]

open access: yesSensors, 2009
In this paper, a novel portable hard-disk encryption/decryption system with a MEMS coded lock is presented, which can authenticate the user and provide the key for the AES encryption/decryption module.

Dynamics of particles with “key-lock” interactions [PDF]

open access: greenEPL (Europhysics Letters), 2008
The dynamics of particles interacting by key-lock binding of attached biomolecules are studied theoretically. Examples of such systems include DNA-functionalized colloids as well as nanoparticles grafted with antibodies to cell membrane proteins.

Key‐lock Ceria Catalysts for the Control of Diesel Engine Soot Particulate Emissions [PDF]

open access: yes, 2020
A new concept, referred to as key‐lock catalyst, is presented in this article. Soot combustion ceria catalysts were prepared combining hard (polymethylmethacrylate colloidal crystals) and soft (Pluronic F127) templates, tuning the porosity of ceria in ...

Acoustically levitated lock and key grains

open access: yesPhysical Review Research, 2023
We present a scheme for generating shape-dependent, specific bonds between millimeter scale particles, using acoustic levitation. We levitate particles in an ultrasonic standing wave, allowing for substrate-free assembly.

Rational design of a “dual lock-and-key” supramolecular photosensitizer based on aromatic nucleophilic substitution for specific and enhanced photodynamic therapy

open access: diamondChemical Science, 2020
Photosensitizing agents are essential for precise and efficient photodynamic therapy (PDT). However, most of the conventional photosensitizers still suffer from limitations such as aggregation-caused quenching (ACQ) in physiological environments and ...

Locks fit into keys: a crystal analysis of lock polynomials [PDF]

open access: yesarXiv, 2020
Lock polynomials and lock Kohnert tableaux are natural analogues to key polynomials and key Kohnert tableaux, respectively. In this paper, we compare lock polynomials to the much-studied key polynomials and show that the difference of a key polynomial and lock polynomial for the same composition is monomial positive.

Complementary Lock-and-Key Ligand Binding of a Triplet Transmitter to a Nanocrystal Photosensitizer. [PDF]

open access: greenAngewandte Chemie, 2017
Owing to the difficulty in comprehensively characterizing nanocrystal (NC) surfaces, clear guidance for ligand design is lacking. In this work, a series of bidentate bis(pyridine) anthracene isomers (2,3-PyAn, 3,3-PyAn, 2,2-PyAn) that differ in their ...

The size-selective interaction of key and lock nanocrystals driven by depletion attraction at the nanoscale.

open access: hybridNanoscale, 2018
In this article, we study the size-dependent interactions of quasi-spherical nanocrystals with voids of concave nanoparticles of complementary sizes and shapes.

Electric-Field-Induced Lock-and-Key Interactions between Colloidal Spheres and Bowls [PDF]

open access: green, 2016
To realize new and directed self-assembly (SA) pathways, the focus in colloid science and nanoscience has shifted from spherical particles and interactions to increasingly more complex shapes and interparticle potentials.
