Hexagonal dielectric resonators and microcrystal lasers [PDF]

, 2002
We study long-lived resonances (lowest-loss modes) in hexagonally shaped dielectric resonators in order to gain insight into the physics of a class of microcrystal lasers.

Controlling the structure and properties of semi-crystalline cellulose/silk-fibroin biocomposites by ionic liquid type and hydrogen peroxide concentration

Carbohydrate Polymer Technologies and Applications, 2022
This work reports how to tune the semi-crystallinity of a blended microcrystalline cellulose/silk-fibroin biocomposite using ionic liquids and various coagulation agents.

An approach to MOFaxanes by threading ultralong polymers through metal–organic framework microcrystals

Nature Communications, 2023
Mechanically interlocked architecture has inspired the fabrication of numerous molecular systems, such as rotaxanes, catenanes, molecular knots, and their polymeric analogues. However, to date, the studies in this field have only focused on the molecular-

Zeolite-dye micro lasers [PDF]

, 1998
We present a new class of micro lasers based on nanoporous molecular sieve host-guest systems. Organic dye guest molecules of 1-Ethyl-4-(4-(p-Dimethylaminophenyl)-1,3-butadienyl)-pyridinium Perchlorat were inserted into the 0.73-nm-wide channel pores of ...

Study on the microcrystal cellulose and the derived 2D graphene and graphene microcrystal

, 2023
Abstract Microcrystal cellulose (MCC) is a green and sustainable resource that widely exists in various lignocellulose species in percentage 10–30%. The fine powder of MCC is often discarded in industrial productions that use lignocellulose as feedstock.

Scientific problem of metal melts. Solutions

Литьë и металлургия, 2019
In the existing theories of liquid state of metals and alloys the basic structural element is atom. It creates a serious problem in scientific understanding of the mechanism of process of melt and properties of metal melts.

Microcrystal manipulation with laser tweezers [PDF]

Acta Crystallographica Section D Biological Crystallography, 2013
X-ray crystallography is the method of choice to deduce atomic resolution structural information from macromolecules. In recent years, significant investments in structural genomics initiatives have been undertaken to automate all steps in X-ray crystallography from protein expression to structure solution.

Protocol for the use of focused ion-beam milling to prepare crystalline lamellae for microcrystal electron diffraction (MicroED)

STAR Protocols, 2021
Summary: We present an in-depth protocol to reproducibly prepare crystalline lamellae from protein crystals for subsequent microcrystal electron diffraction (MicroED) experiments.

An Atomic Linear Stark Shift Violating P But Not T Arising From the Electroweak Nuclear Anapole Moment [PDF]

, 2001
We propose a direct method of detection of the nuclear anapole moment. It is based on the existence of a linear Stark shift for alkali atoms in their ground state perturbed by a quadrupolar interaction potential and a magnetic field.
