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.

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement
Angewandte Chemie, EarlyView.Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization
