State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials
Advanced Materials, EarlyView.Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Development of mathematic model for coffee decaffeination with leaching method
Coffee and Cocoa Research Journal, 2011 A simple mathematic model for caffeine kinetic description during the extraction process (leaching) of coffee bean was developed. A nonsteady diffusion equation coupled with a macroscopic mass transfer equation for solvent was developed and them solved ...

Optical Properties of Synthetic Cannabinoids with Negative Indexes [PDF]
, 2016 Some kinds of psychoactive drugs have the structures which are called split-ring resonators (SRRs). SRRs might result in negative permittivity and permeability simultaneously in electromagnetic field. Simultaneous negative indexes can lead to the famous phenomenon of negative refraction.

Novel C-dots/titanate nanotubular hybrid materials with enhanced optical and photocatalytic properties [PDF]
arXiv, 2022 Advanced nanomaterials with enhanced optical and photocatalytic properties for the photodegradation of organic pollutants, in particular pharmaceuticals and personal care products (PPCPs), were successfully prepared by a swift one-pot synthesis. Nanostructured materials were synthesized through an integrated hydrothermal procedure which generates ...

Induction of chromosome damage by ultraviolet light and caffeine: Correlation of cytogenetic evaluation and flow karyotype [PDF]
, 1982 Asynchrononously growing cells of a M3-1 Chinese hamster line were ultraviolet (UV) irradiated ( = 254 nm) with UV fluences up to 7.5 J/m2. After irradiation, cells were incubated with or without 2 mM caffeine for 20 hr, then mitotic cells were selected ...

Neuropsychological Effects of Caffeine: Is Caffeine Addictive? [PDF]
Journal of Psychology & Psychotherapy, 2017 Caffeine is the most widely used psychotropic drug in the world. Most of the caffeine consumed comes from coffee bean (i.e., a misnomer for the seed of Coffee plants), beverages (i.e., coffee, tea, soft drinks), in products containing cocoa or chocolate and in medications (i.e., analgesics, stimulants, weight-loss products, sports nutrition).
