Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods

Chemistry – A European Journal, EarlyView.
We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Lorentz Symmetry Derived from Lorentz Violation in the Bulk [PDF]

, 2006
We consider bulk fields coupled to the graviton in a Lorentz violating fashion. We expect that the overly tested Lorentz symmetry might set constraints on the induced Lorentz violation in the brane, and hence on the dynamics of the interaction of bulk ...

Potential of solid‐state microwaves in lab‐scale chemical‐process development

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The integration of a solid‐state microwave (MW) generator into a newly designed, versatile MW reactor ensures improved energy efficiency, precise process control and broader application potential. In its most particular feature, the device supports the modification of dielectric‐radiation orientation and can be operated under ...

Analysis of Cubic Boron Nitride Single Crystal Defects Growth under High Temperature and High Pressure

Journal of Chemistry, 2020
Cubic boron nitride (cBN) single crystals are synthesized under high temperature and high pressure in the Li-based system. The growth defects on hexagonal and triangular (111) surfaces of cBN single crystals after rapid cooling are discussed systemically

Changes in phenolic profile, physicochemical properties and sensory attributes of steamed bread fortified with golden kiwifruit (Actinidia chinensis) flour during processing

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Chinese steamed bread (CSB) is a traditional East Asian staple. Its texture and nutrition depend on the gluten and starch content of the wheat flour that it contains. Incorporation of golden kiwifruit, which is rich in dietary fiber, vitamin C, and phenolic antioxidants, offers a novel fortification strategy.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Modulation of human platelet activation and in vivo vascular thrombosis by columbianadin: regulation by integrin αIIbβ3 inside-out but not outside-in signals

Journal of Biomedical Science, 2020
Background Columbianadin (CBN) is one of the main coumarin constituents isolated from Angelica pubescens. The pharmacological value of CBN is well demonstrated, especially in the prevention of several cancers and analgesic activity.

Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

The Philippine Center for Investigative Journalism (PCIJ) and ABS-CBN through the Prisms of Herman and Chomsky's "Propaganda Model": Duterte's Tirade against Media and vice versa [PDF]

, 2018
This paper is an attempt to localize Herman and Chomsky’s analysis of the commercial media and use this concept to fit in the Philippine media climate. Through the propaganda model, they introduced the five interrelated media filters which made possible ...
