An Expedition on Alkali and Alkaline‐Earth Isocyanurate Hydrates: Structure Elucidation, Thermogravimetry, and Spectroscopy

open access: yes, 2017
Several alkali and alkaline earth (iso)cyanurates were synthesized by simple aqueous acid-base reactions and aqueous salt metathesis reactions, respectively, yielding nine new structure types.

Thermal Stability of Azurite and Malachite in Relation to the Formation of Mediaeval Glass and Glazes [PDF]

open access: yes, 2002
Azurite and malachite have been extensively used as pigments in ancient and medieval manuscripts, glasses and glazes. The thermal stability of naturally occurring azurite and malachite was determined using a combination of controlled rate thermal ...

Side‐Chains Engineered Self‐Assembly of Ortho‐Benzodipyrrole‐Based Acceptors: Comprehensive Exploration of Structure‐Interface‐Photovoltaics Correlations

open access: yesAdvanced Functional Materials, EarlyView.
The side‐chain configuration in the bay region of C‐shaped ortho‐benzodipyrrole‐based non‐fullerene acceptors plays a crucial role in their self‐assembly, single‐crystal structures, and optoelectronic properties. The closely correlated molecular structure and performance underscore the importance of minimizing A–A self‐aggregation and enhancing D–A ...

A NEW METHOD OF DETERMINATION OF CALCIUM ORTHOPHOSPHATE AND ASSOCIATED IMPURITIES BY THERMOGRAVIMETRY AND DERIVATIVE THERMOGRAVIMETRY

open access: yesJournal of Food Quality, 1979
ABSTRACTCalcium orthophosphte (TCP) is known to be a nutritional additive in processed foods and wheat flour. Only pure salt is highly toxic to stored product insects. However, commercial salts were found to contain other monobasic and dibasic calcium phosphates and carbonates of calcium and magnesium which reduce insecticidal potency and affect food ...

Reversible Phase Transitions Enable Cyclic Isothermal CO2 Capture in Redox‐Activated Perovskite‐Structured Sorbents

open access: yesAdvanced Functional Materials, EarlyView.
Perovskite‐structured SrMnO3 can cyclically and reversibly capture and release CO2 via redox‐enabled phase transitions at constant temperature. The efficacy of this novel redox‐activated CO2 sorbent is demonstrated via sorption‐enhanced steam methane reforming.

Polyphenolic resin synthesis: optimizing plantain peel biomass as heavy metal adsorbent

open access: yesPolímeros, 2015
Polyphenolic resol resins were obtained from an ethanolic extraction of green plantain peels (Musa paradisiaca) grown in Colombia. A synthesis was then performed by polycondensation in an alkaline pH solution in order to perform research on phenolic ...

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces

open access: yesAdvanced Functional Materials, EarlyView.
The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Drug-Excipient Compatibility Studies in Formulation Development: Current Trends and Techniques [PDF]

open access: yes, 2015
The safety, efficacy, quality and stability of a formulation are the cornerstones of any new drug development process. In order to consistently maintain these attributes in a finished dosage form, it is important to have a comprehensive understanding of ...

Ultrahigh‐resolution (λ/10) Femtosecond Laser Writing of Polymer‐Encapsulated Multicolor Perovskite Patterns Beyond the Diffraction Limit

open access: yesAdvanced Functional Materials, EarlyView.
Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.
