Template‐Assisted Growth of CsxFA1‐xPbI3 with Pulsed Laser Deposition for Single Junction Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Template‐assisted pulsed laser deposition (PLD) enables the growth of phase‐pure α‐CsxFA1‐xPbI3 perovskite films. Stoichiometric transfer and uniform coverage on planar and textured substrates is demonstrated, delivering reproducible single‐junction perovskite solar cells.

A Novel Ti12‐Based Metal‐Organic Framework for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
MIP‐209(Ti) is a new microporous MOF built up from Ti₁₂O₁₅ clusters and substituted terephthalate linkers, enabling isoreticular chemistry and clusters tunability for photocatalytic applications. Cr3⁺ doping (≤5 at%) on Ti‐oxoclusters drastically enhances water stability and boosts hydrogen production from water under simulated solar light irradiation.

Polymorphs and Polymorphic Cocrystals of Temozolomide

Chemistry – An Asian Journal, 2008
AbstractCrystal polymorphism in the antitumor drug temozolomide (TMZ), cocrystals of TMZ with 4,4′‐bipyridine‐N,N′‐dioxide (BPNO), and solid‐state stability were studied. Apart from a known X‐ray crystal structure of TMZ (form 1), two new crystalline modifications, forms 2 and 3, were obtained during attempted cocrystallization with carbamazepine and 3‐

Polymorphism in Benzamide

Angewandte Chemie, 2005
(Figure Presented) At long last, the crystal structure of the metastable form of benzamide, whose existence has been known of for over 170 years, has finally been solved by using a combination of in situ crystallization, high-speed synchrotron X-ray powder diffraction, and global-optimization methods of structure determination (see picture).

On the Polymorphism of Aspirin

Angewandte Chemie International Edition, 2007
More headaches with aspirin: No new polymorph? Reduction and re-indexing of X-ray data collected on a crystal of the well-known form I of aspirin in a unit cell recently reported for the new form II results in a data set from which this so-called new form can be obtained and even refined isotropically! Form II, if it exists, needs to be identified with

Conformational Polymorphism

Chemical Reviews, 2013
An unambiguous definition of conformational change and conformational polymorphism, as well as a quantitative basis for the likelihood of its appearance, is reviewed. Conformational adjustment and conformational change are different phenomena. Two polymorphs are conformational polymorphs only if their conformations are related by conformational change.
