Abstract The optimum scaffold for tissue engineering must guarantee the mechanical integrity in the damaged zone and ensure an appropriate stiffness to regulate the cellular function. For this to happen, scaffolds must be designed to match the stiffness of the native tissue. Moreover, the degradation rate in the case of bioresorbable materials must be also considered to fit the tissue regeneration rate. This paper presents a methodology based on Design of Experiments, Finite Element Analysis, metamodels...

The numerical results demonstrate that the incorporation of residual...
Abstract Model‐based prediction of Fractional Flow Reserve (FFR) in the context of stable Coronary Artery Disease (CAD) diagnosis requires a number of modelling assumptions. One of these assumptions is the definition of a baseline coronary flow, i.e. total coronary flow at rest prior to the administration of drugs needed to perform invasive measurements. Here we explore the impact of several methods available in the literature to estimate and distribute baseline coronary flow on FFR predictions...

Importantly, 1 is the first luminescence probe for detecting both concentrated alkali (20 M NaOH) and strong acid (1 M HNO3) with high selectivity and repeatability....
Synthetic anion transporters that facilitate transmembrane H+/Cl− symport (cotransport) have anti‐cancer potential due to their ability to neutralize pH gradients and inhibit autophagy in cells. However, compared to the natural product prodigiosin, synthetic anion transporters have low‐to‐modest H+/Cl− symport activity and their mechanism of action remains less well understood. We report a chloride‐selective tetraurea macrocycle that has a record‐high H+/Cl− symport activity similar to that of prodigiosin...

Superior to linear peptides in biological activities, cyclic peptides are considered to have great potentials used as therapeutic agents. In order to identify cyclic peptide ligands for therapeutic targets, selection from phage‐displayed peptide libraries in which cysteines are conjugated covalently through either the disulfide bond or organic linkers has been widely adopted with great success. To resolve some technical drawbacks related to cysteine conjugation, we have invented a novel phage display...

A pyridine‐pyridine coupling reaction has been developed between pyridyl phosphonium salts and cyanopyridines using B2pin2 as an electron‐transfer reagent. Complete regio‐ and cross‐selectivity are observed when forming a range of valuable 2,4’‐bipyridines. Phosphonium salts were found to be the only viable radical precursors in this process, and mechanistic studies indicate that the process does not proceed via Minisci‐type coupling involving a pyridyl radical. Instead, a radical‐radical coupling...
The intramolecular coupling of two C(sp3)–H bonds to forge a C(sp3)–C(sp3) bond is enabled by 1,4‐Pd shift from a trisubstituted aryl bromide. Contrary to most C(sp3)–C(sp3) cross‐dehydrogenative couplings, this reaction operates under redox‐neutral conditions, with the C–Br bond acting as an internal oxidant. In addition, it allows the coupling between two moderately acidic primary or secondary C–H bonds, i. e. adjacent to an oxygen or nitrogen atom on one side, and benzylic or adjacent to a carbonyl...
Multicolor emissive materials consisting of a single luminophore, a Lewis acid, and their complex were developed. The emissive colors can be tuned by changing the concentration of the solution and the ratio of mixed solvents. Various emissive colors in the solid state were observed by mixing the complexes into polymers in different amounts. The color change is due to equilibrium disruption between the single luminophore, Lewis acid, and its complex. White emission was observed by appropriately controlling...
A pincer‐iridium complex bearing a Lewis‐base‐free X‐type alumanyl ligand was synthesized.

The resulting complex was applied as a catalyst for transfer dehydrogenation of cyclooctane.
Systems chemistry aims to mimic the functional behavior of living systems by constructing chemical reaction networks with well‐defined dynamic properties.

The molecule (E)‐(5‐(3‐anthracen‐9‐yl‐allylidene)‐2,2‐dimethyl‐[1,3] dioxane‐4,6‐dione) (E‐AYAD) undergoes an E→Z photoisomerization. In the solid‐state, this photoisomerization can initiate a physical transformation of the crystal that is accompanied by a large volume expansion (~10 times), loss of crystallinity, and the growth of large pores. This physical change requires conversion of the ~10% conversion of the E to Z isomer and results in a gel‐like solid with decreased stiffness that still...
Doping, through oxidation or reduction, is often used to modify the properties of π‐conjugated oligomers. In most cases, the resulting charge distribution is difficult to determine. If the oligomer is cyclic and doping establishes global aromaticity or antiaromaticity, then it is certain that the charge is fully delocalized over the entire perimeter of the ring. Here we show that reduction of a six‐porphyrin nanoring using decamethylcobaltocene results in global aromaticity (in the 6– state; [90...

Trigonal hexakis‐ and nonakisimidazolium salts were used to prepare metallosupramolecular assemblies featuring 6 or 9 MI (M=Ag, Au) ions. Functionalization of the trigonal poly‐NHCs enabled a photochemically induced [2+2] cycloaddition connecting the poly‐NHCs via cyclobutane linkers. Removal of the template metal ions yielded polyimidazolium cations with 12 or 18 imidazolium groups and potentially large cavities. Abstract Metallosupramolecular poly‐NHC‐metal assemblies were prepared from trigonal...
Vicinal scalar couplings (3J) are extensively used for conformational analysis of organic compounds in the liquid state through the use of empirical Karplus equations.
