Intramolecular hydrogen bonding (IAHB) is one of the most important intramolecular interactions and a critical element in adopted molecular arrangements. Moreover, slight substitution in a molecule can affect its strength to a great extent. It is well established that alkyl groups play a positive role in IAHB strength. However, the effects that drive it are specific to each system. To investigate the influence of IAHB and its strength dependency on different acyclic compounds, the conformational preferences of propane-1,3-diol, 3-methoxypropan-1-ol, 3-ethoxypropan-1-ol, 3-isopropoxypropan-1-ol, 3-(tert-butoxy)propan-1-ol, butane-1,3-diol, 3-methoxybutan-1-ol, 3-methylbutane-1-diol, and 3-methoxy-3-methylbutan-1-ol were evaluated experimentally using infrared spectroscopy theoretically supported by topological and natural bond orbital analyses...

Two types of multi-walled carbon nanotubes (CNT and CNT-OH) at different levels (0.1-0.9wt%) were introduced into starch matrix in order to modify its functional properties. The optimum concentration of each nanotube was selected based on results of water solubility, water permeability and mechanical experiments. The physico-mechanical data showed that CNT up to 0.7wt% led to a notable increase in water resistance, water barrier property and tensile strength, whilst regarding CNT-OH, these improvements found at 0...

In this paper, the effects of character strengths on the physiological reactivity to social anxiety induced by the Trier Social Stress Task were reported. On the basis of their scores in the Chinese Virtues Questionnaire, 30 college students were assigned to either high- (n = 15) or low-character-strength (n = 15) groups. Their psychological stress and physiological data across three laboratory stages (namely, baseline, stress exposure, and post-stress) were collected. Results indicated that individuals with high character strengths exhibited rapid cardiovascular recovery from baseline to post-stress even if high- and low-character-strength groups showed similar patterns of cardiovascular arousal in response to the stress at baseline and stress exposure...

A family of silica-supported, magnetite nanoparticle catalysts was synthesised and investigated for continuous-flow acetic acid ketonisation as a model pyrolysis bio-oil upgrading reaction. The physico-chemical properties of Fe3O4/SiO2 catalysts were characterised by using high-resolution transmission electron microscopy, X-ray absorption spectroscopy, X-ray photo-electron spectroscopy, diffuse reflectance infrared Fourier transform spectroscopy, thermogravimetric analysis and porosimetry. The acid site densities were inversely proportional to the Fe3O4 particle size, although the acid strength and Lewis character were size-invariant, and correlated with the specific activity for the vapour-phase acetic ketonisation to acetone...

Biomimetic mineralized hybrid scaffolds are widely used as natural bone substitute materials in tissue engineering by mimicking vital characters of extracellular matrix (ECM). However, the fabrication of hybrid scaffolds with suitable mechanical properties and good biocompatibility remains a challenge. To solve the problems mentioned above, biomimetic calcium phosphate mineralized organic-inorganic hybrid scaffold composed of nano hydroxyapatite (nHAP), Chitosan (CS), Chondroitin sulfate (CSA) and hyaluronic acid (HA) with hierarchical micro/nano structures was successfully developed...

Physical properties of Alaska pollock surimi paste were investigated as affected by pH (4.0 and 6.0-10.0) and heating conditions (slow and fast). The highest values of gel strength and deformability, as shown by breaking force and penetration distance, were obtained at pH 7.5-8.0, while the lowest values were at pH 10.0 followed by pH 6.0 and pH 6.5, respectively. Two-step slow heating process increased the breaking strength value nearly two times higher than one-step fast heating. The effect of pH was strikingly high at pH 7...

The quantitative relationship between analytes established by the headspace solid-phase microextraction procedure for multicomponent mixtures depends not only on the character and strength of interactions of individual components with solid-phase microextraction fiber but also on their vapor pressure in the applied headspace solid-phase microextraction system. This study proves that vapor pressure is of minor importance when the sample is dissolved/suspended in a low-volatility liquid of the same physicochemical character as that of the used solid phase microextraction fiber coating...

BACKGROUND: Childhood aggressive antisocial behavior (CD) is one of the strongest predictors of mental health problems and criminal behavior in adulthood. The aims of this study were to describe personality profiles in children with CD, and to determine the strength of association between defined neurodevelopmental symptoms, dimensions of character maturity and CD. METHODS: A sample of 1886 children with a close to equal distribution of age (9 or 12) and gender, enriched for neurodevelopmental and psychiatric problems were selected from the nationwide Child and Adolescent Twin Study in Sweden...

When activating muscles, motor neurons in the spinal cord also activate Renshaw cells, which provide recurrent inhibitory feedback to the motor neurons. The tight coupling with motor neurons suggests that Renshaw cells have an integral role in movement, a role that is yet to be elucidated. Here we used the selective expression of the nicotinic cholinergic receptor alpha 2 (Chrna2) in mice to genetically target the vesicular inhibitory amino acid transporter (VIAAT) in Renshaw cells. Loss of VIAAT from Chrna2(Cre) expressing Renshaw cells did not impact any aspect of drug-induced fictive locomotion in the neonatal mouse, nor did it change gait, motor coordination or grip strength in adult mice of both sexes...

Phentolamine is one of the most representative nonselective α-adrenoreceptor blocking agents, which have been proved to be owned various pharmacological actions. Unfortunately, whether erythrocytes in the veins intervene in biological behaviors of such drug are largely obscured. With the aid of multiple biophysical techniques, this scenario was to detailed explore the potential biorecognition between phentolamine and the hemeprotein in the cytosol of erythrocytes, and the influences of dynamic characters of protein during the bioreaction...

The Lewis acidity of isolated framework metal sites in Beta zeolites was characterized with (15)N isotopically labeled pyridine adsorption coupled with magic-angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy. The (15)N chemical shift of adsorbed pyridine was found to scale with the acid character of both Lewis (Ti, Hf, Zr, Nb, Ta, and Sn) and Brønsted (B, Ga, and Al) acidic heteroatoms. The (15)N chemical shift showed a linear correlation with Mulliken electronegativity of the metal center in the order Ti < Hf < Zr < Nb < Ta < Sn < H(+)...

Adolescent character development is a high priority for educators, policymakers, and front-line youth workers. To meet this growing demand, and as exemplified in the five articles in this special section, character development scholars are drawing from a range of academic disciplines to push beyond the traditional boundaries of the science of character development. These articles highlight important trends in character research, including the co-development of a subset of character strengths, the articulation of developmental trajectories of character, the use of advanced methodological approaches, and the implications for education...

Molecular compounds, organic and inorganic, crystallize in diverse and complex structures. They continue to inspire synthetic efforts and "crystal engineering", with implications ranging from fundamental questions to pharmaceutical research. The structural complexity of molecular solids is linked with diverse intermolecular interactions: hydrogen bonding with all its facets, halogen bonding, and other secondary bonding mechanisms of recent interest (and debate). Today, high-resolution diffraction experiments allow unprecedented insight into the structures of molecular crystals...

The electronic structures of the antifluorite-type compound Mg2 Si is described in which a sublattice of short cation-cation contacts creates a very low conduction band minimum. Since Mg2 Si shows n-type conductivity without intentional carrier doping, the present result indicates that the cage defined by the cations plays critical roles in carrier transport similar to those of inorganic electrides, such as 12 CaO⋅7 Al2 O3 :e(-) and Ca2 N. A distinct difference in the location of conduction band minimum between Mg2 Si and the isostructural phase Na2 S is explained in terms of factors such as the differing interaction strengths of the Si/S 3s orbitals with the cation levels, with the more core-like character of the S 3s leading to a relatively low conduction band energy at the Γ point...

Temperature and composition dependences of the I41/amd → [Formula: see text] phase transition in the Mg x Cu1 - x Cr2O4 spinel solid solution, due to the melting of the cooperative Jahn-Teller distortion, have been studied by means of single-crystal X-ray diffraction. Crystals with x = 0, 0.10, 0.18, 0.43, 0.46, 0.53, 1 were grown by flux decomposition methods. All crystals have been refined in the tetragonal I41/amd space group except for the Mg end-member, which has cubic symmetry. In Mg x Cu1 - x Cr2O4 the progressive substitution of the Jahn-Teller, d(9) Cu(2+) cation with spherical and closed-shell Mg(2+) has a substantial effect on the crystal structure, such that there is a gradual reduction of the splitting of a and c unit-cell parameters and flattening of the tetrahedra...

The mechanism of intramolecular singlet fission in donor-acceptor-type copolymers, especially the role of the dark 2Ag state, is not so clear. In this Letter, the electronic structure of the benzodithiophene (B)-thiophene-1,1-dioxide (TDO) copolymer is calculated by density matrix renormalization group theory with the Pariser-Parr-Pople model. We find that the dark 2Ag state is the lowest singlet excited state and is nearly degenerate with the 1Bu state. So, a fast internal conversion from 1Bu to 2Ag state is highly possible...

Hydrogels with good mechanical properties, excellent biocompatibility and designable shapes are of great importance for their biomedical applications. Herein, a series of high strength, biocompatible hydrogels have been synthesized by integrating sodium citrate into the thermally reversible chitosan/gelatin to form multiple physically crosslinking networks. Besides the ideal formability, a thermal etching or welding method has been developed to program the surface morphology and fabricate hydrogels with complicated shapes freely...

In order to increase computation power and efficiency, the semiconductor industry continually strives to reduce the size of features written using lithographic techniques. The planned switch to a shorter wavelength extreme ultraviolet (EUV) source presents a challenge for the associated photoresists, which in their current manifestation show much poorer photoabsorption cross sections for the same dose. Here we consider the critical role that an inner-shell electronic structure might play in enhancing photoabsorption cross sections, which one can control by the choice of substituent elements in the photoresist...
