Acid–base bifunctional catalysis can be categorized into two types; a type in which acid and base interact simultaneously with the substrate, and a type in which acid and base interact successively with the substrate and the transformed substrate. The former simultaneous interaction of acid and...

The effect of the metal/acid balance of Pt/SiO2–Al2O3 catalysts on the catalytic transformation of sorbitol in aqueous medium was investigated, using four mechanical mixtures of Pt/SiO2–Al2O3 and SiO2–Al2O3 (100:0; 50:50; 25:75; 0:100). The results show that the metal/acid balance has a stron...

Bifunctional metal/acid catalysts of 5 wt% Ni/HBeta, 5 wt% Fe/HBeta, 2.5 wt% Ni-2.5 wt% Fe/HBeta (NiFe-5/HBeta) and 5 wt% Ni-5 wt% Fe/HBeta (NiFe-10/HBeta) were used for hydrodeoxygenation (HDO) of a simulated phenolic bio-oil consisting of phenol (50 wt%), o-cresol (25 wt%) and guaiacol (25 wt%...

Catalytic hydrodeoxygenation (HDO) is a promising technology for improving the properties of pyrolysis bio-oils. However, the role that intermolecular reactivity between the numerous chemical components of bio-oil plays on the overall performance of the process has been scarcely investigated. In...

The mass and coupling of the doubly charmed JP=0− diquark–antidiquark states Tcc;s¯s¯++ and Tcc;d¯s¯++ that bear two units of the electric charge are calculated by means of QCD two-point sum rule method. Computations are carried out by taking into account vacuum condensates up to and includ...

This paper addresses the single-item single-stocking location non-stationary stochastic lot sizing problem under the (s, S) control policy. We first present a mixed integer non-linear programming (MINLP) formulation for determining near-optimal (s, S) policy parameters. To tackle larger instance...

We present the python package reskit, developed to calculate the coefficients of an analytical continuation of the S-matrix of a physical system by means of Padé approximants and, from this fit, determine the complex poles of this S-matrix.The current implementation of the program is restricted...

Until now, there are no publications about the preformulation studies on (S)-zaltoprofen ((S)-ZPF). Hence, we first investigated the solubility of (S)-ZPF, screened solubilizers and performed the pharmacokinetic study of (S)-ZPF in the presence of the solubilizers. The measurement of the solubil...

A C4A3$-C2S (ye'elimite-belite) clinker system with different C2S and C4A3$ contents is synthesized from analytical reagents and a C4A3$-C2S hydration system is established with a water-cement ratio of 0.4. The traces of calcium hydroxide or portlandite (CH) in the C4A3$-C2S hydration syste...

An intramolecular-intermolecular cascade cyclization reaction via multi metal-carbene intermediates has been developed. This reaction uses catalytic amount of Nd(OTf)3, which actives both alkyne and aldehyde moieties. This protocol provides a novel strategy for the synthesis of phenanthro[9,10-b...

In recent years, there has been a marked increase in the use of recreational synthetic psychoactive substances, which is a cause of concern among healthcare providers and legal authorities. In particular, there have been reports on the misuse of 5-(2-aminopropyl)indole (5-API; 5-IT), a new synth...

In recent years, use of psychoactive synthetic stimulants has grown rapidly. 5-(2-Aminopropyl)indole (5-IT) is a synthetic drug associated with a number of fatalities, that appears to be one of the newest 3,4-methylenedioxymethamphetamine (MDMA) replacements. Here, the monoamine-releasing proper...

Metabolic potency of des-(B26–B30)-insulin-B25-amide, [TyrB25]des-(B26–B30)-insulin-B25-amide and [HisB25]des-(B26–B30)-insulin-B25-amide was studied in anaesthetized rats. Compared to insulin, full potency for des-(B26–B30)-insulin-B25-amide and an enhanced potency for both substituted anal...

Subcutaneous injections of soluble human insulin and of the monomeric insulin analogue des-(B26–B30)-insulin-B25-amide were given to fasted rabbits, pigs and healthy man. The time course of blood glucose decline and the rate of appearance of the hormones in the peripheral circulation were studi...

In this work, the growth of thin Zn films on 4H-SiC(0001)graphene and the effects of system annealing at various temperatures are presented. Metal growth on graphene is interesting to understand the grown morphology and metal intercalation, to use it to tune graphene properties. The properties s...

This work reports on the effect of high temperature annealing on the electrical properties of p-type implanted 4H-SiC. Ion implantations of Aluminum (Al) at different energies (30–200 keV) were carried out to achieve 300 nm thick acceptor box profiles with a concentration of about 1020 at/cm3. ...

4H-SiC Schottky photodiodes, with 25μm epitaxial layers, employing thin (20 nm) Ni2Si Schottky contacts, were investigated for high temperature photon counting X-ray spectroscopy. Important X-ray photodiode detector parameters were extracted from electrical characterization within the temperatu...

We investigated the electrical and interfacial properties of AlN/4H-SiC interfaces prepared by atomic layer deposition (ALD). The conductance–voltage (G/ω–V) characteristics were identified based on two types of traps: fast and slow. Fast traps located in the semiconductor energy gap close to...
