The aim of this work is the experimental validation of a steady-state and transient ejector model for high temperature fuel cell hybrid system applications. This is a mandatory step in performing the steady state and the transient analysis of the whole plant to avoid critical situations and to develop the control syst…

In the present paper, by using a specially designed experiment, we analyze the relationship between the acoustic emission and the deformation resulting from front propagation during a stress-induced transition from cubic to a single-variant martensite in a Cu-Zn-Al single crystal. The front propagates by nucleation an…
Recent developments in understanding the central place of mitochondria as regulators of programmed cell death have stimulated enormous interest in using them as targets for cancer chemotherapy. To overcome drug resistance and the lack of selectivity of cancer drugs in differentiating between normal and tumour cells, m…
Abstract The pressure dependences of three adiabatic elastic constants, adiabatic bulk modulus, refractive index, and elastic anisotropy, as well as Cauchy deviation of fcc solid Xe have been determined up to 10 GPa at 296 K by high‐pressure Brillouin scattering spectroscopy. The characteristics of elastic properties…
A new environmentally friendly strategy for the sustainable functionalization of inert man-made polymer surfaces is mapped out for the first time using a combination of plasma pretreatment and enzymatic postgrafting. The efficiency of enzymatic covalent binding is investigated by grafting methacrylate monomers possess…
Appropriate three-dimensional (3D) scaffolds and signal molecules could accelerate tissue regeneration and wound repair. In this work, we targeted human basic fibroblast growth factor (bFGF), a potent angiogenic factor, to a fibrin scaffold to improve therapeutic angiogenesis. We fused bFGF to the Kringle4 domain (K4)…
Though separate studies on the individual properties of photovoltage and magnetoresistance (MR) have made much progress, work integrating the two phenomena into one kind of structure has not been reported so far. This study combines MR and lateral photovoltage (LPV) in a magnetic oxidized film Co 3 Mn 2 O deposited on…
A comprehensive theory of electron spin resonance (ESR) for a Luttinger liquid state of correlated metals is presented. The ESR measurables such as the signal intensity and the linewidth are calculated in the framework of Luttinger liquid theory with broken spin rotational symmetry as a function of magnetic field and…
The structure of the protein complex CysM-CysO from a new cysteine biosynthetic pathway found in the H37Rv strain of Mycobacterium tuberculosis has been determined at 1.53 A resolution. CysM (Rv1336) is a PLP-containing beta-replacement enzyme and CysO (Rv1335) is a sulfur carrier protein with a ubiquitin-like fold. C…
This letter reports the optical microscopy characterization of gold nanoparticle-doped zeolite L crystals prepared by applying two key techniques: laser ablation and crystallization inclusion. The former allowed the stable formation of Au NPs in the synthesis gel, while the latter permitted the encapsulation of Au NPs…
A series of novel coordination polymers [Ln(suc)(ox) 0.5 (H 2 O)] (Ln = Sm ( 1 ) and Tb ( 2 )); [Pr(suc)(ox) 0.5 (H 2 O) 2 ]·2H 2 O ( 3 ); and [KLn(suc) 0.5 (ox) 1.5 (H 2 O)]·H 2 O (Ln = Nd ( 4 ), Eu ( 5 ), Tb ( 6 ) and Gd( 7 )) have been synthesized by the reaction of nitrate salts of Ln(III) with succinic acid and o…
Eight coordination polymers, {[Cu(btr) 2 (H 2 O) 2 ](BF 4 ) 2 ·2H 2 O} n ( 1 ), {[Cu 5 (btr) 10 (SCN) 6 (BF 4 ) 4 ]·5H 2 O} n ( 2 ), {[Cu(btr) 2 (SCN) 2 ]·2H 2 O} n ( 3 ), {[Cu(btr) 2 (NO 3 ) 2 ]·H 2 O} n ( 4 ), {[Cu(btr) 3 ](ClO 4 ) 2 } n ( 5 ), {[Cd(btr) 3 ](ClO 4 ) 2 } n ( 6 ), {[Cd 3 (btr) 8 (H 2 O) 2 ](BF 4 ) 6 }…
The molecular mechanisms underlying cell wall biosynthesis are poorly understood. In this study, microscopic analysis showed that protoplasts generated a new cell wall within 48 h after transfer to a wall-regeneration medium. To identify genes related to cell wall biosynthesis in cotton, suppression subtractive hybrid…
We numerically investigate force structures in the packing of fine cohesive particles using the discrete element method. By changing the particle size and therefore the van der Waals force, the effect of cohesion on the normal contact force and the total normal force, which is the sum of the normal contact forces and…
The insulator-to-metal transition in hcp solid helium at high pressure is studied with first-principles simulations. Diffusion quantum Monte Carlo (DMC) calculations predict that the band gap closes at a density of 21.3 g/cm;{3} and a pressure of 25.7 terapascals, which is 20% higher in density and 40% higher in press…
The discovery and phase transition studies of four polymorphs of 2-(phenylamino)nicotinic acid are described in this report. The four polymorphs were crystallized from solution under different conditions. All polymorphs differ in the degree of conjugation of the two aromatic rings and thus are of conformational polymo…
Abstract In this paper we consider some cases of Sturm–Liouville problems with two singular endpoints at x = 0 and x = ∞ which have a simple spectrum, and show that the simplicity of the spectrum can be built into the definition of a Titchmarsh–Weyl m ‐function from which the eigenfunction expansion can be constructed…
BACKGROUND: Polyethylenimine (PEI) vectors are widely used in gene delivery because of their high transfection efficiency owing to a unique proton sponge effect. An increase in molecular weight increases transfection efficiency, but simultaneously results in increased toxicity. Therefore, the design and synthesis of n…
Hydrogen sulfide (H2S) is a very common odor nuisance which is best controlled by chemical or biological scrubbing. Under alkaline pH, the amount of H2S that can be solubilized in a scrubbing liquid increases significantly, and therefore, gas-liquid mass transfer limitations can be reduced. To date, biological scrubbi…
