In current work aqueous solution of potassium prolinate (KPr) and potassium prolinate blended with 2-amino-2-methyl-1-propanol (AMP) have been exploited in order to investigate the possible use of these salts of amino acid blended with alkanolamine for CO2 capturing. The equilibrium solubility d...

This project study involves the techno-economic assessment of two new advanced configurations for amine-based carbon dioxide capture from a pulp mill. The newly proposed advanced configurations include advanced rich amine four split (ARA4S), and advanced rich amine three split with desorber inte...

Rate constants for the reaction of aqueous 2-amino-2-methyl-1-propanol (AMP)/ammonia (NH3) solutions with SO2 were determined by measuring their SO2 absorption rates. The SO2 absorption characteristics of 30 wt% AMP solutions with added NH3(1, 3, and 5 wt%) were investigated using a stirred-cell...

This study reports the investigation of carbon dioxide (CO2) absorption into an amine blend solution of 2-amino-2-methyl-1-propanol (AMP) and piperazine (PZ). The reaction in the liquid phase between CO2 and the amines were qualitatively and quantitatively monitored by Fourier Transform Mid-Infr...

The gas–liquid two-phase flow and mass transfer performance of CO2 absorption into 2-amino-2-methyl-1-propanol (AMP) with ethylene glycol (EG) non-aqueous solution in a microchannel were investigated under different gas–liquid two-phase flow rates and AMP concentrations. A new correlation was ...

The aim of this study was to find a solvent to replace N-methyl-2-pyrrolidone (NMP) in CO2 absorption systems containing the amine 2-amino-2-methyl-1-propanol (AMP), in order to reduce the health risks associated with handling, as NMP is reproductively toxic. Seven organic solvents were investig...

In a light microscopic study the ferric ion-ferrocyanide staining of the squid giant axon was investigated. In other neurons this stain is known to indicate excitable membranes with high sodium channel density, such as the node of Ranvier or the initial segment. In the squid the stain reacted in...

BACKGROUND: Allergic conjunctivitis is the most common atopic disease affecting the eye. To study the pathophysiology and effectiveness of antiallergic drugs, it is necessary to develop animal models that closely mimic human allergic conjunctivitis. OBJECTIVE: The study was performed to develop ...

We aimed to investigate the molecular mechanisms underlying the renal wasting of Na+, K+, Ca2+, and Mg2+ in gentamicin (GM)-treated rats. Male Wistar rats were injected with GM (40 or 80 mg/kg/day for 7 days, respectively; GM-40 or GM-80). The expression of NHE3, Na–K-ATPase, NKCC2, ROMK, NCC, ...

Ovarian tissue cryopreservation is a promising technique for fertility preservation in young female cancer patients and efforts have been made to improve its effectiveness. During cooling and thawing, sodium ions significantly contribute to the ‘solute effect’ that plays a major role in disrup...

The medical literature is replete with the maxim ‘primum non nocere’, cautioning health care providers to avoid doing any harm to human subjects in their delivery of medical care. Sodium hypochlorite (NaOCl) is a well-established irrigant for root canal treatment because of its antimicrobial a...

Acquisition of the membrane and genome encapsidation is an important step in the replication of enveloped viruses. The biogenesis of the poxviral primary membrane and the core as well as the mechanisms of their maturation are poorly understood. Using RNA interference approach, we demonstrate tha...

Trichosporon spp. have been increasingly recognized as an important pathogen of invasive and disseminated infections in immunocompromised patients. These species are prone to form biofilms in medical devices such as catheters and prosthesis, which are associated with antifungal resistance and th...

In this study, the response to ionsing radiation of the normoxic polymer gel dosimeter comprising tetrakis (hydroxymethyl) phosphonium chloride (THPC) with methacrylic acid (MAA) and gelatin, named MAGAT, has been investigated. Using magnetic resonance imaging (MRI), the R2-dose response or chan...

This work reports the design and synthesis of side-chain amino acid containing cross-linked polymer gels with high mechanical strength. The Boc-leucine methacryloyloxyethyl ester (Boc-Leu-HEMA) has been polymerized by reversible addition-fragmentation chain transfer (RAFT) polymerization to obta...

The research investigates the efficiency of biochar to eliminate an emerging contaminant, flame retarding chemical, a.k.a. Tetrakis (Hydroxymethyl) Phosphonium Chloride (THPC) from water. The THPC, which is a water-soluble, organophosphorus salt, is mainly used by textile industries as a flame r...

The genotoxicity of effluents collected from a conventional 5-stage softwood kraft pulp bleaching process was studied in Chinese hamster ovary (CHO) cells in vitro. Spent liquor from the first chlorination stage (C/D), where elemental chlorine and chlorine dioxide had been used in equal proporti...

A new process for β-amino acid 1 cyclodehydration to β-lactam 2 using methanesulfonyl chloride/ sodium bicarbonate is described.

Several commercially available hydroxymethylaryl resins were converted to their corresponding chloromethyl analogs by simple treatment with methanesulfonyl chloride and Hunig's base in DMF at 25 °C over 3 days. This mild method gave quantitative conversions as determined by elemental analy...

Methanesulfonyl chloride (MSC) forms a room temperature ionic liquid with AlCl3. The electrochemical properties of vanadium pentoxide (V2O5) films prepared by the sol–gel route were studied in this electrolyte. As a potential cathode, sodium is reversibly intercalated into the V2O5 film up to a...
