AIMS To report the clinical outcome of infectious keratitis managed after doing 10% KOH mount of corneal smears and reporting done by an ophthalmologist in the secondary eye care centre in South India. METHODS 103 consecutive cases of microbial keratitis were studied. Inclusion criteria were presence of corneal infiltrate on slit lamp biomicroscopy. An ophthalmologist carried out microbiologi...

This paper reports the first investigation of the dependence of AC electro-osmosis (ACEO) on the solution chemistry. It is argued that classical dilute-solution theory breaks down in ACEO, since the large applied voltage leads to ion crowding near the electrode surfaces. A modified theory is proposed with steric effects (finite ion sizes) and a charge-dependent viscoelectric effect, which predi...

Schistosomiasis in pregnancy may cause low birth weight, prematurity and stillbirth of the offspring. The placenta of pregnant women might be involved when schistosome ova are trapped in placental tissue. Standard histopathological methods only allow the examination of a limited amount of placental tissue and are therefore not sufficiently sensitive. Thus, placental schistosomiasis remains unde...

BACKGROUND Molluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution. METHODS/DESIGN The study design is a double-blind, randomized clini...

Anisotropic etching of silicon in potassium hydroxide (KOH) is an important technology in micromachining. The residue deposition from KOH etching of Si is typically regarded as a disadvantage of this technology. In this report, we make use of this residue as a second masking layer to fabricate two-layer complex structures. Square patterns with size in the range of 15–150 μm and gap distance of ...

Unique room temperature-formed iron-doped nickel hydroxide on Ni foam as a 3D electrode in alkaline electrolyte offers fast gas dissipation, a high number of active sites and a high oxidation state of Ni for an improved oxidation ability for the oxygen evolution reaction (OER), which delivers an OER current density of 100 mA cm-2 at an overpotential of 0.312 V and 96.3% retention after 100 h at...

Sustainable porous carbons have been prepared by chemical activation of hydrothermally carbonized polysaccharides (starch and cellulose) and biomass (sawdust). These materials were investigated as sorbents for CO2 capture. The activation process was carried out under severe (KOH/precursor=4) or mild (KOH/precursor=2) activation conditions at different temperatures in the 600-800oC range. Textur...

Sustainable synthesis schemes for the production of porous carbons with appropriate textural properties for use as supercapacitor electrodes are in high demand. In this work a greener option to the widely used but corrosive KOH is proposed for the production of highly porous carbons. Hydrochar products are used as carbon precursors. It is demonstrated that a mild alkaline potassium salt such as...
