Abstract The study examines whether loans from microfinance institutions (MFI) reduce poverty in Bangladesh drawing upon the nationally representative household panel with four rounds from 1997 to 2004. The effects of general microfinance loans and loans for productive purposes on income, food consu...

Paper and paper products are widely used without any antimicrobial efficacy in our everyday lives and thus can act as potential transporters of many diseases. Herein, we introduce antimicrobial activity to cellulose paper by presenting a tailored mussel-inspired strategy for the sustainable immobili...

Vibrational sum frequency generation (SFG) spectroscopy was utilized to distinguish different populations of water molecules within the electric double layer (EDL) at the silica/water interface. By systematically varying the electrolyte concentration, surface deprotonation, and SFG polarization comb...

Mn(3)O(4) nanoparticles with diameter ca. 10nm were synthesized by the forced hydrolysis of Mn(II) acetate at 80 degrees C. The X-ray diffraction (XRD), Fourier transform infra red (FT-IR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques were employed to ...

Specific ion effects (SIEs) are known to influence the acid/base behavior of silica and the interfacial structure of water, yet evidence of the effect of pH on SIEs is lacking. Here broadband vibrational sum frequency generation (SFG) spectroscopy was used to study SIEs on the water structure at the...

The industrial revolution in the 20th century led to the evolution of numerous anthropogenic pollutants. Biochar, solid residue obtained from the pyrolysis of naturally available biomass, has attracted the attention of researchers due to its ability to remove these pollutants through adsorption from...

Technical and social performances of an arsenic-removal technology—the sono arsenic filter—in rural areas of Bangladesh were investigated. Results of arsenic field-test showed that filtered water met the Bangladesh standard (<50 µg/L) after two years of continuous use. A questionnaire was administra...

'-methylene bisacrylamide (MBA). For instance, tensile strength and the toughness increased by more than 6 times and 10 times, respectively, upon replacing MBA with BF-Si in polyacrylamide hydrogel. Moreover, the hydrogels crosslinked with BF-Si exhibited a remarkably elevated level of swelling capa...

Here, we report a novel fabrication of a magnetic carbon nanotube-reduced graphene oxide-silver nanocomposite for the adsorption and simultaneous catalytic reduction of two environmental pollutants. Fe3O4 nanoparticles were grown and anchored onto the multi-walled carbon nanotube (CNT) first to gene...

'-methylene-bis(acrylamide) of approximately the same modulus demonstrated no self-healing at all. Similar improvement of self-healing properties and toughness in PAA-GOBC hydrogel has also been observed which demonstrated the universality of the crosslinker. This crosslinker-based approach to impro...

A recommendation system can assist the user to compose an understanding of requirements and propose informed decisions from a lot of complicated knowledge. Recommendation from an analysis of sentiments seems to be a great challenge as user-generated content is represented using human language in sev...
