Quantitative analysis of mechanically retentive ceramic bracket base surfaces with a three-dimensional imaging system.

Conclusion: Irregular bracket surface features showed the highest surface roughness values and unit bracket base surface area among ceramic brackets, which contributes to increased mechanically retentive bracket bonding strength. PMID: 23270384 [PubMed - as supplied by publisher]

As with many emerging technologies, it has hit significant hurdles. Recently in an unprecedented move, the UK's Information Commissioner's Office (ICO) – the government body responsible for GDPR and data privacy enforcement – launched an independent investigation into the use of facial recognition at London's King's Cross train station, after it was revealed that the general public were having their faces scan...

In this research, the hydrothermal method was used for synthesising cellulose acetate (CA) templated nanorods like CuS fibres using vegetable extract (Brassica oleracea var. italica). These extracts act as a reducing agent in the presence of CA. Surprisingly, when the same reaction was carried out in the absence of CA and broccoli extract, structural morphology disappeared and was found as agglomerated. In the presence of cellulose templated extract mediated CuS has revealed as nanorods like fibres and was confirmed by field emission scanning electron microscope analysis. Their crystallinity property of CuS nanoparticles (...

To sustained release of an anticancer drug, oxaliplatin (OX), a non-toxic and biocompatible nanocarrier based on bovine serum albumin (BSA) were synthesised by desolvation method and characterised using Fourier-transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM) and dynamic light scattering. The results showed that the BSA nanoparticles (BSANPs) with a mean magnitude of 187.9 ± 1.2 nm have spherical morphology with a smooth surface and a uniform distribution. Furthermore, OX was loaded onto the BSANPs and the loading was confirmed...

The silk fibroin, a biodegradable polymer from cocoons of Bombyx mori silkworm were extracted by employing a chemical-free High-Temperature High-Pressure method as a degumming route. Then followed by the regeneration process which was do...

However, fragility of these physical gels restricts their applicability where gels of higher mechanical strength are required. Herein, we have developed two different types of 2-D carbon nanomaterials viz. g...

Bidkar, Priyadarshi Satpati, Anirban Bhunia, Sunanda ChatterjeeAbstractThe widespread abuse of antibiotics has led to the use of antimicrobial peptides (AMPs) as a replacement for the existing conventional therapeutic agents for combating microbial infections. The broad-spectrum activity and the resilient nature of AMPs has mainly aggrandized their utilization. Here, we report the design of non-toxic, non-hemolytic and salt tolerant und...

In this study, an indium electrowinning process using a sulfate electrolyte on stainless steel, nickel, titanium, aluminum and copper (SS, Ni, Ti, Al and Cu) cathodes was investigated. Firstly, cyclic voltammetry carried out at 15 mV/s scanning rate and 25 °C temperature evaluated the suitability of electrolyte and the surface reactivity on different metal cathodes. Subsequently, indium was deposited using a current density of 25 A/m2 for 22 hours at 40 °C and pH 2.3. After electrowinning process, analysis of specific energy consumption (SEC), current efficiency (CE) morphological (SEM/E...
