We present a versatile systematic two-bead-per-monomer coarse-grain modeling strategy for simulating the thermomechanical behavior of methacrylate polymers at length and time scales far exceeding atomistic simulations. We establish generic bonded interaction parameters via Boltzmann inversion of probability distributions obtained from the common coarse-grain bead center locations of five differ...

Immunodetection of human IgG anti-Toxocara canis was developed based on ELISA and on the use of polysiloxane/polyvinyl alcohol (POS/PVA) beads. A recombinant antigen was covalently immobilized, via glutaraldehyde, onto this hybrid inorganic-organic composite, which was prepared by the sol-gel technique. Using only 31.2 ng antigen per bead, a peroxidase conjugate dilution of 1:10,000 and a serum...

The often-encountered problem of disrupting bacteria for the purpose of extracting soluble protein has generated various methods. Many require specialized equipment. Very often, especially during preliminary studies, investigators need a simple, fast, and inexpensive method for cell disruption that preserves biological activity. This paper compares some simple and inexpensive methods for cell d...

We present an experimental method based on video microscopy to perform nanometer scale position detection of a micrometer bead in the direction along the propagation of the detection light. Using the same bead for calibration and detection significantly improves the in depth resolution in comparison to video microscopy methods from literature. This method is used together with an optical trap t...

Abstract Glass beads excavated from Nanhai I shipwreck were investigated with scanning electron microscopy energy dispersive spectrometer (SEM–EDS), Raman spectroscopy, multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) and X-ray diffraction (XRD). Dating back to the Southern Song Dynasty, these help study Chinese maritime trades during twelfth–thirteenth century. The bead...

The weight lightening of electric vehicles’ power battery box not only improves the mileage but also extends service life battery, while in practice design lightweight shall sacrifice its strength for safety reason. Herein, three materials including glass fiber composite, carbon and metal steel are used to develop same their strengths simulated. results show that sheet molding compound (SMC, a ...

The glass bead making furnace of the Masaga Glass Guild in Bida, Niger State Nigeria was evaluated comparison to those Ghana (Krobo) and India (Firozabad); it discovered that falls short an efficient system for sustainable work should facilitate appreciable productivity. Furthermore, is not built with refractory bricks, implying has a life span; operated by hand-worked traditional cloth bellows...
