Abstract:

Introduction. The high decorative properties and durability of marble determine its wide application in many areas of construction. Natural marble with fracturing is developed for the production of crushed stone of various fractions and micro calcite. The quality of the resulting commercial crushed stone is largely determined by screening operations. One of the quality characteristics is the content of pulverized and clay particles, which reduce the ability of the material to adhere to the binder. Dry screening often fails to achieve the required quality, and the use of wet screening increases

Abstract:

Enzyme immobilization techniques are widely researched due to their wide range of applications. Polymer–protein core–shell nanoparticles (CSNPs) have emerged as a promising technique for enzyme/protein immobilization via a self-assembly process. Based on the desired application, different sizes and distribution of the polymer–protein CSNPs may be required. This work systematically studies the assembly process of poly(4-vinyl pyridine) and bovine serum albumin CSNPs. Average particle size was controlled by varying the concentrations of each reagent.

Abstract:

Abstract The measurement of urine albumin now has a well-established role in the monitoring of patients with diabetes mellitus. We have developed a particle-enhanced immunoturbidimetric inhibition assay for urine albumin on the Dade aca® analyzer. The inhibition approach removes any of the potential antigen excess difficulties that could be expected from the wide clinical range of urine albumin, but retains the sensitivity advantages of latex-enhanced immunoturbidimetry. Human serum albumin (HSA) is covalently attached to 40-nm poly(chloromethyl)styrene-modified latex particles. This reagent,

Abstract:

Recovering residual oil reserves and reducing the level of water cut in produced wells at minimal cost are urgent tasks for mature fields. In such conditions, the use of tertiary methods of reservoir stimulation is relevant, among which a significant share is occupied by chemical methods of enhanced oil recovery. The principle of using flow diverting technologies is to supply small rims of chemical reagents to the reservoir through the reservoir pressure maintenance system, aimed at reducing the permeability of water-flushed zones by installing a waterinsulating barrier in them and redirecting

According to visual observations, the ratio ranges from 1 to 3 mmol/g; otherwise the suspensions are stable. By measuring the sedimentation rate and particle size distribution, the most extensive flocculation was found to be from 1.7 to 2.3 mmol/g.

Abstract:

A key aspect of microfluidic processes is their ability to perform chemical reactions in small volumes under continuous flow. However, a continuous process requires stable reagent flow over a prolonged period. This can be challenging in microfluidic systems, as bubbles or particles easily block or alter the flow. Online analysis of the product stream can alleviate this problem by providing a feedback signal. When this signal exceeds a pre-defined range, the process can be re-adjusted or interrupted to prevent contamination. Here we demonstrate the feasibility of this concept by implementing a

Abstract:

Motorcycle theft cases in Malaysia have increased quite significantly with more motorcycles were reported stolen every day. In many cases, criminals had removed the components they only required and disposed the remaining parts into various sources of water. Unfortunately, the evidence recovered underwater was thought not to have forensic value with regards to fingermark recovery. This study aimed to determine the survivability of the latent fingermarks submerged in various water environments. Latent fingermarks were deposited on metal parts of motorcycle and submerged into four aquatic enviro

Abstract:

Grouting technology is an important method of ground reinforcement and can effectively improve the stability of engineering rock mass. During overburden isolated grouting in coal mines, the influence of unexpected fractures may lead to substantial grout leakage, resulting in ineffective grouting. The existing natural sedimentation sealing method is mainly applicable to small fractures and low grout flow, while the chemical-reagent rapid-sealing method can cause grouting channel blocking, making it less suitable for overburden isolated grouting. This paper proposes a “capsule” sealing method, d

Abstract:

Vanadium is a significant metal, and its derivatives are widely employed in industry. One of the essential vanadium compounds is vanadium pentoxide (V2O5), which is mostly recovered from titanomagnetite, uranium–vanadium deposits, phosphate rocks, and spent catalysts. A smart method for the characterization and recovery of vanadium pentoxide (V2O5) was investigated and implemented as a small-scale benchtop model. Several nondestructive analytical techniques, such as particle size analysis, X-ray fluorescence (XRF), inductively coupled plasma (ICP), and X-ray diffraction (XRD) were used to dete

Abstract:

Microfluidics, as one of the most valuable analytical technologies of this century, has played an important role in various fields. Particularly, out-of-channel microfluidics, often referred to as open microfluidics (OMF) has recently drawn wide research attention among scholars for its great potential in convenient manual intervention. Much recent research has been geared toward bare droplets and particle-armed droplets (namely liquid marbles, LMs), which could serve as independent systems in OMF. Their versatile applications include but are not limited to nanomaterials preparation, energy ha

Abstract:

Special physical and chemical properties of nanoscale zero valent iron (nZVI), such as small particle size and high reactivity, make it a good choice as a remediation agent. nZVI is widely used in the remediation of various contaminants, including heavy metals and persistent organic pollutant. However, the immobilization of nanoparticles in porous medium limits the application in soil environmental remediation. Foam instead of water is used as the carrier of nanoparticles in in-site soil remediation process, which is a new idea, to improve sweep efficiency of nanoparticles. In this paper, the

Abstract Worldwide, lung cancer and colon cancer are the most frequently diagnosed cancers with high mortality. Targeted therapy, including small molecule inhibitors and monoclonal antibodies of various oncogenic proteins, has improved survival, but the development of resistance remains a significant issue. TP53 is a critical tumor suppressor gene and loss of function occurs in over 50% of all human cancers. In lung and colon cancer, the evolutionary conserved codons of the tumor suppressor gene TP53 are frequently mutated. Among the range of mammalian species, elephants develop less cancer th

High-throughput production is vital to achieve cost-effective proton exchange membrane fuel cells (PEMFCs) at scale1. The high-volume mass production of PEMFCs using industrial manufacturing machinery may however introduce unwanted material in the final product due to the wear and tear of the machinery. As an example, roll-to-roll processes applied to the manufacture of catalyst coated membrane (CCM) generally use Fe alloys such as stainless steel2 components that could release fine metallic particles or related debris that may affect the product quality3,4.

A criterion used to evaluate the efficiency of converter matte foam separation into nickel and copper concentrates is a selectivity index based on the total recoveries of metals into target concentrates that in turn defines their cumulative impurities (secondary metals) content. In addition to various factors (meeting density and reagent flow charts, comminution parameters, etc.), the time of preceding cooling of ingots is also known to have a substantial effect on the process of converter matte separation at commercial scale.
