Aluminized explosives are widely used in military applications. However, the easy agglomeration of aluminum (Al) powder and its high ignition temperature greatly hinder reaction nano (n-Al) process explosion, thus affecting combustion explosion aluminum-containing explosives. In present study, copper (Cu) coated n-Al composite particles were introduced into aluminized explosives, Cu ball-milled octogen (HMX) energetic microspheres prepared via droplet microfluidic technology using binder....

In recent years, the demand for dry bulk cargo trade has increased, and scheduling pressure on ports is increasing daily. The most effective cost-effective way to alleviate of port management rapidly optimize overall different resources. Channel vessel berth–yard loading unloading operations are usually regarded as independent operations; however, plans that meet needs comprehensive can only be effectively developed through integrated multiple Therefore, from perspective operation,...

In order to improve the energy output consistency of 3, 3′-diamino-4, 4′-azoxyfurazan (DAAF) in new insensitive booster and safety efficiency preparation process, a continuous system DAAF from synthesis spherical coating was designed established this paper, which combined ultrasonic micromixing reaction with microdroplet globular template. rapid stage, microfluidic mixing technology used synergistically strengthen uniform mass transfer between raw materials ensure uniformity particle...

Near infrared (NIR) and mid-infrared (MIR) spectroscopy were investigated to predict iron zinc contents in powdered milk. A hybrid variable selection method, namely, uninformative elimination (UVE) combined with successive projections algorithm (SPA), was applied select the most effective wavenumber variables from full 2756 NIR 3727 MIR variables, respectively. Finally, 18 selected for content prediction, 17 12 prediction. The obtained input into partial least-squares (PLS)...

Energetic materials pose challenges in preparation and handling due to their contradictory properties of high-energy low-sensitivity. The emergence co-crystal explosives is a new opportunity change this situation. If the explosive coated into spherical particles with uniform particle size distribution, contradiction can be further reduced. Therefore, binder-coated hexanitrohexaazaisowurtzitane/2,4,6-trinitrotoluene (CL-20/TNT) microspheres were prepared by droplet microfluidic technology...

The aggregation of nano-aluminum powder seriously hinders the energy release aluminized explosives. This study developed a strategy using droplet microfluidic technology to prepare HMX/15 ​wt% n-Al/2 (NC and F2604) high-energy microspheres systematically studied effects different binders on morphology (i.e., roundness) dispersion properties microspheres. Moreover, it investigated thermal decomposition, mechanical sensitivity, combustion performance TG, differential scanning calorimetry...

Much attention has been paid to the coating of energetic materials improve their properties. However, present technology drawbacks, and it fails meet requirements engineering applications. In this study, observation toad spawning process gave an idea for efficient preparation millimeter-sized coated granules by directly using unrefined HMX. technique, device was cheaper were simpler. The mechanism formation curing studied. its formula continuously optimized during exploration process....

As maritime transportation develops, the pressure of port traffic increases. To improve management ports and efficiency their operations, vessel scheduling must be optimized. The problem can divided into channel berth allocation. We considered complex in a restricted allocation problem, combined model that considers carbon emissions was developed. This should reduce waiting times, quality loading unloading service, meet requirements “green” shipping, overall safety ports. An adaptive,...

Ammonium perchlorate (AP), which is the most commonly used oxidant in composite propellants, plays a vital role combustion performance of propellants. In this work, by coating AP surface with self-assembled layer gallic acid (GA) and transition metal ions (Cu2+ or Fe3+) then connecting it 1H,1H,2H,2H-perfluorodecyltrichlorosilane (PDTS) layer, AP@GA-M@PDTS (M = Cu2+ was successfully prepared. Molecular dynamics simulation calculations show that GA have good binding ability. At same time,...

Abstract Background Cardiovascular disease (CVD) and colon cancer incidence are known to be closely related dietary factors. This article evaluated effects of krill oil (KO) on serum lipids hyperlipidemia rats human cells (SW480). Serum fed with high fat diet (HFD) different doses KO were measured by automatic analyzer. Effect viability was determined methyl thiazolyl tetrazolium (MTT) assay. Results Except for higher dose group, body weights decreased significantly. Total cholesterol (TC),...

A class of Pt(IV)-PROTAC complexes was designed and synthesized with dual aims inducing DNA strand damage inhibiting repair. These showed good antiproliferative activity against a range cancer cell lines. Enhanced intracellular uptake platinum PROTAC observed. Multiple mechanisms action were identified, including the induction damage, disruption repair, activation mitochondrial-dependent apoptosis. One Pt(IV)-PROTACs, CW-2, excellent antitumor in xenograft mouse model. results suggest that...

To explore the impact mechanisms of China’s low-carbon pilot policies on urban carbon emissions, this paper employs propensity-score-matched difference-in-differences (PSM-DID) methodology, in conjunction with a dynamic marginal effect analysis, to examine through which policies, initiated three phases at disparate points time, influence emissions. The analysis is based panel data from 2009 2020. case demonstrates that have had considerable positive reduction Improving efficiency energy use...

Tribo-electrostatic separation is a promising method for effectively utiliing low-grade magnesite resources by removing quartz and improving the grade of magnesite. To determine charge-to-mass ratios pure quartz, triboelectric measurement system was employed, laboratory tribo-electrostatic used to separate The results showed that maximum difference in ratio between particles observed after friction with polyvinyl chloride. recovery increased temperature initially increasing voltage, feed...

In the traditional and extended shipboard operation human reliability analysis (SOHRA) model, error-producing condition (EPC) is critical. The weight proportion of each EPC in one specific task are often determined by experts’ judgments, including most modified versions. Due to this subjectivity, result recommended safety measures may not be as accurate they should be. This study attempts narrow gap proposing a novel approach, combination SOHRA, entropy method, TOPSIS model. method employed...
