“…Surface modification methods can be physical or chemical, and there are a variety of treatments available. Over the last few decades, these modification methods have been established with an emphasis on the surface incorporation of extra functionalities responsible for the growing increase of surface free energy (wettability) and tailored applications [25][26][27]. Such modifications should only affect the top surface area (tens of nm), which is essential for functional strength and at the same time to maintain integrity of the material.…”

Plant-based materials have found their application in the packaging with a yearly growing production rate. These naturally biodegradable polymers are obtained from renewable and sustainable natural resources with reduced environmental impact and affordable cost. These materials have found their utilization in fully-renewable plant-based packaging products, such as Tetra Pak®-like containers, by replacing commonly-used polyethylene as the polymer component. Poly(lactic acid) (PLA) is one of the representative plant-based polymers because of its eco-friendliness and excellent chemical and mechanical properties. In this work, a PLA surface was modified by various food additives, namely ascorbic acid (ASA) and fumaric acid (FA), using plasma-initiated grafting reactions in order to improve the surface and adhesion properties of PLA. Various analytical and microscopic techniques were employed to prove the grafting process. Moreover, the improved adhesion of the modified PLA foil to aluminum (Al) foil in a laminate configuration was proven by peel resistance measurements. The peel resistance of modified PLA increased by 74% and 184% for samples modified by ASA and FA, respectively, compared with untreated PLA.

“…This property decreases the absorption tendency of the CO 2 with HSLD temperature. In addition, with rise in temperature, viscosity of HSLD decreases due to weakening of cohesive force of HSLD 44 . This property of the HSLD is also responsible for decrease in CO 2 absorption 45 .…”

“…In addition, with rise in temperature, viscosity of HSLD decreases due to weakening of cohesive force of HSLD. 44 This property of the HSLD is also responsible for decrease in CO 2 absorption. 45 After the temperature of the HSLD reached 50 C, the amount of carbon dioxide in the HSLD remained unchanged, which indicates that the regeneration process is Actual CO 46 The boundary layer formation at higher CO 2 concentration, causes a shock wave of absorption which continues to rise after that.…”

As the population and living standard of human beings rises, energy requirement also increases rapidly. In developing country like India, a major part of energy requirement is fulfilled by thermal power-based plants. It generates pollutant gases and water vapor responsible for global warming and other environmental problems. To overcome these problems in controlled area, a continuous experimental investigation has been performed based on the hybrid solid-liquid desiccant (HSLD) containing CaCl 2 (0.33 M), lithium chloride (0.66 M), titanium dioxide (0.026 M), silicon dioxide (0.316 M), copper oxide (0.067 M) for dehumidification, and CO 2 removal from the atmospheric air. In addition, CO 2 removal capacity of HSLD has been performed from CO 2 + air mixture containing variable CO 2 to air as 0.33-5.46 (wt ratio). Present study suggest relative humidity of air is reduced from 75% to

“…Lin et al [24] used a new high melting point paraffin wax (HPW) and PDA to coat HMX to obtain litchi-like microcapsules, which can significantly reduce the impact sensitivity and friction sensitivity and improve the thermal stability. Kosareva et al [25] used supercritical CO 2 as an anti-solvent to obtain polymer-coated HMX particles. The results show that the polymers at less than 3 wt% content can precipitate on the surface of HMX crystal as globular islands, which can significantly reduce the impact sensitivity.…”

Molecular Dynamics Simulation of β-HMX Crystal Morphology Induced by Polymer Additives

To simulate the crystal morphology of β-HMX crystallized in the presence of different polymer additives in the solution, a modified attachment energy model was used to simulate the crystal morphology of β-HMX recrystallized in PVA-DMSO solution when the mass fractions of PVA were 0.5%, 1%, 3%, 5%, and 10%, respectively. When the mass fraction of additive was 10%, the simulation results were in good agreement with the experiment. Molecular dynamics simulations were performed on the solution systems of different types of polymer additives to predict the morphology of β-HMX crystals. In addition, the effect of water on the crystal morphology of β-HMX was studied, and the effect of additive PVA on the solute and solvent diffusion ability during crystal crystallization was studied. The simulation results have certain reference significance in the crystallization process of β-HMX under additive conditions.
