Out with Acetonitrile: Water-assisted Accelerated-Aging Synthesis of CuI-Pyrazine Hybrid Materials

CuI and pyrazine form three hybrid materials, [(CuI)2(pyrazine)] (Yellow), [(CuI)2(pyrazine)2] (Orange), and [(CuI)(pyrazine)] (Red). In this work, Red was prepared using a green synthetic method, water-assisted accelerated-aging synthesis, for the first time. The syntheses were performed under ambient conditions with only water and no organic solvents. Depending on the reaction conditions, the other two hybrid materials can be formed as well: Orange was formed immediately after dry grinding CuI and pyrazine, while Yellow can be formed from Red and excess amount of CuI at mildly elevated temperatures. The impacts of temperature and types and amounts of liquid added to the aging mixture on the accelerated-aging synthesis were studied, and mechanisms of the synthesis and interconversions between the three CuI-pyrazine hybrid materials were proposed.

Impact of the New Textile Policy and Textile Waste Management System in India and a Move towards Sustainable Management

Textile Industry is a very old and second most growing industry in India . It is also the second largest producer after China. Textile manufacturing process produces humongous amount of chemical toxic and utilizes excess amount of water which can serve a rural village for a year , Textile industry has contributed to climate change and air and water pollution ,today the world is adopting sustainable methods in textile sector to reduce their emission followed by Textile waste , India produces 1 million tonnes of textile waste per years where the household also amounts to good amount of it . Many of brands have to burn their product because of less sell and many because of over production which not only results in lost but also contributes to carbon footprints. Countries have started to utilize alternative textiles like pineapple leaves instead of cotton to reduce soil erosion , followed by man made fabric , use of plastic for making clothes. We need to introduce PPP model to collect waste and adjoin skill development programme and entrepreneurship for better sustainable economical growth and proper management.

Synergetic effect of the surface ligand and SiO2 driven photoluminescence stabilization of the CH3NH3PbBr3 perovskite magic-sized clusters

Zero-dimensional Perovskite Magic-size Clusters play crucial roles in understanding and controlling nucleation and growth of semiconductor nanoparticles. However, their metastability behavior is a critical hindrance for reliable characterizations. Here, we report the first demonstration of using an excess amount of surface ligand and SiO2 as novel passivation for synthesizing the magic-sized clusters (MSCs) by the Ligand-assisted reprecipitation method. A synergetic effect between an excessed surface ligand and SiO2 inhibits the protonation and deprotonation reaction between amine-based and acid-based ligand, leading to enhanced PL stability. The obtained CH3NH3PbBr3 PMSCs/SiO2 retain 70% of its initial emission intensity in ambient conditions for 20 days. This passivation approach opens an entirely new avenue for the reliable characterizations of CH3NH3PbBr3 PMSCs, which will significantly broaden their application for understanding and controlling nucleation and growth of semiconductor nanoparticles.

DNA dynamics and computation based on toehold-free strand displacement

We present a simple and effective scheme of a dynamic switch for DNA nanostructures. Under such a framework of toehold-free strand displacement, blocking strands at an excess amount are applied to displace the complementation of specific segments of paired duplexes. The functional mechanism of the scheme is illustrated by modelling the base pairing kinetics of competing strands on a target strand. Simulation reveals the unique properties of toehold-free strand displacement in equilibrium control, which can be leveraged for information processing. Based on the controllable dynamics in the binding of preformed DNA nanostructures, a multi-input-multi-output (MIMO) Boolean function is controlled by the presence of the blockers. In conclusion, we implement two MIMO Boolean functions (one with 4-bit input and 2-bit output, and the other with 16-bit input and 8-bit output) to showcase the controllable dynamics.

Comparison of Acid-neutralizing capacity of antacids in Erbil City

Background and objective: Antacids are basic substances that can neutralize hydrochloric acid and reduce gastric acidity. They are over the counter drugs used to treat dyspepsia. The most commonly used antacids are sodium bicarbonate, magnesium hydroxide, aluminum hydroxide, and calcium carbonate. This study aimed to evaluate the effectiveness of antacids that are commonly used in Erbil city by finding their acid-neutralizing capacity. Methods: The method for acid-neutralizing capacity was adapted from pharmacopeia. The samples were prepared by dissolving the antacid in an excess amount of hydrochloric acid, then neutralizing the excess acid with sodium hydroxide solution by doing back titration. The number of milliequivalents that are neutralized by the antacid is the acid-neutralizing capacity of the antacid. Results: Rennie® chewable tablet showed the highest acid-neutralizing capacity, followed by AntacidAwa and Maalux® plus. The lowest acid-neutralizing capacity was for the suspensions Gaviscon® and Enoxon®. Conclusion: Acid-neutralizing capacity is an easy and quick method to evaluate the efficacy of antacids. Different combinations of salts and concentrations can affect the acid-neutralizing capacity of the antacid. The higher the neutralizing effect of the antacid, the more effective the antacid is. Keywords: Acid-neutralizing capacity; Antacid; pH; Dyspepsia; Erbil.

Lorawan Based Smart Agriculture, Remote Sensing and Auto Watering System

The smart agriculture is the active process which helps farmers in getting overall yield. Many factors play a vital role in getting yield such as moisture /humidity of the soil, temperature, carbon monoxide on top layer of the soil. This project is undertaken in order to help farmers in increasing the quantity of product and gain. The sensors such as temperature, moisture, carbon and etc. Senses and provides the values and these measured values are then passed through the node where LoRa module and Arduino is present. These data are stored in the cloud and utilized whenever required. Simultaneously a water pump in connected and with the help of measured values, depending on the crop, the water is pumped. Water pumping is mainly dependent on the quantity of CO present on the top layer of the soil. If it is in excess amount, then water is overflowed such that CO on top layer of the soil which is not necessary will be removed. Parallelly the measured values are stored in cloud and utilized by soil testing centers for clearing the issues of the farmer. This helps in water usage reduction up to approximately 50% and helps farmer get good yield and profit.

DOES WORKING CAPITAL HAS AN IMPACT ON PROFITABILITY OF INDIAN STEEL INDUSTRY

Working capital has a major role in day to day business activities. It is simply defined as the excess amount of current assets over current liabilities. Working capital also means the fund which is needed for the operations which are taken place in a firm every day. So working capital is considered as a fund which revolves all the time. This revolving fund consists of continues conversion of cash and raw materials in to inventory, then inventory to sales or debtors and this debtors into cash or investment. The existing Working capital in the company is also commonly known as Net Working Capital or net current assets, is the excess if current assets over currentliabilities. But this is on a particular day i.e., 31st March’s position. While it is important to know whether the company really has correct level of WC which is required to them? For this purpose there is a need to find out the required working capital and its relation with the profitability. Thus, the research work has included measuring the impact of WC on profitability. Further there must be discussions with the accounting experts of the selected 10 steel companies to know what they feel about their desired level and actual level of working capital.
