Ni/Pd co-modified graphene hydrogen storage materials were successfully prepared by a solvothermal method using NiCl2·6H2O and Pd(OAc)2 and reduced graphene oxide (rGO). By adjusting the hydrothermal temperature, Pd–Ni is successfully alloyed, and the size of the obtained nanoparticles is uniform. The electronic structure of Pd was changed by alloying, and the center of the D-band moved down, which promoted the adsorption of hydrogen. The NiPd-rGO-180 sample, in which 180 represents the solvothermal temperature in centigrade (°C), has the highest hydrogen storage capacity of 2.65 wt% at a moderate condition (RT/4MPa). The excellent hydrogen storage performance benefits from the synergistic hydrogen spillover effect of Pd–Ni bimetal. The calculated hydrogen adsorption energies of Ni2Pd2-rGO are within the ideal range (−0.20 to −0.60 eV) of hydrogen ads/desorption; however, the introduction of substrate defects and the cluster orientation alter the hydrogen adsorption energy. This work provides an effective reference for the design and optimization of carbon-based hydrogen storage materials.

The rapid development of technology in today's world has had a major impact on store performance in all areas of business, both in trading and service companies. In maintaining more advanced competitiveness, stores must continue to develop technology, another thing that needs to be considered in making the company more advanced is the relationship with customers which is also an important thing to always maintain. To manage good relationships with prospective customers and customers, the company uses Customer Relationship Management (CRM). CRM is a service to customers that is personal, to provide a consistent experience, so that it can provide customer satisfaction, and also get good relationships in the long term. By implementing a good CRM, stores will be easier to interact with potential customers and customers and provide information according to their needs. Customers can also get the information they need more quickly and easily. The Customer Relationship Management (CRM) System for Web-Based Information Services at Yusni's Clothing Store can make it easier for consumers who are in the village of base lunang, sub-district of kualauh leidong, district of Labuhan Batu Utara.

The development of efficient hydrogen storage materials is crucial for advancing hydrogen-based energy systems. In this study, we prepared a highly innovative palladium-phosphide-modified P-doped graphene hydrogen storage material with a three-dimensional configuration (3D Pd3P0.95/P-rGO) using a hydrothermal method followed by calcination. This 3D network hindering the stacking of graphene sheets provided channels for hydrogen diffusion to improve the hydrogen adsorption kinetics. Importantly, the construction of the three-dimensional palladium-phosphide-modified P-doped graphene hydrogen storage material improved the hydrogen absorption kinetics and mass transfer process. Furthermore, while acknowledging the limitations of primitive graphene as a medium in hydrogen storage, this study addressed the need for improved graphene-based materials and highlighted the significance of our research in exploring three-dimensional configurations. The hydrogen absorption rate of the material increased obviously in the first 2 h compared with two-dimensional sheets of Pd3P/P-rGO. Meanwhile, the corresponding 3D Pd3P0.95/P-rGO-500 sample, which was calcinated at 500 °C, achieved the optimal hydrogen storage capacity of 3.79 wt% at 298 K/4 MPa. According to molecular dynamics, the structure was thermodynamically stable, and the calculated adsorption energy of a single H2 molecule was −0.59 eV/H2, which was in the ideal range of hydrogen ad/desorption. These findings pave the way for the development of efficient hydrogen storage systems and advance the progress of hydrogen-based energy technologies.

The field experiment entitled “Impact of Nitrogen and Silicon application on yield and relative economics of transplanted rice under temperate conditions” was conducted at Agronomy Research Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir during Kharif seasons 2014-2015. The soil of the experiment was silty clay loam in texture, neutral in reaction with medium available nitrogen (442.88kg ha-1), phosphorus (9.3kg ha-1), potassium (221.60kg ha-1) and low available silicon (280.23kg ha-1). The experiment was laidout in Factorial Randomized Completely Block Design assigning combinations of three nitrogen levels viz. 120, 150 and 180N kg ha-1 and four silicon levels viz. Control, 5%, 10% and 15% Si with four replications. The results revealed that higher grain yield (76.00q ha-1), straw yield (93.97q ha-1) and harvest index (44.84%) were recorded with 120Nkgha-1. So far as silicon levels are concerned, 15%Si observed higher grain yield (76 q ha-1), straw yield (93.97 q ha-1) and harvest index (44.84%). Relative economics revealed that 120Nkgha-1 with 15%Si realized higher benefit cost ratio (Rs. 2.12).
