DISODIUM CALCIUM DINICKEL(II) BIS[DIPHOSPHATE(V)] DECAHYDRATE

Disodium calcium dinickel(II) bis[diphosphate(V)] decahydrate

In the title KUKUI NUT BODY CREAM compound, Na2CaNi2(P2O7)2(H2O)10, there are two distinct P-atom sites, each tetrahedrally coordinated by four O atoms.The resulting phosphate tetrahedra link through a common O atom, forming a [P2O7]4− diphosphate unit.The Ni—O coordination is square pyramidal with four O atoms from two diphosph

Practicability analysis of hydraulic support design system for steeply dipping coal seam inclined pseudo inclined working face

In order to solve the problems of ignoring multi-dimensional load characteristics, cumbersome modeling process and long design cycle in the design process of hydraulic support in steeply dipping angle coal seam, combined with the load characteristics of hydraulic support in large dip angle pseudo-inclined working face, the design system of large di

Maximally PCB-Space-Saving Hybrid Integration of Millimeter-Wave and Microwave Antennas for 5G and B5G Smartphones

This paper proposes a simple, low-cost, and practical hybrid integration design of a 5G FR2 millimeter-wave antenna module based on a thin flexible printed circuit (FPC) and a 5G FR1 microwave antenna based on a metal frame to maximally save precious printed circuit board (PCB) space for more competitive 5G and beyond 5G (B5G) smartphones.The thin
