A dendrimer amphiphilic polymer (A-D-HPAM) was synthesized by aqueous solution polymerization of acrylic acid (AA), acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic (AMPS), hydrophobic monomer cetyl dimethyl allyl ammonium chloride (DMCAAC-16), and skeleton GA1.0, using persulfate sodium bisulfite as initiators. The chemical structure A-D-HPAM was, respectively, analyzed Fourier transf...

a r t i c l e i n f o Identity disclosure is one of the most serious privacy concerns in today's information age. A well-known method for protecting identity disclosure is k-anonymity. A dataset provides k-anonymity protection if the information for each individual in the dataset cannot be distinguished from at least k − 1 individuals whose information also appears in the dataset. There is a fl...

The most common anionic surfactants in the formulation of detergents are Linear Alkylbenzene Sulfonates (LAS), with an sulfonate head group and a hydrophobic alkylbenzene tail group. two primary synthetic detergents, together sodium laureth sulphate, have been around for quite some time may be found many personal-care items such as shampoos, soaps, toothpaste, laundry detergent. LAS is relative...

King 2, one of the oldest clusters in Milky Way, with an age $\sim$ 6 Gyr and distance $\sim 5700$ pc, has been observed UVIT payload on \textit{ASTROSAT}. With membership information derived from {\it Gaia} EDR3, cluster is found to have 39 blue straggler stars (BSSs). We created multi-wavelength spectra-energy distributions (SED) all BSSs. Out 10 UV detected BSSs, bright ones fitted double co...

We report the discovery of first hot subdwarf B (sdB) star with a massive compact companion in wide ( P = 892.5 ± 60.2 d) binary system. It was discovered based on an astrometric solution provided by Gaia mission Data Release 3. performed detailed analyses spectral energy distribution (SED) as well spectroscopic follow-up observations and confirm nature visible component sdB star. The is invisi...

Nano-micro calcium carbonate has a small particle size, uniform distribution, and good dispersion performance, offering great research value development prospects. It been widely used as filler material for rubber, paper, ink, pigments, coatings. Developing an efficient controllable approach to preparing nano-micro with adjustable morphology size significant economic environmental benefits. Thi...
