A facile method for the synthesis of Zn2Al-borate and Mg3Al-borate layered double hydroxides (LDHs) with extremely high specific surface areas of 458.6 and 263 m(2) g(-1) and containing delaminated nanosheets is reported. To the best of our knowledge, this is the first report of LDH powders that still remain exfoliated on drying.

We demonstrated that analyzing the formed gels containing exfoliated nitrate or glycine intercalated layered double hydroxide (LDH) nanosheets in formamide using X-ray diffraction is a simple and reliable method for determining the delamination degree of LDHs in formamide, which shows many advantages compared to the common characterization technologies.

Healthy mobile phone users aged 18-30 y.o. provided exfoliated buccal cells samples from the right and left inner cheeks. A total of 2000 cells per subject were screened for the presence of micronuclei as a sign of genotoxic damage, according to the mobile phone use profile of each user.

We demonstrate the first example of exfoliated layered europium hydroxide (LEuH) composites with a fluorescent molecule that exhibit blue luminescence. Co-quenching in the solid state, blue emission (440 nm) in formamide, and green emission (514 nm) in water-formamide were found, for which delamination and swollen states account for the versatile luminescence behaviors.

A nanocomposite of colloidal graphene oxide (CGO) and polyaniline (PANI) was fabricated via in situ oxidation polymerization in the presence of CGO prepared via a modified Hummers method without a dopant, in which the graphene oxide was individually exfoliated. Its electrorheological properties and other physical characteristics were studied.

p-Phosphonic acid calix[4]arenes render high stability to exfoliated graphenes in water. These calix[4]arenes modified graphenes can be used as highly effective substrates to nucleate ultra-small Pd nanoparticles, which in turn serve as galvanic reaction templates for the generation of high density 2D arrays of Pt nanoparticles.

Inorganic arsenic (iAs) is a well-established carcinogen and human exposure has been associated with a variety of cancers including those of skin, lung, and bladder. High expression of transforming growth factor alpha (TGF-alpha) has associated with local relapses in early stages of urinary bladder cancer. iAs exposures are at least in part determined by the rate of formation and composition of...

INTRODUCTION Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. AIM The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by hist...

Immunoperoxidase methods using two antibodies were developed for detection and quantitation of DNA damage in single cells. A monoclonal antibody that recognizes 4-aminobiphenyl (4-ABP)-DNA adducts was initially tested on liver tissues of BALB/c mice treated with 4-ABP, then applied to the detection of adducts in oral mucosa and exfoliated urothelial cells of smokers and nonsmokers. Levels of 4-...
