Sonochemical synthesis of cerium oxide nanoparticles-effect of additives and quantum size effect.

Journal of colloid and interface science

Yin L, Wang Y, Pang G, Koltypin Y, Gedanken A.
PMID: 16290386
J Colloid Interface Sci. 2002 Feb 01;246(1):78-84. doi: 10.1006/jcis.2001.8047.

Cerium oxide (CeO(2)) nanoparticles were prepared sonochemically, by using cerium nitrate and azodicarbonamide as starting materials, and ethylenediamine or tetraalkylammonium hydroxide as additives. The additives have a strong effect on the particle size and particle size distribution. CeO(2) nanoparticles...

Si:P as a laboratory analogue for hydrogen on high magnetic field white dwarf stars.

Nature communications

Murdin BN, Li J, Pang ML, Bowyer ET, Litvinenko KL, Clowes SK, Engelkamp H, Pidgeon CR, Galbraith I, Abrosimov NV, Riemann H, Pavlov SG, Hübers HW, Murdin PG.
PMID: 23403570
Nat Commun. 2013;4:1469. doi: 10.1038/ncomms2466.

Laboratory spectroscopy of atomic hydrogen in a magnetic flux density of 10(5) T (1 gigagauss), the maximum observed on high-field magnetic white dwarfs, is impossible because practically available fields are about a thousand times less. In this regime, the...

PMID: 22103162
J Nanosci Nanotechnol. 2011 Aug;11(8):7222-5. doi: 10.1166/jnn.2011.4834.

We fabricated an radio frequency (RF) carbon nanotube field effect transistor (CNTFET) whose electrode shapes were standard RF designed ground-signal-ground (GSG)-type pads. The S-parameters measured from our RF CNTFET in the frequency range up to 6 GHz were fitted...

Gait difficulty, postural instability, and muscle weakness are associated with fear of falling in people with Parkinson's disease.

Parkinson's disease

Parkinsons Dis. 2012;2012:901721. doi: 10.1155/2012/901721. Epub 2011 Oct 05.

The present study aimed to examine the contribution of gait impairment, postural stability and muscle weakness to the level of fear of falling in people with Parkinson's disease (PD). Fifty-seven community-dwelling individuals with PD completed the study. Fear of...

Frequency stabilized coherent Brillouin random fiber laser: theory and experiments.

Optics express

Pang M, Bao X, Chen L, Qin Z, Lu Y, Lu P.
PMID: 24216939
Opt Express. 2013 Nov 04;21(22):27155-68. doi: 10.1364/OE.21.027155.

A coherent random fiber laser based on stimulated Brillouin scattering as gain and Rayleigh scattering as distributed feedback mirror was constructed. Its frequency is stabilized by a high finesse narrow-band Fabry-Perot interferometer (FPI) to select lasing frequency within the...

Fast response and highly selective sensing of amine vapors using a luminescent coordination polymer.

Chemical communications (Cambridge, England)

Detecting volatile amines is a significant topic in the quality control of food and medical diagnosis. We report the first Eu-coordination polymer (CP) as a sensory material for the detection of a class of amine vapors with high selectivity...

Basophil activation test with food additives in chronic urticaria patients.

Clinical nutrition research

Kang MG, Song WJ, Park HK, Lim KH, Kim SJ, Lee SY, Kim SH, Cho SH, Min KU, Chang YS.
PMID: 24527415
Clin Nutr Res. 2014 Jan;3(1):9-16. doi: 10.7762/cnr.2014.3.1.9. Epub 2014 Jan 27.

The role of food additives in chronic urticaria (CU) is still under investigation. In this study, we aimed to explore the association between food additives and CU by using the basophil activation test (BAT). The BAT using 15 common...

APOE and APOC1 gene polymorphisms are associated with cognitive impairment progression in Chinese patients with late-onset Alzheimer's disease.

Neural regeneration research

Zhou Q, Peng D, Yuan X, Lv Z, Pang S, Jiang W, Yang C, Shi X, Pang G, Yang Y, Xie H, Zhang W, Hu C, Yang Z.
PMID: 25206869
Neural Regen Res. 2014 Mar 15;9(6):653-60. doi: 10.4103/1673-5374.130117.

Current evidence shows that apolipoprotein E (APOE), apolipoprotein CI (APOC1) and low density lipoprotein receptor-related protein (LRP) variations are related to late-onset Alzheimer's disease. However, it remains unclear if genetic polymorphisms in these genes are associated with cognitive decline...

Cost-effective dye-sensitized solar cells consisting of two metal foils instead of transparent conductive oxide glass.
