Hydrogen bonding in enantiomeric versus racemic mono-carboxylic acids; a case study of 2-phenoxypropionic acid.

Acta crystallographica. Section B, Structural science

Sørensen HO, Larsen S.
PMID: 12554978
Acta Crystallogr B. 2003 Feb;59:132-40. doi: 10.1107/s0108768102022085. Epub 2003 Jan 28.

The structural and thermodynamic backgrounds for the crystallization behaviour of racemates have been investigated using 2-phenoxypropionic acid (PPA) as an example. The racemate of PPA behaves normally and forms a racemic compound that has a higher melting point and...

Dependability of wind energy generators with short-term energy storage.

Science (New York, N.Y.)

Sørensen B.
PMID: 17748551
Science. 1976 Nov 26;194(4268):935-7. doi: 10.1126/science.194.4268.935-a.

Power fluctuations and power duration curves for wind energy generators, including energy storage facilities of a certain capacity, are compared to those of typical nuclear reactors. A storage system capable of delivering the yearly average power output for about...

Oxidation fronts in pelagic sediments: diagenetic formation of metal-rich layers.

Science (New York, N.Y.)

Wilson TR, Thomson J, Hydes DJ, Colley S, Culkin F, Sørensen J.
PMID: 17759281
Science. 1986 May 23;232(4753):972-5. doi: 10.1126/science.232.4753.972.

The periodic deposition of distal turbidites at a site on the Madeira Abyssal Plain causes the development of a nonsteady-state diagenetic system in which an oxidation front migrates downward into the sediment. Data presented here show that iron, manganese,...

Formation and subdivision of deformation structures during plastic deformation.

Science (New York, N.Y.)

Jakobsen B, Poulsen HF, Lienert U, Almer J, Shastri SD, Sørensen HO, Gundlach C, Pantleon W.
PMID: 16690859
Science. 2006 May 12;312(5775):889-92. doi: 10.1126/science.1124141.

During plastic deformation of metals and alloys, dislocations arrange in ordered patterns. How and when these self-organization processes take place have remained elusive, because in situ observations have not been feasible. We present an x-ray diffraction method that provided...

Depression in COPD--management and quality of life considerations.

International journal of chronic obstructive pulmonary disease

Stage KB, Middelboe T, Stage TB, Sørensen CH.
PMID: 18046868
Int J Chron Obstruct Pulmon Dis. 2006;1(3):315-20. doi: 10.2147/copd.2006.1.3.315.

Depression is common in COPD patients. Around 40% are affected by severe depressive symptoms or clinical depression. It is not easy to diagnose depression in COPD patients because of overlapping symptoms between COPD and depression. However, the six-item Hamilton...

Influence of the oxide layer for growth of self-assisted InAs nanowires on Si(111).

Nanoscale research letters

Madsen MH, Aagesen M, Krogstrup P, Sørensen C, Nygård J.
PMID: 21880130
Nanoscale Res Lett. 2011 Aug 31;6:516. doi: 10.1186/1556-276X-6-516.

The growth of self-assisted InAs nanowires (NWs) by molecular beam epitaxy (MBE) on Si(111) is studied for different growth parameters and substrate preparations. The thickness of the oxide layer present on the Si(111) surface is observed to play a...

Electrostatic spraying:  a novel technique for preparation of polymer coatings on electrodes.

Analytical chemistry

Hoyer B, Sørensen G, Jensen N, Nielsen DB, Larsen B.
PMID: 21619258
Anal Chem. 1996 Nov 01;68(21):3840-4. doi: 10.1021/ac9605509.

A liquid flow emerging from a tip or a thin tube under the influence of a strong electric field will, due to charging of the dielectric liquid, break up into small droplets. Thus, if a polymer material is dissolved...

Assessment of undiscovered oil and gas in the Arctic.

Science (New York, N.Y.)

Gautier DL, Bird KJ, Charpentier RR, Grantz A, Houseknecht DW, Klett TR, Moore TE, Pitman JK, Schenk CJ, Schuenemeyer JH, Sørensen K, Tennyson ME, Valin ZC, Wandrey CJ.
PMID: 19478178
Science. 2009 May 29;324(5931):1175-9. doi: 10.1126/science.1169467.

Among the greatest uncertainties in future energy supply and a subject of considerable environmental concern is the amount of oil and gas yet to be found in the Arctic. By using a probabilistic geology-based methodology, the United States Geological...

Non-haem iron availability from pork meat: Impact of heat treatments and meat protein dose.

Meat science

Sørensen AD, Sørensen H, Søndergaard I, Bukhave K.
PMID: 22064188
Meat Sci. 2007 May;76(1):29-37. doi: 10.1016/j.meatsci.2006.10.008. Epub 2006 Nov 29.

Pork meat heated at 60, 80, 100, and 120°C (1h), raw pork meat, BSA, casein and haemoglobin were examined for their effects on in vitro iron availability measured as Fe(2+)-dialysability, and on iron-reducing capacity following in vitro protein digestion...

Mode field diameter preserving fiber tapers.

Optics letters

Noordegraaf D, Maack MD, Skovgaard PM, Sørensen MH, Broeng J, Lægsgaard J.
PMID: 22139230
Opt Lett. 2011 Dec 01;36(23):4524-6. doi: 10.1364/OL.36.004524.

An approach for preserving the mode field diameter (MFD) in fiber tapers is demonstrated. The approach utilizes concentric dual-core fibers, which couple light from an inner core to an outer core through a taper. Fibers with a 6 μm...

Oxidation in pre-cooked minced pork as influenced by chill storage of raw muscle.

Meat science

Nielsen JH, Sørensen B, Skibsted LH, Bertelsen G.
PMID: 22062042
Meat Sci. 1997 Jun;46(2):191-7. doi: 10.1016/s0309-1740(97)00016-8.

During storage for four days at 4 °C of pre-cooked minced pork, lipid oxidation measured as thiobarbituric acid reactive substances (TBARS) and as hexanal by solid phase microextraction was found to depend on the level of lipid hydroperoxides rather...
