Small Methods, EarlyView.Microspectroscopy combines a standard optical microscope with a spectrometer to measure reflectance and transmittance of samples down to the microscale. A numerical formalism that explicitly accounts for the high numerical aperture of magnifying optics retrieves complex refractive indices.

Tunable Dual-Wavelength Fiber Laser Based on a Polarization-Maintaining Fiber Bragg Grating and a Hi-Bi Fiber Optical Loop Mirror¹ [PDF]
, 2011 We demonstrate experimentally the operation of a linear cavity dual-wavelength fiber laser using a polarization maintaining fiber Bragg grating (PM-FBG) as an end mirror that defines two closely spaced laser emission lines.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The copper(I) thiocyanate adduct with thiuram disulfide, CuSCN[(SCNH2)2S2], was synthesized via mechanochemical grinding of equimolar amounts of CuSCN and (SCNH2)2S2 with minimal acetone. Structural analysis using PXRD data reveals infinite zigzag chains of distorted tetrahedra around copper along [001], interconnected into two‐dimensional wavy ...

Reflectivity-modulated grating-mirror
, 2012 The invention relates to vertical cavity lasers (VCL) incorporating a reflectivity-modulated grating mirror (1) for modulating the laser output. A cavity is formed by a bottom mirror (4), an active region (3), and an outcoupling top grating mirror (1 ...

ANZ Journal of Surgery, EarlyView.ABSTRACT Background The symptomatology of large hiatus hernia (LHH) has been historically poorly understood, with cardiorespiratory symptoms caused by LHH being underappreciated by clinicians. This study reports on the mechanisms of dyspnoea in LHH through a historical review of symptoms and evolved physiological literature, discussing likely causation.

Boreas, EarlyView.Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Cladistics, EarlyView.Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Coloration Technology, EarlyView.Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Quantification of Sulfur Speciation in Apatites: Comparison of the XAS, XPS and EPMA Techniques
Geostandards and Geoanalytical Research, EarlyView.Key Points Sulfur speciation in apatites has been determined by S K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy, S 2p X‐ray photoelectron spectroscopy (XPS) and electron probe microanalysis (EPMA). XANES provides the most sensitive and accurate quantification of sulfur speciation.
