Validation of mid-infrared spectrometry in milk for predicting body energy status in Holstein-Friesian cows [PDF]

, 2012
Cow energy balance is known to be associated with cow health and fertility; therefore, routine access to data on energy balance can be useful in both management and breeding decisions to improve cow performance.

Sky‐Directional Radiative Cooling Meta‐Films for Daylighting Windows

Advanced Functional Materials, EarlyView.
A geometry‐mediated microprism meta‐film enables transparent, sky‐directional radiative cooling for daylighting windows. By decoupling control of visible transmittance from mid‐infrared emissivity, ground‐emitted heat absorption is suppressed while skyward heat dissipation is enhanced.

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo

Advanced Functional Materials, EarlyView.
In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...

Mid-infrared-perturbed Molecular Vibrational Signatures in Plasmonic Nanocavities

, 2021
Recent developments in surface-enhanced Raman scattering (SERS) enable observation of single-bond vibrations in real-time at room temperature. By contrast, mid-infrared (MIR) vibrational spectroscopy is limited to inefficient slow detection.

Mid-infrared laser filaments in the atmosphere [PDF]

Scientific Reports, 2015
AbstractFilamentation of ultrashort laser pulses in the atmosphere offers unique opportunities for long-range transmission of high-power laser radiation and standoff detection. With the critical power of self-focusing scaling as the laser wavelength squared, the quest for longer-wavelength drivers, which would radically increase the peak power and ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Mid-infrared photonics devices in SOI

In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm
