The two stage circulating pump for a central heating system, has the two stages, (A, B) mounted on a common drive shaft (3) at the output of a single motor (4) each stage having a rotor which is about 55 mm. diameter. It can be used in a circuit with a vain heater and a ...

Laser cooling typically requires one or more repump lasers to clear dark states, which complicates experimental setups, especially for systems with multiple repumping frequencies. Here, we demonstrate cooling of Be+ions using a single laser beam, enabled by micromotion-induced one-dimensional heatin...
The driving force of a charge density wave (CDW) transition in quasi-two dimensional systems is still debated, while being crucial in understanding electronic correlation in such materials. Here we use femtosecond time- and angle-resolved photoemission s

Blue dashed circles demonstrate imaged anatomical sites in mice cortex. (B) Neutrophils (blue, PE-Ly-6G) swarmed into parenchyma from blood...
During and immediately after pump excitation, a strongly non-thermal electronic distribution develops, modifying the free energy potential (as inferred form the prompt AM softening discussed in Fig. 2b). Consequently, equilibrium parameters such as the temperature and the coefficient α(T) are poorly...
Using a neutral density filter, the fluence of the pump was adjusted to 150 μJ cm−2. The second arm was led through a delay stage and then used for white-light generation in a CaF crystal. The generated white light was then focused onto the sample with a spot diameter of 250...

The temporal contrast of the individual laser systems was characterised with identical measurement methods and instruments to ensure comparability. For this purpose, a 1-inch silver mirror was used to pick off a central part of the collimated laser beam before the final focusing optic and send it...
Plastic crystals as barocaloric materials exhibit the large entropy change rivalling freon, however, the limited pressure-sensitivity and large hysteresis of phase transition hinder the colossal barocaloric effect accomplished reversibly at low pressure.
