Alternative Refrigerants For Household Refrigerators

, 2018
During the last decades, the energy consumption of household appliances was reduced continuously. The reason for this developments is caused by higher power costs and stricter statutory rules. To achieve these goals, it was necessary to improve and evolve each component of the cooling circuit as well as the insulation.

On the Ordering Mechanism of Cu+ in 2D van der Waals Multiferroic CuCrP2S6

Advanced Science, EarlyView.
Temperature‐dependent X‐ray single‐crystal diffuse scattering measurements of CuCrP2S6 in the (H, K, 0) plane reveal the gradual emergence and strengthening of short‐range order upon cooling from 230 to 170 K. At intermediate temperatures, diffuse features become pronounced and eventually lock into sharp incommensurate satellite reflections, indicating

Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM

Advanced Science, EarlyView.
Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Performance of ejector refrigeration cycle using a steady flow model

Revista Facultad de Ingeniería Universidad de Antioquia
A study of an alternative ejector cooling system is proposed in this paper. A mathematical model without irreversibility is developed and simulated. The numerical results are validated with literature data for two working fluids (R134a and R152a).

Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, EarlyView.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.
