Entropy Decoding the Fundamental Law of Phase Competition in Glass Formation
Advanced Science, EarlyView.We validate the integration of intermetallic and eutectic phases as initial phases for composition design. The phase competition mechanism in glass formation is quantitatively clarified based on the melting entropy of competing phases. Glass‐forming ability is modulated by tuning phase competition via the melting entropy of initial phases.

Advanced Science, EarlyView.Operando gas diagnostics reveal a previously unrecognized chemical activation (CA) stage during thermal runaway in lithium‐ion batteries. A physics‐informed gas generation kinetics network (GGKNet) is developed to reconstruct reaction pathways and physical models automatically.

Calorímetro de gelo: uma abordagem histórica e experimental para o ensino de química na graduação
Química Nova, 2010 In addition to the usual advantage of an ice calorimeter of being able to measure slow heat changes, the instrument described here is extremely simple to construct and operate.

The Electromagnetic Calorimeter of CMS [PDF]
IEEE Transactions on Nuclear Science, 2005 The electromagnetic calorimeter of CMS at the large hadron collider (LHC) has been designed to measure the energy of electrons and photons with high resolution over a wide energy range. The detector consists of 61200 PBWO/sub 4/ crystals for the barrel and 14648 crystals for the endcaps, with a pseudo-rapidity coverage of |/spl eta/| /spl les/ 3.0 ...

Advanced Science, EarlyView.We present a stimulus‐replicating system combining a tactile sensor with a wearable Peltier thermotactile module and concentric electrotactile electrode. Signals encoding pressure and temperature drive the stimulators to reproduce mechano‐thermal cues on the skin. AlN/PDMS encapsulation and SA/LA PSA ensure mechanical compliance and thermal efficiency.
