Application of Shock Absorber based on Bit-rock Interaction
Shiyou jixie, 2022 In order to obtain the optimal parameters of shock absorber and thus reduce the downhole vibration intensity in the process of rock-breaking drilling of bit,on the basis of considering the dynamic coupling of drill string,bit and rock system,taking the ...

Predicting Enzyme Turnover Numbers and Enabling Rational Enzyme Evolution
Advanced Science, EarlyView.MCKcat, a deep learning framework combining multi‐scale convolution and cross‐attention, accurately predicts enzyme turnover number (kcat) by fusing sequence and reaction representations. It couples with rational design in a two‐step strategy for Bacillus aryabhattai laccase engineering, achieving a 75% positive rate with synergistically enhanced ...

Advanced Science, EarlyView.An injectable bimodal TCPD nanodepot disrupts glutaminolysis and TCA metabolism, sensitizing large tumors to spatially complementary sono‐thermal ablation for complete treatment coverage. This intervention induces mitochondrial and endoplasmic reticulum dysfunction, genotoxicity, and NAD+ depletion, converging to trigger PANoptosome assembly and ...

Advanced Science, EarlyView.A sandwich‐structured aramid composite paper was designed to integrate high corona resistance and thermal conductivity. The fluorinated graphene/aramid surface layers effectively dissipate space charges to suppress corona discharge. Meanwhile, the boron nitride nanotube/aramid core layer constructs continuous heat‐conduction pathways.
