Study on the Influence of Slope Static Load on Shallow Lining Support Structure

open access: yesEnergy Science &Engineering, EarlyView.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

Study on Deformation Law of Crossing Layer Drilling Superimposed Floor Roadway

open access: yesEnergy Science &Engineering, EarlyView.
Based on deformation law of crossing layer drilling superimposed floor roadway, low dip angle drilling is particularly susceptible to complications such as borehole blockage and collapse. ABSTRACT Floor extraction roadway crossing layer drilling is a pivotal strategy for gas control in areas prone to coal and gas outbursts.

Low‐temperature soft electrochemical actuator based on hierarchically structured polypyrrole membranes for subzero operation

open access: yesFlexMat, EarlyView.
A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Quantitative Correlation Between Charge Transfer and Two Photon Absorption in Phenanthridine‐TCNB Cocrystal

open access: yesInformation &Functional Materials, EarlyView.
A new molecular cocrystal shows D‐A alternative molecular stacking, cyan‐blue photoluminescence with lifetime of 19.76 ns, and two‐photon absorption enabled emission under laser excitation between 720 and 880 nm. Theoretical calculations reveal its static dipole moment of 2.84 D, CT character in the ground, S1, and S2 excited states, and the TPA ...
