Experimental analysis of noise reduction properties of sound absorbing foam [PDF]

, 2001
Plan BWood dust deposition had both positive and negative effects on the sound absorption properties of acoustical foam. Three layers of wood dust were deposited on acoustical foam in a 2.44 meter by 2.44 meter by 2.44 meter Plexiglas test chamber.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially
