Abstract Atomic scale crystallographic structures of a quantum crystals depend on substrate, interfacial strain, defects, surface functionalities etc., which make it challenging to precisely control. To achieve high quality material, UHV conditions are prerequisite, makes costly. Naturally occurring 2D materials have tremendous significance in this regard. White lead, having weak interlayer cou...

Graphene is a 2-dimensional carbon allotrope consisting of thin layer sp2 atoms connected by van der Waals forces. Doping metal and/or the addition electrolyte to graphene structure can improve graphene’s conductivity properties. More details be found in article number 2100453, Rikson Siburian and co-workers.

Using physical activation, a new composite adsorbent was prepared by modifying low-cost local adsorbent. This also from activating sludge, bentonite, and limestone (SBL). In comparison to the LCL, adsorption capacity of improved. measured in terms its ability remove sulfate wastewater. The behavior processes using (SBL) as an investigated batch experiments examining different values solution pH...
