This manuscript describes a simple and rapid method for fabricating free‐standing structures composed primarily (>94% w/w, and 55–80 at%) of noble metals (e.g., gold, silver, platinum, etc.) and having physical morphologies that resemble paper, thread, or fabric. In this method, templates (i.e., pieces of paper, or cotton fabric) are loaded with aqueous solutions of salts of noble metals, and then the cellulosic component is burned off in a furnace held at high temperatures (i.e., from 550 °C… 
Biomass-Templated Fabrication of Metallic Materials for Photocatalytic and Bactericidal Applications
A simple, feasible and low-cost method to fabricate self-standing metallic materials using cellulose-based biomass as sacrificial templates and the transformation of the precursors to corresponding metals or metal oxides at an elevated temperature is reported.
Inexpensive, Three-dimensional, Open-cell, Fluid-permeable, Noble Metal Electrodes for Electroanalysis and Electrocatalysis.
This study describes the fabrication of three-dimensional, open-cell, noble metal (Au, Ag, and Pt) electrodes that have a complex geometry i.e., wire-mesh, metallic foam, 'origami' wire-mesh, and
Delayed Capillary Flow of Elastomers: An Efficient Method for Fabrication and Nanofunctionalization of Flexible, Foldable, Twistable, and Stretchable Electrodes from Pyrolyzed Paper
Pyrolyzed cellulose‐based materials are extensively used in many fields for many different applications due to their excellent electrical properties. However, pyrolyzed materials are extremely

Inverting Thermal Degradation (iTD) of Paper Using Chemi- and Physi-Sorbed Modifiers for Templated Material Synthesis
It is demonstrated that chemi- and physi-sorbed modifiers of cellulose alters the thermal degradation mechanism allowing for controlled deposition of oxide and carbon (incomplete combustion) along the original paper fiber network.
Laser-induced electrodes towards low-cost flexible UV ZnO sensors
Flexible electronics is a branch of electric fabrication that allows for increasingly ergonomic devices. However, its production still requires multi-step, expensive, and time-consuming processes.
Multifunctional metallic backbones for origami robotics with strain sensing and wireless communication capabilities
The multifunctionality of Pt robots was further demonstrated to extend beyond the capabilities of traditional paper-based robots, such as melting an ice cube to escape, monitoring/recording robotic motions in real time, and wireless communications between robots.
Cheap, Flexible, and Thermal-Sensitive Paper Sensor through Writing with Ionic Liquids Containing Pencil Leads.
The as-prepared paper sensor was very sensitive to the NIR irradiation and warm objects and had regular responses along with the varication of the folding angles, which could be employed for the angle goniometer of electronic robots.

Hollow metal oxide fibers (TiO2 and Fe2O3) have been prepared by using activated carbon fibers (ACFs) as the templates, through a simple impregnation and heat treatment. The resulting products, as
Preparation of Macroporous Metal Films from Colloidal Crystals
Template-directed syntheses have been broadly applied to the creation of both mesoand macroporous ceramics1-4 and polymers.5 The extension of such methods to metals is of particular interest.
Bioinspired templating synthesis of metal-polymer hybrid nanostructures within 3D electrospun nanofibers.
