MCM-41 based catalysts (molar ratio Si/Al = 40) were prepared by a hydrothermal route, modified ionic exchange with different metals (Cu, Cr, Fe and Zn) finally calcined at 550 °C. The fully characterized techniques that confirmed the formation of oxides on surfaces all materials. Low-angle X-ray diffraction (XRD) analyses showed calcination resulted in incorporation metallic Zn, Cr framework M...

A novel recycling process of the conductive agent in spent lithium iron phosphate batteries is demonstrated. Wet chemistry applied recovering and phosphate, filter residue calcined with a small amount recovered N2 at 900 °C to form FeNP-codoped carbon catalyst, which exhibits low half-wave potential excellent durability for oxygen reduction. When rechargeable Zn–air battery, power density can...

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

The crystal structure of a putative dipeptidase (Phdpd) from Pyrococcus horikoshii OT3 was solved using X-ray data at 2.4 A resolution. The protein is folded into two distinct entities. The N-terminal domain consists of the general topology of the alpha/beta fold, and the C-terminal domain consists of five long mixed strands, four helices, and two 3(10) helices. The structure of Phdpd is quite ...

In a combination of generation and storage hydrogen gas, both formic acid (FA) acetic (AA) have been notified as efficient carriers. This study was conducted to synthesize the monometallic catalysts namely palladium (Pd), copper (Cu), zinc (Zn) on graphitic-carbon nitride (g-C3N4) potential these in FA mixed (FA)-acetic decomposition reaction. Several parameters studied this work such type acti...
