Product Overview

The MAX phase is A ternary layered ceramic material, where M is a transition metal element, A is mainly a third and fourth main group element, and X is carbon or nitrogen. The crystal unit arrangement of this material is hexagonal structure, and the space point group is P63/mmc, where the M atomic layer and the A atomic layer are alternately arranged to form a layered structure similar to the close-packed hexagonal structure, and the X atom is filled in the gap position of the octahedron. Where M is the pre-transition metal element, A is the main group element, X is the carbon or nitrogen element, n= 1,2,3, so it is referred to as the MAX phase. When n=1, it is 211 phases, such as Ti2AlC and Ti2SiC; When n=2, it is 312 phases, such as Ti3SiC2 and Ti3AlC2; When n=3, it is called 413 phase, such as Ti4AlN3. MAX phase synthesis is mainly prepared by mixing raw material powder by ball milling and then sintering at high temperature. A new two-dimensional nanomaterials, MXene, is A new two-dimensional carbon/nitride nanolayered material prepared by using the weak binding force between the A layer and the MX layer in the MAX phase and selecting suitable etching agents (such as HF, LiF+HCl, NH4HF2, etc.) to denudate the A atomic layer in the MAX phase. It has good electrical conductivity and hydrophicity. A variety of 2D MXene materials such as Ti3C2Tx, V4C3Tx, Nb2CTx and Ti2CTx have been synthesized successfully. The general formula can be expressed as Mn+1XnTx, where Tx represents the functional groups (-OH, -F, -O, -Cl, etc.) attached to the surface of MXene by chemical etching of the precursor MAX phase. Multilayer MXene can be stripped into single-layer MXene nanosheets by ultrasonic crushing or ball milling, whose morphology is similar to that of graphene.

Simple AND essential, everyone should read
Format: Kindle
I've been Christian for many years, reading many books, sermons, biblical readings, but we never stop having more beautiful insights of this glorious Christian path laid before our minds and hearts. This book is a wise, beautiful, encouraging, and simply amazing way to see and live out the Christian life and calling, rich with meaning in our current broken world and the redeemed and restored world in Christ. Are you yearning for real spirituality, joy, justice, beauty, relationships, but they seem somehow out of reach? Read this book. It is simple yet profound. Take the time to savor the words of this book alongside prayer, biblical reading, community, daily work...And partake in the overlap of heaven and earth with the Lord.

Why "Simply Christian" is a "must read"
It presents a compelling case for Christianity without attempting to bully the reader (as C. S. Lewis often does in his essays) and without relying on all those "code words" that long-time Christians find familiar but others do not. This is the Gospel in plan English. Bravo! It firmly insists that Christianity makes claims about history - that Jesus lived, died, and rose again, and that this resurrection is the central event in the story of God's re-creation of our fallen world. It insists that Christians be active participants in the future unfolding of God's plan. We are each called to play a unique role in it. It insists that there is a transcendent realm, another world, that can and does intersect or overlap with our own world, especially in sacraments, in worship, in Bible reading, and in prayer. Moreover, just as the temple was, for Jews in Jesus time, a place where heaven and earth overlapped, now we, as individual Christians, are called to be such places of overlap, where the light of Jesus shines through us. It highlights the crucial importance of forgiveness. Just as God has forgiven us our sins, so are we to forgive others. The Lord's prayer is explicit on this point. Becoming a Christian, Wright asserts, is not a matter or accepting certain improbable factual assertions, but rather a matter of trusting in God and accepting our role in unfolding his plan for the world. Rather than being dissected, as in a laboratory, or treated merely as an instrument of historical or linguistic research, the Bible is in fact one of the principal ways in which God addresses us, to prepare us for our role in fulfilling his ultimate plans. It is another place where this world and God's world overlap. Current debates over "literal" versus "metaphorical" ways of reading scripture are, in Wright's view, counterproductive. The Bible eludes these simplistic categories, which should be abandoned. At its core, then, the "faith" to which the Bible calls us is essentially trusting in a God who has revealed himself in history, who has begun, through Jesus' death and resurrection, to redeem the world and transform it into his kingdom, who invites us into to an intimate relationship with him, who demands that we become all that we were created and meant to be, who forgives us when we fall short of that mark, and who invites us to play a significant role in moving forward his plan for the world. For Wright, Christian faith is not just a matter of spiritual feelings that are quite independent of what we say and do. It makes demands upon us that can only be met in the realm of thought and behavior. As C. S. Lewis did in his fiction, "Simply Christian" persuasively invites its readers to recognize that there is a transcendent reality that impinges on our ordinary world, that the God who rules this realm has made himself known in history and continues to do so, that we are part of his plan to renew his creation, and, consequently, that what we think and do has cosmic significance.

Interesting, but no Lewis
Format: Paperback
Some books can be completely conveyed in about eight sentences or a couple paragraphs. This is one of them. Everything else beyond the core thesis is unnecessary or repetitive. This book probably would have made a good article. Wright is a well known Pauline expert, but in this book he takes a step out of his comfort zone. I usually find Paul rambling and confusing enough, so I look to experts like Wright to clarify Paul for me. But in this book, Wright seems to put on his Paul hat and just reiterates Pauline gobbledy-gook. Throughout, he presents long passages comprised solely of Pauline quotes. This book is billed as an updated version of C.S. Lewis’s “Mere Christianity.” Both Wright and Lewis are seeped in their Anglican tradition. But where Lewis looks at the various Christian denominations and identifies what’s common and good among them all, Wright sees differences and insists they are all wrong. In alienating evangelicals on the one hand, and Catholics on the other, Wright suggests that to be Simply Christian you must abandon your faith traditions that are at odds with his. I can’t imagine Lewis taking this tack. I give this three stars, for its clear style, for being thought provoking, and for its call to personal introspection.

Great Daily Vitamin
Size: 100 Count (Pack of 1)
I needed a daily vitamin but didn't know where to start, so this was my 1st choice. I don't know specifically what I was lacking in my daily diet, but within a week of taking these, I felt much more energetic than before. Been using them for approximately 2 months now and I will be purchasing them in the future. Pricing is within reason.
